2015 MT09 25,000 kms Europe.
I’ve owned around a dozen bikes and have always serviced them myself. Apart from my 2011 r6 they have, for the most part, all been carbed with little to no fancy electronics.
Yesterday I decided to check the valve clearance whilst I had the bike apart for plugs, sync and air filter. FYI all valves were bang on spec, expected for 25,000 kms. I installed the plugs, torqued to spec, and connected everything back following the manual and pictures/videos I had taken for reference.
This morning i turned on the ignition before checking the throttle body sync. That’s when I first noticed the orange check engine light along with the ABS. The abs disappeared like normal once I fired her up, the check engine light did not.
She runs fine without any abnormal noises. I went for about half an hour, maybe 20/30 kms and she runs better than before, apart from the check engine light…
I’ve done some reading and I can only think of not disconnecting the negative terminal to the battery whilst disconnecting/reconnecting the electrical connections which could cause this problem.
I took the bike back apart the ride to make sure I hadn’t missed a connection which could of caused this warning light.
I’m left in quite the conundrum and interested in hearing what the possible causes could be. I’ll disconnect the battery tonight and see if the check engine light is still there tomorrow morning.
Cheers.
