Asleep? Not at all Absolutely fascinating. Never seen ignition timing in such depth

You’re way too hard on yourself, you deserve a medal for digging down through all the problems.

I want a stop waffling Jim T-shirt with does that make sense on the back! The education is awesome.

Wow. Imagine how screwed you would be if you were just going on the conjecture of the previous mechanic. You'd never think to look at the ECU if they said they'd just replaced it. Very powerful knowledge you have with the being able to use the oscilloscope in this scenario

I know others have said it but for me I find these diagnostic vids you do absolutely fascinating. I get you’re conscious about the length of these but I’d happily sit through an hour or more of these. Brilliant stuff Jimbob 👍🙏

Spend the hour talking about the scope!!! Ill listen! Would love a in depth explanation from start to finish, from how to connect it to diagnosis to interpretation

You make perfect sense Jim ! unravelling this bike's faults has been very interesting 👍🏻🍻

I have a 98 model with the single pick up. I had a similar problem with mine. After chasing back the wiring and checking the sensors and stuff I finally put it down to the igniter box. I got one from DYNA TEC in the states. Sorted the problem and completely changed the power delivery for the better.

This bike might be a PITA but it makes for great viewing watching you troubleshoot

Great channel, I've been watching your back catalogue 👍🏻👍🏻👍🏻👍🏻👍🏻

I fucking love these videos! The oscilloscope is a little over my head (because I've never used one before) but very easy to understand once explained. Keep them up. And no you're not boring me at all explaining the phased rulers, it's all very interesting. You did the same with the bimota and fuel injection events.

Have to say Jim, the way you explain, it always make sense 👍

Friday morning coffee with some Superbike Surgery therapy👍. I find the diagnostic journey intriguing and inspiring.

Excellent video The detail explained on the Pico scope is very interesting. This is why I have been watching your videos for years. Thanks Jim

Love the videos Jim, I worked in a number of bike shops in York for many years, as for saying does that make sense I find myself nodding every time you say it!

Amazing detective work there, very entertaining as well. Keep filming!

FFS mate, that's some diagnosis going on there, brilliant stuff

competant dealership service ceased existing 20 years ago. theyre no longer interested or able to teach anything beyond what was covered in their apprentices training program. "senior" mechanics are no longer interested in sharing knowledge on lazy staff who just want to take that knowledge elsewhere. "knowledge shared is power lost"

I made a big mistake starting to watch this at midnight, you certainly weren’t sending me to sleep quite the opposite, I had to keep watching so I could eventually sleep, when you nearly threatened to finish without showing us the scope I was really worried I was going to have a sleepless week 😂 Absolutely brilliant content and analytical skills. Thank you.

Best motorcycle channel on KZfaq. I've had dealings with Carmo Electronics who have repaired the ecu on that bike. I've had them repair ecu's on outboard engines. Hope you manage to find a replacement.

Jim, your T-shirts should say Not going Down a Rabbit hole. or Stop waffling Jim.

Absolutely amazing fault finding prowess. I'm a lift engineer and often have bloody annoying intermittent faults to find. I take my hat off to your dogged determination. One of the most interesting things I've watched on here. 👍

great info Jim keep it coming

We all want the tee shirt. Jim says "does that make sense"

Awesome job mate!!!

You crack me up Jim. Fat people running past your house 😂 outstanding diagnostic skills though. Always interesting videos mate...

I’ve just stumbled on your video mate I found it very interesting well done buddy

great video, lots of great content.

This was so interesting that I actually really enjoyed it

You're right about the ignition. I had a TT250 that didn't have a key, just a push button to kill the engine. I had just ridden it home and was ripping the clutch out. I turned the basket with the ratchet and it started. Well, that set a cat amongst the chickens. There was stuff flying everywhere. No injuries, lesson learned though.

After watching this I think I'll stick to me trusty old CG125 😅

on the bad one there is quite a bit of oscillation in the dwell time to . top work jim

It was bad enough to see that the previous mechanic had returned the bike with such obvious problems associated with the carburation; but the slack way that the wiring loom plugged into the ECU was just pure lack of care or interest in providing a service for the client. Due to the mechanic's incompetence, the client has been put to great expense and inconvenience. If this was the work of a Yamaha main dealer then I hope the client takes it further to ensure that other clients are not paying for low skill spare parts surgery. I admired your no quit attitude to finding the cause of this problem and your fault finding skills are a treat to watch....and it always makes absolute sense. Keep up the good work Jim.👍

That wire in the end of the crank. I'm pretty sure MT10s use the same. Something to do with oil pressure control.

Just watched the 3rd episode , and the first thing I would look at , the dodgy ECU , is revealed right at the end . When faced with a pile of spaghetti, you can't reverse engineer the flavour of the sauce, you need to get the recipes. In this case , tell us , the subscribers all the funny business first , then myself and others with hundreds years experience in undoing other people's fuc-ups and bodgery. Have an informed platform to spraff on from .

A waffle a day makes your rant go away. 😁👍

Nice one Jim.

A little bit of poo came out🤣🤣 Priceless

I can't put my finger on what is so interesting about your videos, it could be the content, but more likely it's your narration, which is like fiddling with bikes in your garage with your mate when you were young and time didn't matter. So watchable.

I started smiling when I heard you saying ’does that make sense?’. Does that make sense?

physics in school and university v. long ago, but makes perfect sense to me ;-)

Jim,never change,love watching your videos & your narration,always guaranteed a smile watching your content & oh how I laughed at the ‘Pooh’ comment & given I suffer from depression and anxiety I can assure you smiles & laughter are a rarity,does that make sense ? 😂 p.s surely must add that phrase to your t shirt,all the best,keep up the great work & content.

You’re a clever bugger aren’t you!All the best.

Check the output triggering event on ignition coils, on ignition stroke and amplitude , on both banks, and swap coils and retest before replacing the ECU

😎👍😎 What was the coat hanger doing inside of the crank bolt..??

Yes to T shirts!

Proper deerstalker and magnifier stuff. If that makes sense? 😊

It's defo not the wire between the cdi a connector? BTW, am I right that ground side switching implies mosfet?

Couldn't it be a faulty crank position sensor?

How very odd

Yes, that looks normal to me

Yes they should pay, but no way will they! Nice bit of Saturday breakfast waffle. Cant wait for the 4th installment and hearing that sweet satisfaction at getting to the bottom of a stinker of a fault (caused by a bunch of incompetent muppets). Does tgar make sense?!!

Where is the original ECU from the dealer, has that been proven to be faulty.

Every issue is a learning issue. Trial and error wins in the end... your not failing, your eliminating other errors and issues...

Find top dead center then check the valves!?

Name and shame the so called dealer who charged £1000 and fucked it up.

gone down that rabbit hole..does that make sence

Well, at least you don't say, obviously, which can be miserable to here after the second time !

Just started watching your great content, clearly dealer fucks things up than they have to be 😂, ecu change your cover, bollocks, I don't understand, but I understand that

interesting

Own a 1997 vmax 1200 full power with only 9.000 miles been dry stored ,had carbs full rebuild, new fuel lines ,tank cleaned ran rough at low rpm firing on 3 poping on to 4 on test ride and opened up ran on 4 perfect then backfiring ,bit the bullet and sent it to bike shop came back worse 2nd bike shop still the same spent £1000 now and got to the point were i hate the bike, it runs 100% the same as your vmax firing on front on off on rear only difference with my vmax is its had (dont know what there called) the coils disconecred and coils fitted on ht lead if you know what i mean, on your vmax your going for timing being out ? ( waiting for next vid ) could my timing be out even that i know the millage is right and engine has never been worked on from new, this is my 2nd vmax 1st one was rough but ran great spent along time looking for a clean low miles vmax and it cost me alot been 2 years now due to just getting total pissed off with it not running right if its the timing great (wait to see how you get on ) if not its getting stolen and set on fire never had a bike to give me so much pain as this vmax,

I would never have paid for the original work that never fixed what it was left in for... never in all my life have I paid for a service I did not get.. if they don't fix, they don't get paid. As for proving they caused the issue. In the legal responsibility regardless of what you think, you will never prove it in court. All they have todo is deny all responsibility and show your videos of you tinkering with bike in a court. The law is not fair or just.

Enjoying this video series - but I am confused that it is ligning up on the advanced mark at idle. Surely it should be retarded at idle. I ride old brit iron with manual advanced/ retired ign timing so maybe I am missing something.

Two things...1. Tee shirt range pls (...stop waffling...down a rabbit hole...uhhmm...etc etc) 2.Ask the Vmax owner to comment with a postcode of the stealer to stop other unfortunates getting shafted. We already know there is a stealer in the "KINGDOM" of Ipswich curtesty of Freddie Dobbs and The Wurks KZfaq channels

Is that ok 😂😂

Oh Jim oh Jim oh Jim u remind me very much of myself so bloody tormented and everydays a fkn battle that’s ok mate I’ve spent many a day in his majesty’s pleasure Prob have a rather large shareholding in several anti phycotic pharmaceutical companies. ..... but alas yesterday was only slightly less shit than today ! Carry on ol chap stiff upper lip and all that 👍👍🍻🍻🍻

Thank Christ you did not talk for an hour on the oscilloscope . I am off to the asylum. Anyway good you identified the issue. Mick

Instead of "does that make sense" perhaps one could go with "are you with me" a little more inclusive instead of appearing to question the viewers IQ, does that make sense... ? ahhhh

Your easily worth £100 per hour

“A little bit of 💩came out’ 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂 Abdolutely brilliant video 👍🏻🔧

Fantastique
