Great video. I just checked and adjusted my valves including my first ever shim under bucket adjustment, using your video as my guide. Having just retired from 30 years as a teacher, I feel qualified to say that you would make an excellent teacher. Thanks for the help.

Best AT valve explanation yet. If there is cam position that allows inlet and exhaust adjustment, I'm not sure why Honda specify three positions for the process. Just do as you are told, I guess. Thanks Mark!

The E1 position doesn’t make sense as piston 1 is midway down the intake stroke. The piston should be at TDC on the compression stroke the same as it is for cylinder 2.

Just a hint, you can zip tight chain to a sprocket and remove it from the cam altogether and hang it wit a pice of wire or screw driver, depends on the bike and amount of space. Then when you’re putting it back on a shaft it’s a bit easier as you don’t have to position chain. It helps even more if you have to deal with two cam head.

really good 👍🏽 thanks for the inside. You can ask Honda to change large service to a small on even, so they don’t have to touch the valves at 20t or so, they will be even fine at 50t, in fact no need to adjust them until you hear them I got told
@stalincat2457
@stalincat2457 Жыл бұрын
That is very poor advice. Normally the wear of the valve vs valve seat makes the valve lash decrease. You cannot hear this. Eventually the valve doesn't make (enough) contact with the seat to dissipate it's heat and the valve will burn or break, ruining the cylinder head (burn) and maybe the cylinder and piston (break). Please don't skimp on preventive maintenance untill you hear things breaking down.

@@stalincat2457 Yes, but in general on a normal used AT that makes 50t without valve adjustment, wont need a check at 20tkm which reduces the bill from 1200AUD to 300AUD! I am talking about the first 20tkm service. There are two ways uniquely the AT drives its valves, one is the old fashioned way by pushing down a lever on them. If that needs adjustment it will be surely noticeable.

I am aware that with Honda engines there's rarely any adjustment necessary. However, telling people that they should just skip it till 50t or until they hear their engine rattle is weird advice. What if I told you it is cheaper to never check valve clearance on a Honda VFR Vtec motorcycle but just ride it till the engine blows and then install a used engine? I may be right but that's just weird advice ;)

@@stalincat2457 I believe people are not so stupid to understand, when I say ‘ask your Honda dealer for a small 20tkm service instead of a full blown one, they will understand. Its about the low km one will regular use on the bike. If the dealer accepts and it doesn’t mess with the warranty... thats what we did. Who wants full cover and security can go for it, as you can change your oil all 5000km, but there are options. Thats all what I am saying, there are options where you don’t have to throw out 💸 for no reason. manage your money

I cannot condone skipping service work or extending the intervals. If the manufacturer says you check it… then you check it. Cost of ownership is an eternal issue, but it is rather arrogant for any of us to suggest that we know better than the manufacturer, and for every few owners who got away with saving some money there will be one who wishes he paid more attention to the service schedule.

Fantastic video and great help! One question: How long did it take to remove everything just to be able to get to the valve covers? :-)
@ducatiparts110mb
@ducatiparts110mb 4 жыл бұрын
The first time a couple hours. After that about one hour. Honda seems to love making things overlap each other so you have to remove loads of stuff to get to the bit you're servicing. Full details in the book available from www.marksmotorcycleparts.co.uk

Excellent tutorial, I've been tearing down my AT the past couple of days. Been taking it slow as I'm stuck at home and have no rush. Two questions, did you use the original gasket and did you use any sealant on cut out end of gasket. I've read some people do some dont, was wondering what your opinion was on this? Cheers

Yes, its best to use sealant around the cut out for the camshaft. I use ThreeBond.

In the video you explain that if the final adjustment is off at the end of the process, you can center the clearance by adjusting the rockers themselves. This sort of begs the question, why not skip the shims and just adjust all the rockers? I could see that if you are getting out of range of rocker adjustment then you'd need to fit new shims.
@ducatiparts110mb
@ducatiparts110mb 4 жыл бұрын
The rockers adjust only the exhaust clearances, and the shims adjust only the intakes. 1 Check everything so you know what you are dealing with 2 Remove cams and adjust intakes if necessary 3 If you have removed & replaced the camshafts, or if you know the exhausts need adjusting, Check and adjust exhausts. If the exhausts measure up just fine in step 1, then you remove & replace the cams, you need to recheck and if necessary adjust the exhausts in step 3 because the action of removing & refitting the cams might have affected the fitted exhaust clearances.

Great video. It serves as an instruction for me. It is worth mentioning a slight discrepancy in the alignment of the marks on the sprocket with the T1 mark, which results from a stretched timing chain. The instructions say that you should aim perfectly at the horizontal line above the T1 mark. When the chain is stretched, the marks on the sprocket are not parallel to the housing. When the gear is set parallel to the housing, the T1 mark is set at the height of the letter T1 and not at the height of the horizontal line. I'm doing it for the first time... and my conclusion is that valve clearance should be measured when the gear is parallel to the housing, even if the T1 mark slightly does not coincide with the mark on the housing. Can you confirm that ? Thak You. Paweł.

Techically you're right, but don't overthink it... So long as the cam lobe is well away from the follower, the position of the cam does not matter as the base circle is a constant radius.

I’m assuming that the exhaust valves use set screws because they are more likely to need adjustment more often than the intake valves? My 2017 AT has 12k miles. I hear no ticking, it burns zero oil and it’s power is spot on. Is it really worth the time it takes to tear the bike down if you have zero symptoms?
@ducatiparts110mb

Honda will have all manner of 'good reasons' why they made it that way - my personal belief is that they just like taking the complicated route sometimes. Yes its always worth checking at he specified interval. Power and noise change imperceptibly as the engine ages so you can't really judge its fitness that way. Whilst you should find that everything is in tolerance, my 6000 mile bike needed several valves adjusting when I serviced it for the book. I would not have guessed that from the way it ran, but afterwards it ran noticeably better.

Check every 16000 miles. You don't get any signs other than what the feeler gauge says - the engine will get slightly louder / rattly / rougher running, but by the time its noticeable you'll have left it far too long.
