The cables are non-too long on Chinese bikes, so check that as well.

What I should have said in this post is that it is POSSIBLE that you have two issues with your carb woes. Too lean pilot jet AND slide not dropping instantly when you release the twist grip. It is very easy to have too much drag in the throttle cable, because the stock cable is so short. It has to be routed perfectly in order to let the spring in the top of the carb to over come friction in the cable. Avoid tight turns in that cable as much as possible. ........ARH
