Our last Dyno before we close for Christmas!

A lovely result 19bhp @ only 6000rpm, and 17.5ft-lbs @ only 5500rpm. Power starts at just after 3000rpm, peaks at 6000rpm, and revs on past 7000rpm.......nice spread. A great touring setup, this will be a pleasure to ride!

Fancy more power & speed? Just change the pipe for something more sporty and watch the revs and BHP rise!

Merry Xmas everyone :)

thats a great result especially if you compare the torque graph to say a TS 1 !,and from only a 172 vespa !

The best results in terms of peak and spread of power can be achieved with the Quattrini pipe. Trust me.

It is a great result Sean & I'm very happy with it :D .... but the child in me wants to explore further what it'll do with a different (revvier) pipe - so need to decide on either; one of Pipe Designs offerings - or the dedicated Quattrini pipe..... and then possibly a 60mm crank & 35mm carb aswell :lol:

try another pipe first graham ,as its the easist option to attain more revs and bhp and speed on the gearing you have in it ,torque would drop a bit but you have more than enough anyways .
I dont think much gains are to be had from a bigger carb on this if any tbh .
nor the 60mm crank ,bearing in mind the cost etc ..the longer stroke will in fact inhibit it spinning up as readily and only add more torque
