pillns Posted May 24, 2007 Report Share Posted May 24, 2007 Hi I have a 2002 290 which i bought 6 mnths ago. It has never ran 100% from day 1 so ive given it a full strip down. In the carb i have a 126 main jet and a 30 pilot jet. Are these correct for uk conditions? Also if i do need to change the jetting where is the best place to get them and are jets all the same size - i.e will jets off other bikes fit as D&K motorcycles is only up the road. many thanks Quote Link to comment Share on other sites More sharing options...
gasgasssser Posted May 24, 2007 Report Share Posted May 24, 2007 Main jet is ok.Pilot is a tad lean,should be 33.You can get spare from eurocarb,they have a web site i think I bought a 04 290 18 months ago,that never run right either.Messed about with diffrent jets etc.Eventualy took it to bike shop,turned out piston was in wrong way round.Runs sweeet now http://www.sherco.com/downloads/service/02_manual.pdf Good luck Quote Link to comment Share on other sites More sharing options...
copemech Posted May 25, 2007 Report Share Posted May 25, 2007 (edited) I would think you should notice much better low end power with a 33 pilot. If you run the main at around 120 it will rev out cleaner and quicker! 3rd groove on the needle and about 3 1/2 turns out on the mix screw(will vary).
