I’ve come across some right dip sticks in my time but this has got to be the best!

New Lambretta petrol tank cap with – a dip stick!

The first two people I showed them – went ‘wow I’m having that’!

Now we’ve all learnt to look down that little petrol tank hole, and wiggled the bike to see where the petrol is in the tank so you know how much oil to add on your fill up. Okay you can see the joint line and you can see the filter on the tap and you can see the ribs on the bottom of the tank – well that’s if you’ve got perfect eyes and the light is right.

But we’re all getting older and most need reading glasses, so instead of guessing and hoping – all you need to do is wipe the dip stick fit and remove it to see just how much fuel you really have! It improves that guessing game so you can be more accurate on mixing the fuel and oil.

It’s surprising how many times I’ve watched people fill the tank and totally guess their oil ratio.

Get it wrong and you’re weaker on the mix, do it enough times and on the wrong day – you’re in trouble! Add too much oil and you can be in as much trouble, not only does the motor smoke and drip oil at every joint – but you’re coking up the engine adding carbon to moving parts, potentially gumming up your rings etc.

Originally we was just going to make a stainless cap as we were sick of buying other peoples caps. Stainless is not really needed, but thought let’s think out of that box! This was quite hard, how can you improve a simple petrol cap? Then a light bulb moment – fit a dip stick!

These fit all Lambretta Series 1, 2, 3 petrol tanks and any tanks remade that uses a standard cap. The dip stick stops just short of the bottom and is marked 1/4, 1/2 and 3/4 too full.

This dip stick is a height measurement not a volume measurement. So it doesn’t matter if its a standard tank, mid range or long tank. All you need to know is how much the tank holds full and at the other marks. If you want to be anal, make more marks in the plastic.

No more need for smelly bits of wood, no need to carry a hammer or carry steel rods!

Comes fitted with a MB Viton seal.

Of course you still need a mixing jug to get your percentage right!

Makes the mixing much more accurate.…/lambret…/mbl0313k.html
