These pictures are from a 2003 Buell® XB9R which was converted into a race bike for CCS/ASRA. In 2004, we installed a Nallin 1169cc conversion kit with oversized valves & a port job. The compression ratio is 13.1:1 and was running with a Zipper’s 585 cam. We had an oiling problem the first season which damaged the cams, pistons, valves and guides. At that point, Nallin was unable to provide us the same pistons, and when re-working the heads installed the wrong size valves and seats. Our machinist had to make pistons to work with the heads. No problem.
After getting it running again for the 2006 racing season, a valve seat fell out of the head after a few dyno pulls while we were tuning the fuel injection. Loss of compression soon followed. This damaged both cylinders, heads & pistons.
Starting from scratch once again, we got a set of stock heads with stock valves, and with minor porting got higher flow numbers and a better curve that the Nallin heads with oversized valves (edit: different flow bench and operator.) We are currently waiting for the cylinders to be repaired or replaced. Hopefully we’ll be running in May 2006 for Autobahn.

Funny,

“of ice that is…..
This unfortunate mess happened from a couple weeks ago up near WAUSAU WI. All that was left of the 2006 DODGE pick-up (on loan from a local dealership) was the hubcap. You can see the sleeve of the driver climbing out…he got out OK as did the passenger.
Always remember:
check your ice before you ride and don’t follow too close to the plow truck!”

“While this crack doesn’t appear to be as devastating or destructive as other submissions to deathrev.com, and its occurrence didn’t cause a hair raising pile-up, it was none-the-less painful when discovered. This 1985 600cc motor, now considered “vintage”, has been through alot of racing, and still remains competitive on the lakes in ice racing. I recently replaced the cases (admittedly with “good used” ones) and updated the headwork to the 61.5 hp package at a cost of more than i would like to share. So when I pulled the clutch cover off to replace what I thought was a leaking gasket I was shocked to discover the crack - I actually went numb for a second. Our ice season is short and unpredictable, and we are in the middle of it right now (January 2006.) Luckliy, the weather this year has been brutal (i.e. too warm) for racing and most of the bigger races have been cancelled due to sketchy ice conditions. However, the Nationals (our pinnacle) have been rescheduled for the last week in February and there is a slim chance i will be able to raise the necessary $1500 from “side cash” (money unknown to the wife) to get this motor back on the track. If anyone has a set of ROTAX cases I am in the market…..ice42″
[Pictures coming soon]
I spent a couple days in Raleigh/Durham, NC and was lucky enough to have visited the Ray Price Legends of Harley Drag Racing Museum. If you ever get the chance, go. The pictures on their web site of the display cases, mostly with racing leathers in them, do not do justice to the blown up parts they also have on display. I took these two pictures with my cell phone, and they were taken through the glass of a display case, so I apologize in advance for the quality. You really have to see the pieces in person.
You would not believe the wrist pin on this one. It is bent up in half, right in the middle. Truly awesome.
They also have this one on display, a piston and fuel cylinder. Not sure what happened here. Also check out the teeth on that sprocket. Cool.
