Default Re: Hello from Texas

Like Tom said, welcome to the forum. I got into these in 2010, all of the newer engines have needle bearings at the piston pin, unlike the early engines with a bushing. We have seen a few improvements the last couple of years but the engines are basically the same design. The good thing is there are a lot more suppliers of parts both stock and after market from many vendors, a lot of which advertise on the sides of the forum.
Your results may not be the same,Greg
