Polini 177 kit cast iron barrel

Hi All, do you need to use a upgear kit if you use a 60mm crank,or use existing gear setup.[:bounce:]

did you work the valve & carters?
If you did and want to travel I’d go for a 23/65 with a 36 cogs fourth gear. If you ride in city original gear ratio might work…


HI JuanK, Thank you for this info,that saves £60 odd pounds, oldmod.[:roll:]

Thank you Matt, for your input

Leave the standard gearing.
