    well mine does it like when you try to rev when the clutch is in or in neutral
    It will do it more often when the bike is not at optimum operating temperature. Its probably part of the emmissions control. If you dont have to get your bike emmissions tested where you live, do the breather re-route, this should solve 99% of it;)

    You are running premium right? You're engine will run like crap on anything else, also, you might have gotten a tank of bad gas, has this lasted for more than one fill-up? Try changing your gas station... The breather re-route will help with the surging from idle-3k that is common on all of our bikes.

    Octane Booster is fine I use one that is good for up to 20 gallons at least every other tank. Just makes it stand up faster is all..

    Octane booster.. pff..
    Anyway.. I just picked up my buell 08 sx. Its getting its first (and last at like 400 bucks) dealer service at 1000 miles. I was getting "burps" through the intake a few times a ride. Maybe once every 10-20 miles. I'd burp the throttle to down shift and occasionally would pop.
    I had always gotten gas at the local 76, but the other day I picked up gas at costco (nearly a dollar cheaper) and I couldn't get it to pop at all for the last 100 miles.

    Breaking in? DDFI 3 learning.. averaging? Fuel? Just part of being a buell?
    I just know if it keeps backfiring through the intake somethings going to get broken or worn out prematurely.
