what carb to get

That's the same carburetor I'm running. I've found the bottom end of the throttle rich but the top end of the throttle a screamer.

The cable is perfect. I had put a tors eliminator on my stock carb and was fearful that the cable might not work with the OKO carb but it was a great match.

You'll be pleased with it once you get the jetting dialed in.
 
you will pick up some top end in theory with the 34 or 35mm however the oko is VERY resonably priced and would not be too small unless your dragracing and want to squeez all u can out of the topend. bigger isnt always better..

thats what she said..
