Recently bought two VF1000F’s .One an '84 & the other an '85. Now the one engine is in need of a lower crank case. My local, friendly chop-shop only has 1000R cases. Will they work? Is the 1000F top-half compatible with the 1000R lower case?
Crankcase halves are matched at the factory,it’s not a good idea to try and mix them.
It is possible to use R cases with F internals all the drilling’s are there for cam chain slippers and the like,only the bolt holes under the water pipes need blanking off.
