The connector for it cost more than the coil itself. Go figure lol

Does it have standard spade connectors on the coil? Most all of my bikes have standard .195 and .250 spade connectors on the coils and I rarely have problems with corrosion on them. I would use the proper connector on those COP coils.

It has round pin connectors.

Coils in general tend to be expensive. It might be worth hitting up the pick-a-part to get a coil and connector for a better price.

You can always spring for an AEM CDI Pencil coil (30-2854). $80 on Amazon as a complete kit with connector, pins, and seals. $71 through Summit plus shipping.

This is the coil I am waiting for in the mail. It alone is $48, and another $7 for the connector kit. https://www.diyautotune.com/product/...ischarge-coil/

I took an extra day off this weekend, so I am hoping to squeeze in my ignition pickup advance experiment so I can give that a test before I go trying to hot rod my ignition coil.

Just ordered the coil and connector for under $19 from amazon. Should have it for Saturday. I plan on the ignition pickup advance experiment myself.

This a slight bit off topic. All this coil talk is going to help me out on an upcoming project.

I know there are a few companies that put out high output coils spec'd for bikes that put out more than 30,000 volts to the spark plug. Accel is the main one or most popular, I think. If I'm not mistaken, most Japanese bike coils put out 10,000 to 15,000 volts. The high compression FI bikes might be 20-25,000 volts. The spark plug wire(s) are the common failure point on most bike coils. If my V Star coil wires fail, I'm screwed as they are connected internally to the coil. The wire is not replaceable. When I do all the mods to my V Star, I'll have to use an aftermarket coils. COP coils aren't an option so I'm stuck with aftermarket coils. I think I'll need at least 30,000-volt coils on the V Star when I'm done.

I am waiting for the results of your experiment with ignition advance with great anticipation. The next step in power production from this engine will be achieved with variable ignition timing. I know how to do this mechanically, but not electronically. There should be a way to control the timing of the condenser discharge electronically. Maybe to delay condenser discharge at starting and idle, and gradually reduce the delay until 3500-4000 rpm when the delay has been reduced to zero...ARH

will this hot spark idea be significantly better than simply changing the plug(s) to brisk brand? i havent come across a plug that made a noticable difference in my projects until i was introduced to a brisk plug. i could tell the increased power, no misfires in any rpm range, and durability at the very moment i fired my first one up.

What plug did you go with? Brisk sell a few different types.

my last three were for a 125cc lifan:

prior to that is was for the 250 hawk:
cant find link now. magnum tuning is helpful in email or phone to cross reference for you. don't trust forums for cross reference with brisk plugs.

prior to that was for a bmw 3 series.
i swear by it....these alone will make a difference behind the wheel or handlebars....if you do this mod first you will notice the power increase, maybe not so much if its the last mod you do, but since its a huge noticeably stronger engine upgrade from stock setup.....i am hooked

Thanks. I cross reference the ngk on there website. It should be this one. https://www.amazon.com/dp/B00NAGWVT4...v_ov_lig_dp_it

just a note:
when i got mine in, i placed the china stock torch brand next to the brisk.
i noticed the brisk would end up intruding the hole deeper into the chamber, it was just a little longer but worked perfect. i guess they are supposed to be longer for the technology to work. it wasnt a mile longer but just enough to make me pay attention to not bottom out on something in the cylinder....i am just mentioning this if anyone re-thinks inserting this into the cylinder head... it is supposed to be a smidgen longer than stock. well at least in my projects....sorry if i hijacked the plasma fire here.....i am sure plasma is better , but how much better....

The stock cdi timing curve already has a gradual timing advance from 1500 to 4000rpm. All I am looking to dois advance the pickup a couple of degrees to shift the whole curve up.

There is a programmable CDI out there. That's another project somewhere down the road. Can't do all the mods at once. I need to spread them out to keep me occupied on the rainy weekends.

That's one of the things I really appreciated about the early Honda XR200 motors; they had a centrifugal advance mechanism and CDI that was quite similar to the small black Chev design of 1974 to 1986.
