Brand New Bike - Clock Losing Time
« on: April 03, 2020, 02:08:34 PM »
Not really a problem but more of an annoyance.  I bought a new 1200 Tiger in December and at present covered less than 1000 miles.  Everytime I go to the bike I notice the clock has lost time, so much so I have been recording how much and its about an hour and a half every 2 weeks. 

I know its no real problem, just an annoyance  but is it the start of something ECU related?

I'm ashamed to say but I've not even been out on mine this year yet but went out to see.
It's showing the correct date of the 3rd April but 13:38 when it was 15:55. That'll be nearly 6 months since it was out  :027:

Hmmmm, I think there's a drain issue on the bike. Clock might just be the side-symptom. Something is draining voltage somewhere... I'm sure more knowledgeable people here can help you pinpoint it with a voltmeter and probing here and there. I'd just take it to the dealer and tell them what's happening and ask them to fix it asap.

The clock is internal to the TFT so if it's not being caused by a very low battery fault then there's likely something amiss with the TFT.

The clock signal should be derived from crystal source on the TFT's circuit board, usually running at 32.768kHz. Normally a quartz crystal is VERY accurate but if you've got one that's losing around 1hr per month then I'd mention it to the dealer and get your TFT replaced (if it bothers you).

When the ignition is turned off, the processor controlling the functions inside the TFT will go into sleep mode (after a time). While in sleep mode it should have a bare minimal drain on the battery while it keeps the internal clock running and keeps other parameters saved in RAM. If you disconnect the battery the clock and RAM contents are lost, which is normal practice. The 12V battery voltage is regulated inside the TFT to 5V, 3.3V etc to power the electronics so I'd be more inclined to think that a low battery would eventually cause the TFT processor to shutdown once the regulator dropout voltage has been reached.

Thanks Guys,

 I am about 200 miles from a dealer & as the bike is only 3 months old and its not getting used just now(obvious reasons)  I will keep an eye on it.

Perhaps it is because of the temporal shift that results from riding at speeds in excess of the ton?  Moto GP riders tend to lose on average an hour and quarter during a race.  :001:

Nope, sitting on an Optimate 5 and fired up on first turn  :084:

I'd email the dealer to give them advance warning of a possible warranty claim once lockdown is over & you can get the bike to them.
