What's my ESA doing?!

[Slipperyeel]

Following some other posts on here recently I took the chance today to cycle through the pre-load options... just to see if it was behaving (I already had a sneaky suspicion it wasn't).

Having just cycled through all the options it's clear it needs some attention. Which should be expected as I'm leaving for Italy next weekend!

The pre-load is changing, it quite clearly moves up and down. The problem is, it's out of kilter. On low mountains it seems to remove all pre-load, then the next setting 'high mountains' it adds lots of pre-load. Then it seems ok on one helmet, helmet with luggage...

Anyway, does this sound like a 're-calibration' would get it into order? Is this something a GS911 can do - or do I have to go to a dealer?!

Thanks for any advice

ps. Damping is working

911 runs it through the full cycle. Recalibrates it.

Thanks for that (an answer I was kinda hoping to hear). Because it is actually adjusting the pre-load rather than nothing, my hope is that its pants are in a twist and it needs a 'reboot'.

I'm going to give Steptoe a call in the morning to see if he can help.

I just got mine recalibrated to see what happened, it wasn’t Not working but my friend got a 911 and wanted to play with it!!

Well, I have had the idea to buy a GS911 (and play edith it ) but right now I have other things to spend my money on... but I can see it's coming, at some point! I also haven't got time to learn how to use it - though for all I know that might be the easy bit!

It is as simple as the video, I done mine 2 days ago just to play with my new toy.

Hmmm... you're selling it to me... tho just at this moment in time I think with the trip ahead of me... Steptoe might be my answer (assuming he's not off sunning himself somewhere!)

One detail I'd like some more advice on. I always understood (I'm new to ESA) that the motor should be running when changing the pre-load settings? I just suspected this was due to battery drain and I noticed in the video, the bike is plugged into a charger... so am I right about the battery power?

When I run my esa through the hoops I do it with the engine running, and when doing calibration with GS-911 just engine turned on, and battery on tender.

I suspect the Preload motors draw a fairly hefty current hence the need for the engine to be running, but when doing a calibration with the GS911 the engine does not need to be running. When I had problems with my shocks/ESA I did several calibrations as I tinkered around without running the bike up or charging the battery and all was fine.

Back to the original problem though. Without buying a GS911 you could easily check how much the bike changes after each change in ESA setting. Simply measure the height of the back and front of the bike to the same spot in each of the 5 settings.

1 Helmet is your datum.

1Helmet + luggage should be raise the back a bit.

2 Helmets should raise it a bit more

Small Mountains should put the back to the 1 helmet + luggage position, AND raise the front a bit.

High mountains should raise the back to the 2 helmets position AND raise the front a bit more.

Return to 1 helmet and everything drops, the front usually with a sudden drop.

If its doing anything else a calibration might help, but it could be your ESA motors are knackered, although a fault (yellow triangle) would have shown at some point, but does disappear after a while. There will be a fault code stored though.

Good luck, I hope its just a calibration.

Austin. Your feedback and posts on the ESA story have been really helpful

You have though just given me a heads up in the pre-load positions... and I'm beginning to think it might be all ok .

Basically, I hadn't really clocked that the the 'small mountains' actually lowers the pre-load on the rear. I think I had an idea of what it should be doing, but based in your comments ref the height from a datum point, it sounds like mine is indeed behaving. Arghhh!

I'm going to look again tomorrow. But I'm also going to get a GS911 onto it. Just to put my mind at rest.
