well i bought it from the local harley dealer. would it tell me honestly the only reason i care is it needs to be tuned because its popping out the exhaust on decel and between shifts and all the tuners i've looked at need the info.

 

ok i have an update the 103 cover is just that a replacement cover. i was able to get a boreoscope and checked the piston tops for part numbers and found it is a 96 inch motor.thanks everyone for the help.
