I'm building my F2 and I just put all the cables on like the throttle and choke but when I turn my throttle it doesnt respond but when i unhook it i open it by hand and it snaps back...so im not sure how to fix this

 

I am just guessing here because I am a new guy to the CBRs but it sounds like you have not got the cable end at the carburetor attached, and that there is a binding in the routing of the cable.

Look closely at the way it is routed. Look for kinks or bends. Do you have it tied down with zip locks? Be careful they are not too tight.

The fact that the throttle grip returns may be because the throttle return spring is doing its job.

 

Make sure when you adjust the throttle cables, you leave just a little slack. If you have them adjusted too tight, the carbs will stick and not return correctly. Also make sure the cables are routed the correct way or the airbox and gas tank can pinch them.

 

Thanks for the advice I'll look for those things...Im new to all this I'm use to working on a Chevy not a Honda bike lol but I like it so far
