I replaced the clutch. The clutch is fine now. the problem is still when i pull the clutch while the bike is in first gear, it locks up like the clutch isnt pulled in. (while the bike is off). my little brother put the bike in first gear and pushed the bike. we didnt feel any compression from the engine. (when normally you would feel the compression from the piston jolt the bike.) we did not have any compression. he thinks the woodruff key is broke. would this cause my bike's symptoms? how hard is it to change the key and how hard is it to get to? also is there anything else i can do to further diagnose the problem. thanks fellas. reading this is probably a pain in the ass to follow... try pulling the clutch off 3-4 times and figuring out the clutch isnt the issue haha
