My bike has both a modded air box and exhaust and had no problems before it got flooded. It now no longer has the check engine light now that the juice box is uninstalled and all the connections are connected back to stockLJ. I've had bad luck with cars. It doesn't matter how hard I research or for how long, I somehow get screwed with the cars I've bought.
However, I've been very lucky with my bikes. Every single one has been golden. The 6r is definitely at top of the good-buy list. Try this:
Put the bike back to stock and ride the hell out of it. I haven't modded my bike. I say don't mod yours. Just ride the darn thing. It's a really good ride, stock. Just take care of basic maintenance and ride the heck out of it!
