dajogejr Posted May 31, 2006 Report Share Posted May 31, 2006 Are you leaving your airbox the way it is, stock filter with the lid on? If so...you'll be around 250 or so on the mains. Middle clip on the needles. FMF pipes like a fat pilot circuit. With the airbox and lid on...you could probably be ok with stock pilots, but you might have to bump up one size (to 27.5 ) with the pilots. If you end up running the air screw .25 to .5 turns out for it to run right off the idle, get bigger pilots. Quote Link to comment Share on other sites More sharing options...
chronicwatson Posted May 31, 2006 Author Report Share Posted May 31, 2006 i think i may try a 280 do you think that will be to fat i'm around 700-900 feet and the air temp is around 60-90 f Quote Link to comment Share on other sites More sharing options...
sheefreak Posted May 31, 2006 Report Share Posted May 31, 2006 I think you will be fat at 280, especially w/ a foam filter. It won't hurt though, you can always go down from there. I thing dajogerjr is pretty close. Quote Link to comment Share on other sites More sharing options...
batoutofshell Posted May 31, 2006 Report Share Posted May 31, 2006 Same pipes as you running 280 main stock pilot, k&n lid off, proflo and outerwears, toomey needles 4th clip. Hope I can help Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 31, 2006 Report Share Posted May 31, 2006 i think i may try a 280 do you think that will be to fat i'm around 700-900 feet and the air temp is around 60-90 f You will definately be safe...that's for sure. I think you'll find cleaner running a little leaner though... Always better to start off Rich....best of luck!! Quote Link to comment Share on other sites More sharing options...
chronicwatson Posted May 31, 2006 Author Report Share Posted May 31, 2006 you think i'll be safe with a 260 Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 31, 2006 Report Share Posted May 31, 2006 I think you should spend 20 bucks in jets, get 250 to 270. Start with 260. Spend another 10 in plugs. Look at your plugs...they will tell you. 30 bucks in plugs/jets is alot cheaper than a fresh top end. No one can tell you with 100% certainty you'll be 100% safe. We're just basing it on our own experiences...and trying to give you a guideline. <Insert legal disclaimer here... > Quote Link to comment Share on other sites More sharing options...
chronicwatson Posted May 31, 2006 Author Report Share Posted May 31, 2006 well the guy i got the pipes off of lives near me and i asked him what size jets he was running and he said when he put them on he never rejetted and i was like your lucky your bike didn't pop and he told me you need a pro to jet carbs hahahahah Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted May 31, 2006 Report Share Posted May 31, 2006 (edited) well the guy i got the pipes off of lives near me and i asked him what size jets he was running and he said when he put them on he never rejetted and i was like your lucky your bike didn't pop and he told me you need a pro to jet carbs hahahahah batoutofshell is selling plugs cheap in the for sale section. Personaly with K&N filter and lid removed from airbox, all stock, I ran a 320 yet for several years and never fowled a plug I think a 310 would have been spot on. But I'm jetted for glamis and it is alot hotter here and don't know your elevation. FMF has a jetting chart on their website. Hate to see you blow up your banshee with too small of jets. I also lowered the clip on the needle (raised the needle) one notch from stock (I htink I moved it from 3rd to 4th clip but I don't remember) Edited May 31, 2006 by Justintoxicated Quote Link to comment Share on other sites More sharing options...
