anyone have jetting or setup tips to get better mid range out for a 09 300 xcw? it has good low range but when half or wide open throttle it seems slow. took out my buds 250 xcw on the same loop and i had to let off the throttle in areas i had to hold mine wide open. i just went to a 152 main from a 158, shop said it was too rich up top. this helped things but is still missing something. i would think holding a 300 wide open would want to throw you right of the back, the 250 seemed to hit the powerband with more power. when i bought it new it seemed to have plenty of power. now not so much. even lifting the front end in rocky technical areas seems lagging now. stock gearing, 50r 14(?)fr. AS is 1.25 out (i tried 2 out and 1.5 out) mj is 152 p is 35 3rd clip yellow pv spring(liked red but it just made it hit harder down low) fmf tc 2 muffler, stock up front.
