Re: 1988 750 Paso Loosing Spark
Hi,
The Pick-up coils measure 99 and 99.4 ohms. the lost spark is observed by an inductive timing light and verified by a spark plug. Ive checked the flywheel and the crank there is no issues found with them. It is truely bizarre.

Re: 1988 750 Paso Loosing Spark
Hi, No,Ive hit the wall. All of the components check out,voltages are equal front and rear cylinder, resistance values of the coils and triggers match.Ive replaced triggers. Ive tested and checked wiring and even jumped around the wiring harness to no avail. I tried a new coil today and it did not h...

Re: 1988 750 Paso Loosing Spark
Hi,
My experiance with ignitions tells me the primary windings are typically 5ohm and as low as .5 ohm,secondary windings are around the 11K range.
Thank You!

Re: 1988 750 Paso Loosing Spark
Hi, I greatly appreciate all of the responses! I have a thick skin so no worries on the ribbing! I tightened the spark plug gap to .020" and seem to have a better spark while i have it but the problem persists. I did a compression test and have 100psi in both cylinders.Where this seems low its ...

Re: 1988 750 Paso Loosing Spark
Hi, Truth is that i have not checked the compression because the evidence is in the electrical system. A lack of compression would not effect the electrical system. I use an inductive timing light and can see when the spark drops away. At idle the front cylinder is firing and idles normal. When the ...

Re: 1988 750 Paso Loosing Spark
Hi,
The coils are stock part number and the spark plugs are NGK's Per their application chart.I thought about the gap issue, and widened it to .040"
Thank You!

Hi,
I swapped CDI Boxes front to rear and procured a known good CDI box and tried it with no improvement.
Thank You!

Re: 1988 750 Paso Loosing Spark
Thank You for the responses. I have replaced the spark plugs and wires. The wiring has been checked and additional ground ciruits have been added. As my customer has indicated to me, the bike was running fine and he stopped for a drink break and when he started the bike it was running on one cylinde...

Hi, New Here! I'm working on an 1988 750 Paso that is loosing spark in the horizontal(front) cylinder just above idle. It has spark at idle,but as the rpm rises it looses spark. I have replaced the triggers, coils, swapped in a known good CDI Box, I've swapped CDI boxes Front to rear, I've added add...
