Chain Tightening and Loosening

I bought this bike theft recovery and the chain has set up a while on it. However when you roll it or ride it the chain loosens then gets super tight and then loosens again. I ordered a new chain thinking hopefully its just a couple of frozen links binding it as it goes over the sprocket. Any ideas out there? If sprayed it down with wd and lubed it up seems to help a bit.

PS I ordered the chain but it hasnt come in yet so I dont know if thats going to fix the problem.

If the chain is that knackered you should fit new sprockets too.

If the chain is that knackered you should fit new sprockets too. exactly right

Thanks yea I order sprockets as well. Any possibility it could be a bent drive shaft? It has no problems shifting etc... doesnt jump out of gear or any other issues.

I wouldnt think it was the shaft ,by the sounds of it, it is prob just where the bike has been left or stored for a while without any lube on the chain. They will dry up and that is when you get tight spots. New chain and sprockets should cure it for you....:thumbup

Thanks im thinking thats all it as well. I'll repost the the results after I mount the new chain and sprockets next week. Thanks everybody.

If its been sitting that long, Id suggest replacing your cushes too. Theyre all of about 4.00 each.

I had that problem because the master clip was to tight
