I have a 2009 Harley Ultra Classic, stage 1 kit with Screaming Eagle Super Tuner and Bassani 2 into 1 exhaust. (the bike has a fly by wire throttle.)
The problem is that there is a very noticeable and annoying flat spot in the throttle under 2000 rpm.
The local dealership's service manager said there wasn't anything that he couldn't straighten out on the dyno.
He was wrong... when I got it back it seemed to have actually gotten worse and the service manager said that it was because the Bassani is too high performance and isn't creating enough back pressure.
I have also heard from another HD mechanic that it's the fly by wire set up, it's a common complaint due to the throttle positioning sensor and can only be corrected by using an add-on part that Kuryakin sells.
Can you offer any insight?
