Default Clutch won't engage

I've been reading on this site for quite awhile and have done a lot of research on my problem but I'm not confident that I have found my answer. I get pretty nervous when it comes to tearing into the engine guts in fear I won't be able to get it put back together.

My bike is pretty new, I was able to ride it for maybe 5 hours total before it stopped firing up. I've had a lot of minor problems but the one thing I can not figure out is getting the clutch to engage.

With the bike on a stand I can freely spin the drive chain with the clutch lever engage or disengaged.
When the bike was first assembled it was almost impossible to pedal it with the clutch lever engaged but now it doesn't matter what position it's in, the drive wheel spins freely.

Try removing the cable from the clutch actuator arm. If the clutch engages then your cable is too tight. If it doesn't then you have clutch pad or spring tension issues. Check Norm's threads on clutch repairs and tear down procedures. http://motorbicycling.com/f39/motor-...lutch-301.html

just post a few more times, without links, then they know you're not a robot. which is funny, because a robot would know how to make it's clutch work. and it's an automated system you're dealing with that won't let you post links yet, so it's the pot calling the kettle black...

don't give up. someone here can help you.

I almost didn't bother with this forum for the same reason aturner. Good luck with your problem though. You could try removing your clutch cover (right hand side tear drop looking mofo) undo the little locking screw and then rotate the flower nut clockwise a 1/4 turn. With you clutch cover off just keep mucking around with it until it feels right.

Yeah it was frustrating to have typed it all out and then post it and get what I got. Basically I was referring to a link that I found on this site that explains how to tighten the clutch. I was just seeing if somebody could confirm that what I linked to would be the right thing to do.
Sure appreciate you guys pitchin in

I'll try one more time and see if I can't get it yet.
This is the thread I was referring to and was going to attempt this procedure first.

I've read about the flower nut and I'm not sure what that is. Can anybody show me a picture of the locking screw and the flower nut?

So I got the clutch cover pulled off and when it came off this dude fell out on the ground.



It's obvious that it is suppose to be threaded on to the clutch assembly but I'm not sure how it's suppose to go. Is this the flower nut? If it is, it was completely unthreaded from where it was originally attached.

Now that I have it disassembled I'm having an extremely difficult time getting the cover back on because the spring is pushing out on the round plate that has the three holes in it. Any tips for this?

I think I got it. Sorry for all the multiple posts here.

After referring to this
http://motorbicycling.com/86495-post2.html

I realized that the flower nut is suppose to be on the outside of the plate. Since it just fell out I had no direct reference to the way it was suppose to go. Thank God for that awesome animated diagram.

So I got it pretty tight and the clutch now engages and disengages properly or close to it!!!
I was really worried about this problem.

I just have to get my new intake ordered tomorrow and get some new gaskets and I should be back on the road.

Thanks for the help
Adam
