Installing a 100 kit

[billyhayes]

I had 80 cc kit and had no problems. I upgraded to the 100 kit and keep burning pistons. I have a lot of spark rattle and running extremely hot. I've changed the cam chain and rejetted the carburetor. Anyone had similar experience who can offer suggestions? :thanks:

Sounds like you are running very lean. Do a plug-chop.

I got a 100cc bbk off ebay and had the same results! That kit was $56 and free shipping from a place in, I think Michigan. They said I did somthing wrong when installing it so wouldn't honor any warranty. I have since picked up an 80cc bbk locally here in central Fl. and had no more trouble.
