|  Quest about adding after market exhaust
About to purchase a bike. Have 2 neighbors that are long time riders. 1 of those 2 neighbors and I are both car guys..... so here is my question, on a comment/debate we had about one bike I was looking at. Shouldnt the standard practice be, that if you add high flowing (and usually louder) exhaust to a stock bike, you should install the proper jet kit (if carbed) or chip (if fuel injected). My theory on this... is if you have decreased the backflow pressure, you have increase the bikes ability to breath. A bike I was looking at had Vance and Hines exhaust but no jet kit, and would backfire some upon throttle. To me, this theory would place any bike that has such aftermarket exhause into running in a LEAN state. A LEAN state in turn would have higher temperatures and eventually could lead to a hole in the piston... right? My question is am I correct in my thinking here, that you should always do the exhaust with a jetting kit, to get the mixture back in a proper state during combustion ? If someone did NOT install the jet kit, at what point ( average miles driven without a jet kit, and when in the life of a cycle- ie: one of the ones I was looking at like this only had 640 miles on it).. is there a point of damage to the motor.... Thoughts, comments ?? Am I all wet ?? Thanks in advance... maybe Ill have a bike tomorrow  |
