With everyone always talking about loose hardware etc loctite seems to be the only thing people mention as a fix.
Nobody has mentioned marker paint.
Being a desert rAcer I use it on my kx and on mu ktm (my long distance dirt bike, like cross country).
Makes it quick and easy to see the status on bolts etc. Motor mount and so on. Quick glance in the pits and your good Togo, or just between rides.
