Mike's Green Coils
I've searched on here but really can't find anything. I see where there was a longevity issue with the black coils but I can't find anything about that with the green ones.
Educate me please?

The problem I had with the Green ones is that they act like rev limiters. I could never get Betsy to push past 8K with 'em, and I think it's because they have so much voltage. They put out 45Kv at 12.5V input, and it goes up to 75Kv with 14.5V input. I think they just sucked more power than the system could supply. But then again, I had a slide needle issue too, so that probably contributed to the problem - if not outright causing it.I think I have a loose screw behind the handlebars.

So, did the Dyna's fix that or the carb repair?Originally posted by dbeardslee View PostGreg

Betsy took a four year Rip VanWinkle type nap, and when I put her back on the road earlier this year I went through the carbs and replaced the coils. I had a stutter at 3.5-4K and it wouldn't push to redline, and having just fixed the identical problem on my brother's XS I checked the slides. The needles that were installed didn't have any markings on them, but I had a set of 5GZ6's in my stash, so I swapped out the needles. After that she ran like Hillary Clinton from a room full of reporters.Originally posted by BA80 View Post
What I think you will notice first on the Mikes coils, as you will with any hot coils, is the cold starting. It doesn't take much to start - basically just a tap on the starter button. With properly working coils you'll also get better throttle response. They definitely make a difference.
I wouldn't trust the Green Monsters long term, but they should give you some insight on the difference hot coils make. And if you like what you see from the Mikes coils, slap some Dyans on there and you'll REALLY like it. I think the 45Kv is just too much, but the 30-35Kv that the Dynas put out is pretty much perfect.I think I have a loose screw behind the handlebars.

And one other thing - if you make up high tension wires for the Mikes coils, you can use the same wires on a set of Dynas. And I saw one seller on ebay that had new Dynas for $118 without wires, so that could save you a few bucks.I think I have a loose screw behind the handlebars.

I haven't yet had any issues with Mikes Green coils in 10000 or so miles. Although with the slight difference in price I would just get the Dyna Coils.Nathan

Already got the Mikes coils, just wondering if I can trust them if I install them.Originally posted by natemoen View Post

Hey Greg,
I'm pretty sure that I read from at least one of our members that put the Mikes Green Monsters on that they also died. They are Dyna Clones, but just that clones....and they do NOT come with any warranty whereas the Dynas have a 1 year warranty, I think Accel has the same. YMMV.

Understood, but one isn't a good basis for judgement. There has to be a better representation than "maybe one", but thanks TC. I know there were several years ago that seemed to swear by the green ones. I can't find anything negative about them. I was looking for something like what Nate came with but with more use on the coils. I had ridden 10K miles by august this yearOriginally posted by TopCatGr58 View PostGreg

I just did a search, found that Fredintoon's son had one go bad on his 650, and another member VGdonivich or something like that had one go bad also.
DB had reported a problem a while back but wasn't sure if it was coils or carbs, but I think finally found it was carbs.
Glad to see that Nate has been able to put 10K miles on them, there were several members that decided to put them on their bikes after reading DB's review, Terry/TW1980 or similar, and haven't seen any of them report any followup failures? SO....the green ones may be made by a different manufacturer than the black ones, and so possibly better quality.
With your propensity for long trips, you might want to be sure you have a pair of those VF1000's in your pack as backup replacements.

My thoughts exactly except it would probably be a set of H stockers. Everybody already gives me a bad time about how much crap I pack.................unless they need something.Originally posted by TopCatGr58 View Post

I don't recall ever giving you "crap" about stuff you bring on trips...Originally posted by BA80 View PostMy thoughts exactly except it would probably be a set of H stockers. Everybody already gives me a bad time about how much crap I pack.................unless they need something.
Just when you leave some of that "crap" that turns out to be vital at 14,000 ft. back in Wichita... and costs us 2 days in Durango...

I'd pack the VF1000's BEFORE the stock! Less room, and they WILL work..... I've been trying to get through a problem that is part coil, part carb..
