I bought an 90 Exciter as a project and it was at 10 over and running 320 Main jets. Had to go 40 Over to clean up the cylinders should I go up a size or two on the mains or just watch the piston wash ? I'm at 1200' and running Benders direct injection kit which I've had good luck with in the past. Thanks !
 
Not really but that depends on how rich it was jetted before this with the mains, I would try it and see what the plugs/piston wash look like. Thats not a whole lot of bore gain.

Did ya ever get that 81 srx running? wanna sell it?
