I'm trying my best to be helpful and make videos that people will watch, but I will never be able to please everyone so I go with what seems to work for the most people. On the flip side, some people complain that my videos are too long when they're half as long as this one.

Amazing video. I haven't managed to get through it all YET but I can already appreciate how informative this video is as well as the amount of effort and time it took you to film and edit the whole process too. This will be my manual when i get round to doing it

[@nmemonicporsche]

Hey, I just bought a used 2012 Tmax. Actually I haven’t gotten it yet, the dealer is still prepping it, but it’s got over 30,000km with only oil changes, so I’m expecting to have to do a major maintenance like you’ve done. I love your detailed and methodical approach to servicing the vehicle. I’m finding the information you provided very useful. I can’t understand why you don’t have more “likes”. Maybe there aren’t that many Tmaxs in the US. Anyway, I just wanted to commend you on your honesty in this video. Learning from our mistakes is hard. I think what you went through will help me/us not to do the same thing. Note. The Tmax cam profile, because of the motor’s pistons both being at TDC at the same time may be a contributing factor to the difficult reassembly process. I will follow your advice if I ever have to do a valve adjustment. Fingers crossed.

[@49ccscoot]

Thank you! The TMAX was not popular in the US. They are certainly out there, but I have never seen another 500 in person. I've seen 1 or 2 530s. I think it was actually the same one twice. I saw them advertised in dealers at clearance prices at one point because the market isn't big for large "sport" scooters or scooters in general really. It's a shame, because they're great bikes. Good luck with yours!

[@KetilDuna]

Awesome video , very detailed showing all steps of installation and removal. Great Job!!

[@seamusmcshean260]

Great video. I’ve owned Two Tmax 2001 and a 2004 model. Fantastic bike, but expensive to repair if you are not mechanical minded, when they start to age with high mileage. I tried this particular job on the first one, the bike did run afterwards, but never got the tapping noice out of it. When I changed the chain tensioner on the second bike I used cable ties on the chain and had no problem with the timing. Learned a lot here, might start that job myself soon now that it has 50,000 miles on it!

[@glenstewart7910]

YOU ARE VERY HONEST MECHANIC . Even though you made a little error but you are Genius

[@Josemanc]

I feel your pain Brent. Hopefully you'll fix that changing the damaged valve and installing a new head gasket and be done with it. We all learn from our mistakes. It's good you are skilled enough to have seen the problem before engine assembly.

[@blipco5]

One other thing, after decades, I finally bought a METRIC feeler gauge set (the type that features whole millimeters instead of imperial). No need for mental conversion as the shims are sized in metric. It was the best thing I ever did in my life. Well, not really the best thing but close.

[@paulbudford]

You don't get much for $87 at the Yamaha dealer! I put the valve down to bring tired, and frustration. Like you said it's nearly impossible without some sort of locking tool, or cable ties. Still a very educational video. Which I'm sure will help others not make the same mistake.

[@mehdimed560]

Thank you for telling us your experience and for your honesty. I think this will help me a lot when I ll do it on my tmax. 👍

[@49ccscoot]

I tried it in my most recent video with the aid of cable ties and combining those with the order that worked best for me from this video made it a much easier process for me.

[@FrigolineRijeka]

Hi Brent,great video and thank you very much to show us all details.I have the same Tmax and I already done valve clearences twice.I always follow Yamaha service manual and I always put chain tensioner at the end,not like you.Its not easy because of force from lobes,but its possible.But I still dont understand a reason why this valve have problem,cant see any mistake from your side.

[@Visionery1]

6-8 thou is small, we had these settings on some of the Jaguar sixes in the 80s. Not easy to set, especially as one has to physically feel the valve lift ever so slightly off its seat when the correct clearance is reached, otherwise the engine will be noisy. Pushing in a 6-8 thou feeler gauge under these conditions is challenging.

[@pedrosanpedro5281]

If i knew half as much as you am sure i would get into twice as much trouble...nice work m8 👍😄✌

[@robertodifiorenzza4116]

Gran experiencia! Muchas gracias por tu video. La honestidad es un valor casi extinto.

[@staunch_risk_indicated4348]

Sorry Brent, I feel like I should have shared my 'trick' on Tmax forums five years ago when I did this. My method seemed risky and I had 'imposter syndrome' about it, but it worked for me. I tried the 'awl' like you did but was never satisfied with it after seeing the chain skip for myself. My approach was to torque down the exhaust cam 'cap' and cheat by using a screwdriver in the teeth of the exhaust sprocket to back-it-up so much as to actually lift cylinder 1's exhaust valve a bit to grab the chain and let the valve spring 'catch' the timing chain taut on the underside. oof. I know. If I had a trick to getting the intake cam in place from there... I dont remember at the moment... but it probably had me dipping into valve spring tension there too. I definitely remember installing chain tensioner last of all things.

[@staunch_risk_indicated4348]

47:00 I don't see this as an optional step. [measured] values of shims is what the math should be based on - screw whatever the shim print says or what the shipped invoice says. I am more likely to believe a large shim was printed with a smaller number or vice versa than you bending a valve stem. Unless you swapped camshafts and completely botched the ICE timing while hand-cranking.

[@jamest.5001]

Have you seen what goes into making quality O-rings? I'm supprised they do not cost more! With the work, and R&Dand testing, it's crazy especially when they are made from more exotic materials!! And they are made slower than I would have thought!

[@49ccscoot]

It's not something that I'm going to try to save on. I think if you are certain of what the o-ring is, and there are multiple options, and can figure out it's dimensions accurately... then you can save. However, who needs a pack of 50 fuel injector o-rings for a TMAX, and if you only use 2 you'll spend way more. It would not be worth the savings if any properties were wrong and it all goes back together and leaks. Just take my $4.XX per o-ring Yamaha.

[@DoRC]

Your compression tester immediately going down like that is not due to a bad seal between the tester and the engine. There's a leak somewhere in the compression tester hose or gauge. The compression tester should maintain pressure even if you take the gauge out of the cylinder. If it wasn't designed like this the compression tester would act as part of the volume of the cylinder and you would get lower readings then reality. Most likely there's a Schrader valve at the bottom of the hose that's leaking.

[@49ccscoot]

Thanks. I realized this after watching it back for editing. I've been spending roughly 70 hours a week on scooter work and video editing lately and it seems to affect focus a bit.

I have check scan the issue and it is telling me code 12 , crank sensor but i can't seem to find any crank sensor on this Engine. I have check all speedsensor and no issue and also no abs light on. I dont have a Dealer where i come from so, i was wondering if you have knowledge about this issue.

[@Princeofthebow]

You did a great job regardless of the outcome! Did you by any chance try to check out what the service manuals of model after your tmax say on the matter? I cannot imagine the design being immensly different and hence maybe yamaha realised and made a better detailing of the steps?

[@Night_Watch413]

In your opinion is the 09 Tmax worth it? I found one for $4500 with 7k miles, and also found a 2018 xmax with 4k miles for $4000. Which one would be the best purchase?

[@49ccscoot]

The TMAX is more powerful and probably better suited for long distance riding. The XMAX should be way easier to service. I think you can do a valve adjustment with just removing the seat instead of this huge process for example. The '09 TMAX is now 12 years old, so it may need some checks and maintenance just from age.

[@Night_Watch413]

@@49ccscoot thanks for the information, im somewhat able to do some maintenance on the tmax but the bigger things like valve checks i would bring it in to the dealership. I will be doing mostly city driving with some occasional highways

[@49ccscoot]

@@Night_Watch413 I think I'd go with the XMAX based on that info. The XMAX should be capable for occasional highway riding or even regular riding. If you want to get out on a highway and cruise 80MPH all day, then you need the TMAX IMO or some would prefer even more powerful bikes. If you want to ride around at 55-70MPH, I'd imagine the XMAX is more than capable. The TMAX is really surprising in town, so I don't think you'd have any trouble there. It weighs nearly 500lb, but it's very easy to handle. Still, you really don't need such a monster for mostly city riding. The difference in maintenance hassle may be enough to save you a lot of money by doing your own repairs on the XMAX where you may not do some tasks on the TMAX. Even if you did take it in for work, the bills for the XMAX should be considerably lower than the TMAX for some jobs because it would cost a small fortune just to have a mechanic remove the stuff to get to valves on the TMAX for example. Even CVT work has to be accompanied by removing body panels on this thing. Good luck with whatever you choose and ride safe. Lemme know what you get!

[@snuzz2177]

Hi Brent why on my rotors flywheel there is no timing mark?

[@49ccscoot]

Not sure why, but I've heard of flywheels not having any marks. Seems to be even more common with replacements. I would suggest looking at a service manual to see if they show a mark on the flywheel being used. You can make your own mark, but you have to be careful to be accurate. A degree wheel and piston stop is my preferred method. I've got some vids about TDC. kzbin.info/www/bejne/p2W7YWZjf5yGi7M kzbin.info/www/bejne/iny3f359eMqCocU

Google says the NMAX is 125-155cc. This is 500cc. I'd expect the NMAX is more similar to the SMAX here, which is 155cc. We no longer get the TMAX, but now they sell a 300cc XMAX.

[@Lord_Verminaard]

Dummy! 🤣 Just kidding. It happens to all of us. DOHC do take some getting used to, and every manufacturer does them a little different sometimes. In most cases, I almost always tie or wire the chain to the sprocket even if the instructions don't mention it because sometimes it can jump when you aren't looking at it then it will never line up right. Some Kawasaki engine manuals even tell you how many chain links there should be between each timing mark on the sprocket so if you lock it down and line it up on the crank it's golden.
