Cam failure, major bummer
Scatter,
Dean just called, the axle with the hubs, sprocket and brake disc weighed in just a hair under 13 lbs. It would be lighter but mine is 1" wider than stock for duning purposes. If it was a 24" axle like a lot of thes aluminum ones, it might be down around 11 lbs. If you want one for racing the aluminum one is probably better, if you need it to be wide so you can dune aggressively, this might be the setup. They are still in R&D and have the major bugs worked out but they still aren't pushing these things until they know they have them right. I'm just willing to take the risk.

Sorry to hear this Scatter. If anything, lighten the crank and back cut them gears while your in there. Hope all works out well for ya.
And by the way, I know were you could pick up some ponies while spraying. I'll give you a clue: You broke one! [img]i/expressions/face-icon-small-wink.gif[/img]

Cam failure, major bummer
Sorry it took me a while to reply. I called KMS and he wants the head back. Where it broke doesnt make sense, He thinks that maybe Web will warranty the cam. I will have the motor out this weekend and send the lower end off to CG performance to split the cases and clean everything up and check it out to make sure everything is groovy. I was considering having a stroker put in while it was apart and replace the jug and go to an 800. Its a considerable cost to do that to this bike when Im going to be building a full on drag bike this year. I think what Im going to do is put it back together as it was and install an axle kit and change the cams. Which brings up the question that was hotley discuss in another thread. If I go to the HPR4 Nitrous cams am I going to have to get the head re-ported to match the cams. I have 1mm oversize valves so am I going to have to change them too? Man I hate startin from scratch. Lightening the crank sound like a good idea so does back cutting the tranny anyone know about what that would cost?
Hey Jed, are you still running the stock size valves with the HPR5 cams, just curious.

The good news is he split the cases and the bottom end looked good.
I'ld think real hard before you go and stoke the engine. That's a lot of extra money and if you don't need the power a lot of money to be spent on a few extra ponies that won't help you out that much.

I don't know which one it is, I gave the other one to the Punisher.
