I will probably never do this with the Darmah again, but it was more fun than you can imagine! The thought of dropping it is unimaginable, and kept me from any serious lean angles. Still, I tore up the Metzlers, passed a lot of slower riders on MUCH faster bikes, and ended the day with an ear to ear...

TRACK DAY!!!

My dream came true, and I had a chance to tack the Darmah out on the track and flog it yesterday :shock:
It took a few sessions to get the tire pressures figured out, but after that she went quite well.

Geoff, Thanks for the kind words of encouragement! I think I figured out the picture posting thing again.

The MBP "bulletproof" crank is pretty, but the fine work is not as apparent to the eye. Guy has the rods machined to accept a Stainless insert on the big end, and then uses a heavy duty bearing and a rod pin of his own design. I have heard of several vintage racers with more than 8 seasons...
