Use a good kwolity synthetic oil and don`t use additaves (see above).
However, many moons ago I put slick 50 into my diesel engined metal box and it made an extra ordinary difference to the running of the engine, made it rev better and was very smooth but don`t forget that its a low reving thumper, not a high performance "V" twin.
