Bike hasn't been running since last sept. BUT
After advice from you guys!!!; cleaning up some ground connections, and other electrical componenents. I FINALLY have spark!!
BUT BUT BUT she still won't run. I have a blue spark when I groung the plugs to the frame, when I did this before I had no spark --- how aggressive or "fat" should this spark be? (My spark kinda looks slightly larger than the spark you get from those "button" type electric bbq ignitors.)
I tried new coils and a new CDI and the spark is the same "size". So I was wondering if ignition timing could be a possibility, or maybe a bad pickup coil in the ignition rotor housing....? Maye the problem isn't electrical at all.......
The gasoline in the tank is at least 7 months old. But I added fuel stabilizer sometime around christmas....when the fuel was 4 months old.
Could the problem simply be old gasoline? The fuel is flowing from the tank into the carbs. so no clogs. ----- Next chance I get to work on the beast I will replace the old fuel with new. -----
I have tried everything I can think of, now I need some help on some possible problems. Any advice to get an engine running where everything seems to be working properly?
Should I try an ether spray or something like that into the carbs, to get this thing to fire!!!??
ANYTHING would be a help and greatly appreciated!!!
Thanks everyone!!!!
Here's my old post regarding the same issue, which might help give some insight on solving the problem:

Last summer when pulling away from stops, my bike underperformed until it reached the higher revs. --- I was told this is due to a battery-dependant ignition system. Meaning, unless the bike has a good quality battery to provide proper spark during the low revs it will not perform well until it reaches the higher revs, when the alternator (generator) starts creating enough energy, recharging the battery, to provide proper spark. ----
The scenario: One day while riding normally, my bike suddenly lost power. It didn't stall, but it felt as if only firing on 3 cyls. for example. Then after a matter of seconds the problem corrected itself and I rode the short trip home. After parking the bike for the night, I went out the next day, only to sadly discover that my baby had no heartbeat. It just wouldn't start.....no spark
I was surprised at this since this was just a day or two after I got back from a motorcycle trip with a buddy where we drove a couple thousand km, and the bike never acted up once.
...so, I killed the battery running the starter. Then I charged the battery. And tested the electrical system. Everything was within the specified ranges. Then after finding out about the battery-dependant ignition deal, I figure it's a bad battery. BUT, after installing a new battery I still had no spark.
I tested for spark by grounding a plug against the frame. I tested both coils and all four plugs and wires, but NEITHER coil had any spark (each coil tested within range of specified resistances, so figure they're still good). As well, it seems highly unlikely that both ignition coils should fail at the exact same time. but neither is creating spark.
It's definatley electrical. The plugs are new, and the bike was running perfectly prior to this. Other than the chronic hesitate-from-a-standing-start problem.

Okay, so now that the electrical problem *seems* to be repaird (I have spark -- do I have enough?) what else could the problem be?
Thanks again everyone!!
