O-tuning V5A for my elder son (hot french recipe inside)

Nice work fogger. Hope the young lad appreciates what his old man is doing for him. Looking good. Glad to see you back working on vespa

My soon enjoys the whole project but fears a bit the gear change thing. I guess I felt the same when I was fourteen/fifteen.
I should have the casings back from the welding shop next Tuesday.

can i ask how you dug those boost ports out?

[fastfrog]

with my teeth!
....and a mobility flexxi. great and easy to use as a grinding tool. Far better than any pneumatics or loosy dremels... speed controlled by pedal, lots of torque instantly poured even at very low revs... A dream for any old fashioned tuner...

[jackson85]

Ah he will love the gears frogger. Riding an auto is for lazy people

[fastfrog]

Sure, or I'm good for a paternity test!

welding job and 2,5 mm packer done:







transfer prints are just for show. They will be a bit smaller....

nice work ,will you be keeping the std (16/10)carb or using the better 19mm one as used on bigger 90/100/125 vespas ?

[fastfrog]

I guess 16/16 is a perfect match....

Looking for a decent head, I must admit the original one is a crap without no Squish band at all and a lousy cup shape. Polini does one a bit better for its 50cc kit. It is oddly too large with 41,8 mm for a 38,6 bore. I can imagine the pinging noise from my seat. Anyway I can schrink it to 40mm by skimming it.
Need to check if squish ok with a meteor piston.
