Help needed to identify source of oil leak in behind ABS modulator

[pohm66]

Yesterday noticed a few drops of oil on the garage floor  so after removing all the Tupperware and degreasing the area around the oil filter, have returned tonight from riding the naked bike to see where I think the source is???

However I don't know the components etc in that area. Can you help? The source seems to be back to the left behind the ABS Modulator.

I think you will have to dig a bit deeper and get the Fuel Tank off
for a better to look to see where it;s coming from ....

Maybe leaking from the Cylinder Head joint and dripping down from there?

Here's a couple of engine Images that might help ...

So how bad is it leaking and how many miles until the next 20K mile check ?  Maybe you should just wait awhile and take care of the problem then.  After all, it's a British bike and historically have been known to leak oil a bit.   

Years ago I had an oil leak from the little oil drain plug on my 1971 Bonneville ( oil in frame ) that I couldn't get to stop with a new copper washer and some Permatex Aviation gasket sealer.  Finally I tried some RTV silicone seal ( new stuff back then ) and that did the trick.

When I did my valve clearance check & adjust on my TTSE, I re-used the camshaft cover gasket since it looked fine to me.   I did give it a thin coat of RTV before re-installing it, tho.  So far, no leaks.

Are you sure it's engine oil

It could be from the rocker cover, due to its gasket or loose screws.

Thanks for the info guys, especially you Coconut. The pics were good to see what's in behind all the extra guff.

Looks to be too many possible sources without a strip down 

The oil leak is is obviously enough to coat all the way down to the sidestand sensor after a 64k ride, so will definitely keep an eye on it.... just a few drops on the paper overnight. However the bike is due for a service in about another 1500k so will be it forward to have the mechanics have a look. This is my daily ride so having a quick turn around and a loaner is the go.

I'll post where the leak is from.

Any luck at finding where the leak is coming from or repairing the leak?

My bike had a leak from the oil pressure sending unit.  It is not easy to get to, as it's underneath the alternator.
