I tuned an Electra X at 17,000 miles, which has now done over another 10,000 miles according to the owner. It is ridden quite hard and will go well over 90 mph and is frequently ridden long distances at speed. So far, so good. I also stripped an engine showing fewer miles than the former for tuning [sorry, have no record of the numbers on the clock] and there was a lot of play in the big end, so, perhaps it is pot luck, but one thing that will help kill a big end, especially roller types as found in these machines, is to plod or thump around at low speeds in high gears, on large throttle openings and I suspect many R.E. machines are subjected to such treatment. I have also seen a fairly low mileage UCE crank with a knackered big end, so let's not assume we are 'out of the woods' where big ends are concerned. Change the [correct grade and type] oil frequently, use the gears and let them rev a bit with lighter loads and they may just make it!
