Hello,
I was thinking of boring a spare 9E barrel to take a 1H piston for a 225cc conversion. I checked out the dimensions at the bottom of the barrel spigot, particularly iwo the inlet ports, and there doesn’t appear to be enough material for it to be rebored to at least the required 63mm.
Has anyone else successfully converted a 9E barrel and was it necessary to modify the inlet porting?
Thanks for your help.
Regards,
Tony
