If you are putting together just about anything on your bike you are going to need some form of threadlocker.. Loctite is easily accessible and performs excellent for me... These tubes would be perfect if I could get a bigger size.
Back during my old two-stroke riding days, that diabolically delicious dirt bike would vibrate and raddle every sort of bolt and screw out of every place you could think of. Once, the power valve cover had three of the four bolts rattle out and i went on a 2 hour ride though the sand dunes like that until i noticed it. I had never even opened/modified the power valve.
I lost so many bolts and screws... until i started using loctite on everything. A little dab will do ya holds true, and now i use it every single time i'm swapping bolts on my bike.
The only i don't use it are for areas where i need frequent access; oil plug, air box, etc.. Othwerise, if the bolt comes out for any reason, it's going back in with a dab of loctite.
It adds just enough stick that you won't need a breaker bar to get it loose (as long as your within torque specs), but that extra effort you have to exert gives me all the peace of mind i need to know that i won't lose any random bolts and screws because of the vibration of the engine.
This was recommended by a friend so that the bolts don't back out. I don't use it on commonly used bolts like the plastics, but I used it on bolts that I don't intend on removing often, like certain bolts on my new radiator guard and the bolts on my new skid plate.
