Years ago, Frank Bowman was the provider of a wide variety of piston rings for our engines.
In 2017 he sold his business to Bjorn Baal.
For a while, Bjorn did business by email only. I reached out to him just yesterday and he passed a link to his new website which is a huge improvement to his accessibility!
https://rmjmachineworx.com/I'm rebuilding a Super Tigre 90 and Bjorn's response to questions was nearly instantaneous - literally within just a couple of hours!
I've used his rings in ths past with success, and I'm confident that my newly ordered Super Tigre rings will work great.
