I have a 1991 KX 500 that I just picked up, and need to know what kind of lube I should be running in the bottom end.

Thanks!

Travis

I run 80w Bel Ray gear saver.

I use AMSoil for everything. I am currently reading and looking at the 75wt gear oil that they have out. It is to be high in shear strength and is to be good in wet clutch applications. $13 a quart though.

Bel-Ray gear saver 80wt. mixed 50/50 with ATF.

Ams 20w 50 in every bike ive had.

I am going to run full ATF this weekend without the bel-ray mix.

I've heard a few bad stories about the ATF being run in bikes lately. Any one else? Good oil is cheap in the long run...

Castrol GTX 10W40. It's cheap enough to change after every ride and seems to work quite well.

I ran full atf this weekend with no clutch problems. If you think about what goes on in auto transmission with all the moving parts and gears it should be o.k for a simple gear box and clutch. The bel ray looks and smells just like AFT. My clutch acts up if I use standard 10w-40. The gear saver and the AFT seem to work the same for my clutch with no slipping. I just think AFT should have more shear strength then anything else. I change it after every ride(still using Alum. plates in clutch).

Just update. I have been using ATF now for about the last 20 hours with exl. clutch operation and butter smooth gear shifting. I am using ATF type F which doesn't have all the friction mods. I have spoken with several people out at the track and alot of people are using ATF. I spoke with a local bike tuner that preps. race bike for racers and he using ATF type F. This stuff is less than $1.50 a quart at wal-mart.

How long has ATF been popular with bikes? Like does it have a proven track record?

hughes · « **Reply #11 on:** July 29, 2005, 01:05:33 PM »

Good question. I know of one person that has used it from day one in his YZ250. This bike is 5 years old now. My local bike tuner has been using it for 10+ years. I am going to stick with it and see what happens.

Just keeping this updated. I have about 4 more rides with AFT Type F scents late post. This stuff really works. I encourge you to try it and you can feel the diff. in the shifting. Just my two more .02 cents

I have used spectro clutch saver 10w30 for almost a year, recently the local dealer ran out so I tried spectro 80w gear oil. The 80w seems to downshift into first better at a stop. Keep us posted on the type F ATF because it would be a whole lot cheaper. I change trans oil once a week, which is about ten gallons of trail riding time. KX500 big hit is the best!

It's all about the ATF type F.have been using it on all the bikes i've ever had,no problems.
