What pilot jet does everyone use on a keihn carb,its on a 2002 290 sherco and its got a 42 in it and its too rich,so i was wondering what everyone else uses because it had a 48 in it before and ive changed it and its still not right.

Thanks

std jet for a 290 is 33 with a delorto.

I run a 45 on a 250 Gasser and it's perfect. Are you sure that a 42 is too rich, for a 290 it should be waaaay too lean. I used a 50 on my 300 Pro last year. I ride between 500 - 1500 ft above sea level. You may have something else going on that makes it feel too rich.

I run a 45 in mine and it seems perfect.
