I was about to use EP90 oil in the racing twin gearbox as I always have for many years (originally on my first twin I followed Richardson and I used the same oil as engine oil). I use standard bushes in the box so I guess I dont have to worry about bush corrosion. The engine (of course) runs on R
I just wondered what the current thinking is, has anything else got an edge for racing (std box) bearing in mind the low but very hard mileage this bike will get (NB dont worry about clutches and primary contamination)
