- Digging deep into a DRZ400 no spark issue and narrowing things down to bad pulser coils (crank position sensor / pick up coil); on three brand new stators & pulser coils from reputable Canadian companies. Should we bother buying domestic products or move onto cheaper international supplies?

![HOW TO TEST A STATOR / WHAT IS A STATOR [step by step] GY6](http://i.ytimg.com/vi/VoXYzQ61tRM/mqdefault.jpg)
I have had issues with RM stator as well. Where a regulator/rectifier was not preventing over voltage at high rpm. They did eventually accept as a return.
it will WORK the usual problem is the trigger coil is too far away from the magnetic rotor .bring it in closer , or the rotor has LOST magnetism simple?
I tried 2 new stators and my bike charges but wont rev up. Please advise. Please
Please. I really miss my fun bike😢
I swapped the blue and green on my aftermarket and it sparked better but wouldn't run. I also heard to switch the black and white as well and nothing happened. So I went back to original and it still has little to no spark. Someone help me
So my cheap ebay stator that won't give out spark is testing at 550 ohm at the green and blue wire switched them around still no spark.. I'm perplexed..
Hello, just a quick question, if you got three yellow cables going from stator to rectifier, can these be mixed in between? Does it make any difference? Because i had to change the connector, and lost which one is which, thanks in advance!
I watched a video from Bennets Bike Social on here, about chinese copies of uk specialist motorcycle parts. It was a real eye opener as to how the cheap aliexpress etc parts look identical, but can be incredibly underperforming and or out of spec and or ill fitting/finished.
As you said in the vid, no problem on expendable parts like mirrors etc. . but I'd be hesitant now to put anything that 'matters' on my bikes.
And as for gopro, they are utter junk. Every new model seems less useful and has more issues than their earlier ones. Victims of their own success?
Thought provoking and interesting video lads, cheers.
Hi have just bought a ktm 525 of a friend.. Was running until another bike hit him on the flywheel... The bike stopped running.. He thinks it needs new stator.. Iam hoping it is just the sensor or a split cable... Any ideas
Can't wait to get the bike for a look
I noticed when you checked the resistance, your fingers were touching the leads, that could be a contributing factor in a false reading?
I have a factory DRz 400 Stator you can have.
It stoped charging but the bike still had spark.
I just tested the Pulser coil and I get 483 ohms.
You might be able to make it work.
It’s free if you want it.
I live in East Chezzetcook NS
I'm going to forward this information to Jeff. Thank you for the generous offer.

Have you tested resistance of the oe stators including the one that was previously replaced prior to the kimpex one? What reading do you get? Is it possible to wire in the "pulser" from the original into the kimpex part? Barring that, I would recommend you just go buy a replacement from Suzuki.
No the Owner binned the old stators before I could get my hands on them. My first idea was to scab the Pulser/pickup coil from the old stator if it was good. He now knows to hold on to the old part till the new one is installed and running and sometimes even then! ;) I have tested the Stator Pulser/pickup coil and Signal coil in My DRZ400 as a benchmark and it is within Suzuki specs. That’s part one of this DRZ project and should be up on the Garage channel this weekend.
Ok my bad you answered my 2nd question haha thank you.
i would have ate the shipping cost and went with Ricky Stator. They are the best. I have not looked, but I'm going to see if you followed up on the issue. My buddy crashed hard and now he has no spark. I'm working on diagnosing his stator.
Hey Dewey, Colin here. This is the playlist you are looking for. th-cam.com/play/PL0Pb8DdEPgb_VGSULi91Sn5X3cDO6K1Zc.html
Resolution did come but I won't spoil anything ;p
@@TTADV Thanks a lot I actually looked around and found it myself
Wonder if they are just a bad lot.
I have a 2018 Drz400s 15000kms on it,its stuttering for a few secs about twice a day now,just wondering if its the stator on the way out,im runnng a NGK iridium spark plug.
Any advice would be appreciated?
Hey Joey, that could be a ton of different things unfortunately. I'll link you over to the Trail Trash Garage Channel and Jeff's latest DRZ400 video if you want to reach out to him! th-cam.com/video/QJRK9ded31w/w-d-xo.html
Switch blue/green wires, I got no spark after stator replacement, I'm afraid I do got a chines one. Can I just switch the wires and try?
@TrailTrashGarage Thoughts on this Jeff?
I have one on it's own that measures 207ohms. It's for a Yamaha SR250 motorcycle. Could it be okay?
You would have to find the specification for your specific bike, but 200ish ohms seems to be common.
Wow. So disappointing. I have a drz 400 2001 and I love it! But I’m going thru the same thing. Why can’t we find a generator that fits our bike? Why is this so hard? The mechanic that currently has my bike said my bike needs a cdi and a generator and hasn’t been able to find either and will give up in 10 days if they can’t find these items. Crazy I know. I’m thinking of just buying a used drz 400 all over again. Seems easier than finding parts for it.
I’d like you to test a stater right out of a good bike and see what it measures. ;) this will be the true test.
Do you trust that meter ? It looks like a $5 Minimart meter. Doesn't mean it's bad necessarily. But looks cheap.
He confirmed with multiple meters of various quality and from different manufacturers.
Any DVM (digital volt meter) is only as good as the person using it
I have spark, but no ohms to the pickup coil. Do have ohms to the charging coil.
Hey Craig, I'll link you over to the dark side and Jeff's Garage channel, he will likely be able to provide you some more insight if the videos don't answer your question: th-cam.com/video/QJRK9ded31w/w-d-xo.html
@@TTADV appreciate it. I already took the winding off my pickup coil to the stator. My pickup coil is part of the stator, so I'm going to have to get wire and wind it and epoxy it myself and hopefully get 170 ohms. The oem stator is a hard to find part for my 1996 ktm 250 sx. I had no continuity to the pickup coil, so i think its still sparking, but not timing right with the bad pickup.
I am running into the same issue with my 03 DRZ400S. My previous (original) stator was not charging my battery properly. (less than 12.5 volts), I swapped my stator for an RM stator and now I have no spark also. I also tried swapping the blue/green wires and still nothing. I also tried swapping the black and white wires, also nothing. I am having the same confusion as you regarding the pickup coil. My manual states 390-600 ohms is acceptable but the RM Stators pickup coil measures 214 ohms?? Just wondering if you ever got anywhere with this? To make things more confusing I actually reinstalled my original stator and now still have no spark? Could I have damaged the CDI in the process of swapping wires? Thanks for any info.
Hey there Jason! Jeff did end up figuring this out! I'll link you over to his latest video on this. I'd copy and paste your question in the comments section once you're there for a speedy response from Jeff. Kindest regards, -Colin th-cam.com/video/QJRK9ded31w/w-d-xo.html
I'm having the exact same problem
@snakevale198444 so I actually found the problem wasn't the stator at all but rather the idiot installing the stator (myself of course). The pickup that gets installed on the cover can actually be installed backwards, meaning that the pickup can get installed so that the pickup no longer lines up with the magnet, and your stator doesn't actually think your motor is turning over. I had to take it apart 3 times after noticing thus really dumb mistake. I reinstalled the pickup correctly and boom there was spark.
@jasonjanzen7189 oh wow.. looks like I'm taking the cover off.. was it like upside down.. or not properly lined up.. I didn't think there was much room for error..
@jasonjanzen7189 I'm getting 550 ohms to the green and blue wire from the ebay stator.. brand new battery.. I know it's the stator because my flywheel bolts snapped and took mine out..
I'm having a hard time with mine. It stutters at full throttle and is very hard to start sometimes. I have no clue what could be the issue but my mechanic thinks it's the stator. I bought my stator and regulator from mad hornets everything works it just stutters and hard to start. Any suggestions please? I've been stuck on this for a month
When you changed the Stator did you change the pulser coil. Have you tested the ignition coil? What makes you so sure it’s electrical?
@@TTADV yessir I used the one that came on the stator. I used a 100$ kit from mad hornets. But what points me to being electrical is my mechanic went over valves (they were spot on) timing (spot on) and cleaned and rejetted my carb because it was off a little bit. None of this started happening until my old stator and/or regulartor went out leaving me stranded. Thats when the stuttering started and hasn't went away even tho I fixed pretty much everything that could cause a problem like that. Unless it could be the coil under the tank? I've read forums, watched videos, made post and I can't get pointed in the right direction. Even my mechanic is stumped but he's pretty sure it's the pulser coil as well
I feel your pain. I got 2 kits. with 1 it wont start. With the second it starts but won't rev up))))))))))@@evandavidson1651
Any solution please?
The amount of BS-ers out there is mind blowing. Foreign or Domestic, is one in the same.
