Stretched chain or sprocket is out of round. If the tire was bound then id suspect a stretched chain.

you dont take care of your chain. replace the chain and sprockets and use lube more often. if you dont, it will get worse and worse and will lead to some real damage.

David,
You may need to replace the rear sprocket as well. Read this: http://www.ninjette.org/wiki/Sprocke..._Chain_Options

Normally, when the chain wears out and suffers some elongation, it damages the original shape of the teeth of the front and rear sprockets.
If you have lubricated your chain that well, then your problem may be different and the chain and sprockets may be still good. I would inspect the chain link by link trying to find some kink, corrosion or frozen link. Do you have the manual? The manual shows how to measure the chain in order to verify if its elongation has reached the specified limit or not: Hang a 20 lbs weight from the midpoint of the lower chain. Measure the distance of 20 links (or 21 pins). Repeat the measurement until the full length of the chain is covered. If any of the distances is more than 12.7 inches, the chain should be replaced. Before measuring the slack of the chain, you should find that point at which the chain gets more tension and you should provide the proper slack only for that position of the rear wheel. In other words: the chain should have a minimum slack of 1.5" for any position of the chain around the sprockets. Otherwise, the chain, sprockets and bearings will be overloaded when the bike squats in normal operation, leading to premature wear or failure of those parts. Now, if after completing that adjustment and turning the wheel around and repeating measurements, the measured maximum slack is way too big (something around 2.5"), then you have a problem. For sliding the wheel back and forth and for any alignment, the bolts of the torque link should be loose, besides the axle nut.

How much is too loose?
If it happens for each turn of the tire, the rear sprocket is not perfectly round anymore. If it happens several times for each turn of the tire, the front sprocket or the shaft are the problem. If it happens after the tire is rotated more than one time, the problem may be an uneven elongation of the chain.

the tight spot ... only happens one time on the chain as it goes around the metel to metal sound comes from the front spocket...when that part of the chain get to it..
as long as it not on that one spot everything seems to be fine... as long as i adjust for chain slack when it's not on that tight spot and just for the sake of asking how hard.. to replace and find to buy is the shaft? |

It seems that the problem is only in a section of the chain then.
In order to replace the shaft, the whole engine has to be open, but according to your description, that is not the problem. I would measure the 21 pins as explained above. Then, if the chain is withing acceptable specs, I would clean that section with kerosene and will lubricate it with automatic transmission fluid, just in case it is repairable.

It is the best preserver of O-rings and being so light, it stays on the chain. It also keeps the chain clean and Florida sand and road debris don't stick to it. Copied from http://en.wikipedia.org/wiki/Automat...smission_fluid "The fluid is a highly specialized oil optimized for the special requirements of a transmission, such as valve operation, brake band friction and the torque converter as well as gear lubrication. ATF is also used as a hydraulic fluid in some power assisted steering systems, as a lubricant in some 4WD transfer cases, and in some modern manual transmissions."

The video showed three important things to me: 1) The chain is frozen in some sections (lack of lubrication, rust, etc.). Gasoline is not good for cleaning; use a plastic brush and kerosene, WD-40, ATF or even hot oil. 2) The master link is a clip type: If the chain is O-ring type, that link is dangerous, unless you wrap some thin safety wire around the clip in order to prevent it to open up while riding. If the chain is non-O-ring type, it is OK, but the wax type lubricants are not good for that type of chain; they need hot thin oil. 3) The rear sprocket has shark teeth. Those will damage any new chain. The damage was done by the elongation of this or a previous chain. Did you measure this chain yet? You can flip the sprocket or buy a new one if you replace the chain. Check this link: http://www.dansmc.com/rearchain.htm
