jetting tips

[Fastbansh]

I had a mechanic do my jetting cause i didn't have time...he put 240 mains and stock pilots...i have dmc 916's and noss 21cc heads k&n w\vents .....it seemed to run great...raced my buddy with fmf fatties couldn't pull past i have been ridding for 12 years i'd say pretty good....it just doesn;t feel like it should...i'am at my wits end with this thing...any advice would help......

whats your elevation? Sounds little lean on the main. My brother in law has the dmc's and I have the fatty's their almost dead even with equal weight riders.

yeah that does sound a little too lean..i would try going up a few sizes on your mains

my cousin has those pipes and he runs 270 jets and it runs great he beats banshees with tommeys and fmf sst

Same opinion as the rest........ depending on your elevation, i would think that you need to go up on your mains.

my elavation is about 1000 feet above sea level....also i have reed spacers does that affect anything

They wont affect your jetting, try 270 - 280.

Your dealer put a basic jetting kit in. Most kits recommend 240 mains for pipes. Like everyone else said. Start w/ a 270 and make sure you mods the air box lid or remove it...You'll gain another 4hp.

If you are using a lid, try 280's. No lid, try 330's. Either way, run it at wot. If it boggs or stumbles at wot in 6th gear, try the next size smaller. If it doesn't bog try the next size bigger.
