crazypj said:If you have service manual with oil flow diagram it should be relatively simple to find oilway on/in clutch cover or crankcase to tap into. If not, you have to figure out oil flow from the castings which csan be much more difficult. RS motor has pretty long cases though so you have more surface area to help keep oil cooler, it may not be needed?
crazypj said:33mm 'flat slide, smooth bore' will flow way more than a 32 (and probably 34mm) conventional CV carb. You will probably be way better off with a 31mm or even a 29mm as even the smallest one will flow at least as much as the CV on there now. Your right about having accelerator pump, it will let engine pick up much quicker. You may need to change metering jet for it though and possibly limit pump stroke
crazypj said:Is the carb information from Mikuni site or from a retailer?I got info direct from Mikuni on the VM's, only bit I can remember off top of my head is VM32 will support 50bhp per cylinder.
If you work out various throat sizes, a 36mm has almost double the area compared to a 26mm carb with a corresponding reduction in flow velocity. May be OK for a bike that rarely sees less than 6,000rpm but would probably be pretty horrible around town
