« on: March 25, 2010, 01:59:28 PM »
I just installed a 70cc piston kit on my 2007 super 9. I havent had the chance to ride it trying to find some exhuast bolts but I will keep you all posted on how it does. I started it and it sound beefy.I will put up pictures of the kit once I get them downloaded off my camera

The first place to look would be the carb. Once it starts, have you adjusted the idle circuit? It should need about 3/4-1 full turn richer. I would also try raising your carb. needle to the highest position. The jug kit will need to be re-jetted but these tips may help confirm that. Don't run it lean cause it WILL burn the piston. Try these 2 things, and either open the jet manually, or get a few up sized jets, and it will come together. Also do you have any idea of the clearance between the piston top, and the cyl. head?

I dont know the clearance of the piston. I have tried adjusting the carb and it doesnt seem to make a difference but i will try again. I thought of ordering a jet kit or bigger card for it. other than that it went together well took off like a bat out of hell till it bogged down and died on me.

It does sound lean. Have you seen sidthesloth's posts? Same condition you described! He has put a larger carb because his kit needed one, and your kit does need a larger main. 2-5 sizes bigger will do. I'm surprised they don't add a jet kit w/ a cly assem.

Yeah I think its a lean condition. I am looking at a bigger carb. It would be nice if they had a jet kit in the cyl kit. good news is my Boss came in the mail today so its time to take apart the clucth to change it. thanks again for the advice and I will keep you posted
