I have a 2005 450, stock engine, no cam mod, gytr exhaust, no lid on the box.

Jetting
168
48
2.25 turns
sea level

runs great under load, but after it warms up (which it cranks with no choke at all and idles great for 10 min or so) I have to keep increasing the idle speed until its way too high. Also it will shut down when the clutch is pulled in to coast after getting on it. I ordered a new 48 and 45 pilot to try out.

Just wondering what you guys think.

Jetting looks pretty close, have you checked the valves to see if they are in spec?
