    So, it's my wife's bike, bought new in 2009'.
    Changed the oil today, and the plastic dipstick threads are cross threaded and it won't go back into the engine.
    With the exception of the first couple oil changes on this bike over a decade ago, nobody's touched this bike but me.
    So, although I've been turning wrenches on motos and vehicles for over 40 years, I guess I screwed it up on the last oil change. Weird.

    Question is; Is this a common issue on these 800 twins?

    I also have a 2015 F800GSA without this issue.
    I'll be filing and cleaning up the plastic threads, or ordering a new dipstick if that doesn't work.

    They seem fairly robust - - not easy to damage. Hard to believe you wouldn’t have noticed it happening.

    Maybe somebody tampered with it while parked somewhere?

    Yeah, the kid rode it occasionally and maybe he checked the oil to help out his Pops.
    But I can't imagine this much of a F up.

    Never had a crosshead issue. My first one bent out of shape at the bottom. Replaced it with a metal one and never had an issue since.

    Thank you...
    That's interesting. I'm beginning to think either mine is somehow mishaped somehow with age, or that there's something in the case threads that I can't see. The stick threads are probably warped like yours was.

    It'll thread down about 1 1/2 turns then hits a 'wall ' and starts to cross thread.

    Where do I find a metal one?

    Touratech doesn't seem to carry one anymore.

    I'll measure the stick threads, and then the case thread peaks with a caliper and see where it falls. I'm thinking that overtightening has stretched the upper threads.

    Otherwise look on ebay for à cheap used one. They go for like 5 bucks over here.

    So, today, I start the bike, 2009 F650GS with 5,100 miles on the odometer, and it lurches and dies while sitting in neutral and shifting into gear with the clutch lever pulled.
    I rode this bike 3 weeks ago without issue.

    It's as though the clutch plates are stuck together.

    I tried rocking the bike back and forth with the engine off, clutch pulled, in First gear. That just turns the engine. Can't be moved, clutch in or out while in anything but neutral.

    I'm thinking a clutch rebuild. ??

    Engine runs fine. No previous
    clutch slip or over engagement issues. Just can't put it in gear.

    Right!

    But no, it's been riden a few times since the oil change / dipstick issue.

    The oil I use on my F800's is Motul 5100 4T 15w-50.

    Clutch lever end play? Not likely a worn clutch at that low mileage. Does sound like 'stiction' between plates, you should be able to move the bike around in gear with the clutch pulled.....not easily, mind you, but you should be able to move it without turning the engine over. If you have the center stand try warming the engine and see if it will shift fairly cleanly into 2nd gear with the clutch pulled. Mine doesn't turn the rear wheel when in gear with the clutch pulled but the wife's does a little. The goal is to exercise the system and shift the plates. That 15W is moderately heavy oil base, nothing wrong with that but it will grab the adjacent plates and present these symptoms when oil is cool or cold.

    Great info, thank you.

    I'll warm it up later today and try again. I don't have a center stand on this bike.

    I did try shifting it into 2nd yesterday, with the same results. Lurch and stall. Damn near got away from me as it went about 18"before stall. Tried 2nd again with front brake held. Same results without the movement, rear wheel scratched. ( This can't be good for the trans and engine).

    Clutch lever play is in spec. Clutch seems a bit loud when the lever is pulled compared to my F800 GSA. Clutch is silent when engaged in neutral, ( lever not being pulled).

    I followed the clutch cable down to the case, it's function is normal. It moves the actuator rod as per normal.

    I'll try breaking the plates loose tomorrow with a long warm up as you mentioned. I'll wait until the fan kicks in.

    This is funky. Pretty weird sh*t. I'll tear down the clutch more than likely. I'm guessing a broken spring jammed it up. ?

    There was no metal bits or shavings, and no clutch material in the oil change last month. Oil came out looking brand new. Filter same.

    Thanks again.

    You know with the jacked up dipstick, and now this clutch BS, maybe someone did actually [email protected] with it when we had it out a few months ago for a ride.

    Gosh - - hope not.

    How did you correct the dipstick issue? Re-reading your post about that event, it sounds more like the tip of the dipstick was bumping into something, not allowing the threaded portion to continue turning down and in. If you kept turning the dipstick when the tip was contacting a “wall”, that would result in cross-threading.

    After warming it fully and trying the earlier suggestions, I think I would proceed with an oil change and inspect the fluid/filter very carefully.

    I'd tend to agree, this seems more than a simple adjustment or warming the oil will resolve.

    [QUOTE="Vark, post: 42613860,

    How did you correct the dipstick issue?/QUOTE]

    I purchased aluminum oil caps from ProBolt. I now carry the original dip stick in my on bike tool bag for oil level checking.

    The threads on the original dip stick were stretched.
