Hey Everyone, I decided it was time to do a rebuild or an engine swap on my 93 cr250. I decided to install a good used 98 cr250 motor in my 93 cr250 bike. I had no problems installing the 98 motor on the 93 frame. I installed a new oem cdi black box, new after market stator and coil. the electrical system I installed is for the 93 cr250 motor. I also installed a new keihin 39mm pwk carburator, new boyseen reeds, new air filter. I cant get her to start for nothing. acts like she wants to start, kicks back alot when tryin to kick start but will not start. with the old motor it usually started within 1 to 3 kicks. I tried disconnecting the kill switch and that didnt help. does a 98 cr250 motor need the electrical system from a 98 cr250 to make it start or will it start with the 93 cr250 electrical system? I also tried adjusting the timing which didnt help. what could cause it not to start. I dont know what else to look for.
