Not much in the way of classes. I think it is separated out by motor configuration. You can do grudge matches but the trophies are based on bracket racing. It is no Planet Sand by any stretch[img]i/expressions/face-icon-small-wink.gif[/img] but a fun time nonetheless[img]i/expressions/face-icon-small-wink.gif[/img] I wouldn't drive more than 200 miles to go to this for the racing. I might drive more than that to meet people though[img]i/expressions/face-icon-small-wink.gif[/img]

What are the classes for dunefest? If it is single cyl open maybe I will come down on the juice and see how we stack up, Its very short notice for me but I might be able to get my bike down there to race. Im still waiting for parts.
As far as head porting, Ive seen my bike take down big bores with the juice with this same head on that ive had for years. Its been ported by a few different mechs. Believe me its making power.
Ron, There ARE other builders out there that can extract big power from these heads.
Ron, What motor are you running? 730 still?

I would recommend the head porting that CG performance does.Chuck at CG has done my 690 Raptor and my DS and both perform very well.My stock bore is much faster than i thought it would be for the mods that i have and i believe that the port work i had done is a big part of that.I just came in from putting my 520 chain and sprockets on and that should help me as well.I also added lighter and taller front tires for hitting the whoops on the hill at speed.I will be tweaking for some time yet to try and get closer to the big bores!!!

Head Porting???
I dropped off the head of at Moto Perfect, we spent a good hour going over the engine parts and the type of riding I do, and with the custom grind on my Cams im happy he will be porting the head to flow with them Staying with stock sized vavles, since its not a top end ripper, I went with a midrange duning setup with tons of torque for playing in those soft hills in glamis( the ones you ride in and sink about a foot or more).
as soon as I get R done, ill get her dyno'd and post specs, I wont be making the HP and top end you folks are with the bigger cams, but im guessing it will be a blast still over stock <--like a little kid waiting on X mass!!!!!
