What is the best advice for a rider doing their own maintenance to make sure they don’t strip their oil drain plug or over-tighten their axle nut?

Answer:  “Get a torque wrench & a service manual. Don’t guess. It will save you money in the long run. Most of these guys think ‘tighter’ is better, but these engine cases are aluminum. You keep cranking on that drain plug until it ‘feels’ tight, and you’re going to pull the threads right out of the block. Now your $30 oil change just became a $500 repair in my shop. Look up the spec, click the wrench, and walk away. Don’t second guess torque spec’s that a team of engineers who designed your bike came up with – they are almost always right.
