i just bought myself a 2002 yz 85 and i dont know what i am supposed to change at the starting of each year.[img]i/expressions/face-icon-small-confused.gif[/img]

 

well its a two-stroke so you want to change the oil alot, and plugs.

 

every year check ur reeds,clean ur carb, check ur fork seals,grease ur rear shock linkage bearings and ur steering stem, check ur brake pads too, they tend to wear fast in the mud, save the hassle of a dirty bike and keep it clean alot too. change ur oil alot and check ur plugs like garrett5462 said. also to get better handling set ur susp. sag.

 

also you could flush your coolant and add new coolant mostly everything else has been said already

 

coolant is sugg. every 2 years but every year is fine
