I concurr, the only bolts i would use locktite on are the ones holding your discs of your disc brake systems on. Other than that copperslip them all but be careful as it is carcinogenic, if your posh get a PTFE based grease.

you can get a cheap anti-sieze, it's uh... Bostick.

the stupidest thing about the whole Loctite argument, to me, is, everything i've ever used it on came right off anyway. i've never had a bolt stuck that i had to use heat to release, never had a bolt that was actually "locked" in the threads, and never stripped any threads because of it. i personally think it's completely useless.

I wouldn't recommend rubber mounting the engine, it isn't a comfort cruizer. I would just put up with the vibrations and ride it. You never see motocross engines rubber mounted. Even on on less offroad biased machines like KTM LC4s they don't rubber mount the engine and they are one of the vibeyest engines around. Even ducati road bikes with all there vibes don't rubber mount there engines. rubber will just allow the motor to flex around maybe changing chain tensions etc...

Actually it tends to cause engine mount fasteners to sheer and can lead to fuel foaming problems (you mighta reduced the frame vibration you feel - but ya increased the engine's lol) , as well as the engine tends to cut down/through the rubber after a while - letting the engine twist like you just mentioned

Yeah - rubber mounts are terrible lol, seems like such a good idea...
