The high point of this winter has been winning a blue ribbon in the Vintage Competition Class, Cycle World Readers Collection, at The Seattle International Motorcycle Show for my Norton P11 Roadracer. There were many fine vintage bikes on display.

The 1996 race season will be fourth. It looks like we may have more vintage road racers.

Fred Eaton, Old Britts, has put together a six race series called "Sounds of the Past." Quite a few new people have signed up. Many thanks to Fred Eaton for the effort and time he has put into this series. Let's get those old Nortons on the track!

Last season was a little rough for me. In June I went down at SIR in the bus stop and broke a bone in my right hand and left collar bone. It healed fast and I only missed two races. Last race of the season I busted a gear in the gear box and both shafts were bent.

I pulled the gear box out of the bike and tore it down. I went through my spares for gears and shafts and took them to Ross at Pokes Cycle for setup and reassembly.

The BSA conical rear hub I used has a real lousy rear brake , so I have fitted a Norton backing plate and shoes in the BSA hub. Hopefully this will work better.

Keith Johnson drilled my front Commando disc. It lightened it by 3/4 pound.

I'm going to have Ross check the engine over, but other than that, I'm ready to race.

Now about the bike:
