So i changed oil on my dtre, and when i started it up it was just fine. Next time i started it, it made a weird sound, it sounds like the clutch, the bike vibrates a lot when reving, when shifting gears it seems like the clutch doesn't want to let go.
The oil i've used is SAE 10w40, i read in the manual that the right one is 10w30. Does this have any effect on the clutch?
This problem werent there before oil change.

No the oil is not specially made for motorbikes, so that might be the cause?

@bananper I’d lay my bets on it I mean you need to change it anyway so change it and if it fixes it then that’s a bonus motorbike clutches hate car oil

@declan Not true, I use Castrol GTX 5w-30 semi synthetic engine oil on my DT no problems.
Definitely does not like Magnetec though. Having ran that for a week or so, the clutch plates survived and went on to do many more miles.

You need oil that's JASO MA or MA2 spec oil, you won't go wrong with that.
Believe or not some diesel engine oils actually meet that spec, a lot of DR650 forum members ran it in their bikes, but I never tried it. -

@Calum @declan @finnerz89 so here's a video on whats happening. Im not sure if you can hear it, but the whole bike is vibrating, espesially the chain and the rear half of the bike

changed to the correct oil before the video was filmed, exactly the same problem.

The thing is we can't really see how much it is vibrating, personally I don't think it is much of a problem. All of my 2-stroke off-road bikes have vibrated, most notably my GasGas. After 10 minutes of full throttle you won't be able to feel your feet. How many miles has that engine got? If your bike is vibrating more than you believe it needs to, it would make me think the problem is a bigger one. I'd check the engine mounts, however unlikely it is.

@minia around 24k, the engine has been rebuilt by an mc shop when the previous owner had it. It has never been shaking like this, just came out of nowhere

@Calum @declan @finnerz89 @Minia
Looks like i've found the problem, only thing is that that the clutch basket is loose and i dont think its supposed to be that way

@bananper Have to check the manual I'm afraid. I'd image it's pretty high and you will need to lock off the crankshaft to do it.

@Bananper A loose clutch basket seems like a good culprit, but you need to know why it is loose. Or what made it loose. Well anyway, if you're taking it to a local shop they should be able to find and fix the problem. Afterall, the DT engine is pretty easy to work with.
