well looking more for that, you might have had a 'slight' exhaust leak at about 5 o'clock in one of the pics. and by 'hot' if you mean LEAN then show us a pic of a sparkplug or the best way would be to get an air/fuel (a/f) reading from a dyno place .it does 'look' kinda lean, but mileage etc can change a 'look'. like i said the best way is to get the a/f checked.:thumbupI was curious about the build up on the seat and the "burnt" look on the gaskets. A concern with my modified exhaust and running no PC was that I'd be running hot.
