But the Thunderbike cams are just for the 865 motors, I think they are pretty much the same as the standard 790 cams.
Phil just had his big bore done, finally, and he advanced his exhaust cam by one tooth. I would love to see a dyno on that.



Your probably right about TB cams. I was talking to Graeme for a while about them but he ended up saying that I would only get a little bit of extra torque down low in the rev range as their dyno chart says.....but there dyno probably includes needle changes / porting etc. that gives them the extra torque.

I too want to see what advancing the exhaust cam will do on the dyno!

TBA, Stainless extractors / drag pipes, 65mm over forward controls, Thruxton needles, 904cc, head ported, lowered 1-inch, Console removed, relocated battery box, Australia.
