Well it\'s been a while since I\'ve been on the board. I have one of the
clones (a SUNL Adventure 150cc 2005). I went to get gas, filled it up,
and then it wouldn\'t turn over Luckily I keep my tools in my helmet
cubby, so I pulled it off to the side of the lot and took a look.
Here\'s what I found, the starter motor was spinning fine, the gear
inside which it meshes with spun FREELY, no resistance what so ever.
So now what? Did another gear (or teeth) break off inside? What does
that gear engage? OH and the kick start is broken off (THAT was MY
fault for sure, from a previous problem) so I can\'t really check to see
if the bike will start that way either. Any ideas as to what parts I
should check?

Replacing the starter clutch involves removing the belt cover, belt,
and the intire variator drive pully. The clutch consists of three
solid rollers that ramp down on a cam shape to lock in one direction
but spin freely in another, similar to a sprague clutch. The whole
assembly spins freely and is guided by a thin needle bearing. http:// www.partsforscooters .com/164-15
The problem he describes sounds like the clutch. I was able to repair
mine by replacing just the worn rollers.

The starter motor and starter clutch can usually be changed without

require opening the engine case; I don\'t think the clutch does

From what I learn in your response, it does sound like that is the

problem, that gear is just free spinning in there, at the gas
stationn when I was cheching it before, I pulled out the starter and
spun the gear with my finger very, very easily, which I knew would
happen because I could hear when I pushed the starter, just a
wirrrrrrr, like the motor spinning with nothing happening. Why would
the clutch just conk out like that, I didn\'t have any problems with
it, and then poof!
The kick starter was a matter of stupidity, I had the transmission
cover off and wanted to make sure the parts were meshing right and
everything spun and whatnot, so I stuck the shaft of the kick start
into its mount, but without the support of the other side (the tranny
cover) it broke the cast mount and the bushing, so I screwed that up
pretty good.

Heh, I tried that, and didn\'t realize I never tried to spin it the
other way, I can turn the piston when spinning it that direction, YAY!
That\'s a good sign. Since my car was in the shop yesterday, I asked
my mechanic/friend/ geocaching buddy/motorcyclist his opinion, he
thought of a new answer: bendix isn\'t popping out, he told me to try
and clean and regrease it, then try starting it. The conclusion I
thought of (it was far out there, and by no means right) was that
somehow the polarity got crossed and it was spinning the wrong
direction. I\'m also working on fixing the kick starter (which one
will be fixed first, dun dun DUN!!!) by using a mountain of steel
epoxy, rather than replacing the entire transmission plate, we\'ll see
how that goes.
