Update on the Thunderbike 904cc big bore cams is that they tested grind-A, and found that they didn't have the desired results. So they will be testing grind-B & grind-C in the next week hopefully, these have more lift, duration and different timing.

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