[04Ltz40015]

I have a 2004 suzuki ltz400. I dont have a owners manual and need to tighten my chain. How do i do this.

[bleedi kfx 400]

if the z 400 is just like the kfx 400 there is 5 bolts 4 on top and 1 at the back side losen the 4 bolts on top and tighten the back one untill the chain gets tight
