I don't know what to do, I just got a KFX and it jumped time and blew up, it ruined the head, piston, everything. So im looking to upgrade to a 440, (it already has hot cams) only to find that there is no one that sells a HD cam chain. Could I run a stock one and just change it every, 20 hours or something? How many hours would a stock one last? What you guys with 440's doing? And what about valve adjustments?

I have built a couple of KFX 440's for XC guys and they have held up excellent. They are run hard but the maintenance program is top notch. We did replace the timing chain when built and replace it when we freshen up the motor.
