DIRTBIKEZ Posted March 15, 2004 Report Share Posted March 15, 2004 Never really had the chance to finish rejetting for the new K&N w/ Noss adapter but now I have a set of FMF SSTs w/ silencers on the way. Right now the snorkle is removed with 260 mains, stock pilots, air screws 1.5 turns out. Elevation here is sea level, 40-60*F, 40:1 premix. Like I said, just looking for a starting point. Thanks.

sredish Posted March 15, 2004 Report Share Posted March 15, 2004 Sounds a little lean to me. Try 300 with a 27.5 pilot and the needle in the 4th clip from the top. As always, a plug check is really the only way to tell. Put in the jets I mentioned and then check the plugs, that will give you a good starting point.

nboost Posted March 16, 2004 Report Share Posted March 16, 2004 I have a 2004 that I just put on sst's/ titainium silencers, k&n with adaptor plate with lid removed. I put in 300 and raised the needle 1 "4 from blunt end" and it had a real bad bogg on the bottom end. I put the needle back to stock location and put in 30 pilots. All seems to be good now. I still need to run and check the plugs. I am in OKC don't know what the elevation is here. I went to little sahara last weekend and it ran pretty good.

DIRTBIKEZ Posted April 2, 2004 Author Report Share Posted April 2, 2004 Ok, started with 300 mains and stock pilots. Lifted the needle one notch, (4th front blunt end). Air screws 1-3 turns out and it seems to be idling higher than normal. Tors are removed and idle screws have been installed. Didnt have this problem until the pipes were put on. Any ideas? **Idle speed is about 2500RPM, 1000 or so too high. Quote Link to comment Share on other sites More sharing options...

Any ideas? **Idle speed is about 2500RPM, 1000 or so too high. If you cant lower the idle with the idle screws then its probably because the stock pilots typically wont work on FMF's you need to go to at least the 27.5 or most people get the best results with #30's on FMF's which is what is recommended by FMF for all their pipes anyway. The idle is probably too high because it's really lean. With the 27.5's you should be about 1 turn out and with 30's you should be 2 - 2.5 out.

DIRTBIKEZ Posted April 2, 2004 Author Report Share Posted April 2, 2004 Thanks Ducman, I will give that a try . Quote Link to comment Share on other sites More sharing options...
Banchetta Posted April 3, 2004 Report Share Posted April 3, 2004 .............Idle is too high because its lean???......Leanness doesn't cause a high idle...Your slides aren't dropping all the way and something is holding them up. Make sure you have slack in the throttle cable by the handlebars, and the idle screws are not holding them up...Putting a larger pilot to slow down the idle will only make it run richer than it wants to be, like pulling the choke, why would you want to......
