Use the 10mm offset wrench to loosen the locknut and use the 4mm wrench to turn the adjuster screw. The 4mm adjuster screw works just like any nut or bolt — clockwise tightens reduces the inspection gap and counter-clockwise loosens expands it.
Always keep in mind that we are dealing with very slight variations in tolerance, so most adjustments only require turning the 4mm adjuster fractions of a turn to see results. Once the inspection gap is large enough I like to put the. It being there helps me feel when the adjuster is close to the right place AND it helps prevent the adjuster screw from rotating when I tighten the 10mm locknut. Once an adjustment is made hold the adjuster screw with your 4mm wrench while you snug the locknut with the 10mm offset.
With the locknuts tight go back in with your feeler gauges and verify that your settings are correct, sometimes torquing the locknut can skew the gap slightly. Just like I mentioned above, the end goal is to have the. Now that you have a handle on the process it will make it easier to adjust the exhaust valve even though it is more difficult to see and get to. At least there is only one exhaust valve per cylinder instead of 2 like the intake valves.
To adjust the exhaust valves follow the exact same procedures outlined above, just be sure you use the proper size feelers. Once you have all the adjustments made go down to the crankshaft and turn the motor through several complete revolutions to cycle the motor and valves. Now repeat the entire process by setting the crank to the proper indexing mark and checking the valves again. You need to repeat this process over and over for each cylinder until all 4 intake valves and both exhaust valves are within spec.
Each number is a step, so just follow them in order. Reassembly Remove all the O-rings from all the inspection covers, you should have 4 valve inspection cover O-rings and 1 crankshaft cover O-ring:. If they all look fine and they usually do then carefully coat them with silicone grease. Silicone grease is also used to repack faucets and plumbing fixtures. Be sure that what you get is grease , you want something in a tube or a tub — not a spray.
Now reinstall the O-rings into the covers and then reinstall the covers on the bike. Remember to install the covers first and the bolts second so the covers can prevent you from dropping a bolt inside the motor.
Put all the hoses, wires and hydraulic lines back where they belong and reinstall the zip-tie on the frame backbone that holds everything in place:. Reinstall the spark plugs using anti-seize on the threads and dielectric grease in the plug boots.
With the spark plugs properly seated you can reinstall the chrome plug covers, the airbox, the gas tank , and the seat. Afterthoughts This is a daunting task for an inexperienced wrench turner to attempt, but after doing it a few times you quickly begin to see that the bulk of the work is really in getting the bike stripped down to get to the valves. Having all that junk out of the way makes subsequent valve jobs that much easier. I always recommend that riders learn to do their own maintenance and valve adjustments are no exception.
In fact, I often think this is one of the most important jobs you can learn to do yourself. My reasoning is simple — If a shop lies to you about doing maintenance you can usually tell with a visual inspection. I know for a fact that there are Honda dealerships who charge customers for valve jobs but just park the bike and return it to the customer having never touched it.
The next time you get your hands on a set of feeler gauges find 2 that are. It is not intended to replace the above instructions for anyone except the most experienced mechanics because there are a few areas where it is lacking and minor mistakes are made. Great info, especially for us less technically inclined. Mike, Thanks for the info.
I have been coming to your site before the start of all my VTX projects. Vid is ok, but some mistakes mentions twice exhaust when it is the intake.
Does not show the mother of all adjustments, the rear cylinder. Please re-post, Thanks for your time and efforts over all these years. I appreciate the effort you put into this site, its been so helpful. I hate to pay for jobs that I can do myself. It gives me the satisfaction of knowing exactly what was done. I am a professional racing and street mechanic and I thought your instructions were spot on! I even picked up something which I have never done before and that is a piece of string to tie the tools in case of dropping them into the motor.
I have never done that before I guess I have just been lucky never dropped any tools inside the motor. I move very deliberately maybe even slowly. But I have some heavy gauge fishing line that I am going to try that with really always better safe than sorry. Thank you sir. Sincerely Eric Kent. Thanks again for the info. Going to tackle valves this winter, while we are butt deep in snow up here in Wisconsin. Good tips, good demo. Maybe Ill give it a try. Thanks for the write up.
I will do my own valves and save big time. The dealer said it would be a 10 hr. What a Crock. They were suposed to check them at the 8K inspection I doubth they did. I now have 20K on the bike and will know for sure. As usual bare you have done a great job.
Been following your guidance for years. Now if you only had a sight for for my harley.. Nice wright up with the step by step instructions for us do it your selfers,i was going to have the dealer do this but i will do it my self now. I worked slowly and carefully, and it took me a very long time. However, your instructions were invauluable. I really appreciated all of the extra tips. Before I do the job again, I am going to figure out some way to make working on that rear exhaust valve easier.
That was rediculous!!! Thanks for the help. Great info, Im a new vtx owner mine has miles and I was wondering how often dose the valve train need to be adjusted or checked? Also i liked your info on oil changes, thanks for your help. My best friend has a vtx he bought new and had the dealer do his maintence, partially because it was included with the purchase, and he is finding out now they didnt do all they said or what was required.
Damage DONE! One of the best no BS directional write-ups I have read! I am saving it and I will use it very soon. Thank you. Thanks Bare! Thanks again for the info. Going to tackle valves this winter, while we are butt deep in snow up here in Wisconsin.

My valve train has been really noisy since the purchase of my C. This is an awesome write up and I could not have completed the valve adjustment with out using it.
The service manual leaves a lot to be desired. From the tools required, to your recommendations and afterthoughts it really helped tremendously. I would have probably completed the teardown and then trailered her to my local stealer if now for this! I am a mechanic for the military and I wish you were writing all of or technical manuals. This is one of the most thorough and easily understood maintenance procedures I have read. Over 17 years I have read a bunch.
I recently bought a VTX and am currently waiting on a Honda service manual so I can go over my bike. After reading this I am going to go ahead and do my valve adjustment instead of waiting for the service manual. Thanks for this. As these engines wear, the valves tighten up. The detail was incredibly great! After doing it once, the second time was much easier. But the best part was the feel of the engine. The desmog and all the little changes recommended made this a great ride. Just want to give you a suggestion.
The part valve adjustment where you say to take the top radiator bolt off and shim it away 1 to 2 inches. I only followed these instructions and ended up cracking the weld on the bottom mount where the bolt is and ended up having to order a new radiator.
Name required. Mail will not be published required. Website optional. Search for:. Step 9 may seem silly or unnecessary, I mean why go back and repeat the entire process? I can only say that when I first started adjusting valves and learning the process I often found this step to be very helpful and I still do it today to check my work.
Repeating the entire process would get me up from the bike to spin the motor and when I would sit back down to re-check clearances I would usually find that they still needed slight adjustments to be spot-on in spec.
