Hey guys my nephew has a 300ex and he needs some help.
Every time he pulls the front tires up to wheelie or tries to climb a steep hill his quad cuts out really bad or just dies. We checked the air box, cleaned the filter, changed the plug, changed the fuel , and his dad checked the carb. Any ideas would be greatly appreciated. We got a big day of riding tomorrow and it will just kill him if he can't ride.
Thanks
