I just bought my 110 and It was shifting kind of hard for a while, but was still riding good. Then i started to climb a hill in 3rd and it wouldn't shift down. It still won't shift down and it's stuck in 3rd gear and theres no way for me to start it. Any help is appreciated.

pull the right side cover and check your shift mechanism looks like a star make sure the ends are not broken,output shaft,gears,etc

how do you find the output shaft in a klx110

output shaft goes to the countershaft sprocket
