Modern Vespa

the next project i will do with a friend

fitting 2 493cc Cylinders and pistons from a Fuoco / MP3 500 on a GP800

it will be a 960cc when done a real R1 killer topspeed of 220 or 230 GPS




Pics will follow as soon as we start

From left to right 460cc 400cc and the 493

can't wait to see this project and pics.

Because I have already been interested in such a conversion, I am also very interested in the topic.

How will you solve the problem of the timing chain tensioner on the horizontal cylinder? The cylinders of the master-engines have the timing chain tensioner on one side only and for the horizontal cylinder on the GP engine thus on the wrong side? (GP cylinder have on both sides the opportunity to install the timing chain tensioner).

Hi Maksor,

Don't want to hijack the thread as i am very interested in the outcome, but looking at the pictures, do you think the 493cc cylinder will fit a master 460cc engine?

I know the 460 and 493 differ in bore and stroke, but i'd love some more torque on my Beverly

Best regards,
Otto

yes it will fit maybe we need to machine a 5mm off on the bottom off the cylinderwall but then you will gain 20cc

the 460 is a 458.7cc the 492.7 with a stroke of 69 becomes a 478.9

on a GP800 you will gain 140cc

here some pics

Is that the engine you're going to be putting in the Tricity?

No hehehe mayby on the Fuoco

Gilera GP1000

There is the Idea from but moscatelli is to expensive when you want it all this will save you half the money when you use the Fuoco cylinders they are about 320 each the complete set from moscatelli is 4500.- euro not installed

Now hed did spend about 2000.- euro

my friend did install a Rapidbike and a 45mm injectionhouse
