Hey guys check this out. Sounds very promising.

Wow. 2 grand plus you'll need to buy 35mm carbs and filters for another $400 and you'll get about 54 hp, plus quite a bit more bottom end. At least that's what the dyno chart says. What will be really revealing is seeing this 400 kit with porting. I wouldn't be surprised to see it get to about 65 - 70 rear wheel hp once it's been swiss cheesed. LRD is listing these powervalve cylinders in their ads now, but they don't list pricing yet. These are basically the long awaited cylinders that Pro-X has been working on for several years. I would think that pretty soon everyone will be offering these bolt on kits. Hopefully pricing will come down a bit by next year (when I might be able to afford them). I also wonder about the stock crank assembly holding up and whether this kit will fit on a long rod motor... and they said the banshee was dead.... Ha! Long live 2 stroke twins!

 

Well that kills the use of the RZ350 cylinders. No more searching for those old street bikes.
Who ever has the money, will have a nice banshee.
Too bad, now when I see a guy wanting race me and I see he has those cylinders, I will say, "No Thanks".


Peace

 

Ya it is pretty expensive. But for big power gains, you gotta pay to play. And I'm sure many will. I'm sure even Raptor owners who have put some serious $$$ into their engines, would be hesitant to drag race a shee with these cylinders.

 

They better be!

 

As soon as my cylinders are dead, I get this! Incredible we had to wait so long before getting this!
