Re: Lambretta Overheating

OK, an update. Took the scooter to my local Lambretta guy last November. There were marks on the piston and cylinder, from the nipping up, and carbon/oil sludge on the underside of the piston crown, but no obvious signs as to the cause of the problem. It had done 8000 miles since it's restoration be...

Stupid Question Time

An Li 150 will do 45mph at X number of revs.

Correct?

What Do I Call It?

Back in 1969, at the tender age of 16, I bought my1959 Lambretta Li 150 "Series 2". I still have it. After I'd had it a while, I had reason to replace the piston. I have no idea why now, but I did. When I came to fit the new one, it didn't fit. I think it was that the skirts were too long,...

Re: Lambretta Overheating

Thanks for your replies, guys. Some food for thought in there. TBH the weather should make little difference as standard Lambrettas sold well and ran reliably in warm climates and we've had some VERY warm weather for the last 2 Euro Lambrettas, with many riders screaming their bikes on motorways for...

Lambretta Overheating

Hi, I have a 1959 Li Series 2 150. It's bog standard in terms of engine/carburettor set up, and has 12v electronic ignition. It will do 55 on the flat, it's happy at 50, but I generally cruise at 45. The problem is that in warm weather(mid 20s degrees), on a long run it tends to overheat and seize. ...
