skyhawk 66cc clutch trouble

And keep pedaling while the engine is spinning until it finally starts. It may take 10 or 20 feet initially. You will feel some resistance to pedaling until the engine sputters to life.
 
Grubee 66cc

Is that a newer one ? slant plug. Ihave 1st. gereration grubee 66cc and i didnt have that issue, but it took 4ever to start 1st time. Now pops off 1st try all day. I give it a very good work out and it handles it.
 
just got the bike running and it runs great thanks for all the help it still needs a little fine tuning but it goes alright
 
Now squeeze in the clutch lever and use some tape or a piece of wire to hold it in all the way against the handlebar grip. .

A frugal member on here gave me an awesome tip when your clutch lever hold mechanism breaks "and it will" use 2 or 3" piece of rubber from an old bicycle tire tube works great and mine provides that extra grip when riding ,

Also I put a spare 3"chunk on my throttle grip "Ya never know when you might need more and this provides a little give when I get over zealous on the plastic throttle and it will spin or roll on the throttle instead of breaking the white plastic throttle tube if I twist to hard when trying to beat my Buddie on his bike No fair he is only 5'5" & weighs 140 lbs soaking wet & I'm almost 300 lbs @ 6'5"
 
I have question My bike will start however the clutch has been slipping quite a bit lately. My question what else can slip besides the obvious clutch pads is there or are 5there any other parts that can slip I'm looking at a SCHEMATIC AND CANT SEE Anything THAt might be slipping. Is it just the pads that can slip? Is that the only friction point that I need to be concerned with. For some reason it just feels like it could be coming from some place else. It's slipping so bad I cant even go any more yet it will start? Pardon the pun but " What gives" :)

Here is the picture I told you I'd send.


From the PM I sent.....
The clutch pad holder is bolted on the (hollow) clutch shaft (goes through the case). There is a woodruff key that keeps the clutch pad holder in place..you may of stripped the key. There is a smaller shaft that the bucking bar moves so when the clutch is disengaged the flywheel separates from the clutch pads. The small gear also has a key, of course it may also be the one stripped. And you have a key on the chain sprocket. In the meantime, I'll see if I can drag up a photo.

Personally...unless you have a pull start, I can't figure out how you can start the engine and it will not pull. If you have a broken key, it shouldn't start.

Sometimes when a woodruff key shears it can result in the affected parts acting like a one way clutch. The bits of remaining woodruff key can get cocked in the shaft grooves and bite into the shaft/ gear one way but loose all their now failing bite when the load is transferred the other way.
Sometimes this can make for a really good head scratcher!
 
Just to make everyone aware, the problem wasn't in the clutch itself. The bucking bar wore away at the ball bearing end. This can be fixed permanently by using the shank of a 5/16" drill bit ground to length.
