On a motorcycle loctite is your friend. I also used just a little line of sticky grease around the back of the flange on the air filter where it comes in contact with the bike to make sure one get’s a good air seal.The service manual makes no mention of using blue loctite on the pinch bolts.
I agree. Moisture ingress into pinch screw threads can be a problem. Most thread sealants/lubricants will cause thread distortion at final torque, unless the final torque value is reduced. But this reduces the "pinch" effect in the end.....Mine were over torqued from the factory, but there is another potential problem with these fasteners and that is the possibility of moisture intrusion at the split in the clamp leading to corrosion on the threads.
Some Jap bike manufacturers recommend some form of thread sealer on these fastners, and also on any through bolt like caliper bolts where there is the prospect of moisture intrusion from the far end.
Some suggest a non hardening gasket compound, or a the lowest strength locking compound, but remember that torque values are given for clean and dry threads UON , so if you use antisieze or grease the torque values should be reduced 15/25%.
Loctite normally does not need any reduction, don't know about the other brands---!
