Monstercraftsman makes chain tensioners
Jon @ Monstercraftsman’s makes chain tensioners to eliminate all chain whip, chain noise and vibration. I am happy to have him on board at xs650chopper as a new advertiser. I give props to any entrepreneur who has the balls to step out on their own.
These chain tensioners are very versatile in that you can either weld them directly to your frame permanently or can also be bolted on. They feature a sprocket with sealed bearings and a hand wrapped stainless steel torsion spring. The nuts and washers are all stainless as well.
The Yamaha XS650 use a 530 (#50) type Rear Drive Chain. The “Bolt on” or “Weld On” tensioners can be placed in virtually any location in your drive line and fits 530 Chains (Standard) 520, 525, and 630 or the Powell Peralta Skateboard Wheel Universal to any chain size!
