2001 yamaha yzf 600r the key is turned to lock

Question edited to add a lot more clarity.
Question moved from Cars and Trucks to model category.

First you connect a scan tool and read the codes. Then the code tells you WHY you are in Limp Mode. Then you fix whatever is wrong and the scan tool rests the code. Limp Mode is ONLY activated if something is wrong that can catastrophically damage the engine. You don't just turn it off and hope for the best.

Your carberator needs to be rebuilt or replaced.

i suspect the battery is problem.Also you may have an electric fuel pump that is acting up.
