If there was one major thing have learned about Lambretta’s in the last few weeks is that they are a 1960’s two-stroke based technology.

What this means for me today is that the engines themselves require a lot of new technology to bring them up the the modest standards that I had with my 1983 PE200, however, I was expecting this and was excited to see so much “kit” on the market to choose from, way too much kit on the market.

After reading through the books mentioned in the last post and coming to grips with what was ahead of me I wanted to reacquaint myself with two-stroke technology.

So I did what most people do, I searched the “interweb” (not googled it) - my search engine of choice is Bing for the time being as I feel Google is not doing very well with returning relevant results any more as it has become bloated (work related rant over).

Seriously though, Bing turned up some great sites for me to look at that had the type of content I was looking for, the best for me was a really simple site Free Engine Info, it had a few good articles on two-stroke technology that I was looking for - particularly on porting versus reed valve induction, carb tuning and exhaust pipe tuning.

A lot of this I had vague memory’s of from my Vespa riding days, I did have a tuned expansion chamber on my 1993 PX200 although back then I thought it was to make the scooter sound louder, not make it go faster.
