Bike chain odd problem
Hello all you wise people who may be able to help me.
I have a Suzuki GSXR 600 and there is something very odd with the chain.
If you measure the slack in the chain and then roll the bike forward it goes tight, ( no seized links checked)
Both sprockets and chain have done around 500 miles and in good condition.
removed the chain checked the sprockets are not bent and refitted,rotated the front and no adverse movement, same at the back.
Refitted the chain, same problem, the only thing I can see is if you look down the length of the chain from the back wheel and rotate it, it looks
slightly bent as it goes around.
Any ideas!

Check the sprockets are in line ( long straight edge or laser ).
Have the spacers for the back wheel been put in the right order/place ?
Is the back wheel in straight according to the adjustment marks ?
Forgive me if I'm teaching you to suck eggs.

The sprockets are slightly eccentric on the shafts so as they turn you will get slack and tight spots, this is quite normal. When adjusting you should
spin the wheel through several revolutions to try to find the tightest and slackest points and make sure that both positions are within the tolerances
given in the manual. When you can no longer manage this it is time to replace the sprockets.

Thanks guy's
I have checked the rear wheel against the markers and measured with a steel rule to make sure it is straight.
What is odd is if you look at the teeth in the rear sprocket as they engage with the chain you can see daylight between the tooth and the inner wall
of the link, if you rotate the wheel it disapears as if the sprocket is buckled, it not as I have taken it off and put it on a flat surface and not
gaps, thus why I think the chain is bent

If the chain is severely bent, I would change it,especially on a bike. If it gets any worse it could cause the back wheel or front sprocket to lock
up, or even the chain to snap. Just my opinion of course.

What are the sprocket teeth like? They wear and get sharp points and eventually turn into hooks if you let them get bad. Are the tensioners equal?

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
