The best piston for the conversion is 12110-29900. This has better ring pegs and cut-aways around the gudgeon pin. The rings are 12140-29010. Sadly, I know these numbers off by heart. I'll get my anorak. Adding a few more TS185 ER part numbers to the above for future reference. The gudgeon/wrist pi...

Can anyone please share the Tsubaki part number for an 80 link duplex chain?

Would also be interested in the part number for 82 link chains, or any other Lambretta compatible Tsubaki chains.

Thanks in advance!

A full DC set up with a DC horn (original or remade) is loud, and has saved me several times from careless NYC taxi drivers. Bright lights from the conversion are an added bonus.

Thank you. After oil ratios and tread-patterns, nothing will generate a diverse range opinions quicker than lower guides :lol: I'm not really interested in discussing the pros or cons of lower guides in this thread, but seeking input on which push down tensioners, if any, are compatible with lower c...

Which push down chain tensioners are compatible with lower guides? GT? Jockey’s? Casa? Others?

My lower guide of choice is the Stratos (also recently cloned by Scootopia) but will consider others, if needed.

Thanks in advance!

They’re from a BSA Bantam, and unless someone has redesigned them specifically for Lambretta dampers they’ll always be a little loose and slightly too short.

As mentioned above, a small zip-tie fastened around the top will stop them sliding down.

Also Cosmoto and I believe Pipe Design have one in the works. Here are some dyno comparisons of various pipes (might need to log in view).

There is an Italian company that manufactures both the S1/early S2 type and the late S2/S3/GP type (and for several models of classic Vespa), but the name escapes me at the moment. Both RLC and SIP retail them.

For 12v AGM batteries for late S2/S3/GP see this list.

Series 1/early Series 2? Or late Series 2/Series 3/GP?
