I purchased a basket case KF5 a few months back and finally got to the test run phase. The engine was pulled from a 150 30 yrs ago and well the run didn't go so well. Shut down for low oil pressure and max rpm was 1400. So now I get to rebuild. Lycon in Visalia can do the top end and grinds and set the engine up for 125hp as an experimental with port and flow and high compression Pistons. They say this will not effect normal wear parameters or tbo. Anyone have thoughts? Opinions? Suggestions? Experience? Know a friend of a friend who knew a guy who had an uncle who had one?
