crank side play
 

hi guys i finally managed to replace the stator casing gasket on my xt600 49r after my ignition problems . while i had the casing off i felt for play on the crank bye grabbing the rotor/flywheel , i can move the crank side to side what seems a lot, i dont have a dial gauge but with a ruler it seems like just short of .25 mm now i know the bearings are c3 type and have side to side play built in but all does not seem well . when i got the bike i took the inspection screw out of the casing to feel for play , 8 years ago and 18000 miles ago bike now has 36000 miles if all is right with speedo and there was side to side play but i dont think it was this bad . the bike runs fine . do the main bearings go on the early kick start models . i need to take off the clutch right hand casing to check the primary drive /crank nut is tight , if it has come undone a little would this give me the movement ? zigzag

hi guys still after a bit of help/input on this one so any early kick start xt600 owners out there with more experance of this or engine builders with know how . bike runs fine . zigzag?c?

Side to side play generally isn't a big problem unless it's very excessive.

It's the up and down play that you should be worried about. That's what 'rod knock' is.
