Don't buy a used motorbike if you haven't watched this video. A big surprise in this review. #nmax

You are on the channel where you learn how to mechanic a scooter at 101 clicks I'm Marcelo Garcia and I'm going to show you this 2020 N-MAX that arrived here at the owner's house who spent R$ 8,000 on it and made this mess that I'm going to show you Guys, this is a 2020 N-MAX, the latest version of the first generation model It's very beautiful, all personalized, you can see this sticker, this name on the side It's very beautiful, but I'm going to show you how it arrived This scooter arrived for me, it came with a jack, look how it is It came here with the CVT part disassembled, all inside a box I see that the secondary shaft retainer is missing, it is without the filter Here is the primary pulley, well worn and locked because probably the roller came out of place And look, here's the surprise, it came with the reducer box open, without the screws This must be in the box that came with it And here on this side, look, the owner said he had the engine repaired Spent R$ 8,000, I didn't believe it, and he sent me the service order, and he really spent R$ 8,000 He says he didn't tighten the screws on the reducer box, and the oil leaked And with that, he destroyed the gears and the transmission bearings Look how it came, the caliper here hung, came without the caliper screws, I didn't find it The exhaust came out, here is the completely damaged thread that holds the exhaust People, look at what people do Except for the other absurd things, the screws that are not from here, here too, these screws are not from here All inverted, missing part, missing screw Look at the screws on the side where it was to stop, down here Interesting that people put wooden screws here The thread is not even compatible, people put it there Look at the screw up here, this one goes here All inverted So this is going to be a surprise box Time to disassemble everything, because it's not working, it doesn't work at all Let's see what's going to happen So I invite you to follow this challenge of repairing this Max pump That must be a mess in there, let's leave it new again And count on your like and come with me I'm going to do the disassembly here so we can have access to the gearbox And also see the possible damage it has I can already see that the disc is super worn I don't know if the owner will want to change it right away But the main focus is to fix the gearbox and make this engine work Because it's not working People, the gears came out here Look at the amount of metal that is deposited here in the gears It melted and broke the bearings So it was turning metal with metal in there It ended up spoiling So let's do the disassembly of this part and open it to see how it is Here is the gearbox, open Look at the state of this bearing I don't know if the camera gets it Look, it's all broken Broken gear A worrying thing with the bearing housing of the engine housing It's damaged Let's clean it up and see it in more detail All bearings damaged Look, it even got dark, so much temperature To work without oil Only one guide pin came Only one, the other is missing And here is the set of gears They work here like this And this big one goes here This whole set is compromised It will have to be replaced So we already have the bearings disassembled We removed part of the engine from the housing And here from the housing, part of the cover Luckily, the bearing housing did not deteriorate much It's in good condition And here we have the gear Here are the green bearings, the shaft The whole set has to be replaced People, look at this bearing Look how it got, the cover burst Look at that And the spheres got stuck in the gears Look what happened to them It stopped being a sphere Look, it's broken So the rest of the material of the sphere It's stuck here in the middle of the gear Can you see it? Is it right? So all this has to be replaced Buy a missing guide pin And do the assembly of the new bearings Then do the proper closing Put the correct oil, the gasket The hose here in the place of the nozzle It goes here in the air filter box And here is a brief cleaning of the engine Can you see how dark it was? So let's provide the parts And we'll be right back We finished here the assembly of the gearbox Here are the gears We assembled it without any noise All the new parts Here on this side The assembly has no secret Just fit the gears, the new bearings It's all here The CVT was also assembled here All reviewed Now let's disassemble it completely Do a general review The owner said he had some problems Let's see what's going on Besides having assembled everything wrong Here, people, the exhaust It's sunk inside It took a fall So much so that it bent Even the support Of Garupa's little foot Inside, I don't know if you can see Where it is screwed It's inside So let's try to pull it out Because if it doesn't fit, the radiator cover The protection In addition, follow the disassembly Now that we have completed the assembly CVT and transmission Let's do a complete disassembly To see what's under here Stay in the video Let's start disassembling Everything is inverted I've already shown it in several videos People are there Disassembled Look, I had to stop the video To disassemble here Something that made me angry Because you can't believe That they do this I'll show you here And poor thing Who buys a motorcycle like this It doesn't need to be for sale Look at this Let's start with the basics This motorcycle already had a fuel pump It has a new auxiliary But the pump is not working I don't know why Let's check Look at this motorcycle It's starting to break This white here Out of place It's in here Another thing Cylinder retainer leaking They put a wire To pull the burr You can't burr anything From the chassis to the bottom Because it isolates by the grease That's one thing Another serious thing This motorcycle had a side crash That's why the exhaust is like that The pedal is almost touching the radiator Because This wire That goes to the back Doesn't support the pedal It's inside So much so that it bent Here it's straight And here It made a burr And it bent inside That's why it's not hitting So guys The chassis is crooked The motorcycle bent a little Another detail The engine is out of place Everything is in place It's not that bad But With the help of action The motorcycle is in this state There is no bolt in place Here the nut That holds the suspension They didn't put an easy nut With this cap Here the exhaust is all sunk You can see It's all inside It was the side crash And here it doesn't fit the radiator The mark I don't know if it hit It's on the pedal It's bent So that's it Worry about the situation of the NMAX Used Who will buy You don't see these things When you take it apart Unfortunately That's how most Scooters are I don't know why They welded A pin Crossing the handlebar And the bolt came out Here the part of the weld That they did It must be because they bent The handlebar And put a soldered pin That's it Now wait for the fuel pump To arrive And continue the assembly Buy the screws And it will look like this Here I would have to pull the chassis But I don't have the tools It even bent This iron Complicated Let's go Another thing The engine support And it's crooked This part The engine And here is the rubber Look at the result Looking from behind Look at the wheel In relation to the mud This bike that you look from behind It's in the middle of the side And it's very crooked Let's do the general cleaning Let's see what the owner will decide Here are the parts Let's do the cleaning Now that it's clean It's even better to see the details Look at the chassis Shining But it's crooked Here is the tank part Here is the auxiliary rail of the pump When the pump is replaced They put the auxiliary rail Here is the front part And here is the part that I showed It's crooked Here And this iron Let's see what we're going to do Make it work And reassemble in the conditions Guys, whenever you're going to weld Don't forget to turn off the battery If you hit the weld With the battery in place The battery explodes I'm going to remove the rust And so it was the weld Now just do the sanding And do the paint To not rust And also correct what was crooked Now let's redo the thread To be perfect It's new Now let's take this screw We put it just to guide It was well centralized It was good Let's just redo the thread Let's do it from bottom to top It didn't even shrink much Just to clean And let's test Of course, let's put a new screw This is just for heating Perfect There's already a way to fix the fairing here Just paint to not rust And it's ready I started it It worked There's a problem It doesn't work Let's change the fuel pump It's very messed up What happens It worked now I did the complete chassis cleaning The radiator water level was very low I re-welded the support I put the nut too We did all the threads It's cool Now it worked It's normal But it's making a lot of noise Listen We'll have to take the tank out To change the pump And adjust the valve You'll see how hard it is We already assembled a lot Look at the front New screws The welds you saw me doing Now let's adjust the valve You'll see how hard it is To adjust the valve For both versions It's the same procedure Follow me To adjust the valve You have to remove the cap From the head To have access You have to remove the tank The fuel tank To have access You have to remove the VVA valve To have access To the valves And also the synchronization point You'll see how hard it is To synchronize I turn the pulley To tighten I know when it's time to compress That it moves The valves You can see You have to align The mark on the pulley More or less here Here for the intake valve The measure is 0.10 I already loosened the adjustment screws Now I'll put the blade in the middle And adjust The blade has to pass Between The pin and the valve Without getting stuck And without getting loose Like scraping It's stuck I have to loosen a little But it's ideal I press against the pin And it's ok I'll do this on all four I did the valve adjustment It's absurd The valve is totally stuck The exhaust This engine suffered serious failures Because look at the mark The engine was made The owner spent About 8 thousand reais In a famous shop In São Paulo And they didn't change It's probably There's a strong mark here It must have hit the chain And hit the valve cap Look at the gap It's making a noise They should have changed this part They didn't change it They probably asked for it And didn't change it Now I'll do the assembly This is a very laborious job It requires patience You have to disassemble everything And then you lose the gasket You lose some things I'll have to position it right The gasket so I can fit The valve cap The head So there's no leak A detail I noticed And a serious mistake This shop that made the engine For the owner Asked for a fortune And I can see here That the cylinder base gasket You can see it green It used a parallel paper gasket It can't be It has to be an aluminum gasket It's a metal gasket Original I noticed inside the engine Aluminum mesh The oil circulation Must have been obstructed By the paper gasket It clogs a channel In the cylinder base It damages lubrication I'll leave it registered So he can see That it was assembled with a parallel piece And the original gasket I've installed the valve cap I've connected everything Now let's put the tank in place Let's see the difference With the regular valve The first start After everything is installed It doesn't hit anything The tank fell Perfect Guys, it almost reveals The shop that did the maintenance It had an oil seal It was kept here Specialized shop To make a mess like this That's it It's good Well guys, a well done service It's something else Now I'm going to put the new shock absorber It just arrived And I have to assemble the fairing I've installed the new shock absorber It's from FAR, Raffaella It's an Argentinian shock absorber It's very good The cost-benefit R$250,00, R$230,00 It's worth it Guys, the bike is so crooked Look at the wheel Because of the crooked chassis The shock absorber is on the side It almost doesn't fit I've shown that the chassis is crooked This bar is inside It's bent here and bent in front You saw what I showed in the video Well guys, that's it I've finished the mechanical part Now I just have to assemble Install the shock absorber And a very cool fairing I'll show you First The valve is stuck It doesn't hit anything Nice And that's it The general review You saw the disassembly The transmission The general disassembly The cleaning The adjustment The valve adjustment And I installed the shock absorber It's very cool You'll see now It's very beautiful It took a lot of work But it's worth it The front is very cool Thai style Very cool Let's see how it works First Look at the front I'll adjust the height of the headlight It's very cool, smooth The button is down here Let's turn it on and off Down here I hope you enjoyed the video Subscribe to the
