New Product... We are proud to of been asked to help in testing of these new shock with Pro-Tech, has most of the scootering world already know Pro-Tech make some excellent shock's for lambretta's already, so i asked them about making vespa one's, after a few months of sending dimension's and details to them and discussion's over the phone this is the shock that they have come up with, prices are yet to be finalised, the shock is a fit for PX and other large frame model's, but you will need to fit the extension nut and rubber silent block to match your model, a Small frame one is due to follow soon. ...

Engine Tuning

On Small Wheels for all your Scooter tuning requirements.
Here are a couple of custom tuning jobs we have done:

EGIG 170

At present one of the best small frame conversions is the EGIG 170, these are maybe not the fastest of the small frame kits that are available but these are one of if not the best for every day riding, not just short distance but on long distance run’s as well, to date i have built 4 of these engine, including one for myself, i have more to do for customers and also one built by Erich himself, there is now available a 180 version and also a 250, which hopefully we will have a report on in 2023.

Mugello 185

The piston has been cut for the inlet… this piston is for TV con rods 110mm long.

We had the GP crank fitted with the TV rod also to match the piston and polished inlet manifold and ports..

The extra port in the piston was there from standard i do think its for a finger or scavenger port, that will be added next time the engine is stripped plus the manifold comes with metal reed petals so carbon have been fitted and also its only got a 4 petal block so a 6 petal will be modified and fitted also at some point soon….

Finished item all bolted up and ready to fit onto the engine…
Results of doing this have found that the low and mid range torque is doubled over the standard piston ported barrel, even with a peaky Scootrs exhaust.. jetting had to come down from 120 to 105 so fuel loss is much less, no spit back either..

So this has helped the conversion all round with more power, less fuel consumption.. and works out cheaper than a imola kit… thats if you got a mugello barrel already.
