Stop missing shifts. Fix your sloppy shift linkage.

- After 27k hard miles on my KTM 390 Adventure I noticed the shift linkage was loose and wobbly causing me to miss a lot of shifts. I also became concerned I could strip out the shift shaft or the shift lever making impossible to shift. This problem had to be fixed. The best way to do it was to replace the shift linkage making everything feel brand new. So no matter which bike you might be riding it is worth keeping your shift linkage tight.

Thanks for this. I have a KTM RC 390 and the same sloppy shifting. I replaced the tension rod (the adjustable bit) but still missing shifts. I will defo replace this lever before stripping out the whole mechanism. I like spending time in the garage but let’s try the easy stuff first 😅
Also, loving how cheap the parts are for these bikes. Waaay cheaper than equivalent Honda, Kawasaki etc bits and pieces here in the UK.
Thanks again, have a great day
Glad this was helpful. It made a huge difference for my bike.
your tutorials just get better and better man, as i always say thank you for all your content! valuable forever
Thanks, really appreciate the feedback. Cheers.
I think that neutral is a myth on my ktm. Thanks for sharing this.
After doing this I can find neutral with no problem.
I had the same problem with my 390 Adv. But I seen on UA-cam where if you rev your engine slightly it makes finding neutral easier. I now find neutral a lot easier.
@@jons1148 yep that works. Solid linkage has made it super simple to find neutral.
I,ve tried every adjustment on mine. I give up. I shouldn't have to blip the throttle to find neutral or any other routine. Infuriates me that I have to reach down with my hand to move it precisely into neutral. Only thing that I really dislike about the bike. Never had this problem with any other bike I have owned or even operated.
@@jacknimble1 once I replaced up the linkage it has become really easy to find neutral. Maybe try replacing your linkage and see if it helps. It made a remarkable difference for me.
Damn, now I need to go and check - Frank
I find neutral every time now.
At 15K miles mine is sloppy. Going to order up the parts. Thanks!!
It feel so much better after changing the linkage.
Got it. click the link for shift shaft linkage for shitty shifting. whew.
I do have the same, I periodically tighten up the change arm millings(10mm bolt).
Be careful not to break the bolt over tightening it. Replacing the linkage is a better solution long term.
@@advmatt Totally agreed. Also I prefer blue loctite on those threads. Keeps them in place for a longer period.
Well explained. However, the upper link is also worn out and far from ok. I would have like to see that. Which part is word out?
The shift lever that slides onto the shift shaft was worn out and the linkage bushing was also worn out. The connection of the foot shift lever to linkage attaches via a pin and clip. Due to this interface there is no way to tighten it. Maybe a new pin could be installed but it really didn't look worn. This is not a tight fit even when new. There will always be a little movement here due to the way it connects.
@@advmatt I'm glad you looked into it. Thank you so much for your video channel.
I am afraid that will not help you for long, mate. No matter if new or not: the reversing lever just gradually slips off the shift shaft, and you can feel as soon as you push it in that something on the engine side is pushing against it. I just haven't fully figured out what it is yet. Likely it's the cone that sits too close behind the shift shaft teeth. In any case, I suspect a design or manufacturing failure. Even with the new bike I already had this issue after around 1,000 miles.
I will try to apply Loctite 222 (low strength) on the shaft and see how it goes.
You might be right. I will find out in a few months if there is a bigger problem. I hope not.
I have found the root cause of my case.
The diameter of the lever mount for the shift shaft is narrower on the engine side than on the visible side. When tightening, only the teeth behind the undercut engage, which causes the lever to wobble around like a loose tooth when shifting - can be seen very well at 0:26. What we also can see is that it can more easily slip off the shaft. Cause...maybe wear and tear from the gear shifting work.
One could now try to bend the clamp together in the vice at the front. Or you can indeed get a new lever (and measure its diameters with the caliper before installing it, to be on the safe side).
What I've currently done is "lubricated" the shaft well with Loctite 222 and flooded the front of the whole thing with it after assembly as well. Let's see, maybe it'll help.
