I think the real question here is, why would you?
Yamalube Trans Oil. You should be able to get it at your local Yamaha dealer. ROCKETMAN
4ozs to 1 gallon
Yes it will all yz125"s are the same from 96-2001 hope this helps :)
A slight change in the body style is not it. The 2001 bike was a great bike with a 6 speed gearbox and a very useable powerband. The 2002 was a 5 speed that didn't work with the yz 125s power and would bog and acceleration was alot slower. Those are the major changes that make the 2002-2004 yz125s alot worse bike then 96-01 and 05-now.
For a 2001 Yamaha YZ125, it's recommended to use 10-weight fork oil. The capacity for each fork leg is approximately 400cc, but it's essential to check the owner's manual for specific measurements and settings, as they can vary slightly. Ensure to replace the oil regularly to maintain optimal suspension performance.
It all depends on your locations.... take your stock settings and run the bike from there.... if your real high in altitude try taking your jets down a size and go from there
