The question Andy had about the head being on a hotplate I will explain here, I head the heads up to push the valve guides back so they dont stick out in the channel before I start working on it, when done it is the same story but then reversed, heat it up to put them back to there original position
Thank you for the explanation Toine. Excellent instructional vid - for those of us who can read minds...! 😜😎🤣
Those guides look awful tight, the valves should fall right onto the seat without you smacking them😄
@@colbyhutzellfishingvideos4365 not sure what you referring to, I lap the valves is so to be sure they close perfect, the guides are checked on clearance and if necessary corrected either made slightly bigger or being replaced if worn out. These guides are the OEM guides that already did 24.000 km, so again what is your problem.. the guides have not been replaced and beside being pushed back slightly they are untouched..your a special kind of stupid or not internet hero ? Show me your tuning skills if you are so sure of your claims you make .. at least I can back up side of the story with loads of examples, performance increases and reliability security.. so enlighten me and show me your skills..
@@colbyhutzellfishingvideos4365 I thought they were a little tight due to the valve guide seals being in place but no, he fitted seals later. Guides probably had a rolled edge from being moved? Personally I would have checked to make sure there were no burrs on them.and run a reamer through if needed (plus mic valve stems) the aggressive reply is quite 'telling' in my opinion.
@@toinevandenbiggelaar6083 Before you ask, yes, I worked at a Ducati dealers (and Suzuki, Honda, BMW, Yamaha, Triumph Dealers plus just about anything that rolled through the door) I've also done a fair bit of porting over the years and built some reasonably quick road bikes. Also worked on Ian Lougher's IOM TT bike when our shop sponsored him (before he got factory rides)
Wow! He took a lot of material out of those ports. Thanks for the video!
I have watched many videos on CZcams trying to understand head porting and always struggled to understand where the improvements are made thanks to this excellent video and narrator talking through the process I am much wiser than I was 35 mins ago. Thank you very much.
this is a street port, the shape of the inlet and and exhaust stay relatively the same, , a little extra volume and smoothing of the tracts whilst maintaining the overall shape of the stock head, its important to keep the venturi effect of the tract , less is often more, a race port is far more severe , with much more widening of the tract and a more volumetric approach to maximise air volume and therefore top end on the engine.
This is a really nice tame porting job for street use, keeping the intake air nice and fast without modifying the stock venturi shape of the head, you can really go to town with a port job and completely change the nature of a motor, even so far as welding or epoxying sections to build up sections to smooth the airflow or increase the venturi effect on the air for low down , low rev grunt.
its a real art and a lot of fun to get into :)
@@deadprivacy, exacto, + velocidad del flujo admisión, con capa límite turbulenta y aunque disminuya un poco la sección transversal, se gana en velocidad (como ver correr el agua en un arroyo), densidad y partículas de combustible en suspención oír lo que se "atomiza" y mejor homogeinizacion de la mezcla, no adhiriendose en exceso a las "paredes" del conducto (Port). Zonas de velocidad y zonas de amplitud previas al casquillo de válvula para reducir velocidad y transformar en aumento de la presión.. Saludos desde Buenos Aires Argentina !
Top notch work there!! eyes sharp as knives hands quick as lightning and soft caress.! great workshop stuff thanks Andy &Toine.
I bloody loved this! Thanks to the pair of you guys.
so pleasant to watch a pro do his stuff....Its mesmerizing to watch; reminds me of my grandpa working on his tractor; I'd watch for hours and be totally happy. I think this is why I have always loved to work on my own stuff.
Congrts .. Te felicito por tus recuerdos y vivencias en tu infancia con tu abuelo, cultura de familia y disfrutar de personas de vocación. Lo mismo yo con mi padre en su taller mecánico, y especialmente cuando empecé a ayudarlo en sus trabajos (amé los motores) a los 15 años allá por 1983... Saludos desde Buenos Aires Argentina !
Boy does he work quick , just fantastic ,Thank you Toine, Andy , what an insight you are giving us .
Excellent workmanship he makes it look so easy ,which its not.Thanks Andy
Thanks 👍
I love seeing true 'craftsmen' at work. Superbe.
Glad you enjoy it!
Why am I watching this at 1am? I don't even own a bike.
@Spivze Spivatron how did you know?
LOL! same here
It’s been 3 years, I gotta know. Did you buy a bike yet bro?
Now THAT was cool... Obviously very skilled and well practiced in his art. I really like the way he is always checking, then rechecking stuff, and if he changes anything to do with it he checks it again... Cool video dude, thank you 👍
Thank you sir, I loved your don't get Del luded video, that was just EPIC parody stuff ...😆😆😆😆
Good one Toine. I really enjoyed watching you open up those runners. I was surprised at how much material came out. Thanks Andy.
Enjoyed the video. Preciate you giving us your time.
Very good job Toine!
Congratulations!!
Fascinating, great to watch. Thank you. 👍🏻
I booked service with Biggelaar this July, bringing the bike from a different country to overhaul my 996 engine.
Any update on your bike?
A master at work here, thoroughly enjoyed watching this
Loved that therapeutic to watch! Cant wait for him to do mine 🤗
Yours will be super interesting because they’re 2V. I’m keen to watch how much he opens the ports up.
What a master at work! Very impressive! Thank you both so much for the sharing of knowledge!
Love the speed he works at!
Excellent Video Guys!
great video ! thanks for showing us the right way
Great video, learnt to do this on 2-strokes, and did a bit on 4-strokes.... Toine has skills and patience!
Great video Andy. Nice insight into porting for people to get up close for a look. Cheers
Glad you enjoyed it
Nice vid and good to see some of your Vistas down under
Lovely workmanship, a delight to watch and heh heh love the Delsplaning 😁 !
Great video, excellent craftmanship and Toine is also going to port my 999 heads for my caferacer
That is a FULL ON job!!
He isnt just smoothing it.
15% is huge!
Υ ς
lol, i thought you edited the bits out where he blinks - he watches his work like a hawk! thanks for the share both of you. cheers!
Great Bro loved it
This is some interesting shit, keep em coming guys. Laughed my arse off at the end XD
Fantastic vid, thanks. New to desmo valve engines, but I am learning!
Brilliant! Thank you!
Nice porting approach and explanations to methods and why
Amazing video! Thanks!
Enjoyed that great vid
Love this! You can “see” the experience in the way he works, great craftsmanship 👍
A master at work/Bravo.
Love the opening music!
Great video!
Brilliant , thanks 😊
Very good
Grand job
very interesting---thank you
What a nice job dude
Nice video and great craftsmanship! It somehow reminds me to my dentist 😜
This bloke knows his job , well done.
Great video mate
Quality mate.
Fantastic video, clearly a man that knows what it’s all about, nice touch at the end, did he feel epic 😁
Yes I felt epic after showing the dellbollocks reference
Awesome
Still searching every week for some more updates! Would like to see Toine taking us this winter at a journey from "original engine" till modified engine specially with the engine tolerances and Dyno analyzing.
First time I messed with a cylinder head I was 17 and closely supervised by my Dad who knew a fair bit about engines.
I opened up and removed the corners and casting residue from the inlet port, and left it relatively rough as Toine did here.
Not sure if it was the fuel quality back then, or the previous rider doing lots of short journeys with the choke on, but lots of dense old carbon had accumulated in both the combustion chamber and exhaust port.
So after opening up the outlet port, I did indeed polish the holybuggery out of it, as well as the combustion chamber.
Then I skimmed the head using emery paper (nicked from work) and a few thick sheets of float glass. Took a while, but I had it back together again by Sunday lunch time.
Yes of course it ran better. Removing the end baffle from the silencer, and fitting C70 or C90 jets all added up to making my 1972 Honda C50 Cub a Yamaha FS1E beater!
This is where it all began.
Awesome work 👍👍👍👍👍👍😎
Thanks Adam, I'm loving your ST2 project mate
@@ANDY5 Thanks Andy, its feeling like labour of love, never seen so much rot on a Ducati!
Thanks Andy, this is a privilege to see such an amazing Engine artist at work. Cheers Rich.
My pleasure
Engine artists? That's a cookie cutter. Real engine artists use hand for valve lapping.
Thanks for explaining de hole process 🤫☘☘☘
😂
If he ever comes to OZ for a working holiday, tell him to bring his tool bag. I've got 4 heads for him to do. I followed him on the valve shimming only difference was, that took me 2 days to do aaah a master at work. Enjoyed the video.
Awesome. That’ll do.
Nice video broo.. THANKS...
This is a.good vid. Cheers cobba
Very nice!
Thank you! Cheers!
So much work for a head 👌🇮🇹 .
I also drive a Ducati 1198s a great engine 😍 .
Biggellaar are the best 👍
Well he made that look easy!
TOP video.
Excelente trabajo saludos desde Argentina
This guy is amazing, I need to take some notes! Great video Andy!
Glad you enjoyed it!
Hey Andy there ain't nothing like a no nonsense Dutchman doing his thing .....
Godverdomme, he's Dutch?
Nice bike you got there andy
A magician.
Something when you want to study like you are, do greetings from Indonesia 😎😎
Super bike👍
Great stuff, now .... where is my Dremel and black & decker 👍😱😎🤗
Nice!
Looks easy when Toine does it 🤣
This is how I want my mechanic to service my bike, As fast as he can and throw caution to the wind. If there's going to be catastrophic failure in the engine due to negligence I want to find out about it somewhere out the on the road...
have you ever wondered how its possible that a painter made it looks so easy to paint doors etc and when you try it it takes ages and its almost impossible to get the same finish as he does, or any other skilled professional that does make his work looks so easy while a not so trained person takes ages to do the same job and mostly with less results ? well there you go after hunderds of heads and engines its becomes a routine and you dont really have to think about the next step, its so very rare that a engine fails after I have tuned or rebuild it and even then most of the time its due to a failure of a part and not the work done .. Just saying, this particular example in the video the customer already did put a 8000Km on the bike with no problems beside the fact he had to adjust to the increase in power ..
Great and informative video guys! Do you recall which particular brand/size of Carbide bur is being used or where it and the flap sanding stick could be purchased? thank you
what do you call the bit to attach those sand papers? thanks great vid!
Super Vera level sir👍
Reminds me of listening to cricket in my old mans garage.
Hello..Im french..its good job!! i like
Great video thanks for posting! Just curious, when he ports heads just by eye and experience, do you have any idea what the performance difference would be between two identical heads both ported by him?
What’s your flow numbers on this? He had after you done all the work to it?
ANDY!!! PLEASE PORT A 2V HEAD WITH FLOW BENCH BEFORE DURING AND AFTER!!!
YOU WILL BE MY HERO!
Great to see an artist at work! Me, I'm just a piss artist, but were both good at our jobs! Good stuff.........
A master at work...
nice
Hogging out the ports like in the video is going to increase flow but it's going to decrease port velocity, i cringed when i watched him enlarge the valve seat throat area, that head's going to make less power than stock now, all the high hp engines I've seen had epoxy filled intake ports to increase velocity.
Awesome, he is almost like a blue ass fly that knows his shit. Great video Man.
Remember to keep throatnon valvevseat about 88-90% the diameter of the valve on the intake. It'll help low lift flow
I bet Del taught him the proper way to do that.
Hey guys great informative video I m looking to buy a good set of carbide bits but there’s a lot of cheap ones on the internet what is a good brand to buy or where can I get a nice set...keep up the good work
How much power was lost with that head ?
I think You can polish exaust ports combustion chamber and the top of the piston ?
Motor kencang aja di porting juga mmg mantab dahhh
This is probably fuel injected but on a carb bike, would a job like this mean having to reject the carb for the extra room, or would it stay the same and just habe better response because of gas and and exhaust inns amd outs, would that just be smoother transition but not needing more gas, thanks for your time
Maybe I missed it due the fact that I am watching this in bed on low volume while the wife’s asleep, but what where the results? Any change in power delivery, top end?

Good👍👍👍 lake Chanel I'm goes duit tank you very much
I watched a bloke work on ducati engines he sold them new in the early eighties , walsch motorcycles at chigwell
what engine is this
how is the valve diameter proportional to the intake hole? I hope you can reply to comments. Tks
驚きました。
このようなラフな作業の画像をオーナーさんが見ないことを祈ります。
Good joob.
