The good: Thanks to Maxxh2o for sending me a wrist pin for measurement purposes. I have sent this pin off to PAECO industries to be replicated in titanium.
The not as good: $150 each unless I order 8 or more.
If any of you want one, send me a PM.
According to the guy on the phone, a Ti wrist pin made to the exact dimensions as a chromemoly pin will be half the weight & twice the strength. He stated that as long as they stay lubricated, then they should out last a steel pin 4 to 1 & that they have not had any reported failures due to fatigue. A lighter pin will allow your engine to rev quicker & make more power above 6,000 rpm.
I do not think the salesman is aware that a needle bearing will be running against the wrist pin. I bet he thinks that you are using this in a four stroke.
I will not use them.
Titanium connecting rods and wrist pins are ok if you are using them in a 4 stroke that does not have needle bearings in big end or wrist pin end. Titanium is too soft to work as a bearing surface.
Titanium is strong and light but cannot be be heat treated to serve as a bearing surface where balls or needle bearings are used.
I learned this expensive lesson about 30 years ago.
