It idles and runs fine with backfiring after about 3 seconds of hard decel from higher engine rpm. I took the bike apart to do some mods. Among the mods is a change to a sportster muffler and I will be adding a pod air filter. Sitting in my lap at this very moment is the Jetset pack that I just got with the new pilot jet as well as the main jet in sizes 150, 152.5 and 155. I've read on here were some have changed the main jet but left the stock pilot jet. Other's have changed both. I see people on here using all 3 of the main jet sizes. I've searched the forum before posting this question but I didn't seem to find a definite setup that I should start with.
Question 1- with the sportster muffler and pod filter, should I try the 150, 152.5 or 155 main jet first?
Question 2- should I keep the stock pilot jet or change out to the new one?
Question 3- shouuld I add one or more of the little washers that came with the Jetset?
Somebody please give me opinions on the best starting configuration.
Diamond Jim,
This should probably be a separate post..... the answers can be long.....
Can you start a new one.......
