Yeah, Dog 33, I have the stock airbox w/Polaris bellmouth. What is it or better yet, how can you tell that the pilot jets are too small. Daz told me I should probably do the 42's,Jenks mentions that most riders settle with 125 to 130 mains and often with 42 pilot jets, but what is the factor up to 1/8 throttle going size up on the pilot jets? More Air passing the butterfly? Or beyond that more Fuel?...............yes, by the way next time I sit and make adjustments on bike like that ,I'm going to put a helicopter in front of it,about had a meltdown,very stupid mistake. Won't assume that one again.It got extremely warm.
