I have an 09 Zuma 125 but I am about to put in a 158cc big bore and a new fuel injector. These videos you guys do are fun!
That’s one way to do a mail run 😂
Install piston into the jug and mark where the exchange , intake and exhaust ports are on the piston. Ramp the piston. Push piston to the top of its stroke and look into the exhaust. If skirt is showing, mark that so you can shave it off. Enjoy the ride. Ramping and skirting a piston will gain more power and the cost is only time.
Hi from Czech republic 👍🇨🇿🇱🇷 you Have best content 🔥
We really do appreciate hearing that man
Thank you’ll hope to get another small clip for the community me sponsored by misguided !!
Needle nose vice grips work well for me installing the wrist pin clips. Removing them as well. Also I lube everything up with 2 stroke oil when assembling.
I was like wait I think you just turn the key to open to seat 😂
Soo Brian became a delivery boy
Sending love support and respect from Boston ❤️ 🙏🏻 💪
Clock wrist pin clips at 6 or 12 o'clock. The opening that is.
12 o'clock is how my Japan assembled 04 Zuma came from factory.
RC cola spotted on the lift table at 9:58. That's the good stuff!
That’s all we stock in the vending machine
@@misguidedmotorsports When I was a child, my dad worked as a delivery driver for the Dr. Pepper plant. They did the bottling and canning RC cola along with the distribution. There were the times when they had crown caps on the 12 ounce returnable bottles. His route took him close by home during lunch on Wednesdays and I always got a freshly bottled something of my choice. They took the carbonation to the moon back in those days and it didn't matter what pop you got, you got a good eye burner from all the carbonation. The RC was my go to back then.
@@misguidedmotorsports how much did the full kit cost and where can I one mines a 100cc but I want it faster
@@r_3_d_m_u_r_d_3_r-_-25 give us a call we will run ya through some way we can speed her up 773-887-4369
The camera is getting next levelish .
10:12 Mad respect Brian! Dope video as always sirs. Need cctv cams put up sheeze.. wildass neighbors.
I ride gy6 but I still dig these bikes
you a good teacher bro !! i kinda want a zuma lol
Do it!
I got a 100cc one there hella fun
4:33 😂 too funny!!!
Looking to change my grom front sprocket ⚙️ to a 14t . Have anything in stock? New chain too
Yooo that was a malossi 70cc kit. 49 cc pistons fall threw the stud spacing and 70's don't. And I'm running an aluminum s6 "prostreet mk2? Pro something, and no not the iron streetrace kit" single ring kit and it's being going strong for around 11k miles. You just need to make sure all horizontal edges of the ports are chamferred and smooth. Don't round the ports or change a lip, you just need to take the sharpness off. Mines running strong with almost no visible scratches and you can see all the crosshatching still. These s6 cylinder kits are amazing. Titanium lined ring with nickel cyl wall. Fully recommend. I use to daily ride on the single ring
And the piston and head probably looks like that because it had a stock carb. It was burning up from not enough air flow. When u upgrade these scooters it's like when u upgrade one thing a bunch of stuff has to be upgraded if u don't want mechanical failure. I guess that's why mines running so long because I took ALL the precautions. 😂
Case induction is the way to go if you know you know
To each their own! Tbh I prefer vertical but this scooter RIPS
Is this bugeye still running strong with this set up you put on, in this video?
THAT RAP FIRE
Do you run the stock oil injection with the 70 kits?
what kinda kit you pick up
Show me some love yall !!
haha, I said all the same things the first time i pulled my bugeye apart
Yes sir!!!
What’s this Chicago scooter starter pack cost? I’ve got a bug eye zuma just like this one, need to bring it down to you guys for some TLC.
It starts around $600 and goes up from there my dude!!!
That engine saw a lot of cold starts straight to rides
Yes sir
No that engine was likely run without oil in the tank or no one bled the oil pump when the new bbk went on and seized it right away.
The piston looked over heated for sure, hope the bottom end was ok
Seemed good ran great were gonna run it!
Just send it bud!
Too much of Brian's face. LOL as an OG fan its odd to me but its what the people want!
Yeah that’s the most I’ve seen of his face
His face is public he has a mug shot for speeding lmao
Please tighten that chain a bit on the Surron just a little thanks guys ride safe
Yes sir!!!
Will do
@@misguidedmotorsports thanks guys see u next Tuesday
Mallossi 70cc kit it has the brand on the head
3 minutes into this video, and I'm wondering how this bike ended up at your shop. Never built a horizontal minarelli? Clearly brand new to this.
When you open a motorcycle shop, you are opening yourself to working on bikes that you are not familiar with. First time for a horizontal motor (openly admitted), although have dealt with many other small bore 2 strokes. However, BRAND new to the BUGEYE as well as case induction. Thank you for watching 3 minutes!
The way he was amazed that the carb fed air/fuel directly to the crank case was sad...........its like uuhhh every 2T gas engine known to man pulls the intake charge into the crankcase first lol. Then he couldn't tell that malossi 70cc bbk was a 70cc bbk...even when taking it apart.
@@chrisapolinar1102he unhooks the fuel line and says "why is this not pissing gas right now?". He works on scooters and doesn't even understand a vacuum petcock? I've found(in my four years working on mostly scoots, as opposed to three previous sixteen years working on bigger stuff) that "scooter mechanics" are often at a much lower level of mechanical knowledge and ability than automotive mechanics. I have theories on why this seems to be the case, but I don't want to write a book in the utube comments. I'm sure the video creator is probably a decent mechanic, but was just new to this specific stuff. Hopefully(for his customers)
Doesn’t know about case induction, can’t look at a cylinder and tell aftermarket from stock, and then pulls the head off and still doesn’t recognize it’s not stock right away-the oring head gasket should have gave it away, among other things and then shows the head to the camera and it clearly has MALOSSI cast right into it. 🤦♂️
I just bought a bug eye Zuma from a ginger kid and his dad. I pull up and the scoot has a big jumper pack hooked to the battery and the dad is stomping the kick starter furiously. Which confused me because i agreed to purchase the scooter in non-running condition. Maybe he thought he could get more money outta me if it started? Joke woulda been on him, I'm broke. Anyway the last kick he gives it, the kick starter stayed pointing down. He had screwed the kick start clamp bolt in the wrong direction. Anyone familiar with these knows that means it wasn't clamping anything like that. Goodbye splines right. The dad tells me his kid bought the Zuma(for way more money than I'm paying) rode it for five minutes and it died and never started again, and he thinks it just needs the electric choke. I paid the kid, brought the scoot home, and it has 60psi compression. Upon cylinder removal i find a BADLY scored 70cc cylinder and piston, with a stock 49cc head gasket hanging way into the cylinder. Wonderful, but pretty much what I expected.
PS I'm amazed how big and heavy the Zuma is. These things must be unbelievably slow stock. I've got a Vino that uses the same engine and i swear it weighs at least 100lbs less than the Zuma and it's a foot shorter. The Zuma is a tank
If someone steels your girl at the bar tha last thing you should think about Is messing with his scooter!!! Lmao first off If some dude cruises to the bar on his scooter and pulls my girl, I'm going straight home In my Duramax and coming back wit my scoot and he and I are having a fucking scoot race my guy😂😂
measure piston width that will confirm
😂😂😂😂😂 I have twenty thousand miles on an original zuma 2 smoke
That is a Case Reed engine.
It says malossi on the head😂
Can’t believe you put that piston into the cylinder with lubing it with some premix, bet you put the wrist pin bearing in dry also. You really need to do better. That old piston and rod got hot because someone ran it out of oil.
Where i can buy the part
Just give us a jingle my dude!

This looks alot like a 3kj motor
You sleep well for doing the right thing. Dude sleeps well cuz he enjoys being a bitch and abusing woman.

It forsure is man!!!
🛵🙋
Hey subscribe
The head says malossi on it ofcourse it has a 70 kit
You keep blowing topends because your not using hondabond on the base gaskets and no copper permatex on the head
No copper but yes we do hondabond base gaskets. We just log TONS of hours on them and are very hard on them!
...did he say my nuts are hanging from your head like some nunchucks???? 🤐🤐😐😐🫣🫣🤣🤣🤣🤣🤣
He said that FASHO

you americans are so weird, calling a 70cc for bigbore... lol in the rest of the world it's just 70cc...
They're 49cc stock here. So since a 70cc has a bigger bore than stock, we call it a big bore. As do the places that sell them
@@middlesiderrider the same here i eu... stil is just call 70cc
@@TEAMVISKAT81 what's kinda interesting is that my 47mm cylinder kit was sold as a "72cc big bore". But I saw some 47mm kits are sold as a 70cc. So I looked into it, and used a displacement calculator to find out the actual displacement. A Minarelli horizonal has a 39mm stroke, so with a 47mm piston it's actually only 68ccs. That sucks haha
