In recent days we have discovered an issue with the max bore size for the Mini Swift and KA100 engines. In both cases, when using the largest size piston available, if the clearance is excessive (a well-worn engine), there is a chance the stated maximum bore size could be exceeded.

Until further notice (the 2024 fiche factory document) the following maximum bore sizes will be in effect.
  • Mini Swift - 42.21mm (1.662")
  • KA100 - 48.69mm (1.917")
