I read an article in one or the current magazines where a professional mechanic says to grease all the bolts on your bikes. For the past couple years I have actually been using blue loctite - and the past year or so I have really liked the blue loctite that is solid and comes in the twist up tubes like Chapstick. A few years back I actually tried greasing the threads of some bolts - notably the motor mount bolts on my 99 YZ450F. Unfortunately, before I was close to the recommended torque, the threads in the frame totally stripped out, and I had to end up using Time-serts in the frame. So, I'm concerned about repeating this horror on my new bike (07 450). Also a concern is the tendancy for 4 strokes to vibrate and loosen bolts, which I think would be even worse with grease instead of loctite. What do you guys use - grease or loctite?
