Any one ever heard of an B model? I have a question? The specs of the the bike are as follows mods are a m4 exhaust. Plus it has a cluster from an 08 Z1000. So about a week ago I had to seal the tank from an over exposure to rain from the previous owners. After I changed the spark plugs, and re-gapped to the proper size the bike started to sputter between 3krpm and 6k rpm and would cut out before WOT. I changed the oil with 10w50(cause that's what Amazon sent)so the question I have is , can I get an accurate idle with the wrong cluster. The mph are way off so could that make the tac off too.?
