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.

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.

Thanks, I just took it out for a test run. Definitely feels stronger. I think my old coil was on its way out. Last two rides I made the engine cut out briefly and only did it once each time. It did this while just cruising and not under a load. had me puzzled.

I think the stock coils are prone to heat soak issues as well. Plus they aren't the strongest spark producers to begin with.

One of the reasons I bought that 3 wire coil - which I just got in the mail today - is because I think my coil is starting to go out too. Cold starts are starting to get harder, and like you mentioned, it doesn't run as smooth as it used to during those cold starts. I know it isn't the plug lol.

Just got back from a 53 mile ride. The new coil is definitely an improvement over the old one.

I might try to support it from underneath, if what they say about breaking plugs is true... I'd think one cannot give it too much support.

The brackets pretty stout. It's not going anywhere .

[Tashka]

I think this one would work, but I'm not sure.

Would it be beneficial to just change out the spark plug? im running a champion brand spark plug. i bought the cheapest one they had for my bike when I first got it, as I was trying to get it to run when I bought it used. so I've had it pr9banly 1000k miles or so? maybe 2k, my stock speedometer broke and i haven't set up the aftermarket Speedo yet, just the tach9meter.

[JerryHawk250]

Those look like the same ones. Not sure you will need 8 unless you're planning on slapping a V8 on it.

It wouldn't hurt to swap out to a NGK DPR8EIX-9 Iridium IX Spark Plug.

Another thing you want to do is check and adjust the valves if you haven't done that yet. Just about all these bikes come with the valves set too tight from the factory.

[Tashka]

I've adjusted thr valves already, they were set quite tight. But yeah it's not hitting thr rev limiter. it's weird because this is a new issue, starting only this week. I rode a sustained 60 for about 45 minutes, everytime idgo right above 7k, it would start misfiring and i could feel it jerking, take it back to 7k ans it's okay. at first I thought it was jetting, but it is fine full throttle up until 7k

[JerryHawk250]

what size main jet are you running?

[Tashka]

I'm running a 112.5 right now. i was running 115, but when running a long time , itd bog down real bad at full throttle. i had to stop like 4 times on the way to an off-road park after extended 55 mile runs. I haven't had the same bogging down issues on this past long rude.

it just doesn't want to go past 7k anymore, even in lower gears. it just starts misfiring almost like hitting rev limiter but more bouncy.

My co-worker said that the loose head gasket could be causing me to lose compression and cause thst misfire. He noticed it when it was super minor, and it's worse now.

What do you mean by loose head gasket? If the head gasket is leaking then there's your problem. Have you done a compression test?
