I don't think it was the breather hose since this is the first time I had the tank off. She has 11K miles without trouble until just recently, which got me off my lazy butt to do something. (if it ain't broke...)
The rubber tubes hooking the carbs to the airbox look OK. I haven't pulled them yet so all is still factory tight. (Factory set DOES say something, doesn't it? Hmmm...)
The airbox has a good crack in it from a backfire when starting. (That will get you noticed in a crowd!) The air filter hasn't been changed but it looks good, only crud on the lower part of it. (I stopped buying stuff when I gave Santa my list, and the filter was on there.)
I don't have the tools to check the coils for amount of spark, but both pipes get evenly hot. I was checking for one side to be missing while it was still on the jack and tied down securely. Don't do that if the straps are on the forks so they are out of the way -- I now have shorter straps and gunk to clean off the pipes. BTW, they melted through within seconds of each other, so both cylinders are firing about the same.
I had lots of backfiring in the silencers before this AI removal. Now it is down to almost nothing. And to think I waited all these miles to do something about it. You guys have been telling me but I was just too lazy and wanted to play with the bike instead of work on it.
I'm going to pull the tank and dump everything out of it today. Hopefully it will be the simple thing this time. I hadn't thought of water and the mixing of the it into the gas until I was typing the initial post.
Guess I'll clean up some of the dielectric grease while I'm there. (If a little does a little good, then a lot...aw, forget it.)
