Valve stem seals or valve guides.

Seals are an easy thing to try.

Valve guides need specialist engine machinist's work.

Either way you need to strip down your engine.

If you are using large quantities of oil then you may well be correct in suspecting your piston rings.
It could also be the valve stem seals which would cause the problem you describe.
If you want to fix it ,you can buy a top end refurb kit that includes the gaskets and stem seals so if you plan to do it then you may as well check your piston rings while you there..
What sort of miles has your bike done?

Buy genuine Honda stem seals. Seriously. Or Viton if you can get them....

A whisp of oil smoke on the over run is often a stem seal or valve guide. If your rings are gone you generally get smoke all thr time. Especially at high rpms.

Nothing is that simple though. You can do a compression test but you MUST take the decompressor out of the equation by setting the RH exhaust clearance to about 0.50 or more.

Hey Mototed,
It sounds like this guy is having the same problem as I had when I bought my Dommie that had been stood still for 10 yrs in Germany.

my slr was very smoky when i first got it,a tad too much oil and it would smoke like a 2stroke,i drained and refilled with the right amount rather than using the dipstick regular and it was sorted.all the best
