Brilliant! Keep it up! Im building a bike based on a Suzuki gs500 frame with a yanmar 3 cylinder diesel. Similar idea to you, ive cut the gearbox from the original engine but Im running pressurised engine oil into the box through the gearbox's original oil ways with a link pipe back to the engine sump. Test run should be in the next few weeks with any luck. Hopefully the nice weather will arrive shortly here in Scotland.
That is awesome I hadn’t seen anyone else try it I like your idea of keeping the gearbox pressure lubed didn’t even occur to me. With the 3 cylinder it’s going to fly
