Sorry it's the actual off the shelf polini kit to suit the 60mm crank plug and play as it were !

I think the Polini 207 with 60mm crank is just about the perfect touring set up. If you put the 1.5 mm packer on the base gasket and adjust with a few extra thin gaskets to get the piston sitting 0.5mm from the top of the barrel, then the porting is a bit longer on the transfers and it will rev a little more. Or you can set it up with the piston about 0.5mm out the top of the barrel with a deep head, if you are planning to upgear the primary.

i'll tell ye exactly how the 220 polini performs...my spec is - alloy polini 210 barrel, casings matched, pinasco re-profiled 10-1 head, 1.4 squish? i think, 1.5 packer, pinasco 60mm crank+inlet duration worked, 24/24 carb+carb inlet worked, main 128, Be3, 140 air corrector, 48/100 idle, standard 4th gear, jL r/hander, dyno'ed at 19bhp/17torque...i personally asked sean/dan for a tourer and thats exactly what this engine does! it's a low revving thumper and pulls and pulls, i personally cruise 60gps uphill/downhill and in headwind @ 1/3 - 1/2 throttle 120-140mle to the tank, i have gps'd scoot at 70 then backed it off, not really wot i'm about now! the polini will never be a malossi. malossi's a very quick of the mark but fade and thirsty, this polini tune is subtle of the mark and a thumping pulling machine with economy, a very happy owld man me!!!! :D

Thanks lads , sounds a goer, Polini after they brought out the alloy 210 kit , made one with a head i'm led to believe specifically for the 60mm crank. No packers needed etc.
Must be pretty thin on the ground as looks like everyone out of stock.

Wasp supplied all the gear for my build and he mentioned the new polini kit was coming out, that was about 4 month a go, so maybe if anyone can get it he will. He's a good lad wasp!!!!
