fork oil viscosity FYI

In the latest MXA, it was stated the Kayaba 01, Showa SS-7,and Pro Circuit PC-01 oils are all PRODUCED by the same company and are all 5 wt. They are identical w/ the exception of color. I recall one person saying Kayaba 01 is 1 wt oil.

The article also states you should go no lighter than 5 wt for the lubrication abilities of the oil.

I am presently using 2.5 wt PJ-1 hoping to make my forks more fluid. I guess I am all hosed. :)


'99 WZ/YR (you choose!) with ALL YZ mods, de-octopused, DSP Doug Henry airbox w/ velocity stack, FMF PowerBomb header, Stroker SX-1 silencer, SS front brake line, OEM YZ tank, IMS YZ seat.

Thanks for the imformation, am just going thru my forks as we speak, and was curious what to put back in, besides YAMMY lube. 5 wieght sounds good to me. I can't believe what I took out was 1 wieght, maybe whale blubber, but not 1.

Yamaha 01 is NOT one weight. The OEM stuff in your forks was 5wt.

Yo Trailguy! I just did my forkseals last night, you may recall that I was lubricating my front brakes on the 6-Days ride.

I switched from Bel-Ray to Motul 5wt this time. I love their engine oil (I think you are using Motul as well?), and the fork stuff has been recommended....

That being said, it's probably the same as everything else!! Kind of like Homer touring the Duff factory, and all Duff Dry, Duff Light, and Duff Ice all coming out of the same big vat :)
