Both nc30 and 35 use the same size valves (same part numbers), and the cams have the same valve lift (inlet + 7.7 mm, exhaust 7.2mm as per pic).Neosophist wrote:The valves and cams are slightly different, i think the RVF are 1mm bigger and the overlap duration is slightly different as well as the opening (as seen in the diragram above)
There were 'evolutionary' changes to the rvf engine which make it more efficient, and according to most tuners capable of higher peak power in highly tuned form (not your average street or track engine). The rvf ports were reduced in diameter, cam duration was increased, more effcient bearings specced etc. Most of this will make little difference on a lightly modified engine though.
The nc30 electrical system will fit the rvf engine if you transfer everything over, but by the time you've tracked down all parts (loom, pickups, cdi, tacho etc) it might have been cheaper (and easier) to get hold of an rvf loom.
The rvf electrical system is superior in my opinion: loom and cdi is better constructed, more durable and probably more reliable over the long term (the wires don't feel to be as fragile as the wires in the nc30 loom?).
