Help!!

More precisely;

1; Does the bike start normally and what is the initial idle speed?

2; are all four exhaust pipes warming up?

3; does it sound like some cylinders are missing and if so how many and which ones?

The bike has two ignition coils, one for cyl 2 and 3 and one for cyl 1 and 4,
One cylinder out is a faulty spark plug, a pair of cylinders out is loss of a coil system.
And a healthy spark is 21mm long with the engine running, i measured it.

4; does the fuel pump sound different ( higher pitch ) than normal?

5; it's 7 days later, is the bike back to normal?

The logic behind these sentences is simple enough, ... once you understand it, and you are able to apply it. So let me rewrite it a little - not so much for kencal who may have given up - but for any initial trouble shooting, while out on the road:

With engine running rough, not starting well, etc. ... and related problems:
- measure the headers temperature (with your hands if cold enough)
- all 4 coming up and all the same: good
- one remains cold or cooler: check spark plug, and if you can the sparks produced
- two remaining cold or cooler: check coils (if you can), and wiring
- all 4 cyl.: listen to the fuel pump

One could easily turn these ideas and many similar ones into a very useful flow chart, which I still have to see here on the board or in the manual. I am sure the Honda dealers have it.

Anyway I will make sure to remember Max' words !!!
