anyone know when i should change the gear oil and the coolant on my bike???? and about how much times involed?

coolant you should do every 2 yrs or so.... its real easy and cheap too.

if you mean motor oil, I change mine every 3K miles,

Yea oil at 3k miles...

Coolent depends on your climant. like for me, I change my coolent 2 times a year. Once in the spring, and once in the fall... I change it due to the fact that in the winter out here I have to worry about the freeze. In the summer it gets up to like 110 outside.

i change my oil every 3000-4000km's and coolant normally once to twice a year..
