So here is the deal I have a new 520 chain on my 04' had it for a bout 6 months now. I do all the regular maintenance and upkeep myself. Recently over the past month and a half I have found that my chain slacker than usual and mean extremely loose. So I checked everything out and the sprockets and chain appeared in good shape.

So I threw it up on the stands and tighten everything up. Only to find that a week later I had the same issue. :retard: So I did this constantly for roughly 3 weeks. I am starting to get pissed. Because its becoming a hindrance as the bike just does not function properly with all the slack. Any ideas as to what the issue could be?

should I possibly look as the front sprocket for worn teeth? I did not check that. Could that be a reason?

Incorrectly adjusted chains will wear out pretty quick, same with cheap chains.

ha paid 180 for the chain... so it not cheap. But dang perhaps improper tightening. But the odd thing is that when I did tighten it, the chain met proper specs. Is there any particular way I could look at the chain for ware? If so what are the tell signs? THX

Cheap as in low quality, not low price.

The main way to tell if a chain is worn is if it excessively stretches, like what your problem is. Maybe you're not adjusting it right or the rear wheel is moving from not being tight.

Well I have noticed that the rear is moved in a tad bit towards the front. I'll give it a look over after work and see what the issue is. Thx. I thought it was perhaps my chain tension adjusters. Ill just look at it. Thx.

I would make sure that the axle block screws are tight and touch the blocks and then make sure you have the correct torque on the axle nut. 96lbs I believe. Will check owners man when get home unless you have one...

When the chain starts to go it will keep going... If you over tightened it at any stage you will have caused it to stretch excessively and that will be the end of it. Good way to check is to measure the distance between the centre of the pins, for a 520 chain the distance is 15.875mm, measure it over 20 pins and it should measure 317.5mm. The difference between that value and what you actually measure will tell you how worn the chain is. If it measures 323mm or more it is probably in need of replacement.
