[QUOTE="DualSportr, post: 17893, member: 19592"] Have you tried a smaller mainjet? It may just be too rich. XR's only should have info on jetting for different situations, although it's impossible to know how "brand X" carb will work with "brand y" exhaust system. The carb may be jetted to go with a bore kit, or some other mod and may be too rich. If it's popping thru the pipe it's probably rich (or hitting said rev limiter), if it's coughing thru the carb, it's a lean condition. PJ [/QUOTE]
