Slippery when wet

I have a 93 FZR 1000 with 43,000 miles on it. does anyone have any recommendations on which type of oil would be best for this aging machine? :?: :?:

Oil is Oil, don't matter so long as you change it at regular intervals

[SteveFZR]

Sweet, thanks for the info.

Yes.

Use Castrol GPS 10w/40 next time. I love this stuff, it's even a cool purple color. In comparison to other oils, it has a few more long chain additives, this makes it time-consuming to re-fill using a funnel, but the advantages are obvious.

For increased ponies, I use Castrol R4 on the track. Be careful with the R4; it is designed for increased power, thus, less viscus in certain conditions. This oil gets the increased power from less drag on the engine crank, but will need to change it more frequently.

I always liked the flavor of Mobil 1 , keeps your stools regular too

I used to use ATF in the gearbox of my 2-stroke racebikes.
funny how they recommended GEAR OIL!
was good for a couple extra ponies...

auto tranys got the same plates in um as the clutch that y some new cars use atf in there standrds as it depends on the bearings

[TLRMan]

Beet!
You hit the nail right on the head!
The bearings didn't suffer at all.
But you gotta remember..we were doing this in the 70's....
Ceramic bearings were just coming into the picture too, but we had to build them by hand...This was happening in the 80's.
Those bearing balls didn't skid as bad as steel ones, and because they were lighter, turned up quicker...Going fast wasn't one big change, it was a lot of small ones that added up.
