I have a 2012 ninja 250. All was well when I went to the store. Got off, shopped, 20 min later got back on the bike, and it barely would accelerate. It was the acceleration of a turtle pulling a tractor. Rpm would only go to 9000 max. Top speed of 40mph if I'm lucky. It's like all power was lost. The clutch feels like it connects. I'll add more info as I find out more.
Thanks everyone
