How do you Tighten chain on a 1985 suzuki 250 quad runner?

Answer 1

That should be in the manual, if you don't have that if I remember right you have to pop off the chain cover and loosen the bolts behind the sprocket then you loosen those two loops on the back of the axle and rotate them in opposite directions to tighten the chain. If that doesn't work you can use a chain, jack, and a truck bumper to apply tension to the axles with those bolts loose until the chain is tight , then retighten the bolts to hold it in that position.
