Anyone tried... (CDI)

Got questions? We got answers....

Well, my new Ricky Stator source coil really cleaned up the issue I was having. The new coil read 385 ohms, compared to my old coil (171 ohms). My bike pulls very hard at high revs now. I still the Dragonfly CDI coming, though, and I will update this thread when I get it installed.

I received my ignition today, from Mike. It came from Ecuador. I will try to get it installed in the next couple of days and let you all know how it performs.

I finally installed the "Wolf Pack" ignition last night and just now had a chance to try it out. The installation was fairly easy, and straight forward using the diagram supplied on his website. I opened up the ignition and removed both the "A" and "B" jumpers because I wanted the ignition set up as aggressive as possible.
Mike was very quick to answer my questions via e-mail, and when the package arrived from Ecuador, my wife raised an eyebrow...
The difference in power delivery is quite noticeable. The motor revs out very far and likes to be there. The motor seems to rev much more quickly, and low and mid range power does not seem to be diminished at all, and in fact, it seems a bit stronger.
I will experiment further with jumper positions, to see what kind of impact they have on power delivery.
Overall, though, the $70 was a small amount for an "adjustable" ignition module.
Thanks, Mike!

It is a "shorting" wire from the kill switch. Just tap into the green lead on the WP CDI (from the source coil) in a "Y" configuration, to short the source coil upon hitting the kill switch.

well after getting my kx front end on my bike I decided i would put this cdi unit on. I first rode the bike around with the stock unit. i then put the wolf pack unit on. Without playing with the jumpers it was noticable by a bit. played with jumpers and wound up just leaving them off. This seemed to be what I liked best. The bike just revs better and pulls better . I would deffinatly recomend this to anyone looking to get more performance.This was on a H series bike by the way.

Yep. I agree. I have both jumpers removed as well. The bike hits noticeably harder off idle, and revs out harder and further.

My Wolf Pack ignition experienced a problem today. My bike started running very poorly, with only the low end running cleanly. There was no top end accessible at all. As I started to limp towards home, the bike suddenly got very bad, and would barely run at all. I barely made it back.
Once I was back in the garage, I took the cover off of the ignition pack and found a that the 1 1/2" long black jumper wire had broken off of the PCB at one end. I removed the module for now, re-installed the OEM ignition, and will attempt to repair the WP module later.
With the the OEM ignition module installed, the bike still would barely run at low speeds, but would rev well. ?? I kept digging, checking the most recently replaced items first. The Ricky Stator source coil checked out fine, so I left that alone. I had just rebuilt the top end, and I was starting to suspect mechanical top end issues, when I decided to check the reed cage before I went too much further. Bingo! I had sucked a reed! The V-Force 2 reed cage had a missing reed. I found 1/2 of it, but the other half is AWOL. I re-installed the OEM reed cage and everything returned to normal.
So, IMO, the jury is still out on the ignition pack. I will see if I can repair it (the repair looks fairly simple, but I need a solder sucker, and a precision soldering weapon). Right now, I am thinking about filling the whole thing in with silicone once I get it repaired. Since the OEM units on *all* modern bikes are filled in with potting material, this seems to be very important for an electronic device that is subjected to heavy vibration and jolts that a dirt bike dishes out.

i have mine mounted in foam. I also put shoe goo around the board when I first got it to help. I have had to do this with expensive gyro systems for my rc helicopters. Having a little bit of electronic experience I don't see any issues with the unit. I am in the process of making a couple of these units myself . One for another guy in the area and an extra.

I have made 2 so far but I gave them to other people. I just haven't had time or reason to make anymore. I can't really commit to making one right now. If you don't need it anytime soon hit me up again and I will see what I can do. The one from wolf pack works fine and with the mods I did just make it more reliable from any vibration

Ok, I'll no doubt get flamed for this, but here goes. $55 (and that price includes postage, right?) is an amazingly good deal for an adjustable CDI, and the seller seems to provide very good customer service as well.

Please don't rip off this guy's design for your own profit, and please don't post up the schematic. This guy isn't getting rich off such a small market, he's an enthusiast selling a clever product at a dirt cheap price, pretty much for the fun of it. Why steal his design to save a few bucks? How would you feel if you were him? It'd be different if he was charging $300 or something, but come on.

I'm an electrical engineer, I could buy one of his and have the design figured out in about 5 minutes and start building them. I'm not gonna do it, I don't have the lack of ethics the Chinese do.

By the time you build and troubleshoot your own, how much time are you going to have in it, especially if you're not a EE? Probably several hours, maybe you get to push the bike home sometime when your homemade version fails. Give the guy a break and support his innovation by buying his incredibly inexpensive and clever CDI.

Not flaming you but I do disagree that it would be ripping off his design. If you are building it for yourself, not for resale, then there is no problem. Now, if I was planning on making them for resale at a profit then I can see an ethical, and possible legal, problem with that. However, that is not my intent and being here on KDXrider, the best place to sell such an item, you guys would know if anyone was trying to screw the guy over.

Anyways, I have built many electronic projects from known commercial designs over the years. As a musician this is done all the time for effects pedals, pre-amps, and even amplifiers by regular people. If it wasn't legal to do so I'm sure companies like Ibanez, Morley, DoD, Marshall, etc would put a stop to it. Also, think of the majority of products on the market that you own. Do you seriously think American companies (forget China!) don't buy their competitors products, reverse engineer them, and implement parts of the design, or improved versions, into their own product? Sure, they change it just enough to not legally infringe on the intellectual property rights of the other company but come on! You honestly think Kawasaki, Honda, Suzuki, and Yamaha, haven't done this? How about Ford, GM, or Chrysler? And the list goes on! It is a common and accepted practice throughout the world since the dawn of time. The only reason everybody singles out the Chinese is because they are blatant about it and copy a product right down to the user manuals and packaging which is unethical!

Uh, it looks like that is the case with the original version as well since we have already heard of one failure from gregp. I personally would like to see where I can improve upon it like osobad has and maybe my soldering skills are just a little bit better than the guy would made them!

Yep, they do, they BUY the competing product. If you want to BUY this guy's CDI and use it's design to build your own, improved product, and even offer your improved design for sale, by all means do so....but BUY it!! Let the guy make a few bucks, just by holding it in your hand and testing it, you'll save a lot of time on your own design. In fact, that's exactly what osobad did; he BOUGHT the product, then improved it. I'm fine with that. Just please don't simply steal the design from a posted up schematic. That's just not cool.

our tool and die shop has a cartoon up (i think its dilbert) where the boss comes in and says they liked the "promo" very much and they sold 1000 unit of them
to which the guy replies "it is not ready for production yet...it is just the competitors model with duct tape over the logo"

I was going to respond to the ss109 to go to dragon fly75 and look at his schematic and what he did. Then I see some post requesting that I not move in on someone elses product. Never intended to. This is not my design and I don't want to build these to sell If I did make one it would be to help someone out not for my gain.I am always willing to help people when I can . I do this in every hobby I am envolved in. I think the 55.00 is very reasonable from wolf pak and he seems to be a stand up guy. I made my own to have backup but wound up giving them away to people that needed them at the time. I am a person that loves to tinker and do it with many things. Yes I did see a need, my opinion only to make some changes . weather needed or not. I never said they were needed just that this is what I had done to make it more reliable in my mind. I gave this info as maybe some ifo that might help others . This was done to possible calm fears that it was not a worthwile product. What I did was very simple and easy. If members here think I am trying to step on someones toes it was not intended. I have enjoyed getting info from this sight and was just tying to share some back.
