Re: Coil

Kudos to both of you. Cut the CDI power wire and ran direct to the battery. Immediate improvement. Power is back and the bogging is gone. Fuel obviously being combusted. Only rode a few miles, temp here today is 102°F, looking at 103°F tomorrow. So battery, CDI, coil and hall sensor eliminated as pr...

Re: Flywheel Follies

Enjoy seeing your work, especially the tools.
Curious, if that is a tapping head, when the tap reverses what keeps the nut from lifting out of the socket?

Re: Coil

Claus, the NGK plug boots have a built-in resistor, almost 5k Ohm in each boot. The plug wires are stranded copper. I was happier with my 2002 Ural ignition. Also better engine, except for the cam bushing. The 2002 ran rings around my 2013 GearUp . I'll see if a local automotive electric shop will t...

Re: Coil

Agree, new doesn't mean good. To clarify, the 2.09k Ohms is the secondary only, meaning the plug wires and boots were removed from the coil. With the plug wires and boots included the total was 11.5k Ohms, about the same as John. The OEM coil I replaced shows similar values. I don't have an o'scope ...

Re: Coil

Claus, The battery reads 13.0v before switching on the ignition. I assumed the drop is due to the headlight and a digital voltmeter located in the sidecar dashboard. With the ignition switch on the battery reads 12.45v.

Re: Coil

Have 12.3v to the CDI. New battery 12.45v, new CDI (unused, purchased from Heindl), new coil, new Hall Sensor, fresh plugs, cleaned and tightened ground connections, added ground wire from battery to engine/frame top mount. Still have puny yellow spark, fouls plugs in less than 20km. Problem started...

Re: Coil

Chasing a weak spark problem. I'm seeing 11.5k Ohm plug boot to plug boot and 1.3 Ohm thru the primary winding. Taken apart it's 4.7k Ohm for each boot and 2.09k Ohm for the secondary winding. I've gone through the other ignition components, battery, CDI, Hall Sensor, ground connections and haven't ...

Coil

2013 GU Ducati CDI ignition.
Anyone happen to know what the primary and secondary winding resistance should be?
If not the specific resistance how about the ratio?

Re: Driveshaft rubbing wheel

cjlyth,
Take a look in the "Videos & Best of How to do posts". On page 3, Albuquralque has a couple videos covering re-spoking and tensioning.
I use a bench vice, my rear axle, a dial indicator and a torque wrench to true the wheel. Takes time but worth the effort.

Re: Cylinder Removal - Stuck/Hard to Remove

I haven't had trouble removing cylinders. Sometimes just a tug and they break loose. If not I've used a dead blow mallet with a resin head to gently tap the cylinder until it separates from the base gasket. If you're still having problems with it, check out Gobiums Lemoto site. In the tools section,...

Re: Hall Sensor

Did not start it before modifying the spacer. I have been chasing an electrical (ignition) problem for some time. Loss of power, fuel not being fully burned, fouling plugs. During the installation of the new sensor I saw the disc rubbing the housing and thought might be the source of the problem. Un...

Re: Hall Sensor

Not a difficult fix. Gap in sensor, between the magnet and the housing, is .090. Interrupter disc thickness is .038. The disc was just touching the housing so needed to move it out about .025. The spacer that positions the disc is .590 long so I turned a new .615 long spacer. Used 3/4" 303 Stainless...

Hall Sensor

Replaced the Hall Sensor this morning. 2013 GU with OEM Ducati ignition. Didn't pay attention when I pulled the old sensor but with the new one it appears the interrupter is rubbing the sensor housing. Took a look at the old sensor and see obvious rub marks. Question, has anyone shimmed the interrup...
