Jim, don't worry about the 'Waffleage' it's entirely interesting and, with regard to the length of the videos, also don't worry. I'd say that most of your subscribers would be glued to the screen for hours just to see the outcome of all the seemingly impossible situations that you're presented with. Absolutely riveting content. 👍
Love the wafflage, without it I would never understand quite how complicated bike electronics are. Keep up the good videos. It was definitely easier in the days of distributors and feeler gauges,
Love your videos, I've watched every single one, think your too hard on yourself tho as the waffleage is great. I love how you narrate the videos in so much detail its what makes you stand out. Thanks Jim 😊 👍
Mate.....I really appreciate your positivity. It's really really appreciated. It's a huge amount of work and time to get a video out every week. When I get comments like this it means lot. You are a legend 🙏😁
Ive never heard jim say anything technical that's incorrect and im a stickler on tech details. the guy really does know his stuff, very knowledgeable indeed 😜
Great stuff mate, the waffaling is great, don't worry about the language, the ones who have opinions are just jealous of your knowledge of french😝 Oh, and yes it does make sense and please start printing the t-shirts with some waffalidge that makes sense, maybe🤪 Cheers
Sometimes I feel stupid when I can’t work out what’s wrong with a bike or car. So to hear Jim say, “what the fuck is wrong with this motorbike?!” makes me feel a bit better. 😂
Just discovered this great channel. Alan Milyard is interesting but not a patch in Superbike Surgery. Brilliant, keep waffling as it's all interesting.
Not sure where you are on this one. But, I am fairly sure that this is a temperature sensor fault. I don't know if it has an air temperature sensor or a complete MAF, but the only thing that is not constant is the temperature. It's running lean on cold start, so what controls that? Well for starters the sensors, then the ECU, fuel pressure and lastly injectors. MAF sensors are in my opinion what most often fails. If you don't reply here I'll post it on your Discord to make sure my idea is heard 😊 Cheers (the connectors in between is also a must to check of course)
Is it tomorrow yet? Great videos and lots of info. FYI the waffling is the kind in thought process info that helps us glean insight on how to tackle things. More waffling! I've liked and subscribed. Cheers
Have you tested the coolant and air temp sensors ? ECU is being told engine is warm when it isn't and ain't giving the rich mixture needed for starting
Could also be worth checking oil/air temp sensors if fitted or TPS? quite common on the GSX1400 I found, Also the STPS for cold start can play up. I know it's a different bike but these are some things I have come across.
Where is part 3, or did it beat you. Great video by the way. Does your scope have auto detect and ranging. The scopes I started on 20 years ago had a basic auto detect and ranging function,I’m surprised something more modern doesn’t have it. Anyway very insightful video.
Great wafflage as usual. You might want to add something about the scope use in your titles to help the YT algorithm. Your explanation and real life use and diagnosis will be of help to all motor mechanics not just us weird bike types...does that make sense? tshirts please !
As a motorbike mechanic since 1980 and a qualified fitter and turner working in a shop in 2024 you have not got time , at $140 per hour charge to the customer. The sad reality of 2024.
what are your temperature sensors reading when cold? I've seen where a out of calibration temp sensor, or one that goes "open" at certain temperatures can really mess up your day. the computer is totally dependent on the big 5 sensors (or 4 depending on the vehicle) to calculate for the fuel map to use- air temp, coolant temp, oxygen sensor, throttle position sensor, mass airflow/manifold pressure sensor- and with that, i would (before condemning any sensors) check the reference voltage to the sensors and sensor grounds (and don't just ohm test the grounds- check for voltage on the ground circuit under operating conditions- a wire can ohm good with no load but fail when under a load). bad in is bad out......... . is there a way to see the data list for the computer? engine cold, the intake air and coolant temp should read the same. when cold start, the computer shouldn't be using the oxygen sensor input, but it has programming to input values to keep the engine running. then look at throttle position sensor (you did say it runs good warm, so i doubt that's it), then the ignition input. also you said it runs good warm, so i doubt its a mass airflow/map sensor. one last thing: most Japanese computers are rarely the problem. i've seen in my whole 30+ year career probably less than 10 computers that were truly bad- it can happen, but it's rare.
Jim , you apologise way too much , which makes me think you are a nice person , don't mean to blow smoke, just wanted to say your videos are great and informative.
No. It's fuel injected. It has a fast idle cable that increases the revs only. The bike needs a richer mixture which is achieved via additional fuel commanded by the ecu. Straightforward enough really.
WTF's with the cliffhanger.(joking of course)......Could of at least given it a quick turn over and see if there was any difference. Those little pots are obviously quite sensitive little beasties if they make that small of a difference. I think you've gone the right way by going full rich and see how she goes. The only way to set them up properly is to have a funky graph machine like you have to measure pulse width. The engine must also be picky about the amount of fuel that it likes for start with a fine adjustment. Can't wait to see how it all goes in next weelks video.
Met a pillock on one in a garage in Suffolk he was just so full of shiet , he wanted to race me on my fully de restricted blue printed 1989 ZX 10 , not the result he expected .
Because he's an expert in his field, and we are not, hence why you have no idea what he's talking about. Don't like it, go somewhere else... simple. If he were to cut out the stuff that you don't want to learn to understand etc, then the videos would be either very short, or very scripted to suit layman people.

Really appreciate the positively, thank you 🙏
This is so true mate, 👍
Totally agree
Love the detail in the videos, the troubleshooting and most importantly, the successful outcome.
💯glued to the screen,,,fascinating stuff!!!
100% Couldn't agree more. 👍
Has part 3 been done yet ?
Love the wafflage, without it I would never understand quite how complicated bike electronics are. Keep up the good videos. It was definitely easier in the days of distributors and feeler gauges,
What happened with this bike? You left us hanging 😢

Pleasssseee part 3 ?
Jim, you need to start selling wafflage t-shirts, reckon they'll go down well
You are very clever, man. I would trust you with my motorbike any day I wished I knew half of your knowledge.
Ive never heard jim say anything technical that's incorrect and im a stickler on tech details.

Thanks for taking the time to do these videos Jim - they're brilliant 👍🏻
Scope work is never boring... 🥰
Very good explanation as always👌
The "scope wafflage" was the best bit
I love the videos , really interesting. Keep up the good work

great video lad im totally out ov my depth sure your not ul sort it hopefully next video please
Very interesting. Maybe using a colour tune would be better for getting the individual cylinder adjustments right in this particular case.
Very baffled😂, but very interesting great video
So what was it? Can’t find part 3
Have you tested the coolant and air temp sensors ? ECU is being told engine is warm when it isn't and ain't giving the rich mixture needed for starting
hahahahaha me screaming the same thing and I really feel his pain about the "manual" awful doesn't do it justice !
You are ahead of me, wait for part 3!
recorded in sept 23 so this is all hopfully sorted
@@BRUM9922 How do you know it was Sept 23 ?
@@ferguscawley11 laptop 3:08 in
was there ever a part 3 ??hate it when I start to get into a series and then it leaves you up in the dark !
Bin the power commander ??

Defective intake air temperature sensor messing up the fuelling?
Correct
Did you ever get to the bottom of this one?
You said it had a 'choke' cable to enable cold starting. Is it actually working?

Did you ever fix this one? Just interested in outcome. Thanks
I have some pictures from the workshop manual that may help
What about honda car injectors of the same era? I'm sure my Integra Type R ones are 240cc
Did u get to the bottom of it jim ? .my 5pw R1 similar very poor cold start but when warm 1/2 turn of the crank and fires instantly

Yup

I think the term you are chasing around 13:30 mark is "RECALIBRATE"
Jim , you apologise way too much , which makes me think you are a nice person , don't mean to blow smoke, just wanted to say your videos are great and informative.
Where is your workshop,what part of the country?
Part 3 ????
Cliffhanger 😲
Cold start sensor for choke (electronic choke)?
Did the Spider senses get to the bottom of this one?
Part 3 this Friday!
If it is those screws and it richens the whole map the power commander could be reset on a rolling road.
Doesn't this have a (choke) enrichment cable, and is doing what it's supposed to do?
No. It's fuel injected. It has a fast idle cable that increases the revs only. The bike needs a richer mixture which is achieved via additional fuel commanded by the ecu. Straightforward enough really.

Was that a mug of Bailiey’s you were drinking!
My ex wife was prone to waffleage, but then again she couldn't fix motorcycles
JIM did you fix it mate?
I hate to divulge my age,but i will stay with my carb bikes,these fuel injection system look like more drama than they are worth
Bad power commander. Common. They suck, especially the pciii
No notification 🤬🤬 thanks YT
Jim you tease 😋
The good ole parts cannon
Met a pillock on one in a garage in Suffolk he was just so full of shiet , he wanted to race me on my fully de restricted blue printed 1989 ZX 10 , not the result he expected .
25:42 That's 20% more. Certainly not insignificant.
Cruel ending.....

hahahaha wasnt it

i dont understand why you talk about shit no one understands cut half of that bull shit out and your videos would be amazing
