Welcome to the site man! There are quite a few of us who ride walden and KP on here. Including me. I live in rock springs right now, about a half hour from KP, and lived in laramie for a while when I was in college and rode walden almost every weekend I lived there. Also have a ranch between cheyenne and laramie, about 50,000 acres of riding. We will have to meet up some time and do some riding, along with "Rippen" and "theshee" and "hyperlite"
As for mods I'd talk to any of those guys and figure out what a good hill setup would be.
Porting (herr jugs, FAST, K&T, LC Performance, gorr are all good porters)
Cool Head w/ 19cc domes like you said
timing plate @ +4 degrees
vforce3's with the stuffer plates, or ported stock cages with dual stage reeds, both are about the same.
lighten flywheel if you're a light guy like kiel, lol or keep it heavy if your a fatass like me.
I'd change pipes though. You will see more gains from a T5 or CPI pipe.
Bigger carbs (33 pwk's would be a good size for your setup, would give some additional top end, and better throttle response)
longer swingarm if you dont have it
aftermarket suspension will make a world of difference. Just dont go too wide if you ride walden a lot. I have +2+1's and offset rims and I have to change front tires when I go to walden, as well as shorten up my rear axle or I can't fit up any of the fun shoots. Then when I hit KP or sand mountain I widen everything back up for a nice ride.
If you haven't done it yet, do the shift star mod, and grab a billet basket when you have some extra money.
That should pretty well deplete your bank account. :biggrin:
