so I just did my first build of hundred cc motorized bike conversion kit and I did about 22 heat cycles to make sure the motor was completely broken into and I am just now starting to go full throttle but my friends are going way faster than me and I am stuck down at 25 mph I don’t know what to do and I’m worried that one of the cylinder rings didn’t set does anyone know how to fix this or know the problem thanks

I thought you meant the needle on my choke im not sure how to find the c clip and where it is
Its at the end of the throttle cable that fits inside the barrel slide that then is inserted into the carburetor...You would have had to put that altogether yourself....I have not got a clue what you meant by "needle on my choke" since that is merely an up and down lever with nothing to adjust.

So unscrew the top of the carburetor, pull the barrel slide out, and tell us what slot the C clip is in so we can help you with the proper carburetor adjustment before you put it back together.
