So you need lot of work on the cylinder.
However I don't think you know what you need! 210cc Fabrizi Cylinder needs 58 mm stroke crankshaft (Fabrizi). In my opinion the Fabrizi 180-210cc exhaust isn't very good, but expensive. I recommed you the Jolly, or the Malossi or even the Polini EVO.
You don't need C4 bearings! Do you know the original 180 cc NTN crank bearings they have a very big play as standard and they have a very custom size. All bearings??
Polini Speedbell is same as the original one, and the original dasn't got any disadvantage so I think you can save some money if you don't buy it!
Don't forget the CDI for you Runner, cause the original is retarded!!
32 or 34 mm carb seems to be a good idea for a 210 cc engine, but the Piaggio membrans (even a Malossi) haven't got enough area so you need bigger membran house and modifications if not the big carburettor is pointless.
I have already tuned 180 cc engines,and even modify runner to 200 cc so I think I know what I am saying, sure do what you want to do, these are my suggestions.
I hope you will have a good runner!
We are very curious!
