All the 200 models at least within the same generation basically have the same top end but the X model has higher comp ratio. I don't understand though if you have a parts bike with good engine then swap it out thats what a parts bike is for? At least you'll have a rider while you get the other engine fixed right. But maybe I misunderstood you comment?

Make sure it is 10-40 oil you put in. I had 10-30 in my x, the clutch slipped from 3/4ths throttle and up. Put some 10-40 in and now it doesn't even slip. Mine needs a new bore and piston but it seemed like it smoked less now because of the 10-40. My x is an 84 and it is almost as close to running parts you can have. Thats going to change soon hopefully :)
