If I were to change the sprocket, grind down (what I assume is) the opening to the header, but not change the muffler or the o-ring chain, would I get a significant performance boost? If so, at what cost? Fuel economy? Increased engine strain? Are there other negative side effects? I don't have the money for a slip-on right now, so these lower cost mods have appeal to me. I just don't want to screw up my bike in the process.
I do NOT want to derail this thread, so please only reply to my questions if you have actually performed the mods I am thinking of doing. Thanks in advance!
