tmarie,

You say you can hear the starter spin but does not turn the motor right? SOunds like the starter chain may have broke or came off. You have to remove the left cover on the motor and you can see the chain and starter gear. This way you can see what it is not doing. You can remove the cover by removing 5 bolts then just pull out on the cover.

 

The chain spins both gears but does not engage the motor

 

hi i have the same problem kind of I have a kazuma 110 and it ciesed it had no oil in the engine anyway we got it rebuilt and the battery would not charge then after about 3 days of non stop riding it started to charge when it finally got enough charge to get the starter motor going it would get a flat battery trying to start it and now the battery doesent charge and when i hook it up to a car battery the starter spins , i get spark but the engine doesent start it was fine until we got it rebuilt and when i rang up the shop that i bought it from they said that it wouldent have anything to do with the rebuild but it obviously does

thanks for your time dan

 

yes i had that problem! first try putting it gear and then push it just a little bit, if that does not work ,you need new starter. if you just got them , carey it back to the seller, it should be under warannty for 6 months

I know this was an old post but my son put his atv in the mud and its doing the same thing it ran fine till he stopped it then it wouldnt start. There was mud in the starter case cover so i cleaned it out and it started right up but i tried it the next day and the starter just spins. The chain is moving but it wont engage the wheel please help . Jeff

 

What was the resolution? Replacing the starter? I did not see it completely, please advise.
Thank you.

 

I had the same problem after getting into deep muddy water and then driving it.
The starter motor turns a sprocket and chain which turns a larger sprocket on the crankshaft. The large sprocket is connected to bearing on the crankshaft that can spin freely. Outside the bearing is a drum with 3 steel rollers in it that are designed to move inward and press and catch on the bearing and allow the large sprocket to turn the flywheel and sprocket when the starter is running. Once the engine goes faster than the starter, the rollers are designed to retract and detach from the starter.
When the rollers are clean, it works fine and the starter turns the stopped engine and disengages when the motor starts.
Here is the problem- if a mix of dirt and water get inside as the bike sits in a foot of muddy water, the bike will likely still start but as it runs, the dirt flies outward like a centrifuge and packs dirt into the area where the rollers are supposed to move when the rollers are in the retracted position and continued running gets rid of the water through 2 drain holes at the bottom of the casing and the dirt dries out packed in the area beside the rollers so they can't move to let the starter engage with the engine.
The 3 steel springs, 3 little pistons and 3 steel rollers all start to rust making it worse.
The only way that I could fix it was to:
1) remove left plastic step - 6 screws
2) remove shifter lever- bolt with 10mm head
3) remove left side cover - 4 screws - 8mm head
4) remove nut on crankshaft that clamps flywheel - 14 mm
5) remove flywheel - flywheel puller - special tool should be used
6) clean out the 3 rollers, springs and pistons and the cavities that they fit into, lubricate and reassemble.

Unfortunately kids will likely continue to be attracted to puddles and the problem will likely re-occur unless extra steps are taken:
Optional
7) drill 3 small 3/32"drainage holes on corner of cavities that house the 3 rollers through sheet metal cover to allow future mud to hopefully get out when spinning.
8)Use sealant to plug small drainage slot and put a small hose in the lower rear drain hole and seal it and then run the hose down and under the frame and then up high and turn the top down like a snorkel and clamp hose so the chamber can breath with pressure changes yet be less likely to fill with mud in a deep puddle and be able to be drained if it does get in water. Also one can put some corrosion resistant oil or spray inside the cavity ( Krown or similar) though the two access holes plugs and make sure they are tightened.

It is best to let children and people riding with them know to quickly pull the units out of mudholes and avoid water that gets to a point 2" below the crankshaft.

The alternative is to just put it in 4th gear every time and push start with weight on the seat until you get around to fixing it.

I hope that this is helpful.

What size flywheel puller is needed for the Kazuma Falcon 110? Or what japanese motor is this a clone of?

Thanks

 

I don't know about any flywheel puller (I've never owned a 110cc machine), but the engine is a copy of the Honda E22 engine. Clymer makes a service manual for the E22 Honda engines, and this is what most people use for servicing chinese 110cc clones.

 

I think it is the 28mm x 1.0 Flywheel Puller for that E22 motor. Finally found the info after much searching.
