Breaking in a new engine

[Papa Weeley_imp]

I'm sorry, but I'd have to see some kind of empirical evidence for this line of thinking; that just doesn't make sense by anything I've heard or experienced in 45 years of riding and working on bikes. Echoing what someone else said here, your buddy owed your wife a new bike. No way "riding it to redline a few times" would ruin a perfectly good, easily ridden motorcycle engine - particularly a Honda in-line four sportbike engine.
