Mine is a 750L ok its a rat but hell soon as you dump that airbox you are in a world of hurt, mine had its airbox take away before i got it, then because of the way a new subframe was added there was no way i could get a airbox back, so i had to deal with k&n crap filters, and flat spot city, i had somebody play with it and got it to run ok but the flat spot at 4 is a knightmare hole, and one ive got to dig out off every ride 30 mph is shit, its iver to higher gear to keep out of 4 or to lower gear to keep under it. Every thing ive read about it is dont bother tuning just added a exhaust, 4° advancer, may be better filter and thats about it. Otherwise you can join me on flat spot hell... haha
