i have a 08 wr450f, took it to the dealer to install the gyrt ais kit and the merge adjustable jet and the adjustuble fuel screw, When i took it home i tried it and worked realy good until i decided to take the exhaust restrictor off from the muffler:banghead: my bike has the hikups (like if i was running out of gas) at mid throttle. what can i do? should i mess with the adjustable jet kit or the fuel screw? forgive my stupidness this is my first bike soo everything is new to me thats why i bought the adjustable merge jet kit.
