I have ds650 now 720 with Ronwoods high compression; valves, guids, double springs, JE piston 11:1, racing fuel heads port, and polished, Ronwoods exhaust with AC Black lable bumper, nerf, and now full skids, sitting on what was once a yellow kitt now a Black 05 look with Orange X rolling on DWT two tone beadloc Black with Orange rings. I have jeeting issues with my 185 main jet its still back fireing. I'm thinking about going to a 195, or a 200 any suggestions?
