Question
  • Q. Can I still use standard cylinder head and what size of main jet in carburettor should be replaced on this kit?
  • A.

    Standard cylinder heads are compatable with these cylinders. For the main jet you will want to go up around 5 sizes larger as a starting point, you may need to fine tune from there.

  • Q. Hi, Does this or any of your other big bore kits fit the Scomadi TL50?
  • A.

    It looks like Scomadi have had 10mm small end conrods fitted to their engines instead of the normal Chinese 13mm one which effectively means that you can only use cylinder kits supplied by them unless you swap out the crank or the engine.
