Why not just go with the HPD race port with the new ATV8 pipe....like the Polaris engineers who've ridden my quad said "wow, that pipe works" That's complements to HPD.

Or you could go with the 416 powervalve kit from HPD. I've seen the dyno charts they've done on it. SCARY!

 

With the difference being very little between the 2 head designs, I'm sure Rick could do it. I would love to have the 416kit, but alcohol will make the same power, amd I bought my 40mm lectron in great used shape for $100. Hard to beat that deal, and I dont have to spend $2500.If I was in Ronnie's position, I would bore it to the next size and move on. Just my .02. Bubba

 

Dyno charts are great.....reliability of cylinders is another thing. I've seen the power-valved bike in action. Great snort, just not too sure if it's all ironed out yet. Besides, the Predators coming, the Predators coming...I really have a hard time sleeping when that gets into my brain.
