Ducati ST4 Streetfighter Cafe Build Part 6 - REVISED TIMING BELT INSTALL.

This is a step by step on replacing the timing belts on a 1999 Ducati ST4. This is a revised version of this video. I made some errors in the first one and I felt I needed to correct it so the job can be done the right way!! Apologies to all who commented. Shout outs to "bradthebikeboy" and "Eclidean". Thanks for the CORRECT info.

Love your video, and your small story about your dad. Thanks a lot. I use a small long screwdriver to check the top dead end of the compression stroke and in 6th gear crankshaft rotation is somewhat easier. Greetings from the Netherlands.

[@zachdiaz1927]

Love the video brother and I’m glad the universe brought me to it. I’m planning on buying my fathers 2001 st4 for the sake of keeping it in the family and so I do It with intentions of keeping the lineage on. I stumbles across your videos after doing some research on the bike and I feel as though nothing could be more perfect than to buy my dads bike. I love the story behind your dads toolbox and how it inspired a creativeness into you… god bless you and your family

[@lrowlands53]

Fantastic instructional!!!. I'm blown away by the 110Hz trick. I'm a lifelong muso so this is my language. Love it. You realise of course that 110Hz is 1/4 of A=440Hz, the international standard for musical pitch. Uncanny. Who would have thought?

[@laurencegraham9368]

Got to love the yanks and the way they tinker away on stuff like this.

[@glennpettersson9002]

I have just binged all the Ducati vids and it has been great watching, thank you. Your bikes are great!

[@VDRNW]

Excellent series of vids. Im looking at aquring an ST4 soon, and your dissection of all the major componets of this model is putting me at ease of buying an Italian steed. Thx

[@hectorduncan7449]

Never mind torque wrenches, you know the feel when It's right for whatever material. Good work and nice to see.

[@youtruckrek5121]

Glad to see you back on the bikes, thanks for your time

[@andrewhansen4179]

Good video. It's a great refresher course in doing the 4 valve Ducati timing belts. Even though I've done the process before, I got some tips that will help me in my next belt change. Thanks.

[@chrishard7616]

Thanks for sharing....I'm getting a Monster 821 and like doing all the maintenance myself. This is a great insight to the belt service requirements. Looks relatively straight forward if one is particular and careful. Nice job! Cheers.

[@VMATT500C]

Thanks, for the family story. Good job in the Duc.

[@afonsosn6895]

Thank you for posting. Entertaining and educational as usual!

[@TheZooness]

Man.. I already know how to do this, but not only did I watch the video in the morning, I had to watch the revised one too... good job on the video.

[@valentinlazarev589]

Many thanks for such a great tutorial! It was very helpful for me today. Greetings from Russia!

[@doca8792]

Very Good! Helped me with my newly acquired 996S belts. Thanks.

[@SuperLeddie]

ok glad we cleared that one up, can get a bit confusing but the word clockwise cleared it up. i always try to understand why manufacturers do certain things. btw got onto your channel by your cb750 series which then made me go out and buy a gl 1100 goldwing that hadn't gone for twenty three years and restored it but using gl 1000 fenders with a bit of adaptation to the rear. would have liked a cb750 but my budget wouldn't stretch to it. keep on hackin, love it.

[@raysoucy1637]

Nice story about Dad!

[@IchibanMoto]

congratulations again on the certifications Dino !

[@garya3056]

Nicely done! Re the rear brake squeal... One of my scooters is an 06 ST3 and I have eliminated any and all sound by using a bit of copper grease on the non-caliper side of the pads. Enjoy your new ride...!

[@HypnoticPattern]

I really want to get an ST4 for touring. The bike looks ridiculously complex, but so much fun.

[@TheBear351c]

congrats on the Ichiban and Utube certification. Another well documented vid, cheers Dino.

[@tcrides2137]

Great job on fixing up the st. The neutral thing is a Ducati thing. My ss does it too. I like the retro monster look man, Its cool

[@stevieg7403]

You made the belt change look quite straight forward. I’m looking forward to the value check. Well done!!

[@aukanmeister]

It actually is straight forward. The valves is not very difficult either. Can be done with tools from the 50's :) My KTM LC8 is way more complicated. Ducati's are great! 916 was my first love in bikes.

[@bradk8694]

You finally made it into the upper echelon of bike building with that Ichiban award- congratulations! LOL! Seriously though, I've been following this build and I just want to say thanks for putting in the time and effort to film it all. I'm not planning on doing anything similar but it's been interesting to watch. I will say the one thing I do find VERY useful in this build is how you measured your belts! I've got an 08 Hypermotard 1100s and will be checking my belt tension your way instead of the Allen wrench method. I've never had any luck with the tuner apps but I've never seen it done before, either in person or online so seeing it here gives me direction on the proper way of checking the tension instead of guessing. I'm not convinced it makes a huge difference in longevity but I might as well do it right and this will help me tremendously! Finally, the bike itself looks fantastic- you did a great job! I'm not sure if you're done with this bike or if there's more, but I'll be looking forward to your next video of whatever you tackle.

[@DeanSegovis]

Thank you! On the belt tension, be sure that the cylinder you're adjusting is at Top Dead Center!! I actually made a slight error on the vertical cylinder and didn't rotate it far enough. (I went back in and corrected this the other day and installed new Fuji style lock nuts) You can remove the spark plug and insert a long skinny screwdriver or a wood dowel down in the cylinder and watch it as it rises up to TDC with the piston. Get it as close to TDC as you can while turning the rear tire with the transmission in first gear. If you go past a little it's OK but it's important that you don't turn the engine backwards to line it up. The belt has to be loaded in the forward direction. That way, the side with the adjuster is NOT the side that's loaded up with extra tension. Good luck!

[@HockeyVictory66]

Very nice bike. You did an awesome job.

[@christianvlek]

Love the overflow bottle !

[@samselectronic4548]

Great job on both video's😎

[@mikescuba1]

Good job, very useful. I'm thinking of getting a Ducati ST3 so I wanted to get so idea as to how difficult it is to change the cam belts.

[@frase1234]

Good Shit - G'Day from Melbourne Australia

[@fievebr]

Love your video. Thanks to your dad.

[@toadroller]

22:00 plucking with a guitar tuner for the win! Also, I inherited my father in laws tools and I have a "mystery" drawer. When I come across a job I don't have the right tool for, I go rummaging around and usually come out with something, muttering "so that's what this is for" to myself.

[@62falconizer]

Thanks for this brotha! You rock

[@kurtivan4869]

Thank you for the great video.

[@oliverglen4208]

easily the best cam belt change video I've seen for the Ducati. Way better than the rambling from DucatiTech...

[@andrewhansen4179]

Totally agree!

[@cordcd7]

I have the same bar end mirrors on my Nighthawk. For the price, they've been great.

[@jimmypinch]

Cool bike, love the olive oil can

[@masterblaster6434]

Magic idea to use the guitar app at 110 hertz to adjust the belts. Thanks heaps.

[@gman3725]

Awesome video

[@thoreabbath9366]

Thank you for your video

[@brianaustin1328]

Cool Dad story!

[@cigarobsession]

So have you run it now that you did it right and if so did you feel any difference from the first vid?

[@duncanwood5275]

Great sequence of videos, but i think i must have missed the part where you relocated the coils. I have a similar project underway with and ST2 donor bike and the coils are proving to be a major headache, any advice would be much appreciated...

[@schwenny100]

hello, thanks for the great video. the top with the wrench is great and the function with the app is just great, but a question which app is it used?

[@ksfixitmangaming617]

This is what we expect from you. Do it right or not at all. thanks Deno

[@ComputerGeekOnTwoWheels]

Ducati does not recommend the use of locktite on the belt tensioner bolt. You just need to replace the bolt every other time.

[@BlueBeemerBoy77]

Great video! Im putting together my MS4. THe 1-pin connector at 1:08 in the video, whats that for? I cant seem to find the connector it goes in to...

[@erikeggenbakstad]

About finding the correct belt torque, if you will. Should you not set each cylinder at TDC for each check for correct belt tightness? If not, it will give different values because one cylinder will have valves and valve cams under pressure going out to the belt. Just a thought though. ..

[@DeanSegovis]

You are absolutely right. After uploading I was informed that I failed to rotate the vertical cylinder far enough to be at TDC. I should have rotated another 90 degrees.

[@droneforfun5384]

Dean Segovis At 24:25 you are turning the crankshaft 90 degree counter clockwise to your red mark. Could you try to explain what is wrong? Should you have turned the crankshaft 180 degrees counter-clockwise?

[@grantsnell6782]

Just counting the teeth on the crankshaft and the camshaft sprockets, and they are the same. Dont know if you've previously covered this, but assuming that is because of the desmo?

[@groenhart58]

thanks for the video. Please give the link for the hertz app. for google as well the Apple app store

[@sailorcto]

Any thoughts on Evan waterless coolant conversion for motorbikes?

[@elisevilleneuve5416]

Hi, I'm trying to replace the timing belts on my S4RS but I'm unable to take off the vertical belt covet. Do I need to remove the tank. Thank you

[@VLDuckyy]

Hey, after I change the belts and start up the bike and the vertical cylinder is misfiring, any idea where I messed up?

[@zeprolet]

Hello. What program do you use on your phone? link please?

[@garyx5x]

Isn't Blue Point like Snap On? Nice wrench.

[@Mad-Duk_Machine_Werkes]

LOVE IT! LOL - those belts youre "Replacing"??? look oddly like brand new belts that were just put on a cpl days ago ??? LOLOLOL Youre the best Dino! Hahahaha

[@Mad-Duk_Machine_Werkes]

ALSO, you can try and bleed and flush all fresh fluid in that hyd clutch and possibly make neutral easier to find, someone has already upgraded your clutch slave and the clutch Master rebuild kit is only $25 if you think it needs it...

[@Mad-Duk_Machine_Werkes]

Brad- (by the way) might be the smartest Ducati Tuner and mechanic in the world, pretty much everything he says should be taken as FACT, I'd trust his advise over the factory manual........ his website is EXCELLENT

[@ernestburden5614]

Thanks for the video. I'm into my first belt change on a Ducati 749 and am looking for all the help I can get. A comment and question. When you remove the vertical belt (@ 12:55) you do not mark this belt with paint, and then when you replace it (@ 14:37) you refer to the horizontal belt and then show a vertical belt with marks you mention you copied. I am assuming you copied these from the horizontal belt you marked and are assuming both belts are the same. Are they? My research so far with my Testastretta engine says to mark both belts separately as they are not the same. (Just in case anyone else is trying to apply your video to a slightly different bike.) Thanks again for the video.

[@highfive1359]

Sorry to ask a question on such an old video but what size socket is that homemade spanner made out of? I'm doing research before I get into this same job

[@Rydrdg]

Hi do you have the exact name of app to download?

[@_S.E.J_]

Time to buy another cb750 I miss all those videos :(

[@user-qy4tc9bl2r]

Как ещё можно проверить натяжку ремней? Спасибо!!!!

[@Mad-Duk_Machine_Werkes]

LOL - still watching the updated video - (Im sorry, you just cant win can you Dean? LOL) the cam drive gear turns at HALF crank speed, so your original mark you made at "180*" was 90 degrees on the crank.......... (cams operate at HALF engine speed, every TWO crank revolution is ONE in those cam sprockets.......) BEST way to tell if youre TDC on back cyl is a LONG thin screwdriver or dowel or smooth rod in the spark plug hole

[@DeanSegovis]

KZbin won't let me do annotations anymore which sucks ass! Fek it. :) Close enough!! TIME TO JUST RIDE THE BITCH!! :)

[@user-qy4tc9bl2r]

Что за программа замера децибел?

[@mikemaifeld6280]

What happened to that Ichiban Moto guy did he retire?

[@michaelyiannett4515]

Wheres the old intro with the cool animation!

[@ever-sd9iz]

😁,looks like keth code😃

[@Jeremy6981]

Don't know if I could ever get used to the sound of a dry clutch.

[@truantray]

Jeremy Newman Yeah...I owned a Dookie and never liked the rattling, or everything else that constantly broke on it.

[@andrewhansen4179]

There is a modification you can do to the dry clutches that reduces the amount of clutch rattle. Just check the internet for the recommended mod. I think it's called the Ducati "quiet clutch mod" and it's almost as simple as pulling the clutch plates and adding one additional plate. I did this mod to my ST4 and it really helps, without totally eliminating the sweet music of a dry clutch. I like a dry clutch vs. a wet one where all the clutch debris is entering the oil. Just my 2 cents.

[@SuperLeddie]

is one side pinned and the other not because of direction of rotation.

[@HackaweekTV]

No. Same rotation.

[@SuperLeddie]

so if the rotation is the same, it means one side is trying to screw itself in and the other side is trying to screw itself out. hence the pin on one side only.

[@HackaweekTV]

No. They both are turning clockwise, thus tightening.

[@flamejasstyss3749]

please take a st4s.

[@arrowinquire]

A higher gear makes rotating the engine easier =:-)

[@fnbdraco]

Need a new hack video

quand on roule une ducati savoir prendre soins d'elle c'est aller loin et longtemps

[@Ali848evo]

Help me

[@curlymyhero]

I have an ST2 with just 9000 miles. Belts r recommended at 10K but with your guitar tuner trick at 12Hz y not just "tune" my original belts? The valves just c tightness, not "newness"...

[@andrewhansen4179]

Belts are relatively cheap and the process easy enough. Just take your time and be thorough. The belt change process for the 2 valve motor is easier than the 4 valve motors. An overused belt is a troublesome condition. The belt could break and mess up your motor. I've run my belts up to 12k miles without incident but that is max for me.

[@arlingtonhynes]

Tuning those belts is worse than tuning my old SG Special with a Bigsby on it.

[@truantray]

arlingtonhynes You there, get me some fresh petroleum distillate and re vulcanize these tires!!!

[@user-qy4tc9bl2r]

Было бы не плохо на русском услышать.

[@russellscott6485]

I’ve changed 916 belts a couple of times but like you technique, especially the tuning method! 👍🏼👍🏼👍🏼
