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 like it was 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.
So where can the problem be?
Could it be as simple as a bad ground?
Could it be the alternator/generator?
Perhaps the problem lies somewhere around the signal generator rotor?!? can this part just "burn out" suddenly?
-All my fuses are good.
-All the lights work as normal....but the high beam indicator has always been iffy, sometimes it works, sometimes it doesn't....
-I bought a new cdi and wireharness from ebay that I'm going to mess around with, but I would really just like to end the frusteration and know what the problem is.
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.
If there are any questions or more details needed I can be very specific.
Any advice is welcome, and greatly appreciated.
Thank you so much!
