Then moved on to the headset. I tried to fit the gear change (expensive one from a well known Italian make). That didn’t go well. The handle part is out of plane with the housing part so when you twist it, one side grinds in to the handlebar. That will be going back.
I then moved on to the throttle side to encounter this:
At this point, I laughed and packed up for the day

Sheet foam is available & can be shaped to fit the space available.
My thinking would be two undersize oval ends, one with hole to suit the elbow. The wraparound 'cylinder portion is then hot glued to the ends. if you think of how an oval silencer is made, the principle is the same.
if you wanted, there could even be a spout connection to the air scoop hole (50 mm bore) with a foam baffle piece internally so that a mix of some fresh, filtered air would mix in with the under panel 'stagnant' filtered air.
I have found that good filter foam barely affects the carburation but that the connection elbow volume is quite critical. Even a 40 mm bore elbow with no filtration fitted will choke the Dell'Orto you have. Well, it does on my engines PH's do not have a built in, well though out overflow/anti-flood as some carbs do. Another reason that PWK's are a revelation
Dell'Orto PH range are very prone to hot start issues as in the kind of flooding you can barely see. The fuel expands in the carb & richens up enough to cause problems on attempting to restart. You may need to add an overflow to the bellows. An old bicycle gutted inner tube valve suffices, as low as can be fitted, with a piece of plastic/rubber pipe stuffed with a bit of wire wool @ the exit to avoid dirty air getting sucked in. The pipe can even be routed through the flywheel cover clip (if one is fitted as with early GP's)
I hope that helps

I've done 2 reverse pull drums. Both were very effective and I still run one now. The first one I did used a gp cam and while it stopped well, it came on so suddenly that I was scared to touch the lever! So I put it back to standard.
I'm not certain that it was the different cam that caused this, but it's all i can think of.
Just a tip in case you find the same issue.

Somewhere on this Forum I posted some pictures, but as I seem to be so vocal(!) they'll take some finding.
If you do want images, I will find some.

Cheers. I too ran one on another scooter fitted with this engine. I have spent some time fettling the shoes to try and ensure they both engage at the same time. I shall consider what you say about the GP cam if it is fierce
