Yes you can. The five port is the same as the piaggio 150. The only difference is the cylinder ports are wider with divider piece for strength. So it is still a 3 port, but looks like 5. Piaggio heads are top quality. The later 150 lmls went back to small ports. Rob.

Thanks. I have damaged my lml head but i have a vespa one was worried about the copper gasket because the vespa head is flat where as the lml head has a groove for the gasket to fit in,Also the lml head uses a longer spark plug

Yeah, px150 used short reach plug. And no gasket due to quality of casting. If you are worried about your cylinder top buy a vespa 0.8 mm copper gasket, or try as is. I ran a Vespa 150 top end on lml large port cases for years. Rob.

Thanks Rob ..so the vespa px 150 head will go on my Lml 150 5 port cylinder. Im not putting a vespa cylinder on. You ran the full vespa top end on your lml not just the head ??
