Newer pistons coating should evolve so no damage will happen for a small detail as no oil ;)
Its available; its called Dry Film Lubricant. Won't let you run without oil, but surely helps prevent that galling.

For the record, it is NOT Bill Benton-proof stuff though...  ;)

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis

I'm going to be sure to have my wife fabricate some engine diapers for us by next season. Got one on my top gas Kawasaki we can use as a basic example. They may not be NHRA/SFI approvable but if they contain several ounces of oil, it'll at less give you an opportunity to roll to the side of the track without completely oiling it down and will keep the slick stuff off the tire so the rider stays upright til the bike stops. I'll get this going while she's on Christmas break from her tutoring business.

What kind of fibers will she use Frank? If Bill can destroy a Carrillo........  ;)

They look good Bill. Tell Kenny we're going to put these under a load  sometime next season. I might have need of one of his lockup clutches so put him on alert.

You still got a taste in your mouth from that super eliminator record you set don't you?? Craving more?? Lol.

Oh, did Bil Baxter email your official record certificate yet?? I gave him your email information but not the mailing address for the hard copy.

Without side by side competition, you may not have pushed as hard. I was just giving you some incentives. Lol.
