04 kx85 Kickstart/compression is to stiff/high to kick over

[Nzain1]

Hey guys I'm a new rider and in my noobness was pushing the 2-stroke kx85 hard on a main road in third gear then went up a hill in third and the bike sputtered out and died. After it died the kick start was stiff and very hard to push down, it goes down but I'm unable to kick it over.

When I talked to some friends, they thought it could be a blown top end, so I took the cylinder head off to inspect the piston and the piston/head looks good.

Now the part that is confusing me is, after I took the cylinder head off and released the compression, the kickstart/piston moves up and down smoothly but when I reinstall the cylinder head the kickstart is stiff again like there is to much compression or something.

If anyone has any insight it would be greatly appreciated!! Cheers!!

take the clutch cover off and see if you can move the clutch basket up/down which means the bearing is shot. Also look for metal "powder" or bits laying around, in which case you need to flush it all out with gasoline.

Yeah, you know those metal thingies, I think they're called tools, you use them to take the cover off and find out what is bad.

Sounds like too much compression, something is moving where it shouldnt causing higher compression ratios, making the bike hard to kick, you could remedy this with a head gasket, or a good compression tester reading to answer the too much theory.
