Hey guys,
Well, bought a 91 Cr250 pretty cheap runs but needs alot of TLC.
I know it's an old bike and I don't want to make it new but just enough so its fairly tight and reliable.
Torn it apart last night, found a few major things to be fixed.
First, swingarm has a few cracks where the needle bearings and bushings are(probably could be welded but would perfer to replace), due to lack of maintenace. Now, is there any way that a 92+ swingarm can be fitted, (90 91) are rare!!
Next question, Tried to find a marking on piston for bore size but couldn't find one. I mesured the piston with a digital caliper Found a reading of 2,65 in or approx 67.3mm.
Can a 91 be bored? I checked wisco site and seemed to have found them saying it's nickel coated. Is that possible?
Cyl is in good shape no stuffs or markings, unless it's deformed I'll probably just give it a fine honing.
Thanks,
Mike
