I called Motospecs few weeks ago and they no longer do the 3201 kit or the roller top .   The Newcom link doesn't;t seem to work unfortunately , might chase up pedders see what the deal is there ..   Otherwise will be following the instructions here and machining.   The roller tops used to have a washer that went between the bearing and sector shaft , you guys do that ?   From memory the roller bearings in the top cover are the same as the two lower sector shaft bearings ?
