I know manuals give info on how often to change gear oil but wondered what the general opinion was on how often it should be changed for those who have or have had these bikes.

Oil is cheap, rebuilds are expensive

I change mine every 4-6 outings, so anything between 20 and 30 hours of riding time...

I was thinking of every 6 so am in the right ballpark. 6 outings takes me to the lower end of the hours category so should be fine if I stick with that rule.

Here's a little hour meter if you really want to know how many hours are on the oil. Enduro friends of mine use them.

about 3 times a year is plenty after the first change which would be after about 3 times out.

3 times a year Eddie? you cant ride much then. Dump the oil after the first ride out from new and I usually change mine every 25 hours at least, oil is cheap but clutches and gears arnt

A friend has commented on the possibility of using a very lightweight oil in the gearbox to aid shifting. Has anyone any experience with this and how does it effect oil changing frequency?

this might sound stupid what oli does every one use (whats the best) ? thank you

PJ1 clutch tuner is nice for me.

But Silkolene and Motul has been fine in the past aswell.
