how often should i change the conrod?
I don`t race, just drive for fun at the lokal track
I still run this older motor too. And the parts are getting harder to find. What I have been doing is buying New OFNA Picco motors on ebay for $65.
All the parts are interchangable, just make sure you put the shim back until the piston sleeve. (If you have the "tuned" version). As that shim is pretty much non-replaceable.
I have never changed the con-rod on the motor, and i have 3 gallons thru mine. I do take it apart every gallon and measure the bushing though, and check to make sure its not stretched. Once its stretched, I just replace the motor. ($65!) This motor will most likely start leaking air before your con-rod fails.
