2008 NRS. Since day one, this bike has started at the touch of the starter button. It literally didn't crank one revolution and it was started. Now......no recent changes.....it seems like the bike isn't firing while it's cranking. It will crank and crank and crank but does not start until you release the starter button. Thats what I said.......no fire until that millisecond when you've let go of the button, and the engine is still spinning. Some times it sneezes back through the air can. Other time it fires up. But ONLY at the moment you release the starter button. Ideas?
