Seeking advice before converting from old Malossi 210 to Polini 221.
Have S&S 62,5mm crank, casings optimised for this crank and Malossi 210.
S&S reed inlet. 28mm keihin. Also have available 33mm keihin. Think 28mm is the better to use?
Standard Lusso 200 gearing with T5 fourth gear.
S&S silent exhaust for Malossi 210.
I will optimise casings for Polini 221 cylinder and use a GS piston.
Seeking advice on what gaskets to use on top/bottom of cylinder (someone told me a thicker than standard gasket on top is not possible on this kit??) with this setup with 62,5mm crank.
Also seeking advice on gearing. I have a cosa style clutch so since the Worb5 ultra long gearing is quite expensive, I am thinking of using a 24t clutch center and 65 or 64t primary gear. Any thoughts about this?
Thanks in advance for any input from anyone who have experience with this!
