Fantastic step-by-step guide to doing a job that is often deemed more difficult than need be. This video is definitely confidence inspiring, and gets me thinking the process is totally within the reach of an amateur mechanic. Thank you for posting this.
I see "red" RTV silicone sealant on the head to help seal the valve cover gasket. As a 40+year Yamaha/Honda factory trained Tech, (now vocational/technical high school Powersports Instructor) I recommend to my students to use Yamabond-4, much cleaner than the red
I heard about this scheduled maintenance a little while ago and was dreaded by it. Thank you for showing me how doable this work is, even though I’d rather not have to do it 😂
@@michaelpresey2273 Ofcourse it would, but usually u dont hear the difference cause its very little. Tho if the clearance gets too low u might hear weird sounds and stuff :D
@@philippammann9250 my dad recently bought an 05 wr 450 and we think the clearances are off as well. It runs really Inconsistently and backfires a lot. We’re hoping by doing this we can fix the rough idle and inconsistent power.
Sorry to be off topic but does anyone know a tool to get back into an Instagram account?? I was dumb forgot the account password. I would love any tricks you can give me!
I was sceptical about doing the valves myself but after watching this I'm deffinetly not paying a shop to do such an easy job, awesome video! I plan on picking up my shims from your site aswell
Attempting this job for the first time on my bike, I was confused looking at the workshop manual how to reset the timing chain tensioner, although you only breezed over it, I have it worked out now thanks.
@@rmatvmc Bike is running better! Thanks a ton for the excellent video! Will be using again as a refresher when I check/adjust the valves in the future!
@Kevin Martin I'm not 100% sure what you are referring to when you say valves come out of alignment but as your valves wear they tend to stretch out in a sense causing the clearances between your valve buckets and the lobes on your camshafts to get smaller which if they get too small can actually hold the valve open causing compression problems and starting problems. The valves can also slowly wear into the cylinder head reducing the clearances also causing problems so it's crucial that those clearances are regularly checked and adjusted correctly to ensure easy starting and for the motor to run right. You adjust those clearances with different thicknesses of shims. If the clearance was too small you would go to a smaller shim to open it up a little bit. You need the timing of the valves to be spot on and the valve clearances to be adjusted correctly in order for the bike to run properly
Rocky Mountain ATV MC How tight do you go on the cam chain tensioner? Until it is tightened down all the way? Is there suppose to be any slack or play at all in the cam chain?
Rocky Mountain ATV MC OK thanks for your help and advice on that big job I have ran into on this bike think it didn't need jug pistion rings huh valves all along my mechanic is fired he should have bought that I think huh!!!
You make it look easy! This is the best video break down of this procedure I've seen! My car runs this painfully complicated shim/bucket system too but its got a bunch more valves :(
@Kevin Martin Titanium valves will have different coatings on the valve face which will affect the life of the valve and how often you have to actually adjust the clearance. We've seen older YZF's with the stock Ti Valves go years without adjustment and be fine... Stainless Steel Valves on the other hand are hardened steel and tend to last longer than the Ti valves and generally require less maintenance than the Ti valves. The only downside to the steel valves is the weight difference which isn't significant but with the Ti valves being lighter they take less force to open and more importantly less force to close avoiding valve float at the really high rpms. We always recommend replacing the valve springs when replacing valves with the correct springs for the valves you are installing. The stainless steel valves will require a little heavier duty spring to handle the added weight but as long as the proper preparation and steps are taken for installing the new valves whether they are Ti or SS you shouldn't have any problems. Generally if you are looking for longevity SS valves are the way to go!
I don’t know why it took me over 20 rewind to learn how to do the math but I just got it figured out. Thanks so much. Just need to get my shins in the bike and go ride again.
I can't belive we use to take my race 250f to a shop 2 times a year to get the vavles adjusted🤣. Its so easy after watching this video. Feel like a dummy paying a shop to do this for the years I raced.
Well produced video, as all of RM videos are. I have already used the fork seal replacement and tusk light kit install using your videos. Can see everything clearly and easy to follow. This makes me want to buy everything from RM, and I do! Thanks! I'm gonna save a bundle doing this myself.
This video SAVED MY ASS!!! Got my bike open and to the shims and thought.....wait...how do I do this. Just so happens I have a 08 wr250f so this is perfect. Thanks
One of the best instructional videos on TH-cam! Good job. I'm working on an '81 GS850 Suzuki. I'm a Harley guy too...wish you guys published videos for those. Anyway, great detail, concise, and good to have the caption along the video.
I haven't found much for a '79 Honda CB750F DOHC, but you explain the math process pretty well here. I hope I can use this (X4) lol, and get my box project running this week, wish me luck~
@Dalton Sigler If it ran fine the last time you put the bike away timing wouldn't just come out. I would first look at bad gas and possibly a clogged jet in the carburetor.
sgim is 1,55 and if will be 1,20, is also close much the valves i need nuber 0,60 but not exists..if will be install the minimum 1,20 wat kilimeters can go more with this??i mean till i will found new valves..can be one year wait???
bigkatunas The 4 strokes can go much longer and better life with daily maintenance than 2 strokes. 2 strokes are a pain to deal with but they're all good :)
+Rocky Mountain ATV MC @rockymountain oh ok that makes sense now. If you had titanium valves wouldn't they stay within the proper clearance for much longer like the YFZ450R I believe. Thanks tho all your videos are extreamly informative and helpful!
Excellent how to. 2 questions. Why are some shim buckets like my 6 cylinder Honda Gold Wing only require a check every 54,000 kms? Why is the the new high performance Honda CB1000RR-R scrapping shim buckets for fingers?
I have a 2000 yz426f and its sat for about a month and when i tried starting it it would only run for a few seconds or not run at all and backfire alot. So i was wondering of this is just a crappy gas problem and dirty carb or possibly the timing became off the last time i rode it? Thanks
Can you tell me the TOP current ATV's that have SHIM cam adjustments for their engines? I DETEST the stud type adjustment setup s on mower engines etc, and was NEVER good at it. JUST SUBSCRIBED !
79 banditos Ok could it also be a carb problem? Too much fuel or to lean and the carb needs to be adjusted. I'm curious because the guy who is selling a bike says he has took Great maintenance of it and that he did daily maintenance that helps the valves especially for longer engine life in the end.
I have a 07 king quad 450, with 1100 miles/165hrs, runs great, but will make a slight ticking sound after it warms up, was wondering if valves might need adjustment? Any ideas thanks great video
aaronveal123 Napoleon, don't be jealous that I've got a part in an instructional video for Rocky Mountain ATV/MC. Besides, we both know that I'm training to be a cage fighter.
Forgot to mention that there is 2 times the piston is at top dead center, one is top dead center compression and that’s when you measure your valves. I bet 100s of people measured there valves with the lobes not in the right spots lol
David Burak You can yes, but you will still want to shim the new valves to your machines specifications. Most likely they will need some adjusting. Thanks for checking out our video!
well i guess i am going to need an air conditioned shop and a motorcycle stand with lots of lighting. What bike needs the least valve adjusting? I miss my 84 VF750F. Never had to do anything to it. Blasted YZ426F.
Can you clarify. If you didn't mark the chain link and then the cam sprocket position with a marker pen before removing it, then how do you know you got the cam sprockets back in the right relative position. Yes, i know you need to also count off the links as per the manual I didn't think you could measure all the clearances without rotating the crank so that the cams were at the 3 and 9 o'clock positions ( i e TDC) but you did them all together. At 7.42 with the middle valve having zero clearance, you subtracted from the current 1.63 shim. Shouldn't the .15 be added to the 1.63 because you want to lengthen the valve train (getting the valve to be further away from the seat)
What about going up like for instance my 150r needs a 25mm exhaust spec but I'm at 35mm with exhaust shim size being 2.10 so if I swap out for a 2.20 shim that would give me 10mm more clearance making my spec 25mm ✅ is this correct I'm overthinking here 😅
Ignore all the confusing metric BS. Measure in thousandths. If the range for the valve clearance is .005 - .007 thousandths and yours is .006 or .007 then you're fine. If if measures .005 then bump it up. Shims come in .05mm increments. .05mm =.002 thousandths. So if you clearance is .005 thousandths (bottom of the range) and your shim measures 3.00 then put a 2.95 shim in it and that will give you .05mm more clearance or .002 thousandths more clearance bumping the clearance from .005 thousandths to .007 thousandths.
Your service/owners manual will tell you on how often your bike needs to be inspected. You'll know your valves are done if they show signs of pitting, small porosity markings causing the valve to not seat correctly and or excessive carbon build up that won't come off. You'll also be able to tell, by if you cannot shim the valve within the recommended valve clearance. Those are all good indicators that your valves have expanded and need replacing.
One stupid question, but just for make sure, the oil and gas should be drain out ? thanks. I'm looking a dirty bike suzuki 250 from a friend , his told me his has tried ajust the valves but his couldn't , the that why his bike has a little noise, I'm almost buying the bike from him and I'm looking for possible ways to fix it =)
There are two great things in this video: the procedure showed (it helped very much to adjust valve shim in my 2012 CRF 250 R even if the engine is different) and the soundtrack. Thank you very much :D
Question: my CBR600RR has .007-.009" for inlet and .010-.012 for exhaust clearance. A few measure .007-.0075 and .010-.0105. Should i adjust the shim size if tight but within spec? Do shims only come in .002 increments? If yes, then any adjustment would provide excessive clearance.
So what if you dont have a stock engine and have performance aftermarket parts for a race engine and have aftermarket cams. How do you go about adjust valves then.
My atv has two intake and two exhaust valves. Someone looked at my motor to determine what was wrong with it and ended up taking both cams off. Is there a difference between the intake and exhaust cams physically?

Good illustrations. My question is, would it be ok to change out all the shims with factory spec shims each time I do a valve check?
Ok but what if you need to go down in spec and not up??
Love videos.. would be grateful to have more videos for 2017 crf450r.
So if the Valve gap is less than tolerance of the low number you need to take shims out in order to get back into specification
nailed it once again! thanks for the video post.

Thanks for watching!
I'm glad I bought a 2 stroke !
I'm glad I bought a 4 stroke !
do you have to do all the valve measurement or can you just replace them with original sizes???
How often would check your valves on a Yz450f that’s mostly on trails? How many hours would you say?
50 hours if you arent banging it off the rev limiter all the time.
Is it possible to just buy all brand new valves and put them in ?
David Burak You can yes, but you will still want to shim the new valves to your machines specifications. Most likely they will need some adjusting. Thanks for checking out our video!
Rocky Mountain ATV MC if I replaced the cylinder head does that mean to go with OEM valves, shims, and springs?
how many years of manufacture is this machine yz250 ??? please answer .. I need to find parts
well i guess i am going to need an air conditioned shop and a motorcycle stand with lots of lighting. What bike needs the least valve adjusting? I miss my 84 VF750F. Never had to do anything to it. Blasted YZ426F.

I didn't think you could measure all the clearances without rotating the crank so that the cams were at the 3 and 9 o'clock positions ( i e TDC) but you did them all together.
At 7.42 with the middle valve having zero clearance, you subtracted from the current 1.63 shim. Shouldn't the .15 be added to the 1.63 because you want to lengthen the valve train (getting the valve to be further away from the seat)
Awesome video! Will be doing this on my 2003 Yamaha FZ1 soon.
What about going up like for instance my 150r needs a 25mm exhaust spec but I'm at 35mm with exhaust shim size being 2.10 so if I swap out for a 2.20 shim that would give me 10mm more clearance making my spec 25mm ✅ is this correct I'm overthinking here 😅
Great video! Just a little confused on the math to find the right size for the valves. How is that done?
Ignore all the confusing metric BS. Measure in thousandths. If the range for the valve clearance is .005 - .007 thousandths and yours is .006 or .007 then you're fine. If if measures .005 then bump it up. Shims come in .05mm increments. .05mm =.002 thousandths. So if you clearance is .005 thousandths (bottom of the range) and your shim measures 3.00 then put a 2.95 shim in it and that will give you .05mm more clearance or .002 thousandths more clearance bumping the clearance from .005 thousandths to .007 thousandths.
i am new to this shit but if you put a 2.95 shim in which is smaller wouldn't that make the clearance lower
How often is a checkup on valve clearances the norm ? And also how does one know when to change the valves vs getting larger shims?
Your service/owners manual will tell you on how often your bike needs to be inspected. You'll know your valves are done if they show signs of pitting, small porosity markings causing the valve to not seat correctly and or excessive carbon build up that won't come off. You'll also be able to tell, by if you cannot shim the valve within the recommended valve clearance. Those are all good indicators that your valves have expanded and need replacing.

There are two great things in this video: the procedure showed (it helped very much to adjust valve shim in my 2012 CRF 250 R even if the engine is different) and the soundtrack. Thank you very much :D
Question: my CBR600RR has .007-.009" for inlet and .010-.012 for exhaust clearance. A few measure .007-.0075 and .010-.0105. Should i adjust the shim size if tight but within spec? Do shims only come in .002 increments? If yes, then any adjustment would provide excessive clearance.

So what if you dont have a stock engine and have performance aftermarket parts for a race engine and have aftermarket cams. How do you go about adjust valves then.
