So as to not bore everyone with the details of my maintenance program, set up, or the quality of the equipment, I'll just say that none of those is the problem. In fact, I've never had any problems with the chain. But, as a result of repeatedly getting airborne, I have had all the teeth ripped off a brand new sprocket by a DRZ2 chain w/rivet link, that was immaculately cleaned, lubricated, and properly adjusted.
I couldn’t agree more that the problem was how I was using it… I shouldn’t have been hitting the double jump on the exit of 4.
I don't question those that say the current engine/driveline package is working fine for their tracks and conditions. On my home track with typical conditions, i.e., holes, ruts, jumps, etc, I expect engine and driveline failures to be common... and they are.
Chain & sprockets = go-kart, quick change= race car
All dirt track do the woopty doo's things ever once in a while, some more than others. These things are not designed to do motor cross, If I wasn't so darned dumb and had access to "cad pro", I would plot my pick up points and see what movement the rear axle does under bounce and rebound, and design accordingly. The best way to keep the chain on is the old wishbone a la Henchcraft with the front pivot being at the front center of the front sprocket . However This is not the best point for turning the car and traction out of the turns, so we compromise.
I would look at maybe the Honda odyssey deal with independent suspension and lots of travel, and or go out and hire somebody that knows how to "farm" a dirt track.
Some dirt track operators really do take pride in a well maintained track, but that is one heck of a lot work, and I guess some of them want a life away from the track.
Dirt tracks are better for the drivers, Paved tracks or better for the promoter.
I would rather be racing than shooting at bulls.
