I'm looking at buying a 89 motor for my 97 roller. I want to make sure this will work. So will this motor bolt right in or not? Thanks any help is appreciated.

I think the swingarm dolt is 15mm on the 89 and 17mm on your 97.

do you know what year that changed?

seems like it was '90 when the bolt changed, same year they changed the clutch. i might be wrong though

my opologies, it was '89-'01 that used larger swinger bolt

Well I have an'89 motor in my '95 cr500 chassis and it all bolted up good. I'm almost 100% pos it is 88 and under that use the smaller swingarm bolt.

Thanks for the answer boys this will make number four. I just can't get enough of these beasts.

Well it sounds like it will work then

I got a 1989 motor and the swingarm bolt from a 1999 CR 250 fits perfectly for my AF conversion. Of course many people use newer motors for the Gen 1 AFs so this means the swing arm bolt in the 1989 is the same as the newer years. I bet it will bolt right into the frame no problem.
