We're on the same page, I didn't mean to imply that it could possibly void the entire warranty. I know that it would have to be relevant. That's why I only commented about the engine. I don't know if Power Commander equipped motorcycles was ever denied warranty claims, but several years back I was researching fuel controllers to get rid of the decel pop on on my VTX. There was lots of chatter at the time of engine damage caused by PC running lean. It was attributed to bad maps being downloaded to the internet by individuals. I know that the Gulh re flash doesn't allow that and the maps are professional done and tested. All I'm saying is that no one is going to stand behind you if your power train is damaged, and it give the manufacturers a possible get out of warranty free card for those affected components. Not trying to tell anyone what to do with their bike or their money. I don't have a dog in the fight, my bike performs adequately for me as it was designed. Just offering an alternative view.We can talk about what-ifs indefinitely, and certainly, if a user did something to a bike like you're describing that directly caused a problem, Honda would have something to say about it.
Some people are concerned about having their warranty voided by doing a re-flash. That won't happen because any modification would be subject to the same principle, and that's simply and demonstrably not the case. I can change exhaust pipes, which can change the way the engine runs, and no one's ever had a warranty voided for changing exhaust pipes. People have long been running Power Commanders that change air-fuel rations, and no one has ever had a warranty voided because of it. Were a manufacturer to try to void a warranty because of a Power Commander, the motorcycle internet would light up. Beyond actually voiding a warranty, Honda might try to deny a warranty claim because of a re-flash, but as I said, they would have to show relevance. It would be silly for them to claim that a re-flash caused a brake-caliper to leak or a turn-signal flasher to go bad. If a re-flash caused an engine to overheat, that would be relevant, but the burden would be on Honda to prove it, and in any case that's not going to happen with this mod.
