Left hand strip
For best part of a week I've been monitoring the left side oil leak. I cleaned the case and then put bits of tissue in the cutch housing and various screws. On inspection the gasket edge was wet, but not the clutch, so I'm assuming there is a leak. NLM say this is rare on an unsplit engine and oil here is usually from the clutch. However, I think this engine might have been apart before.
Removal of the left engine case was straightforward except that the gear lever/cross over had to be removed too. There were no seized screws, which is miraculous.
The gasket faces look sound but are covered with dried up sealant. All of this will need to be cleaned off. The cam shaft oil seal is damaged and will need replacement. The clutch plates are slightly moist with oil so there is a slight leak into the clutch. I found that the 'spacer sleeve' on the splined drive shaft was free on the inner shaft. It is supposed to be sealed with Hylomar. NLM suggest that this, as well as sealing the spline with silicone can make an oil leak if the seals look fine, which they do. The kick start gers look in acceptable condition, some wear but no missing teeth or anything.
