My son was riding over the weekend, and the chain fell off his bike. I was told I need a new sprocket. Does anyone know what size I should buy for a 2006 Polaris Trail blazer 250? Also do I need to buy a new chain too?
Have you used all the adjustment in the tensioner? If your sprockets are ok, you can take a link out of the chain, and back off the tensioner, but I would think about a chain. You can buy entire sets (both sprockets and chain) for pretty cheap, might be the better way to go? How many times do you want to have to screw around with it?
