Am I the only one who appreciates the fact that Jim still puts out a video showing that he fucked up ?! We all make mistakes, it’s part of the job. Live and learn Jim , live and learn.

[@chris9650]

Mistakes are experience. How we learn.

[@harryw9598]

was gonna say almost the same.

[@colinpierce2585]

I think most wouldn’t have put that video out…fair play Jim

[@keithf8890]

How many of us have been there?Its so easyto let a mistake take you down that rabbit hole.All the best.

[@00Munki]

Yeap, fair play Jim

[@eastcoast5004]

respect mate not many bike techs would own up to making a mistake in my opinion your the best tech on youtube and should have way more subscribers all the best mucker

[@kevinwilliams4899]

I don't think you waffle too much it shows your thought process and how you approach these things. And from my years in the power industry just because you have explained something it does'nt mean someone else has understood it, but you make sure your viewers do. Also a big up for admiting your mistake insead of editing out. And as you say that is how easy it is to led astray fault finding. Keep up the good work love your content.

[@andyjdaviestjk]

Well we are all human and it was still interesting to listen and learn, I try and do my own work on my varadero 1000 and these videos are great for learning how to do things, 👍

[@flangmasterj]

One man's "waffle" is another man's enjoyment. This is all good stuff Jim.

[@teamgas]

Appreciate you putting up your mess up videos. We all make them , few have the integrity to show them to everyone!

[@stevenrowley9481]

😅I thought the same initially with the pressure. I worked on these bikes when they first came out but never had any problems, however, I also worked in Ducati's up to 2016 and some have very similar set up. Had the same sort of problem which turned out to be engine temp sensor. Some Dukes had 2 sensors. One to feed the ECU, one to feed the temp. gauge. If the ECU sensor was reading incorrectly then the ECU thought the engine was hot, so wouldn't richen the mixture on cold starting.

[@DannyM9348]

Excellend video Jim, these uploads are turning into the highlight of my Fridays! To give credit to yourself, with where you started you were on the right train of thought. Props for highlighting your errors. It's easy to let pride get in the way and not admit to it. I believe that anyone who is willing to admit an error and learn from it are the best in their respective field.

[@brianmcclintock1194]

i love jims openess and honsety when he drops the ball massive respect in thes days of perfect build youtubers we have !!

[@speedyboolooks]

“My heads gone”. Know that feeling all too well well 😂

[@Subjectno23]

Brilliant video, love your logic and the fact you admitted a mistake, an honest youtuber is a rare breed. We all learned from your mistake, thanks! Also, I love the "waffle" so much extra info there, much appreciated.

[@kevinsmith-dn1px]

So refreshing to see Videos where the person actually knows what they're doing! And gives thorough explanations too! Nice work 👏

[@paultugwell9855]

You are a fantastic technician and a great teacher keep doing what you are doing, I have taught thousands of automotive apprentices over 30years and you are good

[@gtimike]

FAIL? = First attempt in learning . As said we all make mistakes . It's how you learn from them that matters. Stumbled across this channel a short while ago and have learnt a lot especially the scope use(pico). My background isn't bikes but cars and vans and there's a lot that crosses over into those - i do have an interest in bikes including owning a Vespa LX125. The thought processes you use are also very insightful Jim and well thought out even though you might think it's waffle

[@MarkJYule]

It's called being human 😊 Your diagnostic process is what matters 🤷‍♂️ And yours is superb 👍

[@sthildas4857]

We are all learning, reversing out of that rabbit hole, glad you told us. Great bike, thx for sharing.🏍

[@joaoxufre9296]

Yes I remember the split fuel filter on the KTM

[@ianlee487]

Jim we all make mistakes your human. Let me say another great video your amazing mate.

[@tommybjork2674]

I like your videos, because you always show the whole story, including mistakes. Looking forward to seeing the vmax run as well 😊

[@user-pc2dz3bd3u]

You know its a real world video because this sort of thing happens - thanks for sharing

[@camperp195]

Stunning,cracking piece of kit!

[@thetonetosser]

Fantastic bike just standing still.

[@sirpatrickbikes]

If it was me I'd probably change the fuel pump and filter anyway as they are old and not that expensive. BTW that RC45 sounds bloody fantastic!

[@motorcyclegarage2307]

ST2 filter would fit. Similar pressure. Thanks for the testing detail. Very helpful Jim.

[@benrichards5160]

Let yourself waffle Jim!! Adds another layer to the video, instead of just the bike and whats wrong with it we also see your thought process and your wealth of knowledge!

[@andyjrichie6709]

Quite funny Jim, easy enough to make mistakes for a professional, super great video,

[@TheMostDangerousWayPossible]

great video Jim!

[@jonahlloyd3149]

Well I learnt a lot about my RC46 fueling system which is identical I would think, so thank you very much 8-)

[@JimBiddle.]

It's reassuring that even someone as experienced as you, can catch yourself out.

[@ragnarironspear1791]

I helped hang one of those from the ceiling in Joey's Bar years ago

[@Steve-wx9gl]

Good honest video love the humour thanks JIM

[@rogerthedodger5788]

@ 15:30 .... me being in my 60's you sound like my Doctor delivering his diagnosis 😂

[@marcusFZ6]

Shit happens but you've told us the small faux pau, so all good. Nice that you've scored a win with the "Lean" start and given it a little sniff of "Start ya Bastard" (look it up if you've not heard of it) Side question - when are we getting the winning video of the V-Max starting like a dream? Keep up the good work

[@stuwhite1969]

Awesome bike!! that air box lid is a crime

[@garymorgan628]

If you learn from a mistake then its just a valuable lesson learnt 👍

[@IN_ZANE_]

Still an interesting video, learned something new

[@Animo92]

Had a vfr800 vtec that the fuel filter had disintegrated, didn't help that the tank had 2l of water/rust mix in it though. Ended up picking up a full aftermarket pump and filter combo for £115

[@99gpandy28]

Motion pro injector cleaner tool ,or improvise and ultrasonic clean them ,they prob can't flow test em as most injector cleaner shops only cater for car injectors, but some will ultrasonic clean them anyway but you won't know if they bleed afterwards 👍

[@garysergeant9086]

Love your videos I do the same thing when working on bikes including swearing

[@pbysome]

Still sound logic, a man that never made a mistake never made anything.

[@johnwalker194]

A faulty coolant temp sender affecting cold start ? High reading might not throw a fault and illuminate the Fi light ??

[@spatchist]

A V4 that isn't a V-Max , makes a change.

[@2ane]

im rather perplexed that someone took a bike as rare and expensive as this and turned it into his track-tool. I mean this is probably one of the rarest japanese production Superbikes ever?

[@smd-tech]

Maybe because thats what it was built for, not to be locked away being a fucking ornament ?

[@markaddy53]

shit happens lad all been there keep at it ul get there great video as always next one please

[@Phil-pw7ko]

always with Honda's pop off vent line at regulator, wet vacuum hose port is bad, VTX 1800, VFR 800, quite common and diagnostic is quickly known so can be eliminated or discovered in mere minutes,

[@martyndunn1905]

Stop waffling jim 😂😂😂😂

[@munter10]

Bikes like this should just be kept in a glass cage in a museum.

[@user-lk8lq1vx4t]

Nah, Hondas are made to ride.

[@nialbarnsley4108]

What a wierd thing to say strange,

[@pauln6803]

I was on a trackday at Donington park when someone stacked a Desmosedici RR. But fair play to the Duc owner for wanting to exploit what it offered, even if it didn't end well.

[@dalelyons4366]

I’ve found you on a worm hole … thank god ..

[@maxheadvroom1923]

has anyone mentioned the cold start on the TB's yet,

[@TringmotionCoUk]

Did I hear MAF sensor? These often fail to lean fuel giving rough cold running and bad starts. Just fixed a Subaru with this issue

[@richardjohnson3370]

No maf sensor, it uses 2 map sensors

[@DoRC]

I was wondering how it could run fine after starting with no fuel flow..

[@zweispurmopped]

Sometimes red herrings just get you. It is what it is. 🤗

[@ferguscawley11]

Temperature sensor reading? Poor cold start but fine when warm ( lean condition) ?

[@SuperbikeSurgeryTV]

You are ahead of me 😂

[@mrflores7708]

How do you calculate the labour costs for the client when there is all this YT filming being done at the same time?

[@SuperbikeSurgeryTV]

It's farley easy to estimate the actual time the job would take without all the messing around with a camera. I then charge 75% of that number. Keeps it more the fair from the customers point of view.

[@charlesscottkelly]

Keep the waffle we enjoy it

[@stevekirk6399]

where part 6 of the yamaha?

[@575ban]

That's a serious case of CBA on the bikes behalf 😂

[@575ban]

Can't Be Arsed to start 😁

[@fw1421]

I can’t believe Honda doesn’t have fuel filters available for this bike anymore.

[@j2tmfc]

Eprom been flashed by any chance?

[@pauln6803]

These were the days of race specific chipsets and power commanders.

[@buncobooth]

I'm only 2 minutes in and I'm shouting "COMPRESSION TEST" at the screen 😧

[@SuperbikeSurgeryTV]

😂

[@eugenecussen3735]

ha ha ya sound like Mark Heap 🤣

[@clivecarrington8814]

Great content. Could you be a fellow Welshman?.

[@llewvirtue861]

That fuel filter is still U/s

[@wotnoturbo]

You some kind of chancer, what game on?? 🤣🤣

[@oodiddy9778]

only 250 of these ever made.

[@munter10]

What a POS! It was once a great bike for it’s time.. and could still be a great machine IF it was kept up to date with maintenance etc. It’s probably been in storage for years and has a clogged fuel system with blocked injectors and blocked fuel filter. Good luck Jim, and that wasted time on chasing fuel pressure gremlins, don’t worry mate, even the best mechanics fall into traps like that 😂

[@peternicolajsen4161]

Vfr not rvf.😂
