I hope you guys can steer me in the right direction.
I recently had a Shinko 705 put on the rear of my 18 Adventure Sport. I replaced a worn out 805. Now, whenever I hit exactly 46mph there is a high pitched hum or whining sound. It does not matter what gear I am in or what RPM am doing.
It is not as loud when I am accelerating and the engine is under load. It’s still audible, but not as loud. It is quite loud when decelerating, though. As soon as I hit 46 mph, it sings for a second or two.
It should be noted that the shop that changed the tire for me set the chain tension way too tight. It had about an inch of slack. I set the tension to about 50 mm which is 2 inches. That is the minimum tension to be in spec for the ATAS. I set tension with the bike on the side stand.
My question is whether y’all think I should add a little more slack, or is the Shinko known to behave this way? I wasn’t able to find anything on this.
Next time I will stop being lazy and just change it myself.
