Somebody please give me some tips on main jet and pilot jet and pilot settings for my 2002 YZ426... it has very poor mid-range. I live in Orange County, California, if this helps any... my 2000 YZ426's mid-range ran excellent, now I don't know what's up. Pilot jet is stock, pilot screw settings is 1 1/2 and main jet setting is up from 162 to 165, tends to run better with 165, but tstill not where I'd like it. Love some help if anyone has ran into this or can solve. Thanks.
