it's not leaking???

In the 15 years I've been riding a 1970 triumph it has ALWAYS leaked... fix one and another one pops up.

beautiful bike though,

Though I've never seen a repainted tank that looks anywhere near as good as the original paint jobs...

Think it could make someone very happy

Yes...British bikes of that era had a tendency..."to drip oil" and mark their spot.  :rolleyes:

My restored 1975 Norton 850 Commando MK III leaked...as did my 1970 Triumph T100C Trophy 500........ :shocked:

Oh well, part of the charm and character... :wink: :laugh: :grin:

Hate to break the stereotype, but the last 2 Brit bikes I owned, 1971 Triumph Daytona and 1973 Norton Commando did Not leak oil.
With tight top ends ( little  or no blowby), careful assembly with mating surfaces checked for flatness,  good quality oil hoses and  engine/primary breather systems that were well thought out.  Now , tickling the Amals..... but that don't count.

Really, who tickles their carburetors so hard that they wet themselves. :laugh: I like my bike but isn't this taking it a bit to far.

All Triumph bikes leaked oil in the 70's due to the antiquated casting process. The trick was to flatten the mating surfaces using wet and dry taped to a piece of glass until the surface was uniform. Et voila, no more leaks, ever.

Yes....that is a beauty!

Reminds me a bit of the paint work I had done on my 03' Bonnie. It never leaked any oil.

I built a bunch o' Brit bike engines back before I discovered Guzzis. None of mine or the ones I built for others leaked. But a few years down the road, it was when they started to leak, not if...
Crappy metallurgy, soft fasteners, '30's designs, old tooling, and outdated manufacturing methods were a surefire recipe for a leaky engine.
