Im trying to "get the bog out" Its not as bad as my 02'426 was but its there and the fuel screw helped a little. Some one on TT said the stock jetting is lean from the factory, is this true? Anyway, Im putting on the quickshot 2 to see if it helps this like it did on my 02 426. Im using the stock exhaust for now and I live at sea level here in Florida. I have some left over jets from my 02' 426..JD's Is redbeard450's AP mod applicable on a 06 YZ450F ?? Thanks people!:thumbsup: -JR

Yes its been done with varying results. I did it with a quickshot cover and love it. Try sorting throught these and see what you think..........

I've got an 07 450 and the bog was there also. I tried everything including a Boyseen Quickshot I already had, different pilot jets, main jets, leak jets, raising the needle and wiring the AC arm to the adjuster screw. No luck for me. I gave up and sent the carb to Zip-Ty racing like everyone said and I have to admit they did a great job. My throttle response isn't 2-stroke quick, but it's close. The bog is gone and my carburation is really good. I got my $100 worth. I did all the jetting changes they recommended before giving up, so what they are doing internally is making the big difference. I now run a 165 main, 48 pilot and my fuel screw about 2.5 turns out, just like they suggested.

Send your carb. You'll never get there with brass changes or a Boyseen Cover.

I feel the same way, my carb is pretty much just like yours, same jets same fuel screw setting.

also adjust some of the play, but not all of it - usually too much out of the throttle cables....this with the ZipTy will make it instantaneous response on the 06/07:thumbsup:
