    It's just a normal P8 needle jet. What do you mean by cut down? I am going to try the bottom notch on the needle and see how she runs. I have to put the motor back in first though :) there is something about Idaho and XTs, I got both my XTs from up there.

    The top shield looking thing is often cut down on the two stroke style needle jets (non bleed) when used on four strokes.

    Interesting, thanks. I couldn't get the bike to run right with the 6DH3 needle and P8 jet (I even tried the 6DH3 needle with the Q5 jet and it still wasn't running well) so I put the Q5 and the 6FJ6 back in. It runs well enough in this configuration that I will probably leave it as is at least for the rest of the summer.

    Try the P8/6DH3 again and trim the shield to 5mm. It will make a big difference.

    It's been close to two months since the last race...:cry
    Getting a little rustier than I was! Maybe that's crustier.
    Had some time to look things over and think of what I want to do next.
    After looking closer at the 15t countershaft sprocket that I took off, I noticed that there was considerable wear on the inside of the sprocket.
    Looking back at a photo that I took prior to even riding on the track (pre-swingarm incicdent), it appears that things were out of alignment then.
    I found a shop in Spokane that will de-rake the steering head and straighten the frame. Next race is a week from now, so this will have to wait.
    You can see the mis-alignment in this photo

    Tonight!!! I get to race!!!
    Took a closer look and photo of the suspect.
    Not sure if the frame/swingarm were bent on my first day on the track or "If" I just bought someone's beatup motorcycle. Going to stop by the welder's shop on the way to the track and let him have a look see.

    On man Willie!!!!! That pic of you on the stretcher is scary! Good to see you are smiling.

    But that may have dashed any thoughts I have (at 55 years old) of trying flat-track racing.

    Best wishes for a fast recovery.

    Wow ! Sorry to see you in that condition. Bikes are easy to fix, our bodies not so much.
    Hope you have a full and speedy recovery.

    So, I'm really feeling it today!!
    they had to reduce the dislocation my right shoulder.
    Looks like it took a lot of force!
