Hi all.

All of a sudden my horn repeatedly sounds when I engage my tilt lock. Seems odd. Anyone had that happen. Shall I just disable the horn?

No, do NOT disable the horn. It is informing you that there is a serious issue.

Have you checked the fluid level of the tilt lock system?

Has the bike ever had any fluid leaks at the front end?

Do you regularly park the vehicle long term (more than a couple of hours) using only the tilt lock system?

And has the bike had a tilt lock service i.e. fluid flush and renewal?

Had the tilt lock done about 12 months ago. I have not sued the tilt lock for about 4 months and always use the stand as the connector got damaged. I have read that it not to hard to replace the fluid. Just a question what fluid do I use?

IF there are no leaks, then the problem lies elsewhere in the tilt lock system such as stuck motor, cable damaged/broken, pressure sensor, wiring issues, etc.

DOT4 is the spec for the tilt lock, same stuff as for the braking system

Or a small leak in the pressure switch.

If you EXACTLY have no pressure problems in the tilt lock system and you cannot quickly replace the pressure sensor, you can use the solution from the next topic and remove this relay:

One other thing to check...
I had a similar issue a when I first bought mine and the previous owner cut the price because they could not fix it either.

It was down a little fluid but not much. Filling it did not resolve it. Then I read(maybe here) - never use the tilt lock AND stand at same time.

I took it off the stand - still happened, then I thought like an engineer for a minute.


Take it off the stand
Start it
Turn off the tilt lock
Tip one side, then the other as far as you are comfortable holding it. Do left/right lean a couple of times
Turn it off and restart.

Now it only happens to me when I forget and use both.
