Funny you should ask.
The company I work for has a model agency division, and she is one of its clients. During London Fashion week it was all hands to the pumps, for a bit of overtime, so I'm at the Natural History museum marquee thing, where they have a catwalk show on, and backstage I literally walk into Kate Moss. Naturally I apologise, and being a cool sort of fucker rather than completely starstruck I say hello and we strike up a conversation. Turns out she owned a Vespa Primavera and so did I. She told me how the two stroke engine is inherently efficient due to the fact it makes power on every other stroke rather than one in four, but suffers from poor exhaust gas scavenging due to the valveless design. She remarked that expansion chamber exhausts, which use reflected sound waves to push exhaust gases back into the combustion chamber are capable of not only cleaning up the emmissions but offer a greatly improved power curve, she added that the nature of the power delivery could be tuned by altering the length of the pipe and the angles of the exhaust cones. Then she explained to me how modern reed valve engine designs are capable of much more power and cleaner power at that than traditional piston-ported induction systems, though the vespa's rotary induction, in which fuel and air enter via the crankcase and are then carried by specially shaped cutouts in the crank to the ports which the piston then sucks into the combustion chamber, is a good halfway house between the two. Piston-ported designs, she mentioned, are robust and reliable, and require much less 2-stroke oil to be mixed with the petrol. Whereas a piston-ported design might require a 5% mixture, Miss Moss told me that a rotary induction motor only required a 2% mixture. If you used modern synthetic oil you got a much cleaner burn, which was not only good for emissions, but also for engine longevity. Intrigued by her in-depth knowledge of the Vespa engine I asked her what she thought its limitations were. She responded that because a two-stroke cylinder is full of holes it is a stuggle to keep the cylinder from becoming oval as it heats up, due to the uneven heat distribution. And because the Vespa engine was air-cooled the problem was magnified. Whilst water-cooled two-stroke 125s could make a reliable 30 bhp or so, you could only get half that out of a Vespa motor before there was a serious risk of it seizing. Kate then pointed out that this was a bit of a moot point, because due to its humble origins the Vespa had a very small 3 plate clutch which really couldn't handle much more than 12bhp. I had to agree as my Vespa used to destroy 2 clutches a year.
Anyway, I could see the floor manager trying to attract her attention, so I let her go and prepare for her catwalk, and went off to talk to Naomi Campbell.

So, in answer to your question, no she hasn't.

thats two strokes more than that drugged adled twat pete gave her

boom tish... thank you thank you...

beer o-clock?
