01wr250f holds 1.6L
i know i owned/raced a 01yz250f for 5 years. many of my oci's are from it. the others are from its replacement an 06yz250f.

i know the 01-13 motor inside and out.

i've done 72 uoa's on it. starting at $20 and now $25 you can figure out how much i've spent on just that doing uoa's.

i've tested so many oils (but a far cry from all of them) to prove my signature that i dont need to test them all.

mobil special replace superflo - but i've not tested it.

extremely hard to beat Shell Rotella T 15w40 white jug.
but any of the hdeo's will do.
