    Anybody else have problem with clutch plates sticking when bike is cold. If I don’t break them loose by rocking the bike back and forth with bike in gear, I get a significant crunch when first putting it in gear. I remember this from the old triumph Bonny days but thought over the yrs tech in clutch plate materials would have improved?

    Are you using a different gear oil ?

    Not on the Norton, but they used to stick solid on my Daytona 1200 and rocking the bike wouldn't shift them, so I tied the clutch lever back to the handlebar when I wasn't using it and that worked for me.

    Yes , This I agree with. Change the oil you are using in the transmission . Didn't you recently service the primary drive area ? So the plates are clean ? What weight oil ? I know 5W40 JASO MA full syn works .

    I’ll give a primary oil change a try. Everything else is going well with the Norton

    The primary oil is shared with the gear oil. It would be very easy to put some kind of gear oil in the gearbox that it not suitable for wet clutches!

    Folk on here have recommended Bel Ray gear oil designed for HD Sportsters (similar box and also shares its gear oil with its primary and clutch).

    I had the clutch basket nut back off a few turns which led to a crunch to first and having to double clutch into third. Also, there was only about 4oz. of fluid in the tranny after only 500 miles of my dealership assuring me all oils had been changed. Lesson learned. Check tranny fluid often.
