Hi Everyone!!

I've had a consistent problem with my gear indicator display mounted on the instrument cluster. In neutral, the neutral light illuminates, but my display shows 2. when in top gear, I get a backwards 6. everything else in between is a mash of weird squiggles. I've already had my cluster apart and cleaned what I could reach, is there another, easy to reach place for me to clean? Indications don't bother me, just curious if its an easy fix.
Cheers B

First is the connector behind the right hand battery cover, than it would be the switch itself. This has been known to fail on occassion due to dirt and moisture. Bitch of a job to get at, so keeping our fingers crossed that some cleaning behind your right hand battery cover fixes it.

Has anyone replaced the gear indicator LCD? Mine has bled out, it is completely black. Happened gradually over the past year. Bled from top to bottom. Oh, 85 K100RS.

Thanks,

Hi,
As noted above the switch is difficult to get at but is prone to getting water in with the result that it gives weird problems. Bad connections in the speedo head can also give troubles and those are common on early bikes like yours as the instrument clusters let in water and the humidity attacks the connections. So refurb of the cluster is a good idea and thorough sealing up. Even though I have the Goretex vents mine used to fog up after rain until I got in there and did a thorough sealing job. No more misting since. Replacing the display is fairly straightforward just fiddly.

Where might I find a replacement gear indicator LCD?

Thanks,

hmm my lcd displays are buggered as well and my neutral light only sorta works when it wants, but some times u can tap it and it turns on... only when its in neautral tho.

I too should like to clean the Gear Position Switch to hopefully stop my really annoying teenage-like display constantly getting things wrong !

I do however have a very small technical problem completing this task in that I simply cannot find it! The Clymer hasnt helped this time.

Can anybody please recommend an achievable and perhaps not too-contorted body position that i might adopt to locate the switch please?

thanks again

Easy!

Remove the swing arm and you will find it..
In fact its an easy job but the whole back of the bike has to be removed (wheel, back brake,differential, shaft)
The gear position switch is located on the back of the gear box.
This is another week end of fun, but the best time to do it is when you grease your splines.

thanks Bert
Off to put head in gas oven !

OK..well Bert, I just sent you a PM, but I think I already know the answer.....

Thanks,
Rick

Hi there, mine tends to fail wen driving on cold weather (only once a year) or wen riding very wet roads, and returns to normal once the bike gets dry, so dry it with a hair dryer and save time.
Best regards

Greetings all Replacing the gear indicator switch really isn't that tricky at all. I have digital images of me performing the task. If anyone would like a copy, don't hesitate to contact me and I'll send them down the line.

NO NO Johnny, this is realy not that bad a job just follow Berts method and remove the stated items, I followed the how to section in the downloads and stripped and cleaned then re-sealed my switch [that was not working at all] and hay presto all back to normal, if yoy use this time to have a general look around as well including clutch arm then it will give you peace of mind.

BIG D

You can use this :arrow: http://cgi.ebay.fr/INDICATEUR-DE-RAPPORT-ENGAGE-GEARTRONIC-PZ-RACING-/380334431393?pt=FR_JG_Moto_Pi%C3%A8ces&hash=item588db2dca1#ht_958wt_1330

Hi All,
The problem Alex lists is almost certainly a bad connection in the instrument cluster or the plug and socket on the back if percussive maintenance aka tapping causes it to work again for a while. Opening it up as I detailed in another post and treating all connections with DeoxIT will fix that and at the same time consider replacing the bulbs with LED's except for the charge light.

Replacing the gear indicator LCD is simple. All you need is dismantling the instrument cluster.

I did it on my bike. I got used instrument cluster from eBay. I used the speedo unit and the gear indicator LCD. I use this as spare for other parts of instrument.

But you may do checking and cleaning the connection before replacing the LCD.

Good luck

Thanks guys, good info.

I Got good advice from Inge K on my post "My Nautral light has stopped working"


This helped me find the problem.....

You could try this before taking the swing arm out.

good suggestion paul

Wow - Thanks Paul - this is what I call a forum.........

I have the skills to do the Mod and I understand the concept....

I also have the tools to take off the swing arm and do the repair/replace the switch ..... to do both and never think about it again....... !!!!!

Hi Mark,
I did that mod well over twenty years ago and the only problem I've had was a broken resistor lead, which, when repaired restored the indicator function.

However, 3 or 4 weeks ago, I got caught in a cloud burst, with roads flooded and down to 20 mph. Then the indicator started giving random readings. No problem, I thought, just check the resistors and 'DeoxiT' the connectors.......but all to no avail.
After a couple of rides, I figured that the switch had finally given up, so I bought a new switch from Motobins at a mere £80 .

Of course, as dictated by Sod's Law, on the next trip the gear indicator finally dried out and started reading correctly again......and has been ever since!

Ah well, it's always useful to have a new spare.

Good luck, I hope it works for you,
Paul.
