Modern Vespa

Iv'e not seen a Polini kit but have fitted a few Malossi ones.

My only gripe with the Malossi kits is having to trim the head gaskets around the stud holes.

Not doing so can write off a piston and bore!!!!!

I'd say if the Polini comes with gaskets that are ready to use then I'd go with them.

In this day and age we should be able to make them from the factory to just drop on and not have to fanny about with gaskets.

So if your listening Mr Malossi, the phrase is "Could do better".

The rest of the Malossi kit is the dogs bollox.

You need the big valves and the correct porting which is the bit of the jigsaw that makes you see the picture.

With all the stuff fitted you'll see 19bhp at the wheel.

Miss any one part out and you'll be lucky to hit 15bhp.

And the new Malossi 4stroke crank is a must.

I've just had my first big end go on the first 19bhp motor we did a year ago and bet it won't be the last!!!

Was fcuking quick tho, a match for any unported 172 runner.

By the way 19bhp costs £2500 in parts & porting.

My labour came free on these development scoots but not now it's done and dusted.



Enjoy but don't expect a beast until the last bit of the jigsaw is fitted.

That extra 4bhp is well worth the spend.
