  1. sounds like an accelerator pump to me. sometimes they get stuck. take your air intake boot off and your carb should spray a direct shot of fuel into intake valve when your crack the throttle like that.

  7. HI, going through the bike this winter. getting it ready for spring. put a new crank, bearings, piston, etc, on to my baby. was wondering how much i could shave off my cylinder head safely just to raise the compression ratio a little. i would still like to run pump gas in it as well..

    finding tdc??

    hi i just bought an 05 ktm 450sx. i was told the valves needed adjusted and i am not to sure how to find tdc on the bike. is there plug somwhere to remove? i dont not have a service manuel and cant even find one. what is the spec for the ex and intake and do i need and shim kit or are they just simple adjusting nuts and studs. thanks so much!!!!
  15. hi, i have an 05 ktm 450sx and it doesnt seem to run quite as good as i had hoped. i heard these engines were awesome, thats why i bought a ktm. when you quickly get on the gas at low rpms it hesitates and hicups and seems to have low power. but once the rpms get high enough it runs perfect... it just doesnt seem to have the power like it should right out of a corner.. i had an 02 crf450 and it didnt do that?? any sugestions?????
