cheers burty.
Hi. I would suggest regular con rod changes about every 1.5 to 2 gallons just to be safe. You can go more, but it gets more risky the longer you wait.
The bearings should be good for 4-6 gallons. The Piston/Sleeve will last about the same. There are exceptions, if you don't push the engine to it's limits it will last much longer.
When the Piston Sleeve starts showing too much wear, you can send it to me. I can resize the PS set. It will last another few gallons, and run like new.
Thank you for the support. It's always good to hear back from you guys.
