Motorgeek is correct on this one. I called the company to advise them that it was using needle bearings & the salesman said that a pure titanium wrist pin would only last about a few days or so before it galls & fails. So as I was cancelling my order, he said that they titanium nitride coat the pins to achieve bearing hardness & strength. Do you guys think i'm beating a dead horse here?
Nitride coating is not new technology. I doubt if the bearing surface would last a couple tanks of fuel. I think that titanium products salesman is overselling the power gains for the weight savings the Ti wrist would bring.
Ti wrist pin and connecting rods are snake oil unless you are going to try spin the LT 500 15,000 RPM. We hang a pipe on the LT 500 that could be tuned for 15,000 RPM but the existing port design potential cannot be made to work very efficiently much past 8,000 RPM.
