Been running well for far too long Stu. No oil leaks and as fast as i like it. Always has a burst up to 90 mph when out. Today was a first kick start up which is not normal due to my weak legs. Next job to do is fit another front wheel i have with longer brake arms and stainless spokes but no hurry as i am going holiday soon. I might use a 20/50 now its warmer and replace my winter 10/40 synthetic i put in too make start up easier.
The thinner oil experiment went well and no extra noises. Today, one of the two orange led indicator warning lamps failed but probably a wire out in the headlight shell. Running very expensive Continental radials now and comfort over bumps is a lot better.
