Hi, just bought a 2011 48 with V & H Short Shots, Screaming Eagle Heavy Breather & Power Commander

When I first ride the bike in the early cold morning (5am) I will be maintaining a steady speed and then it suddenly goes ''gluggy' and drops power/speed. I have to change down a gear and get the revs up again and off it goes.

Any ideas?

Spence

Cheers guys
