Chain has a tight spot?

[Wag]

Got home from a ride today and as is my habit, I raised the rear and went to spray down the chain with wax. As I did so, I noticed that at one point in the rotation of the wheel, it became somewhat difficult to turn.

I took the time to pay attention and it's just as this one section of the chain gets to the same place in its rotation. Where it gets stiff to move, the chain gets VERY tight. The rest of the way around, the chain is actually quite loose and has no problem.

Any ideas on this? I'm a little hesitant to ride it now because of this. I doubt it's either of the sprockets but I'm going to have to inspect the front one.

Now I'm paranoid.

How many miles on that chain

Alignment possibly? No mechanic, just an ex-tire guru. If the sprocket is not lined up well it could be tighter when it is at it's tightest point of the rotation. How are the teeth on the sprocket? Any broken or noticably worn down?

I would put the bike up on stands, start it up, let the clutch out at idle in first and see if the wheel looks to be off rotation or if you see anything else noticable.

Is it the chain links that get tight, like not wanting to wrap around the sproket? Might be a burr on the inside roller of the chain.
If its at different spots on the chain, but same spot sproket wise, more likely a alignment issue.

Thats a bad chain,get a new one asap.There are busted rollers somewhere on there.

I'm going to tear into it tomorrow and see what the hell's going on.

That tight spot is a typical result of excessive Busa enjoyment such as wheelies and launching. Until you change the chain, adjust your chain at the tightest spot.

He doesn't do wheelies or LAUNCH

He does ride aggressively...and the BUS does have plenty of torque

Checked the records and the chain has 15,000 miles on it.

The problem is at the master link as it hits the front sprocket. I suspect the problem is the chain/master link, however, I'm going to pull the cover off the side of the engine and check the sprocket and see just HOW it's wrapping around it.

I won't be riding until this problem is fixed. End of story. Well, until I get it fixed.

--Wag--

P.S. While it's down, I'm going to do the rear suspension, too.

15K and it has a tight spot...you could clean it REALLY well and lube it, if the kink is gone after that you're GTG.

It would be BEST to just replace the chain and sprokets

 

[Wag]

Just cleaned it and lubed it and the spot it still there. You're probably right, though. New chain and sprockets. I'll know for sure tomorrow.

New chain Bro

 

[Charlesbusa]

How'd the front sproket look??

That was the first to go on my bike before the rear sproket and the chain.

 

[Rhythm]

15,000 miles  

.  Just replace the F/R sprocket along with a new chain.

Harbor frieght tools has a cheap electric impact wrench that will bust the front sprocket nut loose in a .5 sec.  Dont ask how I know ! LOL

Forgot to update.

Pulled the chain and inspected sprockets and chain. Sprockets look just fine.

A little red rust colored stuff under the master which is generally what I look for when replacing a chain. Also, several links are rather stiff.

Oh, turns out this is an O-ring chain, not an X-ring chain which is what I had thought I was buying when I had it installed by the dealer many moons ago. At this point, however, I'm in a different state and I doubt I could find the receipt easily so what the hell? Oh, well. At least now that I know it's O-ring, I'm actually impressed it has lasted this long.

Chain is going to be replaced. I'll keep the sprockets for now. They're looking juuuuuuust fine.
