Carpenter has a nice "head job" for that bike.

Yup, Bob will be getting my head shortly. Not just for porting, but also he's developed shim-under-bucket tappets for the R3 to replace the stock shim-over-bucket units. I was able to turn 7800 RPM with stock pistons, rods, and tappets, but that's as far as I trust the Triumph internals. I don't want to be the guy that spits a shim somewhere over 8000 Rs! IMO, if you want to take this big bitch to 9K, you better have the right internals.
