- Hello everyone and welcome back to the channel!
Here we have the much requested video detailing the valve clearance inspection on the 6th Gen Honda VFR 800 VTEC.
This is a mammoth task and one that costs an absolute fortune at a Honda main dealer or even at an independent.
This is the first part of the task, which I have neatly broken down into 3 separate episodes, the next two parts can be found by following the links at the end of this video.
As promised, below are the links to all of the gaskets that will be needed to complete this job. I will not add part numbers of any VTEC lifters or shims as the part number is determined by the thickness and would therefore be entirely pointless!
Bear in mind that the combined cost of all of the gaskets below, which are all genuine Honda items is £231.41!!
Valve cover gasket Front - Part Number - 12391MCW000 - Qty 1 (Item 7 at the link below)

Fair play. The entire VFR VTech world was waiting for this. Thanks
To be honest, after watching that £800 with a dealer is a bargain! Much bigger job than I thought. Great video Kev 👍
Did this job on my 2014 VFR, didn’t want to pay $1000 in labor. Bought the special tools and still came out ahead with the savings. Although time consuming, I’m glad I did it because I had two slightly tight valves, one of them a VTEC bucket.
Good work 👌🏻😎
Hi Kev - Great video! I'm half way through doing mine now, thanks to you. I cable tied the cam chain to the sprockets just as an added measure to ensure the chain stays in the same place. Thought it might help others!
been waiting for this one thanks for posting
Your welcome bud! 👌🏻
side note: vtec valves have x2 service limit than normal valves. so, if you don't wanna fiddle with the v-tec valves just check the normal valves which i did when i had my valve clearence.
Almost 3 times the tolerance! 0.03mm versus 0.08mm 👍🤓
Hi kev hgv mechanic myself as i have said before in other clips a lot to take off mine a 8th gen one same lump as yours mine not due yet but will be by next year merc trucks are a big job when you do a top end service i work for merc My other 2 750 model viffers they are easy to do .The early 750 is on the old tappet adjuster lock type the other one is on shims done both of them a few times never had to adjust them early ones as you know are gear driven cams . Good vid kev you should be a full time mechanic these days to get a hgv mechanic is like rocking horse poo vast short age of them we at merc struggle to get any one to come even for a interview. My self do night shift at merc always loads to do due 2 lack off staff its a world wide thing lack off hgv mechanics one thing for sure i will be never out off work .
Thank you for this video. I've wondered why this job is so expensive to have done in a shop; now I know.
I had several reactions. First, I worked as a software engineer for USAirways maintenance and engineering for 16 years. Several times I got to tour their maintenance facility in Pittsburgh, where they work on stuff like engines (they have a test cell where they can thoroughly test a jet engine in operation; I was there when it was in use), fuselage parts, electrical components, and coffee makers (you can't fly passengers without a coffee maker). I can't see much difference between working on this bike's engine and a 737, other than scale. In fact, the 737 engines might be easier (just 3 bolts to remove and off it comes!).
Second, it's clear that this engine was designed for use in their racing bikes, where ease of maintenance is secondary to performance. (There's a pit crew for maintenance.) Compare this engine to the one in the NC750X. Checking valve clearances on the NC750X is simple (at least, from the video I've seen): remove the radiator and a few other bits, and there the valves are, easily checked with a feeler gauge and adjusted with screws. The NC750X engine was designed so that even posers like me can work on it. It's not nearly as much fun to ride, but it's easier to live with.
I can't wait to watch parts 2 and 3!
They are out mate! Parts 2 & 3 are linked at the end of the video 👌🏻😎
@@KevsShed I will watch them!Got to see you put it all back together.
Great video, gripping stuff, even though I have a 5th gen and not 6th. Would a clean lint free cloth be a good idea to gently poke into the chasm into the engine and prevent anything falling in as you remove or refit bolts and washers? I think this is what I would do as I am a bit clumsy. Thanks for making this video series of this job. Not for the faint hearted!
Yes absolutely, especially if you are prone to dropping little bits! 😬
Thank you for very well done video...much appreciated!!!!!
I just paid CAN $1800 to find out I have a cracked cam holder. Of course you cant just buy the one part... Honda sells the whole top end kit for $2000. So I went bought me a Moto Guzzi instead. Then I just met a machinist, says he can weld my cam holder then machine it.
Only catch, hes retiring in a month. So Thank to your video, along with my maintenance manual. Ill be ripping my vfr apart tomorrow.
Yeah the cam caps are machines together with the head so that they are truly matched otherwise the camshaft wouldn’t fit properly, good job you have someone that can do that job for you! 👌🏻😎
Well done kev
Cheers mate
Always get a delay in notification for live videos. Guess it’s in between the phones refresh for TH-cam. Anyway, i missed the start so back to watch again lol.
Strangely, my wife didn't get the notification either! I reckon she's turned them off! 😂👀
Love your work.
Prevention is better than cure,
in respect to dropping things in the crankcase
Excellent tutorial! Awesome job man!
Glad you enjoyed it! 🤓👍
Thank you
Kev Thanks for sharing that. I am planing to do this job myself although I had Honda VTec Vfr 800 before. Had also VFF 800 fi, now got pleasure to own Honda VFR 750 02 reg. Planing to do this job myself. My dealer 2 year ago asked 600 pounds for this job. This year i asked how much would 750 vfr cost delaer quote me 750 quid. So will do it myself. Do you have any tips on how to put camshafts back in position in head so they exactly where they were. I seen some tips like cable tie on sprocket and chain and mark another camshaft with marker and do one at the time. Seen people how easy to misaligning by one tooth and bike was loosing power etc. ? Any tips on that? 750 model with sprockets through middle of head. No chain, no VTEC valves. 800 sprockets were on side of head. Never done this before. Like to try to make sure bike spot on. No much history on my VFR has 46k not sure valves ever been done
can you please do the thermostat replacement guide video?
is your valve clearance good? I'm getting some strange vibration that's coming through my gas tank into my thighs and its like a rattle, Just did the cam chain tensioners and it went away for a few weeks and then came back. I can only hear it when my thighs are touching the gas tank.
I love to watch your vids! Especialy from the VFR. What stand are you using! It looks very stable.
It’s an ABBA skylift bud, here’s a link ebay.us/RqE6rw there’s currently a 20% off code on eBay at the moment which is a heck of a saving! 👌🏻😎
@@KevsShed That is a big saving. It is a little expensive, but I think it is wrth it. Thanks for the link. 👍😄
Sir, I have a 2007 VFR800 25Year Edition, but my back is very uncomfortable because my handlebars are very low, I see that your handlebars have been changed, Could you tell me where to buy them.
Thank you !

I have done it, and replaced the tensioners and rails too. It's a cock of a job...
It certainly is! 👌🏻😎
Fairly extensive I see and through my own research for my bike too. Do you recommend anybody to do this job if it's there first time doing it?
To be fair it was the first time that I’d done it! Hard to say really, it depends on your knowledge and experience I guess! 👍🏻
It was my first time when I did mine. Read your manual carefully, take your time, and it will be fine.
I know this is a little late, but I find Partzilla (not revzilla) . Genuine Honda parts are a LOT cheaper. If you make the postage worth your while and order a few bits it saves you a fortune even if HMRC take their import duty.
Thanks for a great channel Kev. I have a 6th Gen with a slight ticking noise that sounds like its coming from front left of the engine. when the oil is cold its not present, do you think its time to look at the value clearances? 29k km on the clock.
IAC = Idle Air Control iirc
How would you know if a valve is on its way out without removing anything?
Now I have a 98 vfr800fi have had for neerly 15 yrs runs great never any issues took good care of her shes my baby but how similer is it to my 5th gen I deff think I meed to check mine no issues or sounds but I deff dont want any so how close are these to in comparison
The valves on the 5th Gen are just like the non-VTEC ones in the 6th Gen, all 16 valves are regular valves and to check them is easy! Cam cover off, turn the crank to TDC on the compression stroke for each cylinder and gauge them, no pulling of camshafts etc!
@@KevsShed awsome I have a rule since ive started riding im only 1 to work on my bike I wanna know how to do it and I know done correctly. And I love this bike have worked on many many diff bikes by far prob 1 of best built biks ive messed with and I'm deff goin to do this thank you for your videos def helps lots. Thank you very much
Im taking the front cylinder head off my 03 i set mine to timing mark 2 is that right? I already took the cams off and everything
Excellent thank you
Sod that. Gonna buy me a 2 stroke. Or a Guzzi.
😂
@Kev's Shed Seriously though I loved the vid. I really appreciate your helping me to make an informed choice. I have just retired and am looking to return to biking after 18 years or so. VFR was on the shortlist (largely due to fond memories of watching 1980s road racing - V Four Victory etc. However funds may be too tight for complex professional work, and although I'm a pretty competent spanner wielder my dodgy back and mild arthritis now makes this a chore. If I can get a bike that's had the work done recently then great; I doubt I will ever put enough mileage on to need it doing again. How much simpler is the job on a 5th or earlier generation with gear driven cams?
@@neilanyon4792 Much simpler on the 5th Gen mate, no need to take each camshaft out twice, only need to be removed if a shim is required, it would take half the time!
@@KevsShed cheers mate. Might be the way to go.
Hey Kev really enjoying the videos! Noobie question just wondering how much work would it take to replace both cam chains whilst you've already got the cam shafts out? Cheers
Not too much more work mate, I’m not sure how easy it is to remove the chain from the crank with out further disassembly without checking the manual, but with the camshafts removed you are certainly most of the way there! 👍🏻
@@KevsShed cheers mate!
Are the non V-tec VFRs simpler to do valve clearance check? Been looking at getting one of these V4s but wow it seems intimidating
Yeah much simpler, there’s no need to remove the camshafts twice! Only the once if any shims are required! Other than the first camshaft fit and removal, the process will be the same from then on! 👍🏻
No spark what do I do driving me crazy
Start by telling me what you have checked so far? Coils ok?
@@KevsShed coils are good fuel pump good was running now no spark could it be ecu
No spark coils are good plugs good
And how do u test ecu
Is that a Mitas sport force + tyre on a race bike behind you?
Never heard of that tyre to be honest so no. 👍
How different is the valve clearance on the 8th gen?
I’m not certain bud, I would make the assumption that it is identical though. I don’t have a Gen 8 manual to be able to confirm I’m afraid!
makes you wonder if the 16ks worth it?
tbh, if someone wants a VFR i recommend em a 5th gen. easier to maintain and no vtec bullshit.
The induction sound when the VTEC kicks in is quite awesome though! 👍🤓
For the average person, it takes quite a long time to do 16k on a bike! Granted there are some who use them as year round commuters but for those who only use them for fun on nice days, 16k can take a few years!
@bountythumper, I quite fancy getting myself a 5th Gen too, the sound of the gear driven cams reminds me of a supercharger!
@@KevsShed I'm thinking to sell my 6th to get a 5th gen.
