high reving on my 440ex

[lakin1143]

i just put a 450r carb in my 440ex with a stage 2 hotcam and full yoshi exhaust and i had the stock main in and when i would crack on the throttle the reving wouldnt go to an idle at a normal time after i left off the gas, i put a 200 main in it and its doing the same thing, what do you think?

thats your pilot/needle position.

Sounds like the pilot is a tad lean.

Is the hotstart hole plugged?


FYI--The jetting in my stroker: Stock R 48 pilot, needle on the clip lowered 1 notch and a 200main--works great from sea level to 3000ft.

Mine does the same thing, I have the 450r and a 460 stroker, I have the needle in the middle position I am gonna try dropping it down one notch and see what happens, jetting is the most annoying thing I have ever done, my next quad will be fuel injected for sure

I have a 50 pilot and a 200 main in it right now-Ill let you know what happens..........
