destry is supposed to let me know if that clutch arm is a piece that can be purchased. he said he thinks that it was an item from the MC department of the team but he's not sure. i'll let you know when he tells me.

greencannon:
Tom are you sure it's not adjustable ? The pic is a little fuzzy, but it looks like a pinch type of setup.
 Looks like a slot in the billet and a hole drilled for a bolt to tighten and pinch around the shaft.  Other wise what would be the purpose ? just to look trick or save a few ounces in weight.

2-Stroke Tom:
Greencannon,
The purpose of the billet extended clutch arm was to lengthen the arm by 10mm so that there is more leverage when pulling the clutch in. It's a pinch bolt type set up but for some reason Team Green found that 10mm was optimal. I'm almost positive that it's not adjustable, it's a solid billet piece with a slit in it. I inquired about getting one of these from Team Green (there only a few miles from my house) when I bought one of their 2004 KX500s. I had no luck, but I think Destry's bike was the only one set up with this that I saw. Mine was was missing the infamous removable clutch cover and this billet clutch arm. The bike I have is the same set up as Destry's shown in the picture with the engine done by Varner, suspension by ACME.

With respect to the needle, Polar-Bus is right on target, optimum power wasn't the top priority for the Team Green KX500s. They had to be extremely reliable to win so many titles. These bikes were mildly ported, always had fresh reeds (I was told they ran stock reeds and they replaced them often), new plugs, fresh top ends, etc. Not much more needs to be done if you can hold a KX500 wide open for a prolonged period of time.

SweetTea:
On a side note, what does he use to clean that bike up to looking brand new, or is it brand new, lol! 

Sorry, I just had to post to get my 10th post, I was hoping I could edit my profile after 10 post to change the time, its annoying me, hehe.

greencannon:
Tom , maybe we misunderstand each other, when i say adjustable I mean able to position the arm on the rod so it pulls the slack out of the clutch cable, by loosening the pinch and reposition.
 I do see what you mean about the longer arm having more leverage.  either way very cool.
