G'day inmates, This may be a little confusing so let me explain. Changed my chain and sprockets about 10,000km ago with this set: Steel Sprockets & O-RING Chain OEM Gearing Ratio: 17:41 (Front/Rear Sprockets) OEM Chain Size: 525x120 (Master Link included with chain) Disappointingly, the chain has stretched unevenly. It makes it almost impossible to adjust correctly and feel I should just change it out. I certainly won't be using WPS chains again. After only 10,000km the sprockets are still in decent shape. Hardly any sign of wear. What I'd like to do is change the chain with something cheap until I eventually change out the chain/sprockets together with something better. Ebay has one with the following specs: Motorcycle O-Ring 520H Golden 116L chain universal new Brand New Aftermarket Reliable High quality O-RING chain Style: 520H-O Links:: 116 Compatibility: universal Color: Golden Heavy-duty tensile strength Hi-tech heat treated alloy steel Pre-stretched and anti-fatigue Mesh belt conveyor fumace use for roller and bush solid rollers Pre-stressing chain 20000 kilometers guaranteed Under iso 9001:2000 quality management certificate Quantity： 1 pcs My questions to you are, will this chain fit my sprockets? Does it matter my current chain is 525 and this one is 520? Is it a lot more work fitting an endless chain? (the new one is) Can I do this at home? I have limited tools. Appreciate the help!
