ATF as Gear Lube
shiggins37:
I joined the ATF club last week. Man it was nice spending $1.50 instead of $10. Call me cheap :) Hope it works well as I bought my bike used and have no idea how old the clutch is.

How long between oil changes would you guys suggest with the ATF :? I don't imagine it comes out much darker than when it goes in, so I know that won't be a good indicator for how often to change it.

My trany is a very expensive and trustworthy partner in my life. I don't feel the need to go experimenting with it. I can't recall ever losing a race and saying, d**n it if only I had different tranny oil. I have conciderd using mobile one full synthetic gear oil like you would put in the rear diff of a car or truck but I'm not sure if it would be clutch compatible.I havn't even done the research It was one of those passing thoughts.

Yours is the only post in here I've found referencing 80 or 85w oil in the box. I was sold a quart or two of Bel-Ray 85w "gear-saver" oil as the "kind" for the KX5 box.
Any opinions on using this thick oil? I am going to try it this weekend.

The good thing about ATF is that its cheap and its not a big hit in the wallet every time you have to buy a quart so you can change it as much as you want. I would change it at least every 2 to 3 rides like I do with ANY gear oil in my bike but with the price of ATF I like to change it every other ride and sometimes even every ride.

Martin,
The gear oil you have is not the same as 80-90 diff lube. I will try to find a legit explanation and post up.
It will appear to be the viscosity of atf or 10-40... Please stand by... :-)

when talking about "gear oil" they use different standards so a 80W gear oil ins not like a 80W motor oil ("ATF is in SAE motor viscosity) equivalent to a 10W20 oil. 80W gear oil (AGMA scale, ) translates into a 40W (10W-40 or 20W-40) SAE motor oil.") The Bel-Ray isn't much thicker than ATF.
