Hi,

How many quarts of oil with and without oil filter change does it take to perform an oil change?
What store US, and model number oil filter should I use?
The oil tank under my seat suggests 15W50 but reading the forums I realy find people using evrything BUT 15W50, what's the scoop?

Cheers,

PLEASE HELP ME I WOULD BE EVER GRATEFULL!!!!

Use near 3 quarts of Amsoil (best alternative) Syntetiic oil 20W50 for a 4 stroke bike, KN-145 oil filter.

To discharge all the old oil you need to remove the oil screw in the bottom of the motor and and the small tube near the oil screw and let to drain
