wacko2000 Posted December 13, 2007 Report Share Posted December 13, 2007 Okay Im at sea level, I had similiar mods T5s v-force reeds no lid on airbox, vented out.. I ran 310 main and stock pilot.. 240 is WAY lean, start with aleast 300, its pretty cold there might even wanna start alittle bigger and work your way down...

2ss Posted December 13, 2007 Report Share Posted December 13, 2007 ive got almost the same setup and elevation is close and in summer I run 330. as a guessyou should be at 350 for the mains. Quote Link to comment Share on other sites More sharing options...

flattrakker Posted December 13, 2007 Author Report Share Posted December 13, 2007 then ill go 310's and do a chop Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted December 13, 2007 Report Share Posted December 13, 2007 Yea 350 are way to big.. I started mine jetting at 350 when I got my motor back from Passion with a hot mx port and some other stuff.. But I ended up with a 330 or 340 dont remember.. You should be around 290-310 start with the 310 and do a plug chop... Quote Link to comment Share on other sites More sharing options...
lincster Posted December 20, 2007 Report Share Posted December 20, 2007 Start at 350 mains. I run 370 mains, 30 pilots and my bike loves it. Runs all day long and doesn't foul plugs. A lean bike runs great, just doesn't run for very long...... Quote Link to comment Share on other sites More sharing options...
rtcc Posted December 21, 2007 Report Share Posted December 21, 2007 I was actually going to start a topic about this tonight. I have run 340's in the middle of summer and I have 350's in now. It seems to be slightly lean on the very topend. As the weather gets colder I think I will go up to a 360. I need to do a chop to be sure. Now I have very very few mods but right now, everything is near perfect. I dont foul plugs and my bottom and mid range are amazing. stock pilots and dynajet needles around 4th clip (i think) I dont know if it is the older fmf gold pipes but I seriously have always had huge jets in this thing. My elevation is around 1200 ft I believe. It always seemed like they were to big but I it works? Does anyone have any thoughts to why things are so different between bikes?
