What year clutch basket will fit my 1990 yz 80

you will have to buy the correct item.These are not interchangeable.

Check your clutch basket for grooves. if so you will need to replace basket.

I’m happy to assist further over the phone at https://www.6ya.com/expert/michael_18b4936ebf017b21

if you file the grooves, the plates will move about and likely break the basket, as the filing is not likely to be exactly even it will cause poor clutch opperation. sorry i dont know what years will fit but they dont change that sort of part each year, the bike breakers\wreckers may know that one.

It's one of the few that has a diagram.
Not sure what you mean by anti-rattle? The springs are for the pressure plate, and allow the clutch to grab, so you can go.

the only way to tell is to match them up with out knowing exactly what year they both are its hard to tell but the change every couple of years

Hey Ryan! Long time since hearing from you.

When you say "main clutch casing" do you mean the right side cover for the gearbox or do you mean the primary driven gear (AKA "clutch basket") that the clutch boss (AKA "clutch hub") and all the clutch plates fit into?

If you mean the right outer casing > they are slightly different, '97 pn 4JY-15431-10-00 and 2001 pn 4JY-15431-12-00. The entire clutch is the same from 1997 through 2001.

Hey Ryan! Google " motorcycle tires " and you should be able to find the 120/80/19 tires. Call the dealer for additional sizes that will fit.

Please rate this solution. Thanks!

P.S. > Did you ever get the clutch fixed?
