Andy Stephenson Posted March 16, 2021 Share Posted March 16, 2021 Brian Gardner who does an excellent job of recreating these parts as they should have been made in the first place has produced batches of OS61 RF and SF piston and liner sets. I had a set for my RF and the engineering is superb. He does however need commitment of 50 or more to sign up to make it worthwhile for each type of engine. There may not be another opportunity if he doesn't get enough interest. Take it from me if you have one of these engines that is need of an upgrade/repair it will be well worth it. Andy.

Nigel R Posted April 22, 2021 Share Posted April 22, 2021 If anyone is interested, the gent in the states who took a bulk order of 61 SF/RF piston and liners, still has a handful left. I'd second what Andy says about the quality - I'm replacing two failing liners with Brian's parts, they are superb. They have also been made with long exhaust timing (as per the Hanno engine) to get a bigger boost from tuned pipe use. See this thread The FSR/VR order is still open I think. Again, port timing is with slightly longer exhaust for use on pipe. Quote Link to comment Share on other sites More sharing options...
