thanks Jim for the info on rear removal,. removed front , and rear , installed new ECU and will change reg. -rec. if needed., tomorrow will try to start it,. I found the reg. -rec., plug is very bad, wires in back of plug was shorting out, got wet often,. the first owners kept it outside,. never rode it , and dropped it when they tried to ride it, total nerds !!! smart people with no no-how
