Dash problem solved

[senator8]

Hi Guys,

Thought I would share this in the hope it may help someone in the future. Earlier this week I received & fitted some Akra headers that my lovely wife bought for me as a birthday present from ridersdiscount.(thanks TJ)

All went well & I removed the servo motors after a few checks to see if any faults would come up on the dash. Upon starting and allowing the bike to warm up, I gave it a few revs and noticed my tacho would sometimes hang or become stuck. Further investigating would make the shift light randomly flash, the backlighting flicker and the tacho needle doing all sorts of weird things. Also taking the bike for a test ride the quick shifter would not work while the tacho needle was stuck.

I pulled the bike apart and replugged the servos to check if maybe the electrics were doing something silly when the valves were meant to open, as it would fairly consistantly play up around 4-6lk rpm. No change so removed and put the bike back together.

Decided to call my local dealer and ask if they had come across this before. To my happy surprise the service manager said yes! They had a bike doing the same and it was bad battery terminal connection!

I had checked the battery terminals and many other electrical connections, but decided I should clean and retighten the battery terminals and all fixed!

Excellent. Thanks a bunch for following back up on this and posting the resolution. So many don't. This will certainly help someone in the future!!

Good feedback for others, glad you`re sorted...the battery seems to play a huge part in the bikes well being.

Off topic, has anyone does this on here....standard exhaust without the cat, that sounds great...any info with pics on the set up..thx

Almost any odd electrical malfunction.....first thing to check is battery terminals. And if the battery is at all suspect, replace it.

Just an update to this.
A few hundred klms later my bike started doing the same thing. One thing I did not mention was that I have/had a Shorai battery.

I have now reinstalled the stock battery and no more problems.
So either I have a faulty Shorai or there is some sort of resistance problem with this battery that the S1000RR does not like.

I have emailed Shorai twice in the past 2 weeks and still no response.
Copy of my email below

I have LFX18 that I purchased for a BMW S1000RR. The bike will not run with the battery. The dash flickers and the tacho works erratically. I contacted my dealer about the problem and they said to check the battery connection (assuming it was a stock battery). I have removed and replaced the stock and Shorai several times and the problem is repeatable with the Shorai installed. Are you aware of this issue or do I have a defective unit? I purchased from #####. Thank you
