Q. My Spark Plug needs replacing, what should I use?
Most Spark Plugs for Motofino Scooters use 10MM threaded plugs. We like the NGK spark plug. The R in the number indicates a resistor type plug, which means it is quieter in producing static and radio interference to nearby radios. The 6, and the 7 number indicate the operating heat range of the plug, with 7 a colder plug. If you do a lot of long trips over several hours perhaps a 7 would be good for you. A 6 is used for short frequent trips, and has the hottest spark for complete fuel burning.
Heat range has nothing to do with the spark plug contributing heat. None do! Rather, it is a number that indicates the ability of the plug to dissipate heat.
All plugs are more or less "tortured" in the cylinder. If the plug is too cold, its electrodes will never reach the optimum operating temperature to self clean its electrodes. It will foul sooner and have a shorter life. A hotter plug, will come up to operating temperature sooner. A big part of keeping your spark plug working optimally is keeping your air filter clean! The reason is a dirty air filter causes the air/fuel mixture to richen, which fouls any plug sooner in a Scooter.
Q. My 50cc Scooter seems to have worn out the CVT drive belt too quickly, why?
The fact is 50cc scoots are not designed for running at wide open throttle settings constantly, and for long periods of time. This is because there is tremendous heat
build up on the belt with WOT all the time. This will cause accelerated belt wear and cause the belt to disinegrate prematurely. A good idea is to remove the CVT
transmission cover periodically and inspect the condition of the plastic variator cooling fan, and blow out the black fan dust in the case. Check and see the case
air-vent is not plugged. If you inspect and service the guts of you transmission, replace plastic fan guide and rollers that may be flat, That and slowing down to
cool the case a little will keep the belt lasting a longer time. Obviously the 125 and 150cc Scoots don't usually have the same problem. It is well to note that "Jack Rabbit" get offs all the time will snap a belt in short order! Run the machine within its design limits.
Q. Can I pressure wash my engine compartment and my Scooter?
Not really a good idea. That's not because the parts in the scooter are that fragile, but consider these points.
1. Anytime by whatever method you use to wash the engine, it should be cool and not hot.
2. After finishing washing the engine area, start it to let heat assist with evaporating remaining water.
3. Realize that if any water has ingested into the carburetor, or air box intake, you may not be able to start the engine at all! Cover air-box intake tube if you wash!
4. Using a pressure washer can forcefully inject water past gaskets and seals, inject moisture in copper wiring and create general parts Havoc! Don't risk it!
5. A better safer way to wash the engine and area is to use a squeeze bottle sprayer containing dishwashing detergent and water. Spray the detergent on the area liberally and let stand about ten minutes. Then rise it with a water using a hose and low pressure. Follow up with an air hose blasting to remove excess moisture, then start the engine to evaporate remaining water. Washing the engine always creates some risk of parts damage. Just blow it out with low pressure compressed air when really bad, and use a stiff bristled brush to dislodge dirt. You can always wash any non-electrical part like wheels, covers etc. Use a soapy wet rag and brush!
Q. I have lost my spare ignition key. Is there an easy way to get another one?
Ace Hardware stores sometimes stock a key blank called the LLCOx121. They can cut you another one while you you wait. If they don't have that blank ask them to order it! Or, you can order a blank from ECOBIKEUSA. Click this.
Q. What should I know about my Scooter tires?
1. Keep them inflated to the manufacturer's recommended pressure. This information is on the tire itself. Only inflate when the tires are cold. The Motofino factory ID tag on the Scooter does recommend a slightly lower pressure for front tires as opposed to the rear tire for better steering control, which is good. There isn't always an ideal center of gravity with driver weights varying so much. Know in general that significantly under-inflated tires wear out sooner, slow your top speed, and ultimately result in tire failure caused by excessive tire wall flexing.
2. Keep tire valve stem cover caps screwed on the tire valves. Replace them if missing. The cover cap protects the valve stem air seal.
3. Look for road cuts in the sidewalls and tread. Use a pointed object to pick out any gravel, metal fragments, or pieces of glass you find lodged in the tread. Replace damaged tires and do not drive the Scooter until you do!
4. New Scooter tires do not grip the road well until the tread surface roughens a little through road contact. Be aware of this fact, and don't lean agressively until you've driven those tires a few miles.
Q. My Scooter runs for several minutes then dies, the motor quits. What happened? I wait awhile and it starts again! Most likely probems...
The gas tank rubber lip gasket has swollen and shut off flow air access to the gas tank. Scooters are a gravity feed with no fuel pump. The gas must flow from the tank, but if the gas tank has become air-tight, your scooter will starve for gas and quit. On some scooters the gas lid seals too tightly because gasoline has swollen the rubber gasket shutting off the air. You could just get a new gas cap, but I like to put a dent in the gas tank lip with a chisel and hammer blow. The little indent I cause makes an airflow port. T
hat unnoticeable dent will provide air flow. Sometimes a spark cap plug is loose. Check it! Rarely, the spark plug cap is intermiitent, or goes open internally. Check for continuity through the spark plug cap, by twisting out the spark lead wire. It should read no more than 5,000 Ohms resistance. You have kink in your fuel line. Check to see gravity feed line is clear and supported. Your vacuum line is leaking at the intake manifold connection nipple. -if leaking it will shut off, or restrict fuel flow from the Gas tank. It depends on vacuum to operate. Your fuel filter is clogged. Replace.
Your Spark plug goes open internally when heated - Replace. Your Spark Coil connection wire plug tabs are loose. Push them back on connection tabs.
Q. What about Brake Pads?
Sure, We have them. What model is it for? obviously the ability to stop is critical! You can order brake pads or bands and replace them when you discover you've used them to a point you can't adjust the control cable to compensate. It is true using both the front and the rear brake to slow or stop, together, will make both of them last longer. That and slowing down by reducing your power setting on the throttle when you know you are going to stop. Your Front Brake has the most stopping power.
If you need instructions on how to replace brake pads or replace DOT 3 brake fluid in your Scooter brake resevoir, check your manual. If still confused call us.
Q. I have a Motofino MF50QT-6, do I need new drum brake shoes?
Depends on whether or not you've adjusted them all the way tight and still have no stopping action. Note that the brake travel is individually adjustable on both the front and rear wheels with a screw detenting adjustment nut. Put your scooter on its stand and adjust these by turning each of them in. This removes some brake contol cable slack in your handlebar controls too. It is quite unlikely you need to replace brake shoes if you have little mileage indicated on your scooter. What is does mean is they probably were not adjusted correctly when the scooter was set up. While you are making the drum brake adjustment, spin the wheel by propping up the front wheel so it will turn freely. Do not adjust so tight you detect a drag on the wheel. Adjust the rear wheel the same way.
If the wheel sqeaks a little from time to time, it means a little dirt or debris is in the brake shoe and wheel. This is happens sometimes when the scooter only has a couple hundred miles on it and will go away. The lining of brake shoes is a hard composition, not soft and smooth so sometimes they may squeak a little.
If in fact you do need new brake shoes for your 50QT-6, because adjustments are all the way tight, be aware they are not exactly the same size for both the front and back shoes. Be sure and specify what wheel the new brake shoes go on, front or back wheel? New brake shoes come with new springs.

Q. Where can I find important specification data about my Scooter?
A.
On the front, inside cowl cockpit of the scooter is an EPA required
aluminum label plate. Stamped information for engine displacement, engine family type, slow idle RPM, type of SAE motor oil, Spark plug gap, and other essential information is die stamped on this plate.
The vehicle VIN number, uniquely identifying this vehicle can be found stamped in the steel of the steering column tube. You have to remove a small retangular black plastic cover in the cockpit cowling, under and below the specification label to see it. With some scooters you are the one that snaps the cover in place because it was in the bag with your spare key and instruction booklet.
Q. What should I use to clean off bugs and road tar from my Scooter?
Always try and use soap and water first. and the sooner you do the better! Whatever you do, under any circumstances, do not use an alcohol content cleaner! Do not use any surfactant containing ammonia, or soap containing a bleach or abrasives! For the really tough bug stains and road tar the most effective thing you can use is plain old Kerosene, (Lamp Oil) on a rag for body panels. Use only soap and water for light lenses and other plastics. By soap and water, we mean a solution of liquid hand dish washing detergent and water. That does not include things like 409. but slightly acid citrus oil based cleaners are OK.
Q. What can I use to remove fogged lenses on my Scooter dash, headlights, or whatever without damage?
A
.
You can
remove light oxidation, chemical degradation, surface contamination, stains and light surface scratches with ease, using a polishing liquid called Meguires PlastX. This stuff really works! It is a micro-abrasive. Very effective for a rougher blemish when a clean damp sponge is tied on a spinning drill or something so you can save yourself some elbow grease rubbing! It takes a lot of polishing sometimes to completely remove a blemish in clear plastics It does make them optically clear again. Rinse off polished area and final polish with cloth. Special highly water resistant polymers provide long lasting durable protection to keep your clear plastics clear and beautiful longer. Works great on tailights and other plastic colored lenses.
A. Use a "paint on" product called Liquid tape. Clean the area as best you can and apply. This will waterproof small scooter components like starter relays, etc. Caution- Read label before using. Flammable. Vapors harmful.
Bob approves of Performix brand. He teachs small engine mechanics in Florida.
Bob from St.Augustine, FL is a mechanical whiz at scooter repair, and highly recommends this product "Devcon Plastic Welder." Bob says unlike cements like JB Weld or whatever that depend on glued surface roughness, Devcon actually
melts the ABS panel surface somewhat, fusing the plastic parts together as strong as new. Obviously you do not want to get the stuff anywhere except the joint you are bonding! This can save you the cost of a part!
Bob advises you keep this stuff refridgerated after opening.

us that Motofino belts wear much better and last longer than other types, including some Kevlars. They are genuine Bondo.
To replace a scooter CVT belt - The first order of business is to remove kick starter pedal and pry if off the splined shaft after loosening it's tightening bolt about six turns. Slide the kick-starter off. Now you have 8 each - 8MM short bolts surrounding and holding the transmission cover on. Remove all the bolts, starting with the lower ones first, and then top ones, leaving one topmost bolt holding the cover on. Now remove the last bolt while holding the cover in place, and pull the transmission cover toward you to remove it. This job is a lot easier if you have a Motofino Service Manual CD.
When you do it, move slowly so you do not displace the starter return spring, and have it fall away before you can see how it is oriented when in place. You may destroy the paper case gasket too, but that is no biggy. Just use RTV Slicone to put around the case lip when you re-install cover it you want to, or do without a gasket. Not really a necessity to have one.
Once the cover is off you will have a view of the inside of your CVT pulleys, and the old belt. The next thing to do is take an air-hose and blow out all the black dust and remove the particles left from the old belt wear destruction.
Explode the pictures
at the left
. The far left pulley is the drive pulley, with the variator behind it, and behind that is your rollers in the variator. The pulley on the right is the clutch pulley. You don't have to work on that pulley to change a belt, only move it by hand maybe.
To take off the old belt and install the new on - You must first remove the left (front) drive wheel pulley nut. This can only be easily done using an impact air-driven wrench, or an electric wrench with good speed. If you just try to use a regular socket wrench the pulleys will turn, getting you nowhere! Impact wrenches will zip the nut off quickly. Now pull off the washer and remove the outside pulley half, and inner metal shaft sleeve. There are cooling fins on the outside pulley half, forming a cooling fan. On 50cc scooters the fan is plastic. If melted or malformed, replace it as a separate piece from the outside metal drive pulley half. Now pull off the old belt. Next, put the new belt on, working it in the groves on the right clutch pulley first. Your new belt is stiff, and at full width, so to get enough slack to slide it in place on the front drive pulley shaft, you may have to grasp the rear clutch pulley and spread it with your hands to slide the belt in enough to get the slack for putting the new belt on the front pulley shaft. Now lube the shaft points shown in the lower picture, sparingly with a high temperature grease.
Finishing up and re-assembly - Iightly oil and slide on the front pulley shaft sleeve only, inside shaft contact surface metal pulley half, but not the plastic fan, if separate.put the washer on the outside back on, then start the pulley holding nut by hand and hand-tighten. Use blue locktite on the threads if you like. Use an impact gun to tighten the pulley on securely. You need a torque of 28 ft,/lbs. Then oil the 8mm cover holding bolt and put the cover back in place. Only tighten these bolts to 7 ft/lbs. Max. Replace the kick-starter on the splined shaft being sure the kick starter return spring is in place. Tighten the kick start pedal bolt to secure it to the starter shaft.

Motofino Scooter Maintenance Q and A: For Motofino Owners
Q. What can I do to keep my Motofino mechanically in top shape?
You can keep your oil changed every 750 to 850, miles, and use Synthetic Blend oil
Castrol Synthetic Blend in 10W-40 weight. The oil required is 25 to 28 ounces, depending on engine size, so it amounts to less than a quart. You can use the same oil in your transmission oil flller port. The amount varies by CC required, which is stamped on the particular model CVT metal case. Although the CVT uses no oil itself, you are lubricating a geared mechanism.
Q. What else mechanically is really important?
Use unleaded gasoline rated at 90 Octane or better. Your engine is a high-compression 4-cycle. 90 octane fuel is needed so ignition occurs optimally, at just the right time in the cylinder. Keep your throttle, brakes, controls and cables inspected. Check for any loose bolts in muffler attachment, and inspect your wheel nuts regularly to detect any loosening. Loose bolts anywhere on the machine may pose real danger to the rider and create other repairs. Stop and check your header nuts that attach the muffler pipe to the engine. Be sure they are tight! Do it every 6 months. Maybe apply red Locktite??
Q. My Scooter doesn't seem to run as well as it did when I first got it. Do my valves need adjustment?
Motofino scooters should have adjustment of the intake and exhaust valves after a few hundred miles, for optimum performance to be acheived with good engine power and speed.
Sometimes the valve lash clearance is set a little tight preventing the intake and exhaust valves from opening fully. This causes a severe loss of power. You will notice on new Motofino Scooters, you cannot really hear any valve noise when the engine is running. Not that you should, however, a slight noise is acceptable if the valve set nut and adjstment is secure and still correct. The way you loose power with too little valve lash clearance is, the valves do not fully open long enough to grab the optimal amount of fresh fuel, or expell exhaust burned gases. Valve lash adjustments must be done on a cold to the touch engine. Never do it when the engine is hot or warm.
Valve lash adjustment is not "rocket science" and anybody with a little tool savy can do it. For others, it is best to have a scooter mechanic or your Motofino dealer do it for you. The correct clearance is a snug .004" for the intake valve and .005" for the exhaust valve. One way to remember which is which, is the intake valve is physically closest to the carburetor on the intake manifold side.
To remove the valve cover remove four bolts. When you put the cover back on tighten evenly to 7 inch pounds.
Remove the fan cover to expose the cooling fan. Once the cover is off you can see the markings scribed in the flywheel behind the fan, and a protrusion on the engine case which is the reference indicator pointer. (The two photos at the left explode to a larger size if you click on them.)
Once you have removed the valve cover to expose the valves, you have to grasp the engine cooling fan and use it to move the flywheel mark to "T," aligned with the case pointer. If you look at the timing cam wheel in the valve head, you will also see there are two small holes in that camwheel that are perfectly aligned parallel with the lip of the top of the valve-head assembly. Once you have the valves in the correct time position, you can proceed with adjusting them.
Loosen the 10mm valve set screw nut. Slide a flat feeler guage under the valve rocker arm contact point, between it and the top of the particular valve stem. Then use a flatblade screwdriver to adjust the clearance for a snug fit on your feeler gauge. It should take a slight pull to remove the feeler gauge from contact from under the rocker if set correctly with the engine cold.
Using your flatblade, with the feeler gauge still inserted under the valve rocker arm. tighten the valve lock nut while holding the setting in postion with your screwdriver. Pull the feeler gauge a bit again to see that you didn't change the clearance setting. Now remove your feeler gauge, change its thickness value and move to the next valve and do it. If when you start the scooter the valves are excessive noisy, you made the lash too loose, so it clickity-clacks! Relax, you haven't hurt anything. You just have to wait a few hours for the engine to cool so you can go at it again!
