Possible Damage?

Changed the rear tire the other day on my 954 and adjusted the slack in the chain, was a lil too loose. Went for a 30 mile ride and half way through I heard a knock, then I felt it in the pegs. Upon pulling over I noticed that any slack in the chain was pretty much gonzo. I went straight home and got the bike on the stand. Upon spinning the rear wheel, I noticed it getting hung up at one point in the rotation, and it seems to be coming from the front sprocket area.

A) Did I possibly bend the input shaft???

B) Really not sure why the chain tightened up, I've changed the tire many times.

Going to take an in depth look at it when I get home tonight.

Thanks

The "hanging up" you feel - do you mean the chain is too tight at this point?
You must adjust the chain to have the required slack at its tightest point. Try adjusting again at its tightest point and see if it's still a problem.

Most likely, almost seems like something is rubbing behind the front sprocket guard.

OK, never realized the chain would be tighter at certain points of the rotation, must have just gotten lucky till now. Is that b/c of the master link?

Thanks

No, it's because it's impossible to have 108 links all wear exactly the same amount :-)

Take the rim off and inspect the wheel bearings. Wrap your finger around the inside of them and spin them. If you feel any grinding at all replace the faulty bearing.

You sure the wheel is centered, did you tighten the axle retaining bolts to specification?

Checked the bearings, seem fine. Pretty sure I just overtightened the chain.

If by tightened to spec you mean hand tightened, followed by a few light hits from the impact, then yes. Happen to know the spec off hand?

You could also try rolling that axle on a piece of glass to see if it's bent.

I don't have the specs for your year bike, but I'm sure Blade does. But it's supposed to be 69ft-lbs for the axle nuts on mine.

Notice it says to place it on it's side stand when adjusting the slack, not a lift or jack.
