Guys i bought a bone stock 05 220 that was in pretty good shape but for some normal upkeep, clean gas, air filter cleaned , trans oil changed...Found the spark plug to be my biggest problem that was keeping it from winding out, sounded like it had a rev limiter in it..After that i did the air box deal, removed the snorkel and then drilled 4 1 inch holes in the lid and installed Uni air box vents, that helped out performance alittle bit but still had that little bit of pause in the throttle right before the power really kicks in. So next i dropped the needle 1 postion" 2nd from the top" and that picked me up alittle more snap but still lacking just abit, but alot better than when i started...Next im thinking of dropping the pilot jet down 1 size, BUT im also planing on a pipe and muffler combo soon, SO do you guys think i should wait for the pipe/muffler combo before dropping the pilot jet or do you think it would be ok to do it before....
