This series is still.relevant today, I just purchased a 2k R1 and I'm very familiar with the rebuild sequence but it never hurts to have yours as a reference. Great stuff here.
Thank you, I haven't looked back at any of this in a long time, the video quality is so bad, but I'm glad people get value from it.
and nearly 3 years later, this video saved my butt. thank you!
2 nights to do the shims lol , what a time doin them things huh. in the factory they use a fixture with dial guages that sits right down in the cam bores and a huge selection of shims of course. ...its amazing how quick the assembler can do them.
Years ago chevrolet used a very nice system...it was a typical cam n bucket set up , but instead of using shims they had a screw n wedge system in the bucket that was ajusted using a small allen screw....brilliant!..each full turn of the screw would take up something like .001'' either plus or minus.
How about this , I had a 1979 Kawasaki KZ750B . Instead of a shim in a bucket It had a one piece shim about 5mm thick by 25mm diameter . When I disassembled it due to bottom end bearing failure the valves stems , shims and cam were in pristine condition . There was absolutely no detectable wear on any of the friction surfaces . In fact you couldn't tell one side of the shims from the other !
you are a awesome engine specialist...
I had wondered many times whether a new head gasket was reusable or not after having torqued the head bolts down, so thank you for the reply.
I already knew how to check the valve clearances; when I wrote "to check the valve" I meant "to inspect that buggered valve". I'm Italian and my English is no very good; probably this is the reason for the misunderstanding, sorry.
Now that's a good video
Nice series. Well done!
Thanks for the vids! Guess most of the RN04 engine related stuff is quite similar to the 98-99 RN01?! I got a 99 with 80k km on the clock and need to swap the clutch and check the valves. your vids being a big motivation :)
You can adjust your valve shims without having the head on the engine. Just install the shims ,buckets, and cams with the head on your work bench. You’ll need to disassemble it again anyway.
Your valve retainers were not seated in the keeper fully. That’s why the valve was off
That happened to me too on my PWC exactly the same thing on VX sport 1.1l just as you said something was not right to me and did pull it out and put back in and by magical my shime went back into ... I think that it might be the retainers on that valve that I put somehow wrongly...
Normally, you don't remove the head to check the valve clearances... you only have to remove the valve covers to gain access to the cams. In my case, one of the valves was buggered. The head gasket is a 3 layer metal gasket, so there is no problem reusing the same one after I had torqued the head down once. If you run the motor at all and have to pull the head, you should replace the head gasket just to be safe.
You said, at 1:40, that you had already torqued down all the bolts, so I guess that when you took the head back off to check the valve, the head and the cylinder gaskets were ruined. Were they ruined? Did you use new gaskets when you reinstalled the head?
hi
this is my second mail to you with regards to a leak i have behing the stator cover. as advised by you i got the head gasket checked. the leak is actually from two screws behing the stator cover and in front counter sprocket ( the smaller sprocket). what do you think i can do to stem the leak.kindly advice. i have a yamaha yzf r1 99
Good video, I congratulate you. How much does that engine weigh? I'm interested in putting it on a giant drone
you dont need to take the exhaust cam sproket off..you can unnistall and install cams with those sprokets on...just with an extra effort.
Agreed, its best to leave the sprockets on when re-installing the cams.
not recorded it , the part of the distribution chain , need to know as time goes
What’s the book called, I’m about to redue the head gasket on my 2001 R1 and can’t find any specs.
ughhh dont u hate havin to pull a head after its down! did u use a new one? likely not lol...i wouldnteither givin the cost
Hello, I would like to know the guide point to be able to fine-tune the distribution of the cam follower?
What are the sizes of valve seal of exhaust valves and intAkes?thank in advnce..
I'm trying to replace the o ring on the coolant pipe at the top of the engine... I'm having difficulties... it's very tight and awkward. is there a trick to it? can I use a lubricant or something to make it easier... the engine is still in place so it's hard to get in at it... it's the right hand side pipe.. cheers
bikerboy old post I know but, if you take the cam cover off its easier and you can see the horror of all the grit and filth round there, the bolt comes out then twist the pipe out with the o ring
Why did you skip the caps placement and cap bolt torquing? Specifically, showing the dots lining up with the arrows, or the letter and 1-2 positioning? I had to figure it out elsewhere, I still watched most of your videos, confused why you would skip steps with over 22 videos.
Sorry about that... I look back at these videos now and realize how much better they could have been... oh well, next rebuild I guess.
When you rebuilt the head, did you measure the installed valve spring height?
I cant get the cams to sit down right with the timing chain on. I didnt take the gear off the get the chain back on. When i put the cam caps back on the chain get right tight. Its a tdc to.
Well, not sure what to tell you, make sure the cam chain tensioner is loose and the cam chain guide (the black plastic insert) is removed before pushing the cams down into place - you don't want any tension on the chain. When you push the cams back down it will be a little snug, but not super tight. If its super tight, something else is wrong.
Hey i have a question for u. Could u tell me where the sparkcord next to the exup valve attaches to?.
Are you saying that you torqued the exhaust cam sprocket bolts on AFTER you install the camshaft and chain? How many foot lbs?
Too long ago, I don't remember but its possible I did torque them to spec after they were installed with the chain on; torque specs are in the service manual, I don't have the manual (or the bike) anymore, sorry.
@@repomannv can't believe you replied so fast, and also excellent work! I'm about to replace the timing chain, guides, cam sprockets on a Yamaha fz6. I am trying to use your video for instruction. Do you know of any good videos for step by step instruction on this topic?
May i ask, what is the diameter size of the shim? I want to buy shim kit for my 2001 R1 but i dont know the diameter size. Dont want to be wrong. Appreciate your help
Been too long and I gave away all my shims but if you search for “ Hot Cams Shim Kit Yamaha r1” I think you’ll find they are 7.48mm outside diameter
@@repomannv haha i understand yeah its been 9 years, i just bought used R1.. my bike can cold start easily.. after driving around for a while, it hard to start it back up, need to crank for a long time to run the engine.
What is the tapped clearance I min valve adjustment mm
Amigo me puedes informar sobre la presión de aceite en frio y caliente en una yamaha fzr 600..? Muchas gracias..saludos.
u didn't show top dead center where is that
Jermaine Todd Punto muerto superior..? donde es que..? no, no mi pregunta es sobre la presion del aceite de este motor.. cuanto tiene.
Is the dot strait up in relation to the head or as the engine sits in the bike?
I'm going off memory, but I think its straight up relative to the head.
Здравствуйте а можно перигильзовать целиндры двигателя Ямаха р1???
is the 2000 and 2005 about the same I have a 05 and its leaking from the case split and everyone s saying buy a motor
there are many diffs btween an 00 and an 05 but none of them are dramatic. if you can pinpoint the location of the leak it will help in deciding what to do about it.
+SupermotoJohn
where the cases come together at the back of the engine
+Thomas Neely well, you don't need a new engine just because of an oil leak, if the motor is sound otherwise, pull the head off, inspect the leak location, and maybe you just need a new head gasket.
+SupermotoJohn
the motor split doesn't have a gasket isn't it yamabonded together?
+Thomas Neely sorry, thought your leak was up top at the mating of the had and the motor... if its leaking at the crankcase mating, then yes, thats just some yamabond. go to r1-forum.com and post up there with pics and the crew there will guide you.
Which parts of the engine did you replace ?
I will be grateful if you can write down which parts did you replace to make the engine work good again and what kind of equipment you needed to make a whole rebuild.
Do you work on all 2001 Yamaha R1’s Engines?
Only work on my own bikes, and I’d rather be riding than wrenching 😀
@@repomannv Thank you 🙏 and keep on riding 👍.
Keeper on the valve...
Where is top dead center
