Well I've had the bike for a bit now got it alot more sorted out than when I first had it . I do like the bike you just cant beat the lightweight . I'm coming to terms with using the clutch alot more than I had to on my Honda 450 . So anyways I put on a new mx 31 tire for the race last nite . Its a sand track but mixed with clay . I'm finding honestly the bike has to much rear bite now and its bogging the engine a bit also I find over 4th gear jumps I can feel the rear end is out of balance you can feel it in the air like a bad wheel balance . Does anyone ever balance their tires or perhaps rotate on a spindle of sorts then possibly rotate the tire away from the heavy side for balance ? I really liked the stock bridgestone tire alot more as it allowed a bit more spin and allowed the engine to get in the powerband easier . Ps this bike is a holeshot machine In all my motos except for one I've gotten holeshot . I know in the past I had some negative things to say about this bike but I'm really starting to get it sorted out to my liking now . Ps I just love the hydraulic clutch .
