- 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
Immaculate intro 👏
Haha thanks bro!
Cool video, I'm going to look for #2.
Now you will want upgrade carb and gears
looking forward to the build I got the same scooter
Yes me too! Just got around to getting the Cvt dialed! Next video should be out in the next week or 2!!
Thanks for watching Kyle!!
@@MintWorxTv sounds good I just ordered a polini complete cvt kit for mine. engine parts later on
Jesus is king!!
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
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?\
@@welcometomyjourney3982 best way is to reference what the cylinder head on your scoot looks like compared to the stock head
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
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
@@joeblow8206they do not do 47 mph stock
never had an issue with the oil injection just make sure to bleed it.
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??
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
Don’t need to delete oil injection just top off each tank with a cap of oil especially extra when first install kit
Yes also another option!
@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)
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.
the oil added to the fuel can make your petcock leak so a manual pet should be used ..
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
Yeah, two restrictors. That is correct.
What about the yasuni c16
@@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.
@@OGSirSmokezAlot that doesnt have any restrictions
What about the giannelli reverse
i got simmular motor on my malaguti crosser cr1 i got a 70ccm malossi kit for it malossi fly clutch i keept the clutch spring stock i am running 3x4.5g and 3x7g rollers in the malossi multivar my top speed was 80km/h
can you give me links to the parts that you listed?
Yes! All the parts are listed under my build page at www.mintworxmx.com There is also a link on the video description! Hope this helps! Thanks
Whats cool about a stuffed piston
My bike does 40 on flats and it’s all stock
05 zuma 50cc 2stroke
That’s pretty good! How heavy are you!?
@@MintWorxTv 250
That's the bad thing about cast cylinders, I always went with aluminum "athena" I ran the str8 Bar swap its way better
Good to know!
donde consigo el escape yasuni ?
🔥
One bolt and engine comes out of bike. Instruction say cylinder and rings should be assembled dry.
i have same scooter 08 2 stroke 10k miles 36mph 43 down hill stock
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…
Where you learn how to do all this seems like a smart kid
Lots of messing up haha
@@MintWorxTv great video, I have a 2014 zuma and I'm so stupid when it comes to this. I wish you were in michigan so I could learn lol. Live that you live Jesus. Loved your video brother!!!
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...
Fun stuff man!
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?
You can buy a new pump or if you want to pre-mix the gas there is a way to delete the oil pump
Its going to Blow up because of the double gasket
What double gasket are you referring to
Check out scooter swap shops video on derestricting pipes
Increase the pump delivery instead of deleting it
What slider weight would you recommend I have a 2016 zuma 50
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!

If those metal reeds fail, you will destroy your engine
Iv never heard of metal reeds failing. Have you?
@@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
Nice shirt love it Jody Holcomb Hillsboro Ohio I kinda gave up on Jesus but I said to my self he did not give up on me so don't give up he is love.can u send me a free shirt like yours XXL Hillsboro Ohio. Nice I got 2 scooters thanks for let me no I need parts
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?
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.

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
@@MintWorxTv
Thank you as well.
And I wish I still had it because it was a whole lot of fun
