[QUOTE="johnmead, post: 44353, member: 776"] I am building a special using early Rapide cases with Terry Prince 92mm topend and 92mm crank w/30mm drive side mainshaft. Cams are MK5. I also have a Quaife/Sertes 5-speed and Newby 40mm beltdrive. It is going into a 2005 999S Ducati frame with a 916 single sided swingarm. Rear wheel is 5.5 inch wide. I had to offset the engine as the widest wheel that will fit with the engine centered is 4.5 inches and required a 520 chain. I just got the stock Terry Prince heads back from being on a flowbench at a local NASCAR engine builder. He said I should get 44hp/cylinder with the MK5 cams. He pointed out a couple of areas where the flow could be improved and I am going to do it and take the heads back to him for a second flowbench session. I am also running a Grosset starter and BT-H magneto set up for dual plugs w/30 degrees of advance. This gives me a short advance needed for the Grosset starter. I plan on holding down the kill switch, pushing the starter button and when the engine is up to speed, releasing the kill switch. I am not going to use the stock valve lister setup. Squish band is set at .050 in and I am using valves from Vincent Parts Germany. Valves are waisted below the buide and have thinner heads to give lower weight. Lower weight is needed because the MK5 cams peak out a 6800-7000rpms. Initiall cargs are 37mm Keihin FCRs but I also have a pair of 41mm that will need new intake manifolds before I give them a try.
