Just checked the H2 as I went past it in the garage and noticed this puddle of 2-stroke oil sitting on the rear wheel.
The bike is still being refurbed and so hasn't moved for a couple of weeks.
Don't know if this is a common problem, but it's new to me.
I have worked it out, but anyone care to guess how it got there? (no prizes I'm afraid)

You had a bottle in your tailpiece?

Nope, but a good try !

Just to add, there's no oil on the floor anywhere...

You brimmed the tank and it's expanded in a warm garage and overflowed? Clutching at straws here

Overflow from the tank is routed wrong and its dripping on to the rim and running down to the btm

Getting warmer, there was seepage from the tank...

not overflow as such, but a bit of seepage

Oil tank leak onto swing arm, runs down torsion arm and drips onto rear wheel.
Bike on side stand.

spot on.
Triple gold medal goes to Nigel !
Not a spot of oil to see anywhere apart from the rear wheel... evident from wiping the underside though.
Is this common ?
