We are fitting the Brand New Mugello 125 to 200c conversion kit.
This forms only a small part of the upgrade, as we will also be using a larger bore exhaust, better braking, 12volt electricals and a carburetor specifically tuned for the purpose. not only will this scooter be quick, it will stop when required and be ultra reliable.
The new Mugello kit looks like this. Cylinder with added stud holes for a better surface seal when the head is in place, cylinder head, piston, rings, and all fittings.
Super clean surfaces all round with the additional inlet port bridge.
Nicasil barrel lining with additional booster port.
Notice the little lip on the cylinder head. This matches precisely a notch on the barrel so that the two mate perfectly when attached together. We are told that this head and barrel are matched so perfectly, it could be run without a gasket.
The piston in the kit, is so accurately manufactured, it comes with a stamp on it marked "A". If, when you have covered many thousands of miles, you feel your piston is a little on the loose side, then simply remove it and fit the next one up. Marked "B". And so on! Genius!! Your local dealer can advise you changes to the kit.
The piston rings are amazing. A bit like those eye glasses you can twist and turn without breaking them. Exactly the same with these. They are meant to NEVER break. Also notice the clips. they have no ends on, because those are the bits that normally come off and get dragged up and down your barrel causing a seizure and damaging your barrel, head or much, much worse.
I'm going to stop drooling now or I might be tempted to just keep the thing.

Thats the inlet port
matched ports and additional booster port
What are the ports matched to and what does the additional booster port do ?
it could be run without a gasket. However, we will be using one
Is it not better to run without a gasket ?
piston is a little on the loose side,
What size is it ?
then simply remove it and fit the next one up. Marked "B". And so on! Genius!!
At what size would you do this?
Thanks for the heads up on the port. I've amended that.
Congratulations for your blog, I have found it today, and It has been a good discovery.
Thanks for your help, I'm restoring two lambrettas 1965 and 1962 LI and I will read it usually from Spain.
Thanks.
Daniel.
