Recently my X has began making a clunk noise when I am trying to start it with the E start. It will be turning over then clunk, it stops. Doesn't seem to happen when kickstarting allthough it does sometimes kick back and it also sometimes feels like it is skipping gears when I'm kicking it. Also today I noticed the compression seemed to increase, and it seems to have stayed that way. (Noticed when kicking it) Any ideas what my problems(s) may be?
