Is my cam chain tensioner manual or auto tention on the fzr400 3tj? if manual, how do you set it?

just want to make sure everything is ok.. no issues to be fair

should be auto. Theres a spring that pushes on it. If it starts to rattle you can help it along with a screwdriver if needs be but it should do it itself!

as taggy said it adjusts it's self
see part number 8 on this list, the little knob on the end is spring loaded on a ratchet type affair and once it's adjusted in it won't come out again unless you take it out and put it back

So basically - if it isn't rattling don't fix it
