Where vintage engineering and modern material's science meet my checkbook...
I brought heads for the R50 to Kevin Brooks who went over what he could do for them. He's been doing some really interesting stuff with the engine on his "Bonita Rapide" 1955 R50. Most of the really interesting work has been done on the heads. He's lightened the valve train by 40% by replacing the valves with custom stainless steel valves with longer, thinner stems. The keepers are now made of titanium, and the springs have been lightened to suit. The results of this are less stress on the valve train and more room for air and fuel to get into the cylinder. It also looks so nice that it's a shame to cover it up. In theory I'll not only going have a more robust engine but I'll also have a bit more power too.
Next weekend I'll be heading down again. I'll be dropping off the valve covers for cleaning and I'll also be cracking open the transmission with Kevin's help. That's the last major component to be opened up. It really needs new seals and the bearings should be inspected.
In other news, the final drive is apparently on it's way back to me now. Things are really starting to come back together! Here's what's left to do:
