Start by removing the rear brake lever. After that loosen the rear axle. The 17 mm nut is the only one that will spin, as the axle is essentially a big bolt. Once the axle is relatively loose, begin adjustments using the adjustment nuts on either side of the frame. There should be two separate 10 mm nuts on either side. Tighten the first on until your chain has the appropriate amount of slack (roughly 5/8''-1"). After you have them adjusted to where you want them, make sure both sides are evenly tightened. This will prevent wobbles and excessive tire wear. When you are finished with that, tighten the second 10 mm nut until it hits the first one snugly. Tighten up your axle, then put your rear brake back on. The rear brake will probably require adjustment when you are finished.
snug them don't tighten them
YOU SHOULD NOT HAVE A CHAIN IT SHOULD BE A DRIVESHAFT FROM THE ENGINE TO THE DIFFERENTIAL
it's a 520 o-ring chain at 108 links
Follow the Youtube video.
to put more tension onto the chain you have to loosen off the rear wheel bolt first. then with them loose there is two 10mm ( i think ) nuts at the rear of the swing arm one left and one on the right.. tighten these up to put in more tension. once required tension is reached then tighten wheel bolts again and that's job done. hope this helps.
To tighten the chain on a Honda TRX 450R ATV, first, place the ATV on a level surface and secure it. Loosen the axle nuts on both sides of the rear axle. Then, adjust the chain tension by turning the adjuster bolts located at the rear of the swingarm; turn them evenly to maintain alignment. Finally, check the chain tension and re-tighten the axle nuts to secure the adjustment.
It has a self tensioner, Most often you have to replace the chain it self if it is skipping time or is getting very loose.

how do you tighten a chain on a 150 ATV
The Honda Rebel CBX450C was only built in 1986 & 87.
no that's why they call it a HONDA
Read your owners manual. :) Just kidding. You loosen the rear end clamps, tighten the adjuster screws while you have somebody of equal weight sit on the bike. Tighten until there is approximately 1/2 inch of up and down slack in the chain. Lastly , tighten the rear end bolts. Good luck. :)
