I am running the CR31s .They are great .Sooo easy to tune.Jet or needle changes are done in seconds.The lack of a vacuum slide means you have to ride like a race bike should be ridden .Smooth throttle inputs .You can't just wack the throttle below 7000 rpm.But when the engine is boiling and you run through. The gears at 10000 rpm plus. That is when these carbs shine.

I have a cylinder that is damaged from rust.The bike sat out in the rain before I got it. I was looking at JE Pistons. They make forged 12.5 to 1 over size pistons that bring it up to 265cc . I don't know the cost .
