Watch This BEFORE You Mod Your Scooter | Yamaha Zuma Build 1

Well that didn't go as expected...
While doing any major upgrades to your two stroke, it always a good idea to delete or loop the oil pump and run premix.
Next week, you will (hopefully) see this beast cruising down the road!
As always, thanks for the support and watching my videos! I am very appreciative.

Just got the same bike. Looking to upgrade it also Thanks for the video

[@Nicholas42069]

It blew up because your cylinder at head were leaking. Do not oil the o ring on the head. Use Honda bond on cylinder gasket and on head(very important)it will always leak if you don’t . Torque head to 12 ft lbs before and when cylinder gets hot(important). Oil injection is adequate for 70cc kit

[@welcometomyjourney3982]

How can u tell easily if it has the 70cc kit I have a 05 Yw50t i got off a guy. hAs leo vince uprgraded pipe and rollers haven't torn into it as it still runs like a champ. but would like to know more if it was converted or not. It does keep pulling past 40 a long way on gps speedo and the actually speedo. It feels quick. But the build up of speed takes a little bit till the bike is hot and begins idling on the pipe any advice?\

[@Nicholas42069]

@@welcometomyjourney3982 best way is to reference what the cylinder head on your scoot looks like compared to the stock head

[@scootchie]

Don’t need to delete oil injection just top off each tank with a cap of oil especially extra when first install kit

[@MintWorxTv]

Yes also another option!

[@bobloblaw204]

@Scootchie - OMG thank you for the tip. I have a Pollini 70cc kit that I want to install this spring. Thought I wasted my money as pre-mixing is not a route I want to go. 06 BWs50 (edit: yes i know this technique is still kind of pre-mixing, but not deleting things is good)

[@MrSpaz12]

Believe it or not, that can actually make it run even leaner. Makes no sense I know, but Google it. Just a bit more is okay but as you add oil you have less fuel but the same amount of air. You're also adding carbon which will build up and score the cylinder. I prefer to just run a good synthetic castor at the specified ratio or when keeping the stock pump a good synthetic designed for auto mixing. It's thinner then the oil you mix yourself. 2 strokes are so finicky but once you get em right, nothing beats em.

[@jasonretamar2849]

the oil added to the fuel can make your petcock leak so a manual pet should be used ..

[@EricEidenberger]

never had an issue with the oil injection just make sure to bleed it.

[@Rellowoods32788]

Love my zuma just wondering do y’all premix oil in the gas tank since it’s a two stroke?? Because I haven’t been and it seems like it’s starting to bog down a little bit when I’m riding sometimes??

[@r_3_d_m_u_r_d_3_r-_-25]

I used too pre mix in fuel tank but was told by mechanic to use the original method which was the bottle under the seat the cap next to the fuel cap

[@predator_boiz336]

There should’ve been a restrictor in the silencer as well , 2 stroke scooter pipes have 2 restrictions to remove to get full use of the pipe

[@EinarLerschen]

Yeah, two restrictors. That is correct.

[@OGSirSmokezAlot]

What about the yasuni c16

[@EinarLerschen]

@@OGSirSmokezAlot c16 city has them but not sure about og c16. It's not a road suitable pipe even on paper so I'd guess it is not restricted.

[@marcojobse7407]

​@@OGSirSmokezAlot that doesnt have any restrictions

[@bitzadani868]

What about the giannelli reverse

[@infacix]

i have an 02 zuma with the stock top end, some cvt work and a custom pipe like the yasuni you picked up. it hits 48mph on flat roads against the wind. im 160 lbs and everything else on it is bone stock

[@joeblow8206]

47mph is stock top speed so not too much dif. Maybe take off if you did clutch rollers and springs with pipe. Add 5mph top end with my secret if you ask nice

[@jaronson199]

What double gasket are you referring to

[@MrSpaz12]

SLOW STROKES 👎🏼 Love the shirt btw. Got my '05 to 75mph and probably could have gotten 80 if I re-geared it. But life happens and I parted it out and now all these Zuma videos are popping up in my feed, making me want to do it all over again...

Mine cut out today after few bumps on road and it wont fire back up usually starts straight away even from cold anyone got any tips wants to start but doesnt fire up

My guess is that something got lose like a spark plug cap or something…

[@welcometomyjourney3982]

i have the same model. So it has a leo vince zx pipe but the mix pump is still on itbad does it have to be to weld the piston to the cylinder?

[@dick-parker]

You can buy a new pump or if you want to pre-mix the gas there is a way to delete the oil pump

[@1ghh]

donde consigo el escape yasuni ? 🔥

[@AndrewSmith-eq8np]

Increase the pump delivery instead of deleting it

What slider weight would you recommend I have a 2016 zuma 50

[@MintWorxTv]

Hey Hunter! That’s something you have to tune for. If you buy the multivar variator it comes with rollers. I would recommend buying a kit off Scooter Tuning CA that has a variety of rollers so you can maximize the variator. A good way to test if you’re using the variator to its max potential is to draw a vertical sharpie line on the inside pulley surface (where the belt rides on) and then run the scooter wide open and see how much of the line is worn off. You can adjust your weight from there! If the line is still there you can put lighter rollers in. Hope this helps. Reach out with any further questions! -Nik

If those metal reeds fail, you will destroy your engine

[@MintWorxTv]

Iv never heard of metal reeds failing. Have you?

[@submergedroots]

@@MintWorxTv They definitely can. There were a few members on Zumaforums when it was active that had theirs fail. Running these engines at the higher RPMs that BBKs can hit puts extra stress on the reeds

I am a little confused I have a 08 bws and first day I got it going 65 Kmh on a perfectly flat road and it had a 50cc Engine with just a big mane jet in the carburetor?

[@MrSpaz12]

You should have been fine with the stock oil pump. I ran a mallosi MHR 70 with the stock pump. Jetting was most likely the problem. You didn't show it but I'd be willing to bet that you can hone that cylinder and get a B or C sized piston and it'll run again just fine. My first MHR I didn't set the wrist pin clip correctly, it came out and the cylinder looked destroyed. I held onto it for a year and one day decided to try to fix it. Used pool acid to get the aluminum from the piston off the nickasil and a few hours with some Emory cloth smoothing out the gouge from the clip. I never tried running it myself but I sent it to my buddy in Japan and he slapped it on his scoot and it ran just fine. He ran for more than a year. Anyway, that was nickasil, which is nowhere near as forgiving as the cast iron cylinder you have so I'm certain that you can repair your cylinder. Also, tuning weights... They're your best friend. Hell, after I used them to tune my scooter the first time, I never used anything else. If you look for my name on 49ccscoot.com you'll see some of my builds and see that I'm not bs ing you. Even a few vids on this channel with some of my zumas. kzbin.info/www/bejne/e3_ciZZ7jMqgZ80

[@MintWorxTv]

Hey man! Thank you for all the info on your build! And yes I can still hone that cylinder out and use it again and probably be just fine. I didn’t even think about that before I ordered the new one. Now I have an extra haha. Also that scooter in your video hauls ass! I’m impressed haha
