Std exhaust silencer weight

You're right there, i only really have to consider adjusting the chain when the rear wheel needs removing, otherwise it simply doesn't get touched other than cleaning or lubing.
Again another thing i've noticed about using engine oil on it is that i don't particularly even find it necessary to clean the chain so often in comparison to when i used to use the chain lube. It doesn't get anywhere near as dirty or gritty as before, which can only be a bonus.
