chain gets tight and loose when it spins

And, as well as the chain and sprockets, check your swing arm bearings.If they are worn, adjusting the chain won't help, and it will wear out rapidly as the swing arm flops back and forth inconsistently.

If your bike is old, and new to you, make sure you inspect the condition of the bearings. You don't want surprises, or to replace the chain when the root of the problem is a loose swing arm.

when the chain does that tight loose stuff it means the rollers are wore and some are broke some are not,thats why its up n down feels like its bent get a good chain first, go by the tensile strength! a stock one will cost more in the long run cause there cheap, you can use stock sprockets though, the chain is what ruins the whole system
cause it will eat up the sprockets, so replace all at the same time, im sure there are a ton on ebay, smaller rear means faster on the highway,and easier on the rpms (1or 2 teeth)

I guess that's the best explanation I can get for it. I've checked both sprockets with a depth gauge and every tooth is the same with no visible wear. They look new. So I should be in good shape with a new chain. I found what claims to be better than stock chain for about 90.00 before shipping. Not very confident on the 530 setup as nobody seems to sell a "kit" to do this and nobody lists any of it for my particular year and model. Anybody know where I might find something in the likes of a "kit" for an '83 750T?

I have an '82 that I noticed is doing the tight loose tight thing today (found this thread using the search!) and this is what you are looking for.

I'm buying one for sure.
Anyone have any comments on the quality of this set?

Actually after reading up more on the differences between 630 and 530 chain, I'm not sure that is the right set for you, but I know that ebayer will have what you need. They have TONS.

I just read this:
"630 chain is 3/4" pitch (or think of it as 6/8"), 530 chain is 5/8" pitch - so the simple conversion in teeth is divide the 630 sprocket teeth count by 5 and multiply by 6.
630 15 tooth front becomes a 530 18 tooth sprocket.
630 35 tooth rear becomes a 530 42 tooth sprocket.
92 link rear chain becomes 110.4 links (rounded to 110)."


out 750T's are 630 15-41t, so I think we'd be looking at a 530 18-49t kit for the stock ratio

I'm not sure if they have already done the conversion or not in the ebay listing so I would email first to be sure, seems like a stupid thing to leave out of an ad though.

Have you checked your rear axle is tight and the wheel bearings ok also?
