Quote from: neil1964 on 05 July, 2025, 09:10:06I presume that you know it is not wet sumping and the breather disc is moving freely?Definitely not wet sumping as I also took sump plate off to clean filter all ok. Yes breather is moving freely after I cleaned it. I have no idea why there seems to be excess crankcase pressure. Bike was going fine until I took magneto off to get a bearing changed. Put it together, set timing, starts 1st kick every time . I ended putting granville clear sealant around gasket etc and will test ride again tomorrow but concerned that there definitely seems to be excess crankcase pressure.
Oil from the breather sounds like excess crankcase pressure being part of the issue?
