More ignition coil troubles with 26K showing on a 2001. I have been experiencing a stumble or misfire coming off idle for several thousand miles. Lately the stumbling became so distracting I was no longer enjoying the ride. I searched the threads several times looking at what was said about low speed missing, stumbling, etc. Carbs and coil replacement seemed to be the common fault. I can grudgingly do maintenance on carburetors but was not looking forward to it. Based on info from the forum I gambled and replaced the coil. What luck!! My Bonnie runs like a top. Strong idle, no stumbling…no carb work! Several hundred miles later and things are still looking good. Thanks to all who contribute!

Additionally, I applied plenty of dielectric grease to all four connections on the coil. The low voltage connections are open to the elements. I have not experienced a gulley washer yet, but I did ride in light rain near McComb/Natchez Mississippi this weekend without any of the normal "wet" symptoms . So far so good with that also.

Thanks again

Yeah Mike I lost my coil at 700 miles on my bonnie black, I have since traded the bonnie in on a scrambler and plan on getting a noligy aftermarket coil and replacing the stock. The coil problem seems pretty common but can't say that I have heard anything about carb replacements though.

If you EVER touch your carbs, buy the carb bolt kit from New Bonneville BEFORE you do it. The screws are the cheapest stuff I've ever seen on a bike and strip easily.

Mike,

Did you use an OEM coil or an aftermarket coil?

Aftermarket..... Nology.

Opinions only but GILL may have some issues to work and they may have already, but I have replaced the ignitor and now the coil on my 01 bike. OEM ignitor.

I'm on my 2nd ingnitor (actually, my 3rd because Triumph gave me a 790cc replacement igniter when my OEM went bad).

Plus I added Nology Coils.

They are OK if you use the correct driver.

How do you guys know when the coil fails ??

I have been having similar symptoms to those you describe but have been blaming and messing about with the carbs...

Is there a test you can perform to check the coils ??

 

[Dirtbikemike]

No scientific diagnosis!... Maybe some of the more skilled folks out there that can say?

I read the threads.... drove the thing until I could no longer tolerate the stumbling and sputtering.. Then I dropped $80 on the replacement coil. Meanwhile, a good friend who has been in the bike/ATV business for years was confident I would find water in the float bowls or a plugged pilot jet. Since I had already bought the coil when I got the carb advice I tried it first and lucked out.

It makes all the difference in the world when it runs good....

Again, maybe someone will tell us how to check the coil but I don't know. Good luck!

Mike
