Re: Polini exhaust

I think from the factory the later electric start models had the ignition backed off a bit and set between the A and IT marks but only one way to be sure. Pop the flywheel.
My mates bog standard P200e still runs 23 degrees problem free and that`s with the crappest two stroke he can find :D

Re: Polini exhaust

I`ve been running one on mine for a while now. Changed from JL r/h and the difference was massive. The JL was dead down low but the Polini restored that and still had the same if better top end power. I`m on a P200e with BGM top end( which is just a standard 200 top end in all but name) I had a 124 ...

Re: Changing Rally cylinder, need to remove the engine?

That works a treat, better than removing all the cylinder studs which also works. They`re best left in and not disturbed.

Beedspeed Thin Ring Piston vs Grand Sport

Wondering if anyone has any experience of the Beedspeed Competition thin ring piston, seems great value at £48 quid as compared to the more popular proven Grand Sport version at £95 quid. Planning a mild O-tune on my P200e. https://beedspeed.com/collections/vespa-pistons/products/vespa-piston-kit-p2...

Cylinder head Compatability Polossi 210

Re: BGM CARB

No need, I have the same set-up as yourself and on the open road I only use full throttle if I`m on my own, never any problems with fuel starvation.

Re: Jetting advice DR180

I`ve done a few with SIP Road pipes, standard jetting apart from an increase on the main to 108.
With the Sterling maybe start a bit higher 112 and work down.
