my 2056 Type IV leaks a couple of 3-4" oil spots every time I drive it, which is a couple days a week lately. the drain plug has a new copper washer, and the taco plate has new rubber and paper gaskets with gasket sealant.
I think the leak is from the case halves. Mobil1 10W-30. Would a higher weight oil make a difference? Man, I hate oil leaks! |

can a 60's era british motorcycle be made leak free? the answer is, I am afraid, no. too many mating surfaces, paper gaskets, heat cycling, they will all leak eventually. it can be mitigated with sealing compounds, proper lubricants and careful assembly, but its going to leak. 10-30 synthetic is too thin, 20-50 dino will slow the drip and dissipate heat better. originally designed to run straight 30wt or 50 wt depending on climate.
