Re: Thread lock your bolts!!
The only thing I use thread locker on is bike parts. Fenders, chain guards and small fasteners, never on the engine. Tighten them once then check after the engine has reached operating temperature a couple of times. I've never had an engine fastener loosen. And I've accrued a lot of miles on my bikes. Use a torque wrench and don't overtighten things. Damaged threads will not hold and overtightening fasteners will damage the threads. Then you'll need a thread locker to keep things together.
If you feel a thread locker is necessary don't use the red stuff or you'll never get things apart without heat if you don't want the aluminum threads to come out with the steel fasteners.
Take some time and read the labels on the product you plan to use.
