Default Re: Assembling Kit strugges!

2. The clutch is always engaged... I can use the pedals

3. The throttle assembly seems pretty straightforward, but there's very little movement on the handle.

Any suggestions on any of the problems? Thank you!

The instruction manuals (with the package and online) leave a lot to the imagination I find!


Your right dude that lilttle gear should turn relativly freely and is the answer to question 2 also,
if moving the clutch lever does nothing and your turning the motor over always pop the tear drop clutch cover off, remove the locking screw around the flower nut then wind the flower nut anti clockwize 1 turn. rock the bike till its free and you will see the outer clutch gear turn only. you will figure out its opperation and adjust it so when its engaged it doesnt slip and when disengaged its turns freely and you can pedal.

As for the throttle pop the top of the carb off, make sure that the throttle slid the copper thing
is in the right way it has a groove down 1 side and the bore that it sits in has a lil pin that guides it.
if its in the wrong way you wont get any twist on the throttle handle and it wont go or will be at wot when ya start it. sometimes they put it in backwards. good luck!
