2011 cbr 1000rr engine shuts down when driving
 

I was riding my bike at low speeds around town for 20 mins and then I took it on a highway. Going at 80 mph, slowed down, began downshifting, the engine died. Started the engine, rode for another 20 seconds, same thing happened. And then again and again. Feels like it happens at lower rpms.

No red light or engine light comes on when driving.

The bike was struggling, making this weird sound between each time

Bike has 8300 miles.

Or tank bag on top of the gas cap?

Next suggestion: failing ignition pickup - expands when hot, breaks contact.

The 08-11 Fireblades were prone to crank twisting I believe, not sure if this caused running problems or just transmission noise. Anyway, I suggest if you take this question to a Fireblade dedicated forum (there is one on Facebook, Fireblade Owners Club, free to join the page) you'll find a lot of experience to help you diagnose your problem.

2011 was a cross-over year for the blade. . Are you on carbs or FI ?
