This is my first harley and the motor is a 69' XLCH i've been told that it is an iron head 900 can anyone tell me what to look for when buying aftermarket parts like pipes and such. I don't seem to be having any luck on figuring out what family this motor falls under. The bike is a 69' sportster with a hardtail rear. The engine and tranny are all one piece with the gear shifter on the right instead of the left. Any info on this setup and motor info you can give me will greatly be appreciated. thanks.
