gear case oil type
- Thread starter overbore
- Start date
I've been using Bel Ray 75 wt gear oil in my KTM's since, '89, never had a problem. (I run 125's)
I do use Dextron III in the winter, (when it drops below 40 degrees) to help it shift right.
I dunno if I'd use motor oil, it may not work well with the clutches.
Motor oil is designed to cushion between metal parts, (piston bearings, cam, bearings, etc)
Trans oil and 2 smoke oil is designed to cushion gears, but also help with the fiber clutches.
As for your clutch problems.
1. Are they fully engaging, (no play in the cable or master cylinder, (you can take the oil plug out and lookie-see in there)
2.Are the springs cooked??? No pressure/weak pressure against the plates wil cause them to slip.
3. How often do you replace the oil?
If your riding style is "clutch happy" them your clutch life will be short.
Try a heavy duty clutch package if that's the case.

The reason the clutches wear quick(assuming its like the 125) is the alloy plates-they will wear no matter what oil, best to use steel plates instead i hear the CR125 ones fit.
Steel plates polish up and thats why the factory/racers dont use them.Alloy grips an in turn wears out but offer the best performance.I think honda plates fit and they last ages. I know KTM riders / pro team mechanics who say problems with the hydraulic clutch causes the plates to wear fast .

change oil every other ride and after every race my son rides,so thats not it.He is hard on a
clutch with the 200.yes I make sure that its not slipping because of adjustments.Just wanted to
know that regular 10/40 was ok or if anyone else was running it,instead of atf which I have not
had to good a luck with lately.
