OK,
I have to break out my service manual. I know exactly whats in my motor now. When I got it first, I had no clue. It came with a PCIII serial that make the bike run like complete chit. As it stands now, it does feel like an electrical problem. I am going to install new spark plug wires, changed the plugs yesterday. The vacuum leaks sound like a possibility.
I do believe it's something very small and dumb causing this problem. I never rode the bike for awhile as I lost interest in it. But have found a new love for it on the highways. Speaking of which, on the highway it runs fantastic. TOP end she rips. and seems to have the crisp TR that I am chasing. However, low end, and idle is an issue. We were on a ride the other day, and one of my buddies on his new yammie stryker and I had a little toot. He was max'ed and I just blew by him like he was stopped. And I am not far off my "brothers" Supercharged street glide on top either. I know there is HP locked away in my bike. Once I get the low end figured out, its going to be a great ride. I know it's something stupid.
My motor has the following. ported heads (don't know by who)(that is the mystery I have with my motor, the local Harley shop said it looked to be a professional job. But, ultimately, Until I look myself, I won't know. 211 screamin eagle cams, PC III USB, pro pipe 2-1, stage 2 se intake judging from the parts on the bike. As I said earlier as well, the bike does run much better than without the PC, so I am figuring I have the tune pretty close. Dyno yes, is the best way to the 100 percent out of your bike, but I have tuned many bikes, sleds etc, none with MM fuel injection however, and I have gotten very close all the way around.
