jetting question

[ohsolow69]

ive got an '02 400ex with a wiseco 11:1 piston stage 2 hotcam and just got a full hmf pipe. i got the jet kit and called hmf. they said 175 main, stock pilot and the fuel screw 2 and a half out. however somthing isnt right, low rpm's it cuts out and bogs out, what do u guys think i should do for jetting? thankyou

Put in a 42 pilot

i would say it seems a lil high main but i,m not 2 sure

nah 42 isn't to big. I have a stage 2 fmf jet kit. and at the very least the pilot is a 42. I wana say a 45 but I ran a 42 pilot? and 170 main with my stock 400 and it ran great and with my 440 11:1 its ran awsome

lol......dude....look at my sig. Depending on where you live, temp etc...it may be diff....but I live in Ohio, so nothing crazy, but all that is done to mine is EHS lid, Uni filter, And HMF full system. I am jetted at 175 main, and a 48 pilot, with the screw 3 1/2 out. This baby runns like a dream! Tons of power with no hesitations!

I would say that with stage 2 cam, you may want to atleast try a 182 or 180 main first, see how it acts, if it boggs on main circuit, drop it down. Don't be afraid to give that baby the fuel.....running rich for a little while till you get it all tuned in perfect....is WAY better than running too lean for a while till you get it tuned in right.....lol

You need bigger pilot and main. Like leasure said fatter is better in this case but be patient or you could have disasterous results. I'm ten minutes from NY border and my pilot is richer than yours and my 400 is only stage 1. ;)
