Those green coils are aftermarket ones. Probably why they both read same resistance, but higher than what the manual manual says, They probably were working fine.  The pickup coils were the culprit, especially as they were reading almost open circuit instead of a few hundred ohms. I've owned a GPZ900R for 34 years (basically the same bike as this one) and done a lot of work on it. Nice to see some trouble shooting being done.

@crebbsjd

The most important thing I learned from you is that Craig, as a mechanic, it is always best to install good factory parts. You followed the tech manual, and the culprit was faulty fake parts. Thank you for sticking with it and realizing that real genuine parts are what's  recommended. Good video, Bearded mechanic and TY again for teaching us the right way.

@chriscollins5488

It's so nice to see a real mechanic at work not just a glorified parts changer.  So many shops now don't do any diagnostic procedures to find the real issues.   Great work Craig!

Many years ago I picked up a 1990 ZX-10 off craigs list. I did not have a chance to put too many miles on it but along with a carb problem it also, I eventually found out through trial and error, had the same type of coil problem. The owner had given up on it and he also had a garage full of toys to play with so it was just up against a wall covered in dust. I got the bike for a song and a dance.The bike had not ran for over 10 years and wasn't running worth a crap when the previous owner stopped riding it and gave up on it. Not doing a commercial here but for anyone out there having this problem you can get a set of new Dyna brand high energy coils and swap those out from the factory coils. Once I installed the Dyna coils in I was able to finish syncing the carbs. Gave her a bath and oh my god that bike was awsome and with only a little over 15000 miles on the clock it looked brand new and ran like new. Didn't have it very long before a collector of these types of bikes bought it from me somewhere down in Alabama. Kinda makes me wonder if this coil thing is a common problem with these bikes!!😁

@tylerpellegrini2984

Your a shining example of a dedicated and excited mechanic. You rock Craig, and Dan your an awesome cameraman love how your involved in the videos too

@curm1778

moral of the story? check for continuity and resistance even with new parts. saves a lot of diagnosis & installation frustration. strong work!

@steveh4564

I owned that bike, bought it new in 1986 in NY. Still to this day the best all around motorcycle I ever had. Great to hear it again. Ps.. The Ninja 900 was the Tom Cruise Top Gun bike, not the 1000R you're working on.

@lothre

Fantastic job done by Craig, when nobody else would touch it. No greater gut punch than making a bikes issue worse when 'fixing it', but Craig stuck with it and pulled it off! Well done Craig and Dan!

@yayagazab4449

The fairings alone drive mechanics insane. Moto mechanics fear that the amount of time put into fixing the problem will prohibitively increase the repair price so much that the customer will not pay because they won’t believe how much effort went into resolving the issue, so it becomes a cost benefit analysis decision. Glad you showed how difficult diagnosing and repairing a problem on an older bike can be.

@spondal1

Watching these videos reminds me of my dad’s motorcycle shop growing up. Him and one employee, took in every type of bike and brand, never had a diagnostic tool just could listen and shakedown and know what to fix.

@T8J2124

Long time bike n beards / srkcycles watcher here, i love this channel, as a mechanic theres so much channels out there, but they are all either too simple and trying to be cool, or they are way too long and unenjoyable to watch, Craig is just an amazing presenter with tons of knowledge and you manage to cut it into an interesting episode!! Please keep going Craig and co! Greetings from Europe!

@FirstLast-dj4ho

Craig you may benefit from an IV holder for your hanging fuel tank.  Wheel it around where you need it and adjust for height.

@cory0898

Amazing how intelligent Craig is and how much dedication he has for motorcycles. Love watching him work and listen to the amount of information he has.

@BrianKnect

As a former service manager for a Honda motorcycle dealership, 89' till 93'  I must say I commend you on how you took care of this customers Ninja.  Much respect to you.

@parker1ray

I had one do exactly the same thing. It was a coil that would break down once hot! I am 62 and do miss working on machines. I drag raced Mopar's and Bikes all of my life! I lost two brothers to motorcycle accidents and promised my mother that I would never buy another bike. I kept the promise for 20 years and eventually had to ride again. I had a very good friend who passed away last November. He was once of the best bike mechanics that I ever knew. He ate and slept motorcycle! Rest in peace Rodney Allen Jett!

@JacksTheRabbitsTube

Nothing more satisfying putting on your gear to test all your hard work. Recently got my cylinders honed, installed new piston rings, and lapped the valves on my 130k mile Ninja 500. Test ride went good so I took it to VIR and ripped it around the track. Doesn't get better than that.

@MolltoMotto

I really appreciate the fact that you let us know how many time this repair took, people use to think that their vehicles can just get in the shop and 30 minutes later it's ready to

@kellydrover1994

It’s nice to see someone take the time to make old classics work again!

@motohio5923

What you said about other shops just not wanting to do it, that right there is the difference. They're in it for the quick fix and the money. You highlighted how passionate you are about what you do. Love that!

@Importman2009

Nice to see someone actually spending the time to diagnose the problem and use old-school methods without hooking up to all sorts of computers.
