Loosen the rear axle nut. Next, loosen the nuts that lock the wheel adjusters and look for the notches that tell you the position of the wheel telative to the bike frame. Move the wheel back a bit until you are sure the chain has the optimal tension. Make sure the wheel is not skewed to either side by looking at the notches on either side. Get a torque wrench to fasten the wheel in place at this point. The chain must have a bit of slack, it should never be totally stretched out. You should have about 1.5 inches of vertical chain movement when you push it up. Clean the chain with WD40 or some thin oil that you then wipe off. Now apply chain lubricant or simply engine oil to the chain. Take a test drive on the bike, then check if the wheel is tightly in place and that the chain has the tension you want.
Well, my 2002 Honda Shadow vlx 600 takes a 525x120 chain.
Once you slack the axle, there should be adjusters to tighten up, just make sure the wheel is even, and torque the axle nut back to spec's.
YOU SHOULD NOT HAVE A CHAIN IT SHOULD BE A DRIVESHAFT FROM THE ENGINE TO THE DIFFERENTIAL
Follow the Youtube video.
my 750 has a 525 122 chain
with a standard 17t front sprocket and a 42t rear sprocket the standard chain size is a 525 ( x-ring or O-ring) 124 link.
The 2005 Shadow Sabre is Shaft Driven
Size 525122 links
120 chain link
I would recommend going to your local Honda dealer or getting on online parts stores and looking for simple chain lube
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.
To tighten the chain on a Honda 3 wheeler, first loosen the rear axle bolts then turn the adjuster nuts clockwise to tighten. Finish by tightening the rear axle bolts.
