APB 235 19 Posted January 8, 2023 Share Posted January 8, 2023 Hi, Wonder if anyone has any ideas. My NC750x 2017 was sat for two weeks over Christmas period but started fine last week for two day commuting (120 miles or so) with no problems. Today adjusted my chain and put bike in gear on while on centre stand and revved bike to check chain and wheel all ok. PGM-FI light stayed on and solid. Rode bike down drive and abs light etc went off but warning light stayed on. Looking on other parts of forum, I took bike for a 40 min ride and bike rode perfectly with no issues starting, idle, revving or speed. Light stayed solid throughout. Read somewhere that I could have caused fault running bike on centre stand in gear. Is this possible? Just want to narrow down options before call garage tomorrow. Thanks Andy Link to post

Don’t run the bike in gear on its mainstand. It confuses the ABS because it expects rotational speed of front and rear wheels to be the same, not one static. Link to post
Skidt 1,331 Posted January 8, 2023 Share Posted January 8, 2023 I did the same a while back, whilst cleaning / lubing the chain. I ended up ordering a cheap diagnostic tool from that auction site. I was going to use this to investigate and hopefully reset the light. this is the one that I bought. https://www.that auction site.co.uk/itm/283651302848?hash=item420aef65c0:g:HgoAAOSwE91dh6Jl However, a day or so later, the light reset itself. I’d give it a day or two and see if yours does the same. Failing that, I guess you could always disconnect the battery and leave it a while before reconnecting it. That might reset it for you? good luck. 👍 Link to post
jeremyr62 2,598 Posted January 8, 2023 Share Posted January 8, 2023 Not the same scenario causing it to come on, but when I was messing with the vehicle speed sensor I had the light come on too, and it also went out of its own accord after a few rides. So maybe wait a while before splurging out. Link to post

I have done this with every bike I have ever owned (wash bike, then run it to dry chain before lubing) without any issues and the last 4 all had ABS. When a bike is on a dyno surely it would cause problems if this was true? Have I just been lucky? 1 Link to post

APB 235 19 Posted January 8, 2023 Author Share Posted January 8, 2023 Thanks for the feedback. Will run it a few times this week and see if resets. If not, it gives me something to speak to the garage about. 1 Link to post
Andy m 23,729 Posted January 9, 2023 Share Posted January 9, 2023 The ABS has to log a fault when the rear sensor reads high and the front zero. After that It's a tick box in the design software as to what the light does (or a line of code given how ancient these bike systems are). Go out when the signal returns? Go out after an ignition cycle when there are two good signals? Latch on until the owner pays the dealer £137 to click clear faults? Which they tick will be an argument between legal, aftermarket and OE marketing at some design meeting. You can bet on Triumph and BMW choosing diagnostic tool reset and the more sporty brands that might meet dynamometers choosing automatic. Andy Link to post
Empty_Ten 455 Posted January 9, 2023 Share Posted January 9, 2023 Definitely sounds like it was caused by the bike running whilst on a stand. It's a recurring question on the MT10 forum I'm on. It's happened to me once before on the MT10. I had started the bike after a wash/clean/ACF50 but not running it whilst in gear. The bike was in neutral and not being run but the rear wheel was slowly spinning - but that was enough for the light to come on. Luckily mine reset itself when I turned the bike off/on again but it seems that those who were actually running the bike on a stand had to get the fault code reset. Link to post

RE Dyno's, yep it does happen on there as well but the tuner will (or should) have the OBD (or equivalent tool) to reset the light and remove the fault code. That's what happened when I had my MT10 ECU remapped. Link to post

Had it happen to a 2018 MT10 that I used to own in exactly the manner you described. Had to get mine reset though unfortunately. 1 Link to post
scc 66 Posted January 9, 2023 Share Posted January 9, 2023 I have adjusted the chain on mine twice. The first time I lubricated it and popped it into Drive on it's its stand and let the wheel spin a little. On my next ride out, the amber warning light came on and stayed on all the way home. It had though, reset itself by the next day. The second time I just tensioned the chain and moved the wheel manually for a visual inspection. Once again I got the warning light that reset itself. I checked with an obr, that came up with a low voltage warning. On a slight aside, I am chuffed that I have only had to adjust the chain twice in 8000 miles. Perhaps I ride like a big wet lettuce! 1 Link to post

It's not you that's a big wet lettuce, but the bike, other than some of the OEM versions chain life is another positive about the NC. 1 Link to post
APB 235 19 Posted January 10, 2023 Author Share Posted January 10, 2023 Thanks everyone, feel happier having seen all your responses. Will give another couple of rides and hopefully light will reset. If not, at least my local garage are really good biker guys. 1 Link to post
APB 235 19 Posted January 11, 2023 Author Share Posted January 11, 2023 Rode bike to work, stopped for fuel and light reset. Will be manually turning the wheel in the future. Thanks again for the support. 6 Link to post

Blandy199 31 Posted January 12, 2023 Share Posted January 12, 2023 I run mine on the centrestand at least twice a week to lube the chain, yes the light comes on, but it goes off before I get off the driveway and doesn't seem to cause any problems. Link to post

Andy Have me a squiggly moment as a mate of mine lost the tip of his pinky (finger ) year before last doing exactly this. One of those 'been doing it this way for years without a problem ..... Oops, ouch, blimey that stings' moments. Never really understood the 'advantage' of spinning the wheel by engine power as surely slower is easier to apply the splurge? 1 Link to post
Andy m 23,729 Posted January 12, 2023 Share Posted January 12, 2023 I'm not risking not being able to do my favourite hand gestures just to get a bit of lube on quicker. Andy 3 Link to post
Xactly 5,495 Posted January 12, 2023 Share Posted January 12, 2023 If you ever do it on a BMW oilhead, you wouldn’t do it again….. Link to post
Blandy199 31 Posted January 16, 2023 Share Posted January 16, 2023 Just to clarify, I use a Lubeman to drip the oil onto the chain rather than an oil can so as not to coat everything in a 6' radius with oil. When I had the Lubeman fitted to the bike, it kept getting all scrunged up with a mixture of road dirt and oil and stopped working after a while. Using it this way it is easier to get the required amount of oil where it is supposed to be, ie on the chain, not all over the wheel/tyre/me. Link to post
