Now that's a job well done 🙌 That new guide is certainly "Stronger" !!! I started this video thinking "No way!!" And I finished this video thinking "Well that was easy... Why didn't I think of that??"
Really great work !! I own a machine shop similar to yours doing the same sort of work, the next thing you need to build or buy is a blast cabinet. working with a clean head is a must and will make a huge difference to your end product
Head should be heated to 300 degrees F to reduce galling and make extraction /installation easier and not break guides but no hotter cuz seats may come loose/fall out. Lube new guides on assembly. More to it than that tho.
This is beast!! I will definitely show this to my boss. He owns a machine shop down here in Montgomery County Maryland. I think he's done this before or at least the other co-worker of mine have done this. This is great for me because I've been wanting to make my own valve guide for my subaru but didn't want to buy brass stopper valve guides due to they wear out faster than steel.

I prefer to drill and ream first. Then machine guide outer diameter between centers. That assures run out between bore and outside diameter to a minimum
One of our specialties at flanigan's machine shop was making valve guides remachining guide holes put in new valve seats with the added other valve work, shave old brass boat prop shafts to make new valve guides win win situation aluminum welding of cylinder heads PS always heat up aluminum cylinder heads before removing guides critical step
I give you credit for ambition and I've made my own guides for various projects but the Yamaha guides are cheap to buy. Warm the head with a plumber's torch and you can drive them in easily with an aluminum drift. Only. 001 interference
This incredibly detailed work and while I would never take away from it, I sincerely hope this was educational more so than anything. There is no way anyone would pay for this at that scale of detail instead of buy a new head. Unless you work for free. I hope not, considering your skill set.

Great video, thanks for sharing. One question, at 5.05 when the reamer comes out you can see a little spring back. Is the alignment of the tailstock ok?
Several errors, the head should be warmed up to 200 degrees to expand the hole, dont use bronze when the rest is cast iron, you can't get an acurate OD from a cracked guide, dont replace the depth setter ring they come off, warm the head up when fitting the guide to prevent galling, once fitted ream the guide to the correct clearance, you will need to recut the seat so it is concentric with the guide, then lap it in, now skim the head.
Great video! I build mx engines from home and just purchased a tormach 1100m vertical cnc mill. What cutters are you using to do the radial cuts on the valve seats? Thanks!
@@PaulXchannel Oh okay, thanks. I love your work. I wish the people that does that type of work in here were like you. Everything you do looks professional and very well done. Thanks for sharing
Thanks. From the manufacturer: AMPCO® 18 is ideally suited where high strength and hardness combined with wear and fatigue resistance are required. Some of the more common applications of this alloy are bushings, bearings, gears, worm wheels, valve seats and guides, hydraulic valve parts, pump rods, guide pin bushings, gibs and slides, etc.
@@PaulXchannel make this question because i broght a honda k20 motor and they have a broked esxhaust guide. The motor have good compression and timing is ok. I thing they work with very hot EGTs and high rpm couses that. Tanks
Here is what a race mechanic told me can cause this. High rpm and speed coming into a corner. Throttle chop (rapid closing of throttle) combined with braking with clutch fully engaged (lever out) can cause severe backlash on the timing chain opposite the chain tensioner. If the tensioner teeth are worn the tensioner can move out giving the timing chain extra slack. This can cause the timing chain to skip resulting in valve to piston interference. They sell an aftermarket performance timing chain tensioner that is not self adjusting. I do not recommend this part unless you are racing and/or very meticulous about maintenance. Replace the timing chain tensioner with a new one from Yamaha.
@@PaulXchannel the American Kibblewhite company has a whole set of 5 for 70 S=US Dollars just seemed like a a lot of work to make the one. love your videos very well done and informative.
2 quick questions 1 Was this done because the OEM guide was unavailable? 2 What happened inside that combustion chamber? One side looks heavily pitted.
Should always recut the valve seat after new guide installation. They never go back in the exact same place. I would have heated the head to make for easier guide removal and used liquid nitrogen for guide installation. Also I would have reamed the guides after installation. With force of the press it can cause a pinch point in the centre of the guide. The jobs ok. But not really amazing.
I like the adjustable press fixture. Excellent idea. Thanks for posting.
me to may have to make one of them
I'm just glad this popped up so I could see the tilting table for your press......I'm off to make my own!
Your workshop is like a dream for every real man )

Owww genial 👍 excelente trabajo
that engine is like 1/4 of a 20v 4age xD
If I sent you an oem part would you be able to mill some? They don’t make them anymore but I have found one.
Do you measure the inner diameter of the Valve guide?
It's the Johnny q90 genius of the moto world, or better. 👍👍👍👍
Matur suwun njeh mas londo
Any reason why you didn't make a whole set of valve guides since everything was already disassembled?
Tem manual de serviço desta motocicleta?
Excelente video really!! Should you use the reamer once the valve guide is installed in the head?
Thanks.
In this case it was not necessary.
Jorge Mercatali that is the preferred method, yes
I make valve guides in Zimbabwe out of cast iron and bronze but finish the od between centers
Good work.
👏👍👌
Good idea tilting adjustable table. But one confusion that same O/D of OE guide and new made replacement guide? ??
Thanks for watching
For less intensive applications would 12l14 be a good candidate material? Say a street / commuter 125, 150cc?
Good job man seems really nice!

Sir, I would glad to know that if your brass one is more durable than the original part (look like forged material). Thanks!
It's not brass it's Ampco.
@@PaulXchannel but does it last for long? And thanks sir, I have just found a new information.

You amazing bro 👌
Thanks
so what is the configuration of the 5 valves?
2 intake 3 exhaust?
or 3 intake 2 exhaust???
3 intake 2 exhaust
@@PaulXchannel thanks
Better to press out hot and install plus hone to size is recommended to take the barreling out.
What grade of bronze are you using?
It is in description
Amazing 😍👌🏽👌🏽
This is just amazing
Thanks
Amazing.
Thanks.
Beautiful machine work. Are replacement valve guides unobtainable for this model?
Thanks.
It is possible to buy.
Great video! I build mx engines from home and just purchased a tormach 1100m vertical cnc mill. What cutters are you using to do the radial cuts on the valve seats? Thanks!

How do you spot the broken valve guide? It was making a nasty sound? Or malfuntion of the engine in general?
When I do a preventive inspection of a engine.

What bronze are you used it?? Is that almunium bronze or what??
everything is in the video
AMPCO 18
Filing good❤️
Is it normal thing i saw at 4:50 the bit seems like a little bend downwards during entering the hole?
This may be the inaccuracy of the drill head
@@PaulXchannel Did they affect the clearence? Nevertheless, Good video u got there mate! Thanks for uploading em.

Warum Aluminiumbronze statt Kupfer Beryllium?
why don't you try Moldstar that's what my shop uses for making valve guides, but its probably close to what your using
Perfect
Good job 👌
great job with the valve guide, head / combustion chamber surface bad. Will you be doing anything with that ?
Thanks.
In the next part.
Wonder if the 250 and the 450 same size head?
different size
You great moovy maker.
hello .. what name and type lathe machine use sir..
Optimum
type series sir🙏
Optimum D 320 x 920
thanks sir🙏🙏👍🏼
Is this music from AM2R?

Most using colsibro copper alloy made valve quides, that is good stuff.
What couses a cracked exhaust guides????
I do not know.
I'm thinking about that too.
Bad timing?
Maybe when the piston meets the valve - then it oscillates.
@@PaulXchannel make this question because i broght a honda k20 motor and they have a broked esxhaust guide.

Original guide was cast iron no?
Yes

awesome work but you know there are replacement guides available from Yamaha for @40 Euro..

apparently the valve tore off

Yes if necessary.
