I bought an 08 WR450, about 3 weeks ago. I have done the following mods: grey wire removal exhaust baffle removal airbox snorkel removed adjustable air screw installed installed GYTR AIS removal kit (jets, needle, etc) still have AIS installed aluminum hot start knob (stripped plastic POS when i re-jetted) bark busters What other mods (somewhat inexpensive) can i do? pipe? Stock bike ran like an 80cc, now I can feel the power! So much power that 1/2 mile into my ride with the new mods that i hit a steep rock, launched myself 8 feet in the air, and crash landed! I thought I must have busted something on the bike, and to my surprise, stood it up, hit the e-button, and was off again. This time, i was a little more carefull of rocks!
