Hi I just got my 80cc china and the clutch is so tight that it even takes force to push it in by hand. when i press the clutch lever in the clutch does not come in at all. do you have any ideas?

new it may just need breaking in. also the clutch handles that come with some of the kits are real junk and a lot of people replaced them with break levers which give you more throw. some of the kits do come with better handles though

I had that problem and on the other site they gave me a lot of grief about it. All you need to do is work it by hand several times then get a good lever the one with the kit wouldn't pull mine at all. I bought a brake lever and never looked back.

Take the sprocket cover off, and put a dab of grease where the clutch arm goes through it.... Also on the pivot that presses in on the pin. When yopu reassemble it, make sure you pull all the slack out of the cable and push all the freeplay out of the arm before you tighten the cable end. (it's easier with two sets of hands)

Run a few drops of light oil down the cable.

To worjk that clutch arm I have a post where you work the clutch arm with vice grips make it very esay to hook up the onery cable at the clutch arm.
The rest of the advice will do you good as well lube will always make things go easier.

You will be amazed how easy it is to adjust the clutch after the first time you do it. The nice thing is you can dial it in perfectly. Mine was "over engaged" from the factory....ie when the engine warmed up, my bike would start moving even with the handle fully pulled.

Indeed a nice lever makes a big difference as does taking the left engine sprocket off and greasing in the hole and greasing the pivot point. Also lube the cable and the cable exit point on that mount on the back of your engine.

PLUS make sure your cable sheath is not too long for the cable as it was on mine. I cut about 5/8" off my sheath with a Dremel cut off wheel (cable pulled back of course), relubed it, stuck it back together. Sweet!!

PS you know you have it well lubed and stuff when you can push the clutch arm with your left hand and take the cable out of the slot with your right hand.
