[QUOTE="Matt90GT, post: 1134583, member: 30871"] Biggest problem they have is the jetting. Yamaha never got the jetting crisp on the 426s. Came close on the 02 models, but with the leak jet on the 450s things were much better! Basically get a JD jetting kit, do the BK mod and extended fuel screw installed. Also the 450 exhaust cam or Hotcams with autodecomp will make the bike much easier to live with [/QUOTE]
