Greetings RCV,
Thanks for the post!! Could you elaborate on some of these mods? What did you do to the ports? Increase the compression ratio-was this done with a thinner head gasket, different pistons or shaving the head and what was the c.r. of the bike that was dynoed? Also could you provide us with some info about the cams?
Thanks
Rapid Reverend
Hi Rev, The work we have been doing to ports has been carried out by one of the guys who was previously in our service dept. and before that the main engine guy for the Rizla Suzuki British Superbike team. We reckon our heads will be unlike any others out there and are keeping the actual details of the mods under our hats for the time being. I can tell you though that the std. gaskets are used.
With regard to the camshafts, the std. 865cc items are shocking, affectionatly known to us as the cement mixer/lawnmower grind - like NO overlap, totally none! . This particular prototype cam we are using is a modified std. item, we intend to produce cams from billet steel eliminating core charge and waiting for turnaround items etc.
Cheers
Graeme
