That brings to mind one of our members, last year I think(?), when he realized his bike's battery was overly low yet a short run to see his g/f, anyway the bike was home not running & his bother or relative helped get the bike started only it backfired & blast was that great that it blasted the wondow of a nieghbor. I think later on he found several nuts & bolts missing from a bracket around the can.
I would get the carb tuned to the loud straight pipe. It can be done for I did a lot of flat tracking of HD & Indian to Brit bikes with straight pipes yet for yrs I have seen HD/Cruisers riders coming to the stop signs to gun their engine engines (which I never do when riding a sportbike or even more regular bikes), & then they will fart & bang to sound so sick.
