Tightening Chain on 85 250R

I am trying to keep the chain from falling off my 1985 Honda 250ATCR. I believe there is a way to tighten. Can someone help? thx <font color="blue"> </font>

Re: Tightening Chain on 85 250R

I'm not sure about the swingarm on the '85 250R, but if it's the same as the '86 and newer 250R 3 wheeler and quads you loosen the pinch bolts on the very back of the swingarm, then rotate the rear axle bearing carrier (it should have either round holes or square slots on the sprocket side of the bearing carrier) until the chain is where you want it. I have found the best way to adjust the chain on my '88R is to cinch the rear suspension down as tight as possible on a trailer, or have somebody heavy sit on the rear grab bar, then adjust it so there is just a very small amount of slack to keep it from binding when I land from a jump. On my R the chain is tightest when the suspension is fully compressed. Hope this helps, good luck.

The 85 3 wheeler has a spanner wrench that is supposed to be used to loosen and tight the chain. You can use something else but be careful not to bend the tabs on the adjuster (if you use a hammer).
