Hello everyone,
I'm trying to trouble shoot something on my 03 Katana 600. The bike is currently running on 3 cylinders. I tested using a temp gauge on the pipes and cylinder 1-3 get to roughly 750 degree, with cylinder 1 lagging slightly (at 690-700 degrees) but cylinder 4 was at <200 ish and steadily drops. I pulled the plug from cylinder 4 and checked the spark and didn't see it spark so I swapped cylinder 1 and 4s plugs and got the same condition (cylinder 4 still not firing).
I used a multimeter I had lying around but it only beeps for continuity, it doesn't read ohms/apms/etc. I tested the plug and it beeped and I pulled the coil for cylinders 1 and 4. It beeped when I touched both wire connections and when I put the prongs into each spark plug boot.... but not the boot to the wire connection.... Is that normal? Is there a way I can test the coils to see if they are bad?
A couple side notes... during my testing cylinder 1 hyrdolocked so I removed the plug and blew out the gas and it started back up (albeit the same condition of not firing on cylinder 4) AND I also tested by spraying starting fluid into cylinder 4's carb hole and the temp on the exhaust pipe raised roughly 20 degrees and dropped. Is that more of a fuel issue then?
Don't know if it's fuel or spark related... or a little of both but any insight would be much appreciated.
Thanks!
