Hey guys the K&N jet kit i got went from 170 up to 200 main jets, and ive ran them all as i have added mods to my bike, but this weekend after more airbox mods, went up to the 200 (the biggest i got) and it was still runnin lean. So where can i order some 205's up to 220 or so.
thanks alot.
Rob.

 

is it a khein carb ? if so dennis kirk has packs that go up higher or james lucky . might even call khein . do not know if they will work if not a khein but i thought i would let you know .

 

If it's a Mikuni, maybe check with Sudco Mikuni jets

 

Its the stock carb!!!
Rob.

 

Rob, we have no idea what your bike is, you haven't mentioned it, so kind of difficult to know what your stock carb is. If you don't know if it's a Mikuni or Keihn (?sp) or some other, your owner's manual should tell you the maker and size, and you can go from there. If we knew which it was, maybe someone could be more specific with trying to give you a hand.

 

whoops, sorry guys, its a 01 DS650 w/stock carb.
thanks
Rob.

 

Rob, your carb is a Mikuni BSR42 (unless they changed from '01 to '02?)....Sudco should have some bigger jets for that carb....not sure of their prices, but I know their numbers go up a ways, some in increments of 2 and some in increments of 5, I believe....

 

Rob, you can get up to a 210 main jet from http://www.dynojet.com . I think this is the largest jet they make for the stock carb. Maybe, it's time for a bigger carb?.....

 

Done! Marky!
