    05 250f front end question

    Tire pressure could play some roll in it to right?????
  4. I just put my dirt bike back together after its been sitting for almost a year its a 2003 with a 2001 motor with a 03 cylinder and 03 cam hahaha long story how that happened but its all i had because the other stuff got destroyed and i tryed to work it. I just started it a little while ago, but i noticed the kick starter was easy to kick i havent rode it in so long maybe im not use to it or from riding my 450 anyways i ran it and reved it a little and it ran smoother then ever!! but im thinking maybe the 2003 cam isnt right for it because of the compression i felt,will the cam be ok on a 2001 header?? and second i couldnt really ride it cuz it was late and i live downtown LOL and the chain wasnt on but i let it run for like 30-45 secs and i started to see the pipe lit up it wasnt glowing but it was were i could see it in the dark getting hot,about a inch or so of the pipe lit up by the header is this normal or should i have something to worry about??? Well i'd like to say thanks alot to everyone thats helped me out with this thing, You guys are awsome here!!! -CK
