Yep its a 252cc, I prefer the sound of 252 over 260 for some reason. The Vespa GT300 is only something like 275cc!!
Its only done 10 miles and its on ebay
When I look at that barrel I just don't see the port area to produce 30hp. I may be wrong. As for transfer timings after jacking up a TS1 to go with a 62mm crank won't they be a little high. Get ya port calculators out, at best maybe with -1mm deck hieght? (std barrel is 46mm from top of barrel to top of transfer I think)
Asked the chap if he had a graph to show the 30hp he said its just what he got told.
Is this the 'big spigot real deal' we've been waiting for?
