    1985 DR 250 12 volt conversion ( help! )

    My Instagram is now instagram.com/aaronrecine. DM me and I'll try to remember it and walk you through it. Best option is to get a gn250 and dr250 manual and back engineer the diagrams. I never got it fully working, but I'm sure now with the extra experience I have I can help you out.

    dr350s battery not charging

    HEREEEEE is something realllyyy interesting about the bike. It will still run and function but have dim lights and what not if your 15A fuse is dead. Be sure to check this before anything else.

    1985 DR 250 12 volt conversion ( help! )

    and it works! I ended up reverse engineering the wiring harness along side a wiring diagram so I could hook it up for always on operation without any kill / ignition switch required. The circuit is really simple. the bottom 2 pins of the CDI are the pickup coil. the middle left is + the middle right does nothing. The top left is to fire the ignition coil / spark plug. the top right is ground. To fire it I attached a 12 volt lithium ion battery to the cdi, plugged in the pickup coil, wired up the ignition coil and ran her with carb cleaner as the mikuni is a pile of dirt / rust and varnish paste.

    1985 DR 250 12 volt conversion ( help! )

    welp.. if you are going to do anything do it yourself I suppose. The GN250 stator will fit perfectly in the DR250 engine. Parts for the GN250 are fairly cheap too. Parts needed... 1. Voltage Regulator (~$24) - http://www.ebay.com/itm/271531329667?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT 2. CDI (~$20)- https://www.amazon.com/gp/product/B012ZUXSAG/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 3. Stator with Pickup Coil (~$30) - http://www.ebay.com/itm/171565178165?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT 4. GN250 wiring harness (Used so price will vary) - http://www.ebay.com/itm/131861866599?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT The grand total spent on this bike so far is... 1. $180 cash for the DR250 on craigslist 2. ~$130 on the parts listed above Everything else on the bike is total shit. The handles, brake master cyl, tires, chain etc will all have to be replaced but this should all come out to about another $300-$500. My estimate is at the end of the day I will be at about a grand with registration, the ignition system, wheel bearings, controls, seat cover and accessories like turn signals and brake lights etc. The nice part about doing all this is knowing that the entire bike will be practically brand new by the time I am done with it, excluding the engine and suspension systems.

    1985 DR 250 12 volt conversion ( help! )

    I just acquired a 1985 DR250 for $180 bucks. She needs a lot of work, but has great compression. The pickup coil shows 70 ohm which is well in range. I have no spark because of a dead CDI (pickup / stator / ignit coil all test ok). These old bikes have rare CDI units that are $150+ and also have a shitty 6 volt system. I found through some googling that the DR250 and GN250 of the same era share the same engine. The only difference is the GN250 has a 12 volt system. SO... here is my idea... I can get a stator / voltage regulator / cdi for a 1985 GN250 and plop it into my 1985 DR250. This way I have a 12 volt system, a cheaper CDI, and a fully rebuilt ignition system. Please chime in and tell me to go for it or im an idiot. thanks! https://www.instagram.com/p/BHPyIWIAe9L/?taken-by=theoriginalpumpkin

    XT550 Possible Aftermarket Pickup Coil Solution

    I got the bike to fire over and work, but I did not make a 100% great bracket. I honestly just don't have the time to finish this AND a running 1990 DR350 fell into my lap for $550 bucks. If you were to make the bracket and mount the coils the engine would run fine. It is just a matter of getting the new coils to be EXACTLY where the stock ones are positioned. I was off a little and nearly broke my leg from the kick back (it ripped the bottom of my vans in half). If you need help or have any questions about how fire away.

    XT550 Possible Aftermarket Pickup Coil Solution

    Just wanted to post an update real quick. I just got the 2 new pickup coils in from ebay for the final model. I am going to make it out of some scrap 1/4" steel that I had from a previous project. I'm going to secure the pickup coils to the bracket with high temp epoxy or maybe JB Weld. I will post pictures, videos and dimensions of the final product so you can make it all yourself. Most likely I will start a new thread titled Confirmed Yamaha XT550 DIY Dual Pickup Coil Assembly.

    XT550 Possible Aftermarket Pickup Coil Solution

    100% confirmed!!! The 1982 XT550 DIY dual pickup coil setup that I built works FLAWLESSLY. I kicked her over about 6 times before I got ignition. Here is a video of me putting in the coil Here is a video of me starting the bike for the first time I am so happy that through a little science and hard work I am the FIRST to create a diy 1982 XT550 Pickup Coil. http://www.ebay.com/itm/190883152667?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT These are the coils I used. Mount them as you wish for now. I will post a video of the final construction when I get the time to build it.

    Here it is folks. The last stage of development. https://youtu.be/QTv8GM4WhMY Might put her in the bike today.

    this sounds like an ignition issue. I had the same prob on my xt550. turned out to be the pickup coil. check resistance of your pickup coil. I don't know factory specs, but prob around 80-130ishhh

    XT 550 no spark

    Your problem is not the stator, it is the pickup coil. There are currently no aftermarket options for pickup coils, but I am currently developing a new pickup coil for these bikes. If you look at this topic here, you can follow my progress. I am pretty sure I can get this bike running within the next month (if time allows with my busy schedule). http://www.thumpertalk.com/topic/1183282-xt550-possible-aftermarket-pickup-coil-solution/

    That is a good bit of news about the stator if mine ever starts to take a shit. I looked up the pickup coil and its a single pickup. womp womp.

    yea I figured I would get about the same result. Thanks for the heads up.

    XT550 Possible Aftermarket Pickup Coil Solution

    ALRIGHTYYY!! Made a really decent amount of headway today. I was able to temporarily fix my stock coil (bad connection is inside the unit, but you can wiggle it just enough to get a good contact) to use it as a reference reading for the new coil setup. In this first video I show the diagnosis and repair of the stock coil... I figured out later that the weight of the new wires pulling on the cables was enough to engage the contact. Sometimes it is totally great and clear and sometimes its just garbage. In this second video I show a comparison of the scope readings on the stock coil (after repair) and the new honda coils. As you can see the readings are nearly identical (minus the 2 peak signal on the right scope which I believe to be the coil picking up both magnets. I didn't clamp them with much care, just wanted to compare readings) so in theory once I create a bracket this should work just fine. Things are really coming along and I am fairly confident that these coils will work just fine. The only worry I have is the signal being to small, but if that is the case I could make a small amplifier that boosts the signal (also thought about using a microsecond delay circuit to change the ignition timing, but lets not make this system more complicated haha).

    you must not have tried very hard because it is all over google. Wayne Gum on ebay sells a direct replacement. http://www.transmic.net/en/home.htm this is how to build it. http://www.transmic.net/en/home.html Please look through the forum and google before posting an unrelated question into a different thread.
