Bubs sent me out the lastest greatest design and I changed it out. 4000 miles later (today) I am noticing a golding effect on the front cyclinder. I was told I had to have the Screamin Eagle EFI race tuner for these Rinehart pipe when they installed them. It was a "generic" download. Is it possible that things are off enough to make the bike run hot at the exhaust port. When we was in Sturgis going to the Kiss concert at the Glenco and llllloooonnnnggggg slow traffic my bike died just feet from where the guy was telling me to park my bike. Pretty scary to have your bike die like that. Now to see these hot spots on my pipes I am scared to ride it and damage something. anyone have similar scenario? Whats the cost of Dyno-tuning?
Without knowing what else you've modified it would be hard to say, but sounds like you're running lean. A good mechanic should be able to tune the bike to run properly without putting it on a dyno, but they make a lot more money when they do the latter.
