Must admit Richard I cringed a bit when reading it won't go above 5000 rpm with just a few hours of running😲
I think these engines do need careful running in and also warming up before hard use. Although I tried to adhere to this, when I picked up my M3W from new I had a 3hour motorway drive home, I tried to keep the speed down and vary the revs but I recon this is what damaged the bores causing it to need new pistons and barrels at around 2000 miles. Could of course just of been one of those things but the engine sound definitely changed on the way home becoming more tappety. Didn't make that mistake with the new barrels adhering to S&S running in recommendations👍
