I start hearing a noise like someone snapping a small limb, or some pop corn being popped or a small pebble hitting your car windshield several other ways to describe the poping. ??? It wasn't constant and did it in all gears. I never could pinpoint where it was coming from. I don't know the history of the bike and don't know if it has done it from day one of my ownership since i wear the Modular helmet and listen to music. Do you think i might have that going on with my bike????

I think I recognize the description of the noise you talking about. It happens under anything but light acceleration. I already have rockouts installed. It started after I switched to a new set of slip-on mufflers. I believe what your hearing is (spark knock) pre-ignition. I run rec-fuel ,100%gas 91 octane. I’m going to reflash the ECU or run an auto tune with my tuner. That should cure to noise.

If you have noise, give it a try at your next oil change

Chalk up another success story for Rockouts! After we put 'em in yesterday, my neighbor waited until he could get new spark plugs for a start today...and he reports that the silence from his valve train is...golden...
