    You sure you fried it ?
    Bill Cairns had his clutch pressure plate nut back off and it gave the same symptom. He torqued it (and I think he might have used some thread locker) and voila ! good as new. He did a you tube video about it.

    Yeah I'm hoping that's all it is. What was weird was is happened suddenly.

    There have been a couple of UK bikes that have "lost" their clutch through the centre nut loosening , mine was checked at the first service and "is not an effected VIN" .

    Does the oil stink? I have never cooked one in some tough conditions. Have done a few tough tracks on my himma, but never really needed to slip it hard, I only have adjusted it once in 6,000km. I hope it's just the nut.

    My bike was one that had to have the washer put on the clutch, so maybe it's just that.

    Yes, this may be the same problem that Bill in the UK had. I watched his Youtube... It seems that there is a steel tab washer under a nut that had not been formed over against the nut. This allowed the nut to back off and then the clutch would not function properly. I could not find where exactly this nut is. It might be in the actuator which is actually mounted in the right hand side cover... Do check this out. It may be that simple!

    Motul 5100 is JASO MA2 rated for catalytic converter equipped bikes!

    I am not recommending Amazon, but they have the best price that I have found if you have PRIME. About $39 for a 4 liter jug...

    Rode it home. Oil smells well, like oil. Betting it's the nut

    These are burned clutch plates. After around 5000km.

    Daily driven but mostly road. I don't ride hard and I don't trail. Too early for burned clutch. Not a clutch rider also. Claimed as warranty. Philippines. [​IMG][​IMG]

    Is that chain driven apparatus the counter-balancer? I thought it was gear-driven.

    Looks like a oil pump to me.

    Yep , the oil pump with a slack chain like on some Hondas ! Interesting to see that there does look like a support for a kickstart shaft in there , shame it didn't get one .....

    The clutch mystery solved. Apparently my bike was built on a Monday. Someone forgot to tighten down the pressure plate. Also it looks like the plates were assembled dry. So soaked the plates in oil and tightened down 6 bolts reassemble and it's better than it was new, much better.

    Incredibly easy to work on, built like a brick s**t house, and fun to ride. I love it.

    Just a photo of the counterbalancer gear where it meshes up with the crankshaft gear. This is inside the main case so you cannot see it just by taking off the cover over the clutch on the right hand side.

    OK, so the chain and sprockets shown in the pic with the clutch removed is for the oil pump?

    That is correct!

    This photo is not a Himalayan counterbalancer shaft but it looks about the same...
    The Himalayan shaft is longer but you get the idea of how it works...

    Thanks JBeK. Any idea how reliable chain-driven oil pumps are?

    Motorcycles in the past have used both chains and gears to transmit power from the crankshaft to the oil pump. Both methods have proved to be very reliable because there is so little load to drive. As for the pump itself, it appears that Enfield is using the fairly standard trochoidal oil pump which has proven to be very reliable in other brand applications. I did read that the early BS-3 bikes from 2016 did have a few oil pump failures, but I am sure that it was not related to the drive chain and I would bet that it was addressed with the 36 improvements which were applied to the BS-4 model.

    This is not a Himalayan Pump - just shown for illustration purposes!
