Sure, Ron makes the best big bore cylinders you can
buy. But he's also one of the best motor guys you'll
ever come across. NRHS highly recommends a careful read of all
the tech information Ron is willing to share.
Disclaimer: some of the articles above are of
a less than complimentary nature with respect to the
products they describe. We have received, on more than
one occasion, strong reactions from the companies or
people representing the companies that make these
products, including accusations of having ulterior
motives and so forth. I guess that's to be expected.
Our promise to you is that we are telling the
absolute truth about our
experiences with these products and why we have the
view we do. We understand and
respect that some people may have different
experiences and views.
