dialed in

When it's dialed correctly there should be no dead spots in the tach. Even at 2K in fifth gear, if you roll on the throttle it will come to life big time.

Well I put the stock pilot jet back in and now have some pickup between 2 and 3k I am happy with that, runs great, But nowduring the test ride it died due to no spark after an hour I got spark again any ideas?
the po installed a Accel super coil kit 140403 with NGK Iridium plugs. ignition fuse good whil I had no spark, after I got the seat off I got spark so I could not troubleshoot from there, Coil or TCI?
Thank you for your time and response.

Coil or TCI?
Thank you for your time and response.
Neither........ likely pick-up coil wire(s).

[imcgyver]

I hear about broken wires in the pickup coil assy, any common spot for the breaks or?
Thank you for your time and response.

The spark plug connectors can be suspect. I have seen them go bad only when hot.

I had something similar happen to me. bike died on my way out the driveway. When I got off the seat, I got spark.
I figured it was a loose connection near the fusebox, or the plug into the TCI.
Hasn't come back yet.

Hope this helps.

The longer sections of wire connected to the advance assembly........both hands pull on them bout every inch.........if insulation stretches, ther's a break.

I know your on to spark problems now, but I thought I would make a recommendation. Once you get your spark problem worked out, try bringing that main down to a 117.5. That with the 42.5 pilot should be about right.

no spark

Not that I want to go against the grain of this thread, but if he's got NO spark at all, then that would mean that both wires on the advance would have to go bad at the same time.
I do agree that this is a common failure on our bikes and had to fix one of mine, but if he's lost all spark, then I think the issue may be elsewhere.

Actually there are several documented cased of a single pickup coil failure causing a no spark condition. Nobody is sure why, but it has been known to happen.

That's probably the 'auto shut off' function in the TCI operating; remember, if the motor isn't turning (i.e. the TCI is getting a signal from the pick-up coils), after a 'few seconds' the TCI disconnects power to the coils to prevent damage. If you have a clean break in one of the wires (rather than an intermittent connection), the TCI will think it's not turning....

I for one experianced this.

single pick up coil failure

Wow, it never ceases to amaze me the knowledge and experience of all you guys. Once again, I've learned something new about my bike.
Thanks again for sharing all your knowledge.
I love this site.

Well I found a broken orange wire from the pickup coil, what is the best repair?
longer wire connected?
wrap longer wire around bottom of clamp for movement?
or?
any ideas would be appreciated.
Thank you for your time and response.

That soft flexible wire used for electrical multimeter wires works best.
