Did he drop it while it was running? Tipover switch may be triggered. Reset the ECU.

Depends on the brand of battery. Yuasa are good and strong while they last, but when they go away.... THEY GO AWAY - no warning! Once dead, they're pretty much dead. This is sad, considering how expensive they are. I found better MC batts, based on the Sears Diehard design, and have never looked back. Yuasa is crap in comparison. (email - i'll share!) That said.... A general rule on MC batts: - LOW cycle trickle. Avoid burst/fast charges. - once peak charged, if you have no intention to use them right away - pull them off the charger! - measure every few weeks, put them onto a charger later... far better for a battery! (you have to exercise it!) - monitor the charger - cheap chargers don't scale down properly: they overcharge and quietly burn out your battery! M.

Ditto on the "be careful" comments if this really IS your first bike. This will not end up well....period. I'm not going to lie: it's going to end up ugly, no matter how "nice" you decide to try and wade into riding sportbikes using an XX as your first. No matter now cautious you intend to be with this machine, it's going to bite you. Forgive me, but it is simply NOT a good idea for you to have this one as your first. Others can gripe and complain at me for my stand on this. I'll happily listen to their liberal thinking....right up until we hear about how you die or are maimed for life, and then want to blame Honda or someone else because you weren't told, "NO." Take some responsibility, my friend, and smarten up. Put the XX away. Put your ego away. Both will get wrecked using this machine as your first. Start on something small. You're going to wreck a few times while learning; you best not hurt yourself... or other people... while doing it. Save the XX as a reward. It's well worth the wait. Trust those of us who know. We want what's best for you. M.

Dynojet, baby. Their R&D is far superior and not based on "luck" in order to stumble upon what works. (sorry, FP fans! I will admit: some FP stuff works....from time to time, when they get lucky...applications WILL vary...) M.

Don't discount this: one becomes focused on something, and it's suddenly "there." A kind've "hypochondria" in the owner's mind: They listen hard enough, and the normal XX rattles, clangs, farts, hiccups, and whines make the paranoid listener convinced that their machine is "broken." All-the-while, it's happy as hell... That said, if I have to believe something here is busted, I'm going with cam chain rattle on this one. New tensioner or not, it's what you're describing. Simply put, you may have gotten a bad one as a replacement - it happens. M.
