I'd say you could probably have good, or you could have cheap. Rarely you can have both! |

Russell Engineering pistons (with Nippon rings) are good too. And they sell a 72.5mm, which Hypatec do not. Gives you an extra rebore size between +.060" and 73.0mm. Available in 72.5, 73.0, 73.5, and 74mm sizes. [edit] it's a bit sad that everybody in Oz seems to be out of 1275 Hypatec +.040 and +.060 pistons at the moment. I have 1 new set of Hypatec +.060", with Hastings rings, if this helps you. [edit] now sold. |

I just came back from Karcraft, they now have stock of 9.75:1 1275 pistons in std, +.020",+.040", and +.060" sizes. Brand is `County', they look practically identical to Hypatec ones. Price is under $200/set. HTH, |

Sorry no I didn't ask, but they do stock Hastings rings. Email Karcraft and ask. I have been told these County pistons [edit] may be Taiwanese, as are Hypatecs and Russell Eng ones. Note: I have NOT used the County pistons, so have no 1st hand knowledge of their fitment. |

To take this thread on a slight deviation from it's current path; does anyone know who or where to go for "custom" or off the shelf pistons suitable for creating a stroked engine using cooper 's' rods on a large journal crank? |

Just use Hypatecs (or maybe these County ones)- if your crank is stroked 3mm, machine 1.5mm off the piston crown and redo the dish. Both these pistons have a thick crown, and their ring pack is well down from the top (compared to Russell Eng ones) so stroking is no problem. PM me for further info. |
