Had a '97 one. Had some clutch issues so changed the springs (early 5 spring clutch) which helped a lot. Then one day I gave it some and either the back torque limiter thingy in the clutch slipped or the wheel slipped.. something grabbed pretty firmly. Mag wheel with minimal cush probably didn't help. Anywho, engine didn't feel happy after that.. rode it some more.. maybe 50 miles. Tore into the engine and noticed the big end had sheared about 3/4 of the way around
