    Steering lock issue...

    Hi

    My SR is a 1978 UK 2J4.

    It has the steering lock in the ignition switch, rather than down on the frame tube.

    It was working, but now I can't get it to lock.

    Any suggestions as to how I can free it up please?!

    I can't remember when I last tried it, but I did have the whole of the front end off when I first bought the bike, to do the headraces, fork seals etc.
    I'm just wondering whether I might have put something back on wrong, or whether something could be in the way and stopping the lock pin thing from coming out. But the front end was off during the winter of 2014/15 and I've ridden it 100's of miles since then, and am sure I've used the steering lock at some point.. but can't be 100% sure.

    I do think it's more likely that it's just stuck somehow though.
    I have no idea how the switch/mechanism works, so any advice/help would be very much appreciated please! :-)

    P.S. I have an original Owner's Manual, and have followed the description of how to do it, but I'm either not understanding the instructions properly, or the steering lock bit is stuck.

    The ignition switch works perfectly in every other way!

    We're getting a LOT of bike thefts here in the UK these days, so it's worrying me that I can't lock the steering.
    Need to get this sorted pronto!

    When you turn the key to the left or counter clockwise it allows the lock plunger to be released and when lined up with the indentation on the steering stem it will mesh and the lock will be "ON"
    Are you saying that the key will not turn to the left or are you saying that when it is turned to the left and you move the bars across its arc at no time does the mechanism mesh.?

    The key won't turn to the left.
    In the Owners Manual it says "Turn handlebars fully to right or left (I've tried on both sides). Give one push to the key at the OFF position, then turn it counterclockwise to the LOCK position & remove the key. To release the lock, only turn the key clockwise."

    There's also an illustration which it shows (a) a finger pressing on the key, (b) finger releasing key, allowing key to come back up, (c) key turning.

    I've owned bikes before that lock in this exact way, but not for decades. Feel like I'm either not quite doing it right, or something has stuck!

    The rod is definitely not out in the locked position because I have full use of the steering.

    There seems to be a few variations to the key switch/locks. Some you do not need to do anything but turn it to the left, some you must push the key down and release then turn to the left and some you push down on the key, hold it down, and then turn it to the left.
    You can simply look up under/behind the headlight assy and visually see the push pin in the lock and where it needs to go.
    Unless there is something impeding the exit of the pin in the lock or the full left or right of the steering stem it has to work.Up and down height does not really come into play.
    Try some WD40 or whatever you have in the lock and also on the pin ,where it exits the lock ...it may just have a bit of corrosion ..

    Ok, thanks!
    This makes sense because the Owner's Manual is one I bought on Ebay, and not the original one for the bike. It is for the correct year, but maybe the bike has a slightly different lock/key turn system. I will try all the different methods you;ve suggested! The fact that I'm sure I've had it working in the past, makes me think that I happened to catch it just right then, and now I'm following the book too well, and my bike is probably different to the book! I hope that's all it is!

    I've already squirted WD40 down the lock, but I haven't yet looked at the underside/pin area, so I'll also investigate that if I still can't get it to work after trying the above!

    Cheers! :-)

    You know, after reading this, I went out and tested my 78, and I can't get the lock to work either. I can push the key down, but either letting go or holding it down, I can't get it to turn counter-clockwise. I can see that the locking pin is not frozen up, because as I watch it when I turn the key, from off to on, I can see the pin retract a little further. But I can't get it to go out to lock. In this American backwater, I have relied on ignorant thieves, figuring that most of them can't start a bike if they can't see a big button labeled "START" (and a hot start on these bikes, in particular, isn't always easy.) Often, I must admit, I have left the key in the ignition when I walk into a restaurant or cafe. Knock on wood that it continues! PS The bike sleeps safely indoors when not being ridden.

    Any chance you two are using replacement or non OEM keys?

    For my part, I thought of that and pulled out the original Yamaha keys that I keep squirreled away... no difference.

    It's usually just a build up of crud that stops it going in. Need to be carefull as It can get stuck in the in position then your screwed. WD or similar and much wiggling. Oh and a main stand helps.
