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!
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!!!
Thanks for the comment my friend I appreciate it👍🏻 it’s those kind words that keep me going🇺🇸
This is great, as usual..thank you !!!:)
You’re very welcome thank you for watching👍🏻
Great info bro hope you and yours safe and healthy
Love you bro stay safe👍🏻
Excellent!
Thanks, much appreciated 👍
Thank you for your kind words! Ride safe🇺🇸👍🏻
Thx u for sharing
Good video thanks buddy
Thanks for the kind words and thanks for watching!👍🏻
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
Thanks for your comment my friend. I appreciate you watching ride safe.👍🏻
... Good to see you back Larry ! Is the "Tupperware easier to remove than it was on the Burg 400 ? Cheers from Brazil !
No they are still a pain to remove. Thanks for watching my friend!
The morphous is virtually identical.. the tupperware is a buy more "fun"
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.
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.
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
I wouldn’t take the chance I would order a new washer. You don’t want to have problems with your CVT.
@@ManCaveMayhem ok got it, thanks again!!!
Gonna try to do it in few days , desire my luck!. Do you know how much distance is between pins of the blocking tool ?
I don’t I just used A universal one from Amazon. I did have to modify it but it worked
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
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.
Isn’t there a contra-spring?
How you clean cvt? With what?
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
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👍🏻🇺🇸
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!!
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.
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.
It’s very likely that’s what it could be. But it’s hard for me to tell without seeing.
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.
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
Sorry sir I do not know much about the majesty 250. I wish I could be more help to you.
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.
Thanks for the info, my friend and thanks for the kind words ride safe keep the rubber side down👍🏻
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?
Not really sure. Figure 2 to 3 hours shop time plus parts.
On a Morphous it's about$200
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.
Thanks my friend for the info that does help👍🏻 ride safe my friend!
@@ManCaveMayhem awesome! You sure helped me out so wanted to return the favor.. check those air fin plates in case someone before you cracked them. Happy fathers day!! I have your videos on record... cheers!
@@vickikgibson9470 Thanks for the help👍🏻will do!
Hi, i just doing the same process, any tips for removing center nuts? Thanks
É difficile farlo su yamaha majesty 250 cilindrata anno 1996? Grazie
Well, I hope the video helped. I know that it’s not a Yamaha 250 but may be similar in some ways.👍🏻
I see you have a 2009 model. how did you reset the vbelt sign in the dashboard?
remove battery cover pull white jump plug and reset done. he put the belt on backwards, push start and watch DOR VT
Hello ManCave! My majesty pulls to the left when I’m riding slightly, what’s the best way to make a correction? Thank you
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.
Much appreciate the feedback , thank you I will check’em

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?
The rollers are supposed to be dry there coated with Teflon or nylon tight plastic is the bearings were greased.
@@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.
@@STBRetired1 I guess it wouldn’t hurt, but they are designed to run dry
How to clean throttle body
Hi. Can you give me the part number of bearings on the Secondary Fixed Sheave?
I’m sorry I don’t have that information. Not really sure what it is.
Why is the cvt drive belt grooved from both sides? Inner and outer sides?
Not sure on that it could be because it helps keep it cooler
Acts as a cooling fan as it spins. Also helps it flex.
@@billmellater Super important for belt life👍🏻
Torques are bit too low. 40 and 60 ? Where did you get them from ?
I think I got those from a shop manual. But I don’t remember now specifically. What are you finding?
@@ManCaveMayhem From Yamaha general torque specification I suggest 60 and 80.
@@sprzetmoj7579 According to workshop manual is 85 Nm for primary shaft and 60 Nm for clutch, so same as he told but different units (40 and 60 ft lbs)
@@sprzetmoj7579 but maybe do you know what about torqes in YP400RA (xmax) from 2015-2016? Should be the same because it is same engine/gearbox, but I cannot find manual anywhere…
Yea one question 🤔

Also if you could give me a list of all the domestic tools I'll need to break bike down completely🙏

How fast can this majesty 400 hit on the freeway?
My wife runs hers 75 to 80 mph when we’re on trips.
@@ManCaveMayhem good to know thanks. Do you know if all majesty scooters from 07 to 2014 are the same as far as power, mpg and top speed? What about reliability? I hear about bad throttle bodies and no start issues. Is that just certain years? If so which years are best? 2010 and up?
Not really sure on that one we bought that bike in an emergency situation in Texas and it’s been very reliable👍🏻
@@ManCaveMayhem do you think it's good to change the variator front and back where the belt rides if the face has dips in the faxes? Meaning the variator has little ridges but they are smooth.
@@damacknificent151 if they are grooved up bad then yes.
Hey question- I changed my belt today and when I took my scooter for a ride it seemed to struggle to pick up speed. Did that happen to you? Is there a break in period? I only ride w it for about two miles.
I didn’t have any problems with mine. Did you check all the rollers and everything to make sure they were in good shape? Is it a factory belt? Some aftermarket belts are really horrible.
@@ManCaveMayhem it was a factory belt and the rollers were fine. I’m going to put the old belt back on to see if there’s a difference. Thanks for responding.
@@BiggSee305 that’s not a bad idea. Also, check the face of the variator to make sure it’s clean and your clutch shoes to see if they’re worn out or the clutch drum because sometimes they get glazed over.
Good evening. What’s the make of that tool that you use to hold the variator in place?
@@BiggSee305 not really sure I just found it it’s a generic toilet was on Amazon.
Почему используешь не пятиколодочное сцепление? RU
I never researched that and the clutch that was on. It was fine so I didn’t change it.
@@ManCaveMayhem понятно, зацеп быстрее и лучше на пятиколодочном сцеплении.На это влияет площадь соприкосновения
I just use an impact and German torque spec.
That works too👍🏻

What is the meaning of I.s
I’m not sure what you are asking?
There was not enough detail explained about taking plastics off. Apparently "JIS" screws do not easily come off (not Phillips head screws).

Too much left out on reassembly as well. Need more visual detail.
You don't need to change belt until 20k miles.
Just being extra cautious
in europe they put 20.000km limit , that is actually 14.000miles. Anyhow in general the manitenance limits can be differend in EU ( more restricted ) dont know why.
I lost my belt on my morphous at 18k miles.
you missed to many steps, You should have shown the torque process.
Sorry about that🤷♂️
