I thought that over the last 2 years my playing with my D14 had achieved a good everyday looking bike.

The starting hadn't been too good but with a bit of tinkering it was fairly good although a bit intermittent.

From the outset it had been smoky, I thought I'd been a bit heavy handed with the 2T oil so reduced the mix & even added a litre of neat fuel.

Still it smoked, anyway the other day I thought I'd check the gearbox oil, I had refilled it to the correct level after refitting the primary cover.

So, there it was , nothing coming from the level plug & needing quite a bit to top it up again.

Having been an ardent follower of the site & forum over the last couple of years my thoughts are that I have dodgy crank seals.

So now a further adventure starts ! I've ordered new seals from Rex. 

I spent my working life in the motor trade & have stripped & rebuilt countless 4 stroke engines but 2 strokes are another thing.

All good fun & a learning curve.

I'll look forward to using all the knowledge I've gleaned here & will hopefully end up with a lightly hazy good starting D14.

My thanks to all contributors on the Forum.

If you have stripped and rebuilt 4 stroke engines, a Bantam engine will be a walk in the park (are we allowed to go for a walk in the park just now?)

I am curious that in the owner's instructon manual (D1/ D3) it says every 300 miles check oil level in gearbox and top up if necessary. I'd like to know did they think this is normal, and where did they think it goes?

Most of it finds its way past the output seal, onto the chain, then all over the back end of the bike. 😃👍

I wondered why my chain always looked nice and oily not having oiled it since rebuilding it 🤣🤣🤣

...the rest possibly finds it's way down the gear shaft and waterproofs your right boot. whistle

Sometimes oil just weeps past seals. It's a fairly common problem with old Moto Guzzi's, re using synthetic oils. The usual advice is stick to mineral.
