    Intermittent gear change issue

    Hi all

    Just got myself a TTSE 2016 and it seems to have a gear change issue, when cold you can change through all 6 gears. When it warms up 1 N and 2nd are always ok but it wonít go from 2nd to 3rd or sometimes 3rd to 4th or 4th to 5th. It doesnít even try the gear change is like you have put it in 6th but still being in 2nd. It is only a problem going up through the gears.

    I found that when it happens if you move your foot from under the gear changer and move to the left of the gear change, so your foot is just catching it will change every time.
    I assume this is putting pressure on the gear change leaver in a different way.
    The other thing I noticed is sometime the gear change sounds really clunky but other times itís really smooth.
    Is there any known issues like this? I read that the was a recall for this leavers position?

    Thanks
    Colin

    The first thing to check is: Remove the aluminum plate where the left footrest is anchored, once the aluminum plate is removed, check if the screw that holds the gear change pedal is broken, if so, there are several posts in this same forum that talks about various ways to fix the screw problem.

    In the following link I talk about a modification that was a complete success for me:
    https://www.triumph-trophy.com/index.php/topic,12454.0.html

    If the above mentioned, everything is correct... The second thing to check will be the adjustment distance of the gear change pedal:
    Only motorcyclists know why dogs stick their head out the car window.

    Hi Big-Col from a fellow "Brummie" !

    As digital has mentioned, it is possible that the Gear Pedal pivot bolt is broken or loose,
    or even in need of some lubrication,  It is known to be a weak design !

    There should be no difference in where your foot engages with the pedal.
    and the pivot bolt is a known weak design.

    the Side Control Plate that has to be removed to access it ks secured with the same bolts
    used to secure the front brake discs ( ! ) and need a Torx driver ( T20 if I remember correctly )
    to remove them. 

    They are TIGHT due to being coated with a thread locking compound, and care must be taken
    using a good quality tool to ensure the bolt head splines do not get damaged while unscrewing them
    as this could make them very difficult to remove.

    If the Gear pedal bolt IS found to be broken or damaged, let me know and I should be able
    to assist in removing the broken stud part, and replacing it with a modified part.

    Cheers  :821:

    Thanks Digital & Coconut

    Checked everything and all seems ok I think it may be my foot is not letting the gear leaver return back fully after changing gear. The leaver needs to be moved up to give room for my big feet!!

    Triumph say the position / hight canít be adjusted is this correct?  I would have thought the linkage would remain the same and the spline could be rotated to move the leaver upwards?

    Hi again,

    The Gear Pedal position CAN be changed by moving it on the splined shaft.

    You need to make sure not to move it too far though, or its movement
    will be impeded as the pedal will hit one of the bolt heads of the engine cover.  :012:

    After moving the pedal on the spline check for unrestricted full up and down movement.  :169:

    If I remember correctly when I adjusted mine ( for the same reason ),
    it was the upwards movement that could get snagged.

    I'm only up the road from you in "B31" so if you need a hand with anything
    drop me a Private Message to arrange !  :028:

    Cheers  :821:

    I bought new boots a few weeks back which are far more substantial in the toe areas than my last pair.  As a result it was difficult to get my foot under the pedal for movement up through the gears.  I tackled the lever adjustment, and although fiddly, it was easy enough.  I was able to move the pedal position up about 25mm with no issues.
    While everything was apart I also replaced the pivot bolt with a brand new one just as a precaution, although the old one looked fine.
