Hi all, I just put Rinehart 3.5" slip ons on, waiting for my V and H fuel pak to come in, looking at buying the stage 1 screaming eagle breather kit next week or so. Will I see performance gains? Really not tryin to squeeze all I can out of it, but it would be nice to see some gains. Also a quick question, when moving my bike around like in and out of the garage, letting the clutch slip slighty while givin no gas, it will lug a little bit and shake like something awful. Im 6'4" 340lbs., so I figurin its just lugging to much?
