08 yz450 tips

[jrlastofthebreed]

My main jet is a 187 (stock is 145) and my pilot is up one size from stock. I think stock is a 45 so i have a 47? My engine has a high compression piston and a stage 2 hot cam, KW valves, FMF bomb exhaust and muffler. Makes great power but is loud and vibrates kinda bad. Ohh and its a gas hog!

Ran a 07 yz 450 for 2 years . Jd needle , and intake. If in deep powder just make a cheapo cover around carb for deep snow, it wont run a light . I had put a capacitor and rewound stator and it still only had like 7 watts for a light. The aftermarket stator for them if still available are not reliable.
