Can anyone give me any advise as to where i can find aftermarket carburators for my 1981 XV920RH. The diaphrams are bad it is difficult to find good used ones. i would think you would use 2 seperate carbs and rig up a throttle pull as used on an RD350 here in the usa. it seems like individual K&N filters may work or possibly the stock boot. i would appreciate any advise in the carb area. thanks, bob druge coventry,ct.usa
