Gentlemen

There are alternatives: Look at

1. Just Engines

www.justengines.co.uk

Replacement pistons and liners with real chrome plating to suit 46 SF's and FX's. I'm not sure about 61's though. Well priced too.

2. Saturn Hobbies.

They do a "plasma" liner for OS motors. Very pricey but apparently a real performance uplift and increased life expectancy. I don't know the web site for Saturn but they do have one. They advertise here on RCU. There is also a thread in this forum called "plasma liners" which will tell you all you need to know.
