Top tip when you dismantle gears, put a tywrap on as soon as you dismantle them and they'll stay in the correct order.

Nice, been waiting for an update. Friday night with a 🍺 tops it off.

[@motojumble9385]

So satisfying. Great find. Nice to see someone who actually gets into the nuts and bolts of why somethng didn't work rather than just randomly swapping parts. Look forward ot the next one !

[@SuperbikeSurgeryTV]

Thanks for your comment and positively 😁👍

[@cabbage681]

The torque wrench police have been informed, Chief Inspector Tool and Sargent Spanner are on the way.🤣 Great fix and really interesting learning more about ohms, resistance and wave forms, I had no idea how that sensor worked before watching both vids 👍

At 18:46 they nearly got him. He dodged them this time…

Did anybody notice the starter clutch was not timed up before Jim took it off? I'll stop waffle. Great video.👍

I think there's a mark on the clutch and a mark on the shaft 😉

I like what you're doing. A couple of uploads ago, you apologised for swearing, thanks to an individual who likes to watch your videos with his kids. I'm from Belgium. We invented swearing, kind of. So, hey!, see if I care. Thanks for your sometimes hectic shenanigans and getting things right all of the time, in time. Proud ex-owner of a Honda CB750K7 (frame number 000002), Honda 750F1 (last series before aluminium wheels were introduced), Suzuki GT750, Suzuki GT380, Yamaha V-Max (with a 140HP kit. Thanks to Germany heavy bikes were limited to 100HP, which made Japanese manufacturers avoid the European market, or, with V-Max, make a lower HP. The guy I bought the bike from was ((and still is)) an American who bought the bike in Germany but swapped the engine for the USA version), a Moto-Guzzi 850 California, Kawasaki 1300 and a Benelli Sei. Currently, at 63 years of age, riding a benevolant Honda GoldWing 2022 DCT. Had it's top-speed uncapped in the garage and it goes a mild 210km/h at around 6800rpm. Cheerio lad. Greetings from Belgium.

[@SuperbikeSurgeryTV]

That's quite a collection 😍 😁 thanks for watching 👍

[@JimmyRJump]

@@SuperbikeSurgeryTV Well, It's not a collection I gathered recently, but cycles I've had between 1979 and 2022. I'm from '61 and in those days, motorcross was big in mainland Europe and a mechanic in my village was Joel Robert's (250cc world champion) go-to and that mechanic, who was a motor-cros fanatic himself, carved-out a circuit in the woods behind our village. As kids, we took advantage, first with bycicles, later with self-assembled mopeds (Flandria, Zundapp, Kreidler, Puch) and we went faster than the mechanic. I'm gonna spare you of the rest, because you'll have to read about that in my memoires. Just kidding. Cheerio hombre.

Thanks for part 2 Jim! My 96 GSXR750 runs a little rough and then is extremely hard to start when hot. After seeing these videos i've just ordered the new signal generator and all the gaskets, so i'm sure it'll be running like new in no time. Your videos are entertaining and very informative, it's interesting to hear you thinking out loud while problem solving, gives us viewers more to think about while we try and fix out own bikes.

[@Rose.Of.Hizaki]

What some retailers do is mis-report their stock levels. Just so they can get your business. They Report that they have 10+ in stock but they actually dont so its a juggling act for them to order some from some where then send it out to you in respectable time frame. I worked in IT and there were one or two retailers we used to work with that did this a hell of a lot. The annoying thing is they wont send you a follow up email or call you to explain that they dont have it and give you an ETA. You have to go chase them for answers when your order doesnt arrive after a few days or marked as dispatched.

[@paulawright6868]

Lovely work, keep waffling.

If I've not got a manual and don't know how it goes back together after dropping parts. I go to say Fowlers parts diagrams and look at them. Has got me out a hole once or twice. Good work 👍

Nice diagnostic vid 👍been a tech 20+ years but it’s nice to see another tech’s approach to diagnosing an issue especially when it’s not the easiest fault to diagnose. I need an oscilloscope in my life & it’s the next big expense I’m going to invest in

It's always good to see you think your way down into the innards of a bike and come up with the solution. You sure do hold a lot of info in your head.

I wish you weren't at the other end of the country! I've got a 2005 GSX-R750 Anniversary edition that just won't run nicely, misfires at idle and through the range, various loads. - It's had the parts shotgun with coils and plugs and all the TPS/STV adjustments seem correct, bodies balanced... Out of my depth, but struggling to get someone with this level of knowledge on the case!

Early bikes did not have bolt there but the later FI 750 bikes did have that bolt---and I recommend getting some actual JIS screw drivers, easier to work with at times--

[@dandangsxr]

Question Jim, is the arrow on the main case inside the case, a TDC mark as well? So the punch mark on the crankshaft spline lines up with it for TDC? Reason I ask, I've got a K2 600 lump in bits that I want to build so I've got a spare engine for my gixxer (currently at 70k mileage) keep up the work and fantastic videos👍

[@groovedodger]

Its weird how the heat effects the pickup resistance well done finding that I had a similar hot start problem on my car turned out to be crank sensor I found it by firing the parts cannon mind you. only £20 for sensor unlike suzuki a bit pricey.

[@cgmp5764]

I'm not clear why heat should have increased the resistance on the defective pickup, cf the new one. Could it be a lattice defect in the Cu wire somewhere that thermal expansion is changing the wire resistance locally, a microfracture in the wire?

For someone who's got OCD, how could you not torque that bolt up? My wife says that I'm OCD, she's probably right but torquing up such a bolt seems like the right thing to do.

[@steve00alt70]

Oh no the torque police 😂

[@steveclark..]

@@steve00alt70 I raised the point from a genuine aspect, how can you be OCD yet be comfortable with doing that? If that bolt wasn't hidden by a cover, if it was easy to get to, maybe I could understand a bit more. I certainly don't use a torque wrench all the time but on hidden fasteners or critical ones to do with brakes, wheels etc, I sleep better at night.

Any thing you suggest ?

If the UK manufacturers/importers has any sense they should offer you some very fat paychecks to train their mechanics, technicians and engineers.

[@DavidStevenson-gw2eo]

Good idea, but local councils and other bodies are tight as hell when it comes to training monies, I'm thinking of doing something along these lines for those who might be interested, but their red tape is miles and miles long.

[@sharg0]

​@@DavidStevenson-gw2eo I have worked with training machinists and one thing I've seen in various companies are: They need to get their act together and invest in training of their staff! A company that doesn't invest in the ones working for them are doomed to fail because the world isn't stopping around them and people need to advance to even stay proficient because otherwise they will fall into the routine trap, that is do the work without thinking, without seeing problems and not seeing ways to improve. So while I am strongly for tax financed schools and universities I'm also convinced that companies need to set off time and resources to keep their staff at their best. This is a typical topic, schools can only provide basic fault finding - to get skilled at it you need to dive into unknown issues while being guided by an experienced mechanic. In my opinion Jim does an excellent job at explaining what he sees, why he opts for the steps he does and what conclusions can be drawn.
