Default Loctite Overdose?

I typically use blue loctite on most everything on my bike, but I’ve read that I’m using it too much. Some bolts need anti seize? Looking for some general guidance....Thanks

There are some places where Loctite should not used. For instance, the three small screws that hold the air filter to the air filter studs.

Where'd you read that you're using it too much?

I use blue on about everything. "Can't hurt, might help", and all that. The exceptions are where the FSM specifically says use something else, like red on compensator nuts and lightly oiled threads on head bolts.

Anti sieze? I put some on spark plugs. On axles. Just put some on the threads on my stabilizer links yesterday. I'm sure there are a few other places, but none come to mind at the moment.

I know I am going to catch flak for this, but in general, the smaller the screw the more careful you need to be regarding whether you should put blue loctite on it. The screws holding the air filter to the air filter studs use a T27 Torx wrench. They are small short screws. If you put loctite on them, you may find that you cannot get them loose when you go to change the air filter.

In my experience, for both Loctite and anti-seize is a little dab will do ya. I only use anti-seize if the Service Manual or a part manufacturer directs/recommends its use. YMMV....

The "purple" Loctite is perfect for those types of applications. If in doubt as to what was used or if you meet any resistance, before you try and wrench it and most likely strip the fastener, you can apply a specialty solvent (same stuff used to loosen superglue) or heat (a small torch or soldering iron applied to the fastener) to loosen the Loctite bond. Given time and the orientation of the fastener, either method will allow you loosen even fasteners tightened with the Red high temp/high strength Loctite.

there is a loc-tite designed for smaller bolts...it's either green or purple. You need to READ the container to make sure. But I would not use blue loc-tite in any fastener smaller that 1/4" ….use the smaller gage type if you need it.
My rule for anti-seize is aluminum and steel. If you are screwing steel bolts into aluminum components, I would use anti-seize

Try using lock washers or split ring washers on some of the fasteners that are in contact with heat such as exhaust bolts or other bolts that require anti-seize compound. It's a cheap solution and ensures that the bolt will resist loosening on its own.

Use never seize on exhaust studs.
