What is wrong?
Bought a 2009 ninja with 1200 miles. Guy had it tuned and oil changed in fall, but did not ride it. Stored in garage. I had to take it home with choke on.
Replaced the battery so it starts, but dies when you give it throttle. Unless you let it warm up, then you can rev the throttle. If you lower the choke it revs weird, up and down. Give throttle and it dies. Put it in gear let go clutch, give throttle it dies.
I think I have a paperweight. Can't afford taking to the dealer. I put new fuel and seafoam in it. Still could not get it going down the street besides the night it was brought home with the choke on.
