I could buy Hyper engines 21-28, or OS... March....savage 4.6cc......savage 4.1cc choice is endless but price isn't.[&o]
Would parts fit ane annother? EG. 3port piston and sleve in to 8 port with good effect??
Could you point me to website with original parts for Hyper 21 8port engine as I can't fing any of those here. That would be my preferred option to rebuild my engine.
Cheers,
