Rejetting for u4.4

[xc450_thumper]

I've already gone up in jets because of dasa exhaust, hotcam stage 2, k&n, and various other stuff I can't tax my brain to remember at the moment. My question is how big of a jump did you guys go up making the jump from pump gas to u4.4? This is for a 2008 trx450r. Getting the carb out is such a pain I'd really only like to have to do this once :D

You dont have to remove carb. slow jet neddle and main can be changed.

how much did you pay for that u4.4? im running the vp110 and mixing it but I was thinking about switching to the u4.4 if it wasnt too expensive.
