my macanic should have bought this because he had the head in his hands several times right?

[@billross7078]

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

[@twogurls1kuppp]

That is incorrect. Red only way to go on these heads

[@DaveWatts_ejectamenta]

what would be nice is listening how rough it runs before and how nice it runs afterwards

[@michaelpresey2273]

Probably because it wouldn't run at all lol

@@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

@Milan Noah instablaster =)

[@rmatvmc]

@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!

[@LowTierPancakes]

[@bluehuman9375]

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]

@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

79 banditos could that be the exhaust valve?

[@79banditos3]

Wazzup ya one of them could be sticking slightly open also could be intake valve allowing to much fuel in

[@wazzup2987]

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.

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

[@Fox40Racing]

this video was a lot of help for me once you get it its not hard at all.

[@nelsong4719]

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?

[@tylerfalcioni4924]

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 😅

[@ghettohey2388]

Is it possible to just buy all brand new valves and put them in ?

[@rmatvmc]

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!

[@noahsteffens828]

Rocky Mountain ATV MC if I replaced the cylinder head does that mean to go with OEM valves, shims, and springs?

[@robertbrandywine]

Wait! Is the clearance measured between the top of the valve stem and the lobe or when the lobe is up? I ask because I see other videos where they have the lobe pointing up when they measure.

[@spelunkerd]

Yes, at top TDC of the compression stroke, the lobe of both the intake and exhaust cam will be pointed away, to allow both valves to be completely closed by the springs. This takes all the pressure off the mechanism, revealing a gap that you can measure. The gap disappears completely when the lobe is pushing against spring pressure. If you are at TDC for that cylinder, all is good for that cylinder.

[@safy87]

do you have to do all the valve measurement or can you just replace them with original sizes???

[@bzurq4207]

Hello, could i also take the valve clearance service limits from this 07wr and use them on my 03wr would this matter? Or would you not recommend?

[@KEMC4765]

Was there any signs that the valves on this bike needed to be adjusted?

[@jeroen-surf]

Great tutorial! Well done!

[@tylerklassen9770]

How do you know how tight to set the tensioner after re installing cams? do you leave it where it was?

[@rmatvmc]

You'll have to refer to your service manual as each bike will be a little different... You definitely do not want to just reinstall the tensioner as most bikes have the automatic tenisoner which as soon as it's removed will fully extend... If you tried to put it back in this way it'd be way too tight. Most of them you have to reset before installing them...

[@daviddonne7333]

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)

[@2WheeledPatinaThomasC]

Can someone explain to me about the feeler gauges, do they have to slide all the way through to be within tolerance? (1st time doing this) cheers

[@rmatvmc]

They should go through, but still have a slight drag without forcing it. If it goes through without any drag, you might be out of spec.

[@2WheeledPatinaThomasC]

[@cjs990311]

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?

[@rmatvmc]

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.

[@johnnymartinez3745]

Is it a good rule of thumb to say the intake side is always on the rubber coupling side

[@jonathoncatterson8901]

Intake side is closest to carburetor and exhaust valves closest to exhaust pipe coming out of engine

[@alexcain85]

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

[@jacobjo1999]

Great video! Just a little confused on the math to find the right size for the valves. How is that done?

[@SOLDOZER]

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.

[@madddog1411]

[@glock19gen3]

Can SS valves and the associated springs be installed without any other steps? Meaning, is there any lapping needed or can the new SS valves simply be swapped in?

[@rmatvmc]

Yes, they can be simply installed however it's important that you inspect your valve seats and have them re-cut if they show signs of wear. This is best done by a machine shop. As far as lapping the valves goes, you can lap stainless steel valves to ensure a good seal, but as long as your seats are in great condition they shouldn't have any problems making a proper seal without having them lapped. So you don't have to lap them but it's not a bad idea. As you probably know Ti valves should never be lapped. If you have any other questions let me know and thanks for watching!

[@rmatvmc]

Yep! We do it all the time to make it easier to adjust the valves. Just make sure you torque each of the camshaft cap bolts down when you go to take clearance measurements... Install the camshafts and install and tighten down the caps and then make sure the camshaft lobes are pointing in the right direction and take your measurements. Let me know if you have any other questions

[@jonathoncatterson8901]

Link on chain doesmt matter as long as the cams are top dead center and the piston.

[@lifeisgood070]

@@jonathoncatterson8901 I ended up using a paint pen to temp mark the links too. I just have trouble understanding that the situation is correct after the tensioner goes back on. I know it won't affect the current cylinder one is working on, but what about cylinder 1 vs 2 timing. If there are a different number of links connected between the bottom crank and the cams due to the lack of tension. I think you could go +3 links maybe -2 links. Idk maybe i'm just not smart enough to think about it. Within a single cylinder makes sense to me as everything is relative, but having 2x timing chains, 1x per cylinder makes me wonder if they can be timed differently relative to eachother.

[@radrcer]

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.

I just have a quick question about the valves how do I go about completely removing the valves on my 1987 Yamaha xt350. I'm not finding anything online about it. can you help me please?

[@KevinMartin44128]

Why would your valves come out of alignment? Wouldnt they need to be completely replaced because of wear? Im new to 4-strokes. Very complicated!

[@wazzup2987]

Kevin Martin Once you learn and get it you'll be more familiar and know it. This can go with any major work with things.

What would cause all three intake valves to have zero clearance? The exhaust valves are just under spec at .15

[@bgberserk2334]

Would you have to adjust your valves if your atv is popping because my Yfz450r just started popping one day and I was wondering if the valves would have something to do with it

[@rmatvmc]

Your valves can cause popping and hard starting. It wouldn't hurt to start with something more simpler like the carburetor. Go through the carb and clean out the jets. If this doesn't fix the problem, it's probably time your adjust your valves on the machine.

Rocky Mountain ATV MC What if it dont have a carb?Mine is a fuel injected yfz450r

[@rmatvmc]

You could look into cleaning out your injectors and throttle body? Not sure if maybe they could be gummed up a little? Then i'd look into getting your valves adjusted.
