hey Slomas, a bit off the subject but after looking at your forks I have a question. To cure the high speed wabbles (head shake) do you pull your forks up like you have there, or do you go the other way? I have my forks sticking up out of the triples I would say .040-.080 thousands. I get the wabbles occasionally.
I ask this beacause I have a new mission in life after coming back from the dunes this past weekend. There were some real fast drag banshee's running on a flat say 200 yard sand strip with a 100 yard shut down. I ran some of them with the old 500 (stock head and port, v-force reeds, bored PJ carb, PC pipe) had to cheat a little on the start to get going even with them but I was only (here's the funny part either way you look at it) getting beat by 5-7 bike lengths. These were alky burning, overriden tranny, high HP drag frame bikes. I could run them down to a fairly respectable bike length loss. This has my wheels turning now. This is why I was asking about swingarm length and how they launch a couple posts ago. I think a nice little drag ported, alky burning CR 500 with about a 8 over swingarm and a 12 paddle could do quite well againist these things. The longer the run the better. This is going to be some high speed runs, hence the question on head shake. Do the aluminum frame bikes have this problem compared to the steel frame versions or is it a matter of fork position in the triples?
My forks are that high because my bike is a hillclimber w/ an extended swingarm. Raising them up helps keep the front end down when running shorter.
On a regular bike, the higher the forks, the twitchier the bike.
Go fast sand drags on a stock length bike, I'd lower the forks about flush and try it out.

my machine did the death wobble at gecko road in front of the ranger station. 5th gear wide open racing some goons on 4pokes. by some miracle i didnt go down like a sack of potatoes. ill think twice before doing that again

Yeah put the forks flush with the top clamp.
Also set the sag to 100mm-110mm. Start at 105mm.
You'll give up some cornering ability, but who needs cornering in a straight line.
I have notice a little head shack on my AF however the sag is somewhere between 90-95mm for MX tracks.
