[@639Beaver]

I get the distinct impression you are an honest mechanic. One of the las of a dieing breed. Thanks for info. Liked your frankness, and detailed explanation. Son of an honest mechanic, Thank you.

[@gawdammitguru]

Great info bud! Appreciate it VERY MUCH. I've worked on metric bikes/atvs for about 36 years now, and this is a new learning lesson for me. Thanks again.

[@josephrodney7941]

I like to the point information on what I am looking for. Its nice ti see a fellow mechanic who knows and understands time is precious

[@carlosrobles2048]

Well MR.D-Ray, you damn sure saved my day! Great video. Right to the point, well spoken and just great all around. Thank you so much!

[@jamespayne2677]

I tell you what this video was the most informational and easy to understand what he was talking about and what I liked most about it is you did this with quickness. Thank you. You helped me with my issue considerably. From Tulsa Ok.

[@DRaysShop]

Thanks for watchin', I wish I had more free time to do more videos, I actually have quite a bit of footage shot for other projects but just don't have the time to edit. With deer and duck season upon us, I work out in the shop sometimes till late at night. But I cant' complain about the money though! lol

[@dieterronsberg5970]

Perfect. That`s how explanatory vids should be made- straight to the point with some hints & advices along the way. Keep `em comming dude!

[@rogereads6894]

My Arctic Cat 400 has been sitting through the winter months so I hope the starting issue is just a gummed up carb problem, but if that doesn't fix it then I'm glad I saw this video. I'll check the fly wheel. Thanks.

[@donnydenfeld2394]

Thank you. I have one that a customer brought in. Cleanes the carb. Started right up, but couldn't keep it running well. Finally quit and pulled the plug. Absolutely no spark. So I'm gonna go after that flywheel once. Thank you again.

[@WheelsnThings]

Great video man! I've maintained and repaired motorcycles for many years and must say that this is the first time I've heard of flywheel magnets coming loose!

[@helenelalonde7959]

did on mine cost me alot of money before we found it was the trouble..still not working so have to do this check the flywheel...

[@nathanieltabbert6782]

Great explanation. Stopped me from tearing into it once he said I needed a special tool.

[@dg98adams]

D-Ray, I have saved your videos since I have a Artic cat 400 (previous owner changed the flywheel), and a RZR 800 (future top end rebuild)... great videos.

[@SuperCyril2]

Thanks. My Eiger was running poor. Engine missing, running rich fouling plug an overheating my engine. Exhaust header was cherry red. Bad spark was the cause. Took alot of diagnosis before I found out the flywheel was the problem. Thanks sir for sharing this information.

[@coreychapman2921]

You are the man I just love watching your videos You've helped me out on two different things you help me out putting a water pump on my Mercury outboard and help me put my stator and flywheel on my 2004 Arctic cat

[@ryan_riffs]

struggled with one on my lift all day today! they had it at another dealer and that dealer went through the carb twice and adjusted valves. I spent a good part of the afternoon finding the right jets, which werent in the carb and also trying to find the right needle. well i got the carb for sure sorted, re-checked valves and boom, no difference. i pulled the cdi box off a diff 400 and it ran for about 15 seconds and died. so tomorrow i'll have a look at the flywheel, thanks!

[@cedarslopestudio974]

On my 86 Bayou 300 the flywheel just fell apart and made a big mess inside the cover of ground up magnets. Took me forever to figure out my information problem. Good video, I just needed to see what the inside of the cover looked like. You can normally buy specialty pullers for each four wheeler model for like $10.

[@SuperTony26]

Thanks from Canada! Excellent video. helped a lot.

[@jasonrobinson8488]

This guy is great! Very informative and explains things very well, good job buddy!

[@padraiggalvin2807]

Hey. From ireland here. Really appriciate this video. thanks for passing on your knowledge

[@markhiggs5896]

thank you for posting this. 👍 My atv has been running rough intermittently and after seeing this video I’m 100% sure that’s the same problem with my 2002 Arctic Cat 375.

[@vzvxfy]

this saved me lots of time and work trying to figure out what could be wrong. this was exactly what my problem was. thanks!

[@brandonthekodiak2391]

GREAT INFO! Great video i have came across mini of these on suzuki and arctic cat 400s.People sell these atvs cheap because they cant figure out the problem.

[@moocahdasame8812]

Excellent info and presentation.

[@markswick4504]

Great information , I learned that on a arctic cat 250 . I purchased a used one, I know what you’re thinking, yeah going to do the same thing. Absolutely right, unless you go ahead and clean the used one really good, then you get some marine epoxy and apply around each magnet and in between every magnet. When it cures , you’re ready to run, and can feel confident, that you won’t have any issues. The epoxy to use is the white marine epoxy, I know west marine carries it. (Can’t recall the brand, but it’s great stuff!! ) Thats just a way to save some money, and it works 👍 Thank you Ray 🙏 about to do the same thing on a AC 400 , I was thinking about the flywheel, but after your video, that was a great refresher course . Thanks again Ray ‼️🍻

[@DRaysShop]

Thanks, in all the years I've been around bikes and atv's I've never seen this before, but from what I've read, it is pretty common.

[@nadaone82]

Great vid. I had exactly the same problem. Fouled plug, yes, but other issues also. Poor charging, and low amp battery draw when not being ridden. Depending on the age of your machine, you may want to replace the pulse coil and stator also. I did all 3 components along with the voltage rectifier. So a total of 4 items on the charging system. You definitely want to go on eBay & get the flywheel pull tool, it’s around $55. But you gotta have it.

[@melaniekozial2062]

Great video D-Ray. I had this exact problem in my cat 400. Thanks to this great video I was able to solve it. Thanks

[@bobjay9834]

Thanks for the same of knowledge about these 400 cats been fighting mine for awhile.

[@TheJhine5588]

Great video. I have a friend's 03 400 here now that I was just going to get into the stator on. Glad I seen this. Good to know that the Suzuki has the same motor as well!!

[@kenhulse5191]

thanks. I have an ignition problem on mine. I had heard about the Magnets coming loose. Apparently it's not unusual with arctic cats. It was good to be able to see exactly what this looks like though. Thanks for showing it to us

[@camaro69green31]

Awesome info thanks. Just picked up a AC 400 FIS 2005. Saved this video in case I have issues in the future.

[@tonyyack9668]

d-ray, your a good guy to mention about pulling the flywheel, had the same problem & learned the hard way. thanks for being honest..

[@dynodon427]

Today is 4/6/13. My neighbor just rought over a 2006 Artic cat 400 atv. No spark. Checked the fuses, all good. Got on line and started looking, found your post. I'm going to pull the case and look at the flywheel. This is a very informative video, Thank you. PS I just subscribed.

[@simpleman6867]

Well spoken and straight to the point!

[@maryherrin678]

Awesome info, that is exactly our problem & you were very thorough, thanks

[@Treybotoo]

D Ray, you're my hero. This is probably is what I've been having trouble with. Thanks for the vid man.

[@dustinneal1209]

Thx for the update I just got one of these it’s a 2009 model Just needs carb cleaned, It’s a fixer-upper but looks nice

[@philiproark3102]

For the past month iv been going over my 03 z400 s ignition system w fine tooth comb,...replaced stator regulator and about to do cdi..but i bet you a nickel,this is my problem..THANK YOU

[@stevelongley7737]

Thanks for the advice definitely a good spot to start at!

[@larrylueck2978]

Great to see someone explain it .

[@danellsworth3891]

Thanks for the tips on the puller!! Great video!

[@zummy4429]

That was well versed ,very descriptive and right to the point. Great job I wish you did ALL REPAIR videos for all bikes 4 wheelers!! Lol great video

[@lawnboy81SMS]

Yep, I know about that. I work at a campground that had probably around a 2006ish Arctic Cat 400 4x4 Automatic (red) that had quit working. And unfortunately, the people there took it all apart, and had they not taken it apart, the Warranty would have fixed it, because it was a cracked flywheel which was also a common problem. (They took it apart and never fixed it....it's been sitting in a shop forgotten about for the last 2 or 3 years....I might try to fix it if I can find the rest of the engine laying around somewhere)

[@whitetailization]

You Rock Brother, thanks so much for sharing this information, I am about to have to tear mine down and check this from the things I have read on the net. And thanks for the warning about pulling the flywheel because I would have been one of the ones who tried just that. Thanks again and God Bless you friend.

[@marcdesgagne6636]

We are looking at a 2005 Arctic cat 400. Just finished the carb clean and tried to start it up. (It's in for a starting issue) Will only start up after spinning the engine over with wide open throttle. As soon as you let it go to idle it shuts down. Put a spark tester on it it noticed that the spark is shutting off at idle only. Suspected ignition issue and took a look at youtube to see what we could find. Sounds like we have the problem you pointed out in your vid. The cover is coming off and we will let you know what we find. Thanks Marc @ MD Small Engines , Ontario , Canada

[@LincolnSP150]

Excellent video, very informative.

[@mikehelmsing501]

I think you might have just saved the day. Thanks for the video.

[@kennystiff6308]

[@joewellcome8320]

great explanation of process to trouble shoot and repair.JW

[@WPVMachining]

Appreciate the information.....have to work on one tomorrow that won't start.

[@bitto65]

Forums are great bro, used 'em many a time to source answers. I have actually come across this problem a couple a times before, luckily we were able to locate info for correct placement of the magnets and we cleaned the glue off them and re-glued them with lock-bond. Hey presto, $5 repair instead of $200 replacement cost. That were 20 odd year ago n the motor still runs to this day, after a rebuild bout 10 yr or so back. Cheers n regards to y'all my friend Lee

[@martycope315]

Great job!!

[@13yearsaprepperr.jtilbury.51]

Great video, well done and thank you 👏🏼

[@miketursky1410]

I’ll have to check this out!

[@robertbohling4024]

Thanks for the great advice I have a 400 that will start up and then just die. Worked if I had the switch all the way on with lights on also for a while, then just quit all together. Let it sit for a few months and now it starts and runs in both positions on ignition switch🤔🤔. Ordered new ignition switch will put it in if it quits again and I'll check fly wheel magnets also.

[@donnagant7659]

Very good info. May of just found out what I wrong with AC.

[@ruralsnipeusn1012]

Thanks Jeff!

[@skulledmonte84]

I like how you said "it's pretty easy to get that cover off" LOL after a half hour i got mine off an 3 washer came off too an not sure were they go on at, but i'll figure it out an my magnets look good an are not loose FOR NOW i don't have 250.00 to spend on a damn flywheel Thanks for the vid though

[@heaththompson7809]

Thanks man, I have one doing the same thing..I will let you know if that’s the problem after teardown

[@FordMustangGTRocks]

this happened to my 2012 arctic cat 700 except it first only affected the charging circuit. next time i used it the engine was burning a little oil and it progressively got worse, but never so bad it wouldnt keep oil so we didnt fool with it. i kept driving it for a couple of years at the hunting lease until it finally just all together stopped working on me one day. this made me start a full rebuild of the atv starting with the stator and flywheel. metal got all throughout the engine and stopped up the oil pressure regulator so it was running high on oil pressure. i did a complete engine rebuild, new seals, rings, stator, flywheel etc. now im chasing down rust on the frame and oil leaks on the differentials and i will be putting the engine back in the frame next week. i never would have expected this problem on the 700 but i guess it can happen. im the first i know of. found a lot of other small issues along the way. one major issue was the factory engine mount failed and caused the bolt to nearly wear through the case. its sad that a 2012 has so many issues mean while i have a 1995 kawasaki bayou 400 that still runs great. same maintenance on both and they were used and stored together

[@fromtheright]

Thank for the information. I think that is what is going on with our machine.

[@donniehenson6846]

Thank You Very Much!!!

[@susanbranch8794]

very informative... thanks

[@samcox0102]

Great info!!!!!

[@richardodeneal6104]

Thanks very helpful

[@FurryWereWolf93]

Tracking down a similar problem on my 2004 Honda Sportrax 250ex. Starts, runs for a few seconds, dies, and won't restart for awhile (between 24hrs to about a month). It's on its second stator since I've had it, and it did not fix the problem. Replaced all the electrical when I did the first stator replacement, worked for about a year, now the problem's back. Considering changing the flywheel this time, see if that fixes it.

[@SteveRobReviews]

good stuff. I have a 2006 5 speed, will be watching for any problems, Thanks.

[@bobbyplucar6770]

Great Video thank you

[@DRaysShop]

You forgot the bailin' wire.....lol! Thanks man!

[@johnpeters3946]

I would just like to say thanks much for your vidio saved me much time great deal

[@matthewmilam286]

Yeah mine was a 05 Eiger You were talking about Damaging the crankshaft with a puller What I did was stack washers from the bigger part of the shaft and left the flywheel retaining nut On but screwed out a little ways that way the puller was resting And putting all the pressure on the big nut not the end shaft it worked perfect didn’t break anything

[@NLINE7]

Oh man I was hoping Suzuki fixed this problem by 05 because that is the year model Eiger I have.
