Surprised nobody has mentioned this yet but when tightening your rear axle, put a round object like a screw driver in between the chain and sprocket, roll the wheel so it tightens the chain against the axle blocks, and then tighten the axle nut to the correct torque.
Tip 2: De-glossing your brake pads and rotors. Take a piece of 150 grit sand paper and sand away by hand. Then spray off with brake cleaner and wallah fresh pad and disc surface ready to be glossed over again. (this was just publisged in motor cyclist mag but i have been doing it for years and it works great and its free).
Tip 3: Check your oil, check your air pressure, check your coolant/radiator fluid, check your attitude before you ride and during your ride! Get home safe and sound!
