I have a 250 -04 sherco and I would like to know what size pilot jet should be fitted as standard ( the carburation is a bit 'blubbery'low down in the rev range, just above idle). It has a 35 in at the moment. P.S. I live in england and not up a mountain!--- Can anyone help ?Thanks.

Sherco - 2004 - Pilot 33 - check your fuel screw should be about 3 turns out

Yep 33 is right,I use optimax or ultimate at 75 to 1 with fully synthetic. check the float level in case its miles out, check the banjo filter, treat it to a vx plug, it should be fine. jets available from MRS or Eurocarb

Thanks again fellas-Im off to spend some time and money on the Sherco.I'll keep you posted !
