Teddydanson Report post Posted March 27, 2020 Hi guys. How do I know what chain to get to replace my old one? Are they all the same length? It’s a 1999 txt 280 ive cleaned the chain but it’s very dirty and full of gunk do I measure? Count links or are they all the same Quote Share this post Link to post Share on other sites
sherco70 Report post Posted March 27, 2020 Wash it out with kerosene and dry before relube. Do a Google search for measuring wear will best tell you how to check wear. Quote Share this post Link to post Share on other sites
b40rt Report post Posted March 27, 2020 (edited) As above, refit it and tension as per spec. Then looking at the rear sprocket, at the point furthest back, pull it away from the sprocket, if there is any significance movement it probably needs replacing. What condition are you sprockets in ?

misscrabstick Report post Posted March 27, 2020 (edited) When you buy a chain you have to pick one of sufficient length to fit your bike, often you will need to remove some links to tailor it to your machine, this is done with a grinder usually. You will probably want a 520 by however many links yours is, you may well have to buy longer and cut it down as mentioned.
