Need Help Hi, I've got a 1988 YZ250 that has just had a motor rebuild done. New rod, piston, gaskets, ect. The bike will start up without the expansion chamber installed on it and it sounds ok other than being loud, once I put the pipe on it, it just kicks and kicks over but doesn't try to fire. I tried to blow air through the pipe and it seems like it has flow. is there anything else that could be going on that i'm missing? If you need any other info let me know, but I need some help guys.
Thanks everybody. |
