Hi there I about your conversion with interest. You must be very pleased with the results. I too have a 500 with a 650 engine and gearbox fitted by a previous owner assembeled with a sports cam and exhaust running the 123 electronic ignition, not sure of the spec of the camshaft though. I was particularly interested in you big valve cylinder head. My mechanic has my engine apart at the moment as itcwas leaking oil and needs new gaskets and piston rings as well as another few bits so I was wondering if it would be worth fitting larger valves at the same time. Is it an involved job and would it be of any advantage unless also having the head skimmed and flowed? If so would it maybe be better to concentrate in upgrading the carb instead, maybe to a 30mm as it's still running the standard weber 28 imb? With you experience I'd be interested in hearing you opinions. Obviously I'm not looking for wild gains but just something that might compliment the upgraded cam and exhaust. One last thing I was wondering was if the camshaft should have any stamps on it that would help identfy it's spec.
Thanks,
Colm.
