Just bought this bike recently and now my Ninja x6 that I have won't accelerate when I give it some throttle. I let it warm up for 3 minutes and when I'm on I give it some gas and it stalls out before I reach 5 mph. If you have had this problem and was able to fix it please reply because I'd really like to get my bike up and running. Also, I'm really new to pocketbikes so step by step instructions will be of most help if you know of any solutions. Thanks.
