jetting think i got it right????
On my 09 YFZ 450 i got a HMF performance series slip on
 , and i got the FCI intake , and from reading on the forum i think i might have the jetting right. i am at about sea level in San Diego, CA ride at Glamis and tracks in the area. main jet a 175, pilot a 48, fourth clip on the yz needle, two turns out on the fuel screw. does that sound about right? Temp's between the 80's and 90's ......... any help much apreciated.....

Ya that's pretty close, I would go smaller on the main maybe around a 168, that's a little rich for just a slip on. A 45 pilot would be better to.

I was looking on HMF's website and they recommended a 170 main and a 40 pilot for the slipon. i thought i might need to go a little more rich to take into account the more air i would be getting with the FCI intake.....oh and 2.5 turns out on fuel screw
