I have a 2002 Suzuki Katana and being proactive and overly ambitious, over filled my oil (probably about a quart over) similarly to this guy:

I wasn't too far over the F mark in the oil window there was a visible bubble at the top, however as I've read this is often not overly accurate.


After changing the oil, the bike sounded very sluggish (requiring the choke to start and backfiring a bit), I thought this was just a symptom of being cold or not being ridden over the winter.


I did take the bike out for a spin for about 20-30 minutes and was eventually able to ease off the choke, as well, the back firing had subsided as well.


The real problems started a few days later when I wasn't able to get the bike to start at all. The bike cranks, however won't turn over. I drained oil out of the bike to the correct level. I checked the spark plugs and they had been fouled by oil. I also tried to clean out any residual oil in the cylinders.



To date I've:

-cleaned out the airbox
-cleaned the air filter
-cleaned the spark plugs
-blown out cyclinders with compressed air
-blown out vent lines
-corrected oil levels
-tried starting the bike with cold start
-pushed the bike around in 1st
-charged battery
-(pleaded with the bike to start)

The bike does occasionally backfire, and also will fire on what sounds to be one cylinder, however it is a far cry from turning over.

Any ideas on what to try next? Thanks GTA Motorcycle;



Probably doesn't help any, however here's the bike cranking:
