1986 xj700 maxim X

Whats a good set of ignition coils for this bike??? Non Yamaha part? Looks like it needs both. Original on there now, only 12k miles on bike. Thx Mucho

 

Purchase mine from Len at xj4ever.com. I really don't like cheap aftermarket parts and your usually better leaving on the old parts then installing cheap parts in my experience.

I have a 85, I put these on my bike. They match closely to the specs of the oem ones. https://www.amazon.com/gp/product/B08F7VWDZM/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 (

You will have to take the old spark plug boot and put it on the end of the wire, it just screws on. I'm pretty sure on the 86, there is a 5k ohm resistance in the spark plug, not the boot, so make sure to ohm out your boot to make sure it hasnt gone wonky, and replace those plugs while you can.
The above replacement isn't a PERFECT fit. You can get the front bolt in, but coils wont want to slip all the way back without taking a notch out of the butterfly holder. Took me around 10 minutes with a Dremel. This will allow you to just thread a smaller bolt in the end (I used a metal ziptie, not a big deal). Finally, The old coils were soldered on to the input wires, so you'll have to put connecters on. In the end, they go into the bike much easier than the oem one, due to a smaller size, and dont interfere with any of the bits inside like the fan blade. All in all, you are looking at around a 1 hour job, depending on how proficient you are at wrestling the old ones out.
