Px barrel

[nickj]

So I’ve rejoined the modern lardy club so I’ve got something I can commute on - a cheapish 64 plate PX which was a cat N insurance write off. It’s got a 24mm carb and a Readspeed pipe, but I wonder if anyone can identify the cylinder without me having to pull the head off? I was thinking it might be malossi from the Brevetato stamp visible?....or is it just a bog standard job....

[triffid]

Just had a look at my 2017/18 150 barrell and it has no name stamp, apart from that can't offer any further advice.

Brevettato means patented I think (Max - where are you??)

All the images of Malossi barrels seem to have this mark - will pull the flywheel at the weekend to check....

[tzsteve]

spot on,, Brevettato means patented

according to collins online dictionary

but whats going on here  the stud at top left looks a bit wrong,

i don`t think i have seen other vespa cylinder studs cut for a screwdriver

[nickj]

Yes I wondered what that was - I guess it just makes it easier to install and remove the studs to take the barrel off while it’s in the frame. They look hand cut with a saw...

Will investigate at the weekend...

Dropping the head never did no harm. You can always convince yourself that you need to decoke it

Or...

Drop the flywheel to reveal the Malossi logo.

It'll be a malossi 166.....
If it runs, hooooons and makes a nice serweet sound .....leave until you've broken it

Ooh yes it definitely does that! Thanks for identifying

It’s got a JL exhaust with a reedspeed end can and a 24mm carb. No idea what’s inside but will wait until it needs tlc before investigating more. Got to sort a sticky front calliper first. Shoved some BGM shocks on it at the weekend and then spent an hour sorting out the sheared stud on the rear hub. Its definitely been neglected for a while but enjoying sorting it. Need to check the flywheel next to see what it is
