Yamaha Majesty 400 CVT Belt Replacement

This is a simple how to video that will show you the procedure for replacing the V belt (otherwise know as the CVT belt) on a Yamaha Majesty YP 400 YG this covers the years from 2005 through 2014. The model year I'll be working on is a 2009. If you haven't yet hit that like button, subscribe and share, it really helps me out and don't forget, "I'm just a MAN in a CAVE causing MAYHEM!" Thanks for Watching!

I've only had one of my bikes worked on by someone other than me. It was a recall situation. Never even got a state inspection as required here in PA. I'm about to do this on my morphous and I'm sure I could have done this without this video, but doing something a second time always goes smoother. I feel like I've done it once by watching this. Possibly cut my time in half. 👍🏻 Great video, well done mancave!!!

[@ManCaveMayhem]

Thanks for the comment my friend I appreciate it👍🏻 it’s those kind words that keep me going🇺🇸

[@vickikgibson9470]

Oh, one more tip. Check that fan plate!! Some people use the tork wrench to put the main nuts on and it way over tightens the nuts! This causes stress cracks on the fan plate. It us NOT meant to be more than the the 40ftlb setting. These stress cracks can make the disk break apart when driving higher speed and it gets hot. Mine was riddled wirh tgise cracks and I had to replace it. It was so hard to get that nut off. Set waaaay to tight! Just an extra thing I found when rebuilding mine...thanks to your great video!!:) I thought I saw cracks on yours...u might want to recheck on both bikes...:) anything for safety!

[@ManCaveMayhem]

No they are still a pain to remove. Thanks for watching my friend!

[@papaballoon]

The morphous is virtually identical.. the tupperware is a buy more "fun"

[@thedaydreamer7972]

Good job, I just moved a majesty 400 motor into my Morphous, its nearly a direct engine bolt on with a few things to move/modify, its so important to take care of the transmission,,,,Also if you put in Dr Pulley sliders, it not only will wake up your bike, but it will decrease crusing RPMs as well, if you notice the belt wear mark line on your variator, there is still a few more MMs for the belt to travel before it reaches the edge, the sliders will give you more travel, speed and top end, it essentially puts your bike in the power band once you find the right weight,,,, but really the majesty is a great fast scooter,,,TY for the video

[@ManCaveMayhem]

Thanks for your comment my friend. I appreciate you watching ride safe.👍🏻

[@vickikgibson9470]

Ok. I have 2 tips about the aluminum cover. When you remove the small screw, Remove the CENTER NUTS! It takes the pressure off the seals. Also there are release slots along the cover to try and gently pry it loose. They are in-between the small nuts in a few spots. You won't need the mallet. I got thexremival info from a mechanic in Europe. The cover just about falls off when you remove those nuts! Like who knew?? :) hope this helps for future fixes. Cheers buddy. Oh,put cover on,then tork nuts.

[@ManCaveMayhem]

I don’t I just used A universal one from Amazon. I did have to modify it but it worked

[@mrpantur7280]

not a bad video. I was very impressed that you actually didn't use the impact to tighten the variator or clutch bolts back up. a lot of bad mechanics do this because there lazy and you can damage the threads on the crankshaft. it happened to me lol. not very fun and now I don't trust mechanics lol. i would add that you should of mentioned checking the variator surfaces for wear and the importance of it for example if the variator is worn and there's flat spots on the edges it can affect acceleration and also lower the bikes top speed.

[@ManCaveMayhem]

Thanks for the info, my friend and thanks for the kind words ride safe keep the rubber side down👍🏻

[@Johnboy062086]

Do you have a video of you taking the plastics off of this majesty? I bought one and the floorboards and plastics are all in pieces. I need to know what the tear down and rebuild order is. He was replacing the fuel pump. I’m not sure if I have all the correct screws and fasteners or not.

[@ManCaveMayhem]

I don’t. I took it apart once when I first purchased it. I would recommend going online for a shop manual. Sometimes you can download them for free.

[@rhoa]

I have a 2005 and it started to vibrate as it starts to accelerate. Do you think if it the clutch or the Dr Pulley rollers that needed to be replaced. Thanks again

[@ManCaveMayhem]

Just check them both. Once you’ve torn into it that far it’s easy to look at both. Depending on what rollers you have you’ll see flat spots or the clutch will have signs of wear similar to brakes. Hope this helps👍🏻🇺🇸

[@adamoliphant2754]

Great Video! I am thinking about buying a 400 Majesty from 2013. Would you recommend one over something like a Vstorm650? I personally enjoy riding my 150cc chinese scooter more than my Suzuki GS500

[@ManCaveMayhem]

It’s a very nice scooter. My wife loves it and I’ve ridden it quite a bit. We are actually planning on selling it if you’re interested, hit me up.

[@natenj]

Hey ManCave, I have a Yamaha Morphous 250, I noticed that it has the same covers underneath like yours. Well, I was running mine seemed like transmission wasn't "shifting" and then heard a snap. Could it have been the belt that snapped? Is that common? Mine has 18k miles. Just traded it and don't know previous history.

[@ManCaveMayhem]

It’s very likely that’s what it could be. But it’s hard for me to tell without seeing.

[@billmellater]

Same thing just happened to me at the same mileage on my morphous on the highway. Pretty uneventful, just a snap, motor responding to throttle but no excelleration. My immediate thought was drive belt. Not that I'm a genius mechanic or anything but watching the belt drive warning flash for a few thousand miles was my first (and last) clue.

[@crimo100]

Hi sir, and thank you for the great video, i have a question, i replaced my clutch but i am pretty sure i did not put the washer and i cannot find it anymore, what could go wrong if i ride it without the washer? Thank you again

[@ManCaveMayhem]

I wouldn’t take the chance I would order a new washer. You don’t want to have problems with your CVT.

[@crimo100]

@@ManCaveMayhem ok got it, thanks again!!!

[@vickikgibson9470]

Hey buddy! so i bought the 400 like yours, same year. It seems to have a LOT of vibration ,so at 10 thousand k would that mean a bad belt and variater rollers? I don't dare take it uo faster than 25 klm...it just feels very rough. I know it needs air filters but that should not create such vibration. Any tips for replacement stuff. I would install the 5 pad clutch as I hear the 3 pad obe is very rough vibration. Also what about the rollers? Sone say replace with higher grade 15grm, or the 18 grm origional, and others the italian grade( Molasi ?) ones...but I dont know weight. I am giving it new oil,spark etc. Most people ride until it fusses then and sell. Anyway, thanks so much! It's a challenge to learn to ride as you feet go much further out! But made it out on my first little ride and did not fall over. Yeah!:) Cheers!!

[@ManCaveMayhem]

I’m still running the stock equipment I just changed the belt after 14,000 miles the engine does run a little rough which is typical for a single cylinder, but the rollers and variator were all good when I checked them. Only way to really tell if they’re bad is to tear into it and check everything if you have flat spots on the rollers then you know they’re bad but if you don’t they’re probably still good.

[@erikdiamond]

I am debating on Burgman 400 v.s. Majesty 400. Which one is easier to maintain yourself? It looks like a lot of screws to disconnect many things just to replace the belt. What is the ballpark estimate if you have someone at dealership/service to replace belt?

[@ManCaveMayhem]

Not really sure. Figure 2 to 3 hours shop time plus parts.

[@papaballoon]

On a Morphous it's about$200

[@frankanekeh3705]

Hello friend. Please I have an issue with my 250 Majesty. Did some work near the injector since then the green transmission light has been blinking on 1-S. And the gear is stock on 1st gear. We have a Yamaha dealer around here. I guess it needs to reset to get the transmission back to normal. Please can you help me

It’s hard for me to tell if I’m not with the bike. But if I was to make a guess it could possibly be tires or head bearings check the front and make sure everything’s in tact make sure your suspensions good etc.

Seems like some stuff missing such as there is no lube on the bearings (rollers). Just metal on metal??? And what kind of lube did you use on the variator bearing? What about the clutch assembly - there are moving parts in there so don't moving parts need lubrication of some sort? And, finally, I see some magic marker marks on the clutch assembly. What were they for?

[@ManCaveMayhem]

The rollers are supposed to be dry there coated with Teflon or nylon tight plastic is the bearings were greased.

[@STBRetired1]

@@ManCaveMayhem You had me up to the word Teflon then my old brain dropped out or something. So, the rollers are supposed to be dry. They are coated with Teflon. What did you mean by "or nylon tight plastic" and "is the bearings were greased"?

@@STBRetired1 I’m talking about the rollers in the variator. They are like mini skateboard wheels that roll with the centrifugal force of the engine.

@@ManCaveMayhem In another YT video, the guy sprayed his new rollers/sliders with Blaster Dry Lube. I looked up about Blaster Dry Lube and it didn't seem to stick particularly well. But Blaster does make a Dry Graphite that requires a lot of work to get off. I wrote to that fellow about the graphite and wondered if it might be a better dry lube but he never answered.
