When I restarted it, I was greeted by a "required service" message and the light was very dim. I took it to a Honda dealer and they did the following: -
Removed the factory battery (They said they needed a new battery to test it, but then replaced it with a new one)
Started the bike by pressing the key, and had a look at the DTC warning lights and the oil pressure
Pressed the key, it tried to start and nothing happened, no lights or sounds
Pressed the key, it tried to start, and a gentle hissing sound came from the airbox area, but nothing happened
Refilled the oil in the bottom of the engine and oil lines (I tried to reduce the oil level, but it wouldn't start no matter what I did, including leaving it for a couple of days)
Pulled the plug, set the ignition switch to position 2 (as there was no battery), and started it
It ran fine, no noises from the engine, no smoke, but the lights were very dim and the oil pressure was very low
When I got home, I set the fuel mixture to minimum (which I've never done before) and did a pull, nothing happened
I set it to full throttle and nothing happened
I tried the throttle the other way and it ran good
I tried the gear position selector the other way and it ran good
I tried the ignition key the other way and it ran good
I didn't do any further test as the dealer said that no other test would work, but I was happy to know that it was running fine. They said it needed a new battery to test it and the computer so they resoldered it.
They said it was an 8 p.s.i. pressure and they installed a new part in the airbox, but I don't know if they actually did. They didn't mention anything about it being very slow or very fast. They said it was a slow engine, but I think that it is very high.
That's it, I've now had a very, very expensive lesson, and it was because the engine was under oil pressure. After getting it running fine, I thought I'd reduce the oil level and check the oil pressure and oil temperature, but the factory oil capacity is too low.
My question is how can I reduce the oil capacity? And the oil level would 0b46394aab
