I change the rod out when the tolerance is out more than .0025". If taken care of, that is right around the 5 gallon mark give or take. I have run the R7 rods in a couple engines until the engine ran erratic because of too much play and the timing and compression were changing as the engine ran with all that slop and I got around 9-10 gallons out of it but definitely not recommended. The instructions say to change out the rod every 4-6 litres or 1-1.5 gallons but that is a little too safe. You should be able to squeeze 3-4 gallons out of a rod easily if treated well. That means preheating the engine before each start, keeping an eye on bearing and rod wear from time to time, running good fuel with a good oil package and keeping a good tune on it while keeping foreign debris out. It can be hard to do all of the above all the time but it is possible.
Better is spend 60 bucks than buying new engine 
Regards!

aint that the truth 
general maintenance on any engine should be had , imo engines are not throw aways as some others think they are , EVERY SINGLE part of the engine can and was meant to be disassembled

True to point. Simple maintenance like a bearing, rod and a resize is acceptable but if a bearing or rod bushing comes apart or foreign debris goes through an engine and the psr is junk and the bearings and crank are questionable at best, then you shouldn't be sinking money into it to rebuild because most times rebuild cost will be at or more than replacement cost.

I mean better is change rod than change everything inside / buy new engine through rod crash.
