    I’m reading me and obviously I’m not very clear. Synthetic oil was in the bike since I got it last summer. I changed oil saturday for Rotella and starter slipped on monday morning. Can it be related? I mean Rotella is for sure thicker at cold temp than synthetic stuff?

    I always use motorcycle specific semi synthetic, the oil companies add additives for wet clutch and trans gears. What weight did you use? 10-40 should flow good cold rotella or otherwise. I'd change it out, sounds much cheaper than opening it up.

    I'd do a fluid change and leave the filter then see how it runs.

    :hello: Hard to say. At this point most likely sooner than later it will need replaced. I've been told once you go to full syn oil that you shouldn't go back to conventional oil.

    Straight from Pennzoil:
    "Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths aboutsynthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic andconventional oils."

    I just give a call to a local Kawasaki dealer. The oneway clutch assembly part number 13193-1052 is discontinued... :icon_scratch:

    What should I do?

    Buy a rebuild kit available from various source for about 50$?

    Buy a starter clutch of another model? I think the model from the ZL1000 is also discontinued. Do you know of any other part number than can ben a drop in?

    Try a quick oil change and see if the symptoms persist since it started with your oil change.

    If an oil change still doesn't fix the problem, the internal parts are still available for rebuilding; pins, springs and rollers.

    :hello: Go to page 2 of this post. Everything that you need to know is explained. Do not buy a rebuild kit until you inspect the outer housing of the stater clutch for cracks.

    I did an oïl and filter change this morning. I went back to full synthetic 10W40. I took a ride to settle it and now everything is going just fine. There's absolutely no delay or hesitation. A push the start button and the starter makes the engine running.

    I kept the almost new Rotella, it'll go in the lawnmower...

    Your trans gears will thank you too. Hope you have no more issues with it!

    :hello: Did you use motorcycle grade oil. Most automotive oils have properties that over time will deteriorate a bikes clutch fiber plates.

    Yes, I used a brand called Liqui Moly in 10W40 grade. It's meets JASO MA2 spécifications. The starter clutch obvioulsy have a problem because it don't works properly with mineral oïl. But instead of a 2 days rush summer repair, I'll do it during the winter... ;)

    Little update on this post. May be it'll help a few. Since I went back to synthetic oil, the starter clutch is doing his job without a hitch.
