Default Re: what did you do to your motor bike today?

Then I realized that even though that there is good spark, when the engine is running and vibrating, it is causing a fault in the line to stop the spark!!!
So out comes the magneto again, this time I set a .0030 gap and then striped the lead down a ways, and attached a coil wire from a car to my magneto lead and it FIRED RIGHT UP AND RAN SUPER!!!! I could not belive it!!!! what a problem that was solved. Right now I still have to put all my stuff is Christmas morning. So Happy Holidays everyone!!! You dont have to get drunk.
Anyway, this morning I learned that even when there is good spark, THAT DOES NOT MEAN ANYTHING WHEN THE MOTOR IS RUNNING, BECAUSE OF THE VIBRATION. The tinyest fault in the lead will cause a spark faliure as it is rapidly vibrating with a running motor......Later on today when I get up, I'm gonna throw my old carb back on and save this new one...HAPPY HOLIDAYS EVRYONE!!!!
Excellent troubleshooting, Blakenstein and thanks for sharing. Yep, the less alcohol I buy, the more I can spend on my bike!

I'm a cheap drunk, anyway. I'm flying before I finish my first beer.

I mounted my $14 tach onto my windshield post, with $2 worth of a bracket, nuts and bolts.
