wow, never heard of fixing a new part!! That sucks!! I have a 99 pre bug in boxes that I just got titled and I am fixing it up to make it work really well. Thanks for all your information and help I found most of the big ticket items already so far so good. Its a solid bike over all!! Thanks-W
Full support from Italy 🇮🇹. In my city is full of "booster". Keep up with your content man. Happy to see an european culture across the ocean. Anyway i have a Piaggio Nrg Power 😊
@@dufr9503 Nope. It's the mc4 technically ☺️ Google it and you see the difference. Same engine of the nrg mc3 but with different chassis and different bodywork. On my RUclips Channel you find a video of my NRG Power. Go to see It 👍🏻
Back in my early days of moped / scooter tuning 2001, if ever the gasket broke on a 70cc we did a quick fix cuting it out of a soda or bear can, here in EU Denmark 💪
I have the exact same type of zuma. I just unseized the engine on it, and now it needs the fuel line unclogged and the CVT tuned up. It hasnt ran for 13 years, and I just got it to fire up for 10 seconds at a time. But then it dies (I'm spraying gas into the carb). The electric starter is completely dead, and I'm missing the Kickstarter pedal. so I use a high power drill to start it.
Can you please link the homemade leak down test parts and supplies been trying to find them for a few weeks now struggling to build my own cylinder leak check device , or please make a video thanks !
Where is your workshop I would like to go one day! I love your videos even though I don't understand English at all hahaha greetings I live in DC and I'm from Venezuela
I have to buy the 89-01 zuma 70cc big bore for my 1983 Yamaha jog with the vertical 50. But not building it until I get all the life out of the original engine.
You put the washer back on the front cvt pulley under the nut? Leaving it off ads 5mph top speed also leave stock but variator side. Blue springs? Hmm. Whats wrong with a leo vince zx exhaust? Unbaffled muffler and bored out header side it works just fine. thermometer? On a 2stroke? Ad a 4 coil longer strut off another scooter to accommodate the taller rear rim/tire setup another 5mph top end. Right carb. Wrong head. 70cc kit 68mph, 200lb rider when I'm done
@@nico-broo it's an air cooled 2stroke. We beat those too hell at high temps. Add a little oil to the gas tank on top of what the oil tank puts in. Just a little too much is bad. Dif temp spark plug from stock, can vary, and no worries
These are the scooters as we know them in Europe, they cannot be compared with, for example, a Honda Camino from the past. The MBK (same as Yamaha) as in the video actually only has advantages, because of the thick wheels, good handling, but also because there are a lot of parts available for it. I also had an MBK 20 years ago and enjoyed it immensely. In combination with a Polini 65cc kit and a Gianelli exhaust. An adapted vario and that's all it had to be. Currently, scooters are rarely sold, the market has shifted in this area. You should look for Metrakit, Polini, Malossi, Airsal, Hebo, Fabrizi, Pro Race, Bidalot, Yasuni, etc. I replaced all this with a KTM SX125. But, scooters are and remain fun, you can work with them endlessly and adjust them and strive for a different result each time. Cheers.
yea i have c16 on a few of my bikes, i like them for top speed. this is not my bike and the customer doesn’t want to pay for a pipe, if it was mine i’d run a yasuni r cause i like bottom end pipes more
@@MOPBOYZ yeahhh i ride low rpm bikes but the stage 6 cilinder is a high rpm one,if you put a low rpm pipe you lose all youre power , low rpm cilinders is yasuni r /high rpm cilinders are c16 or 21
Hey brother. I found a 2000 Derbi Predator 50 with 1149 original miles. I got it from the 80 year old guy who bought it new in Chicago. He rode it on and off from 2000-2002. Been in a climate controlled garage since then. Title and all manuals came with it. It's put up. Mint condition. It's for sale.
I have a small scooter like this but is a yamaha target 50cc and I will put a 86cc top performances with the small wheels 😅 And I have another one target 50cc I will put a 100cc 2fast with the wheels in 12 inches 😊
I want one of these things i wish i had the cash u have to buy one every other week lol jk but yeah love these Zuma's .. pre bugs right ? Is what they are called . But they are so damn expensive in ny area im sure they are sny where else u go too . Its just crazy that they are so pricey
before you drive on it, why do you not put the cylinder shields on, the piston is gonna lose so much compression if it gets warm and you don't got the shields on and then you can just replace the piston
you let it run for a few min no shrouds to do a break in you want the bike hitting 200 then shut off and cool down and repeat. you check for leaks, and you can’t check for leaks with shrouds, you don’t ride it like that no shrouds lol.
I just left my theft recovery roughouse at the tow yard, spray painted missing plastic panels, burnt up cylinder from not premixing no plates poped ignition, my mint custom scoot turned into meth wheels😢
@@MOPBOYZ I have a kx112 I'm building just got a lighting coil I'm gonna try to make work, but the roughhouse was my delivery vehicle money maker just bummed about it big time
Why do people want non bugeyes over the bugeyes? Can someone please give me pros/cons, I’m looking at a 2008 Zuma that has 6500 miles on it or a 2007 that has 1600 miles and a 70cc kit
Always a good day when you post
🫶🏻🫶🏻
1:30 that noise is mad satisfying when the bearing slots in
Nice! My scoots are going into storage for winter soon; Hoping to get a little more nice weather before then; At least I can watch your videos!

@@bandeano3870 yeah. Crazy... It's Crazy to think my NRG Power turns 20 years this year. Is a 2004, One of the First NRG Power ever produced
Bro buys a new zuma every week😂😂😂😂

@@MOPBOYZ nah unfortunately 😂
@@MOPBOYZ pre bug or bug eye?
prebug
@@MOPBOYZ I got a 1987 Honda aero 50 that’s not running with new carb and new head gaskets and seals

always a W, would love to see a mbk booster spirit like mine 🤘
Thank you for the all the information in your videos it helps a lot :)
yessir glad it helps 🤘🏼🤙🏼
I just had a stage 6 intake with a bad casting in the same spot, SSS took care of it luckily.
a lot of flaws lately on these scooter parts sadly
Have you heard of Inner Rotor ignitions before? Malossi, Italkit, Polini and Stage6 have made one
I bought a pre bug for 40 bucks can’t get it to start has compression spark and clean carb any ideas on what to try
you sure it’s getting fuel?

Cool to see her coming back , one question why is it common to delete the starter on this bikes and also have seen it on elite and dios ?
the starter gear adds about 30g rotation weight on the crank. also the starters junk out a lot with high compression builds
@@MOPBOYZ ohhh thanks didn't knew
Hello can you please explain anulate the electric starter plug, in europe the ground cable its the yellow and green.
Definitely need goober weld for kickstand! Good stuff.
Thanks for mentioning that thermometer!
perfect timingggg
Is there a running in period or can you whack it from day one?
LOVE
Yoo bro get the paggio ciao, that was so fun light bike and if you gonna tuning this its gonna be crazy
Ive been building scoots a long time and yet have i owned a pre bug. They are unicorns in texas
Ayeeee good lookss you put it in a new video so I ain’t half to go back to the bed from Canadia bet
Yeah buddy need to get a video of you and the boys ripping get go pros on each of them
youtube will love that forsure
@@MOPBOYZ but it may just be fun
Where is your workshop I would like to go one day! I love your videos even though I don't understand English at all hahaha greetings I live in DC and I'm from Venezuela
It's in his garage
What is a good 70cc setup for a af18 engine? At the moment im riding with a malossi 70cc sport cilinder
finally a new video👍🏻
I have to buy the 89-01 zuma 70cc big bore for my 1983 Yamaha jog with the vertical 50. But not building it until I get all the life out of the original engine.
Mannn where do you find all these low prised zumas????
this one was at the junkyard / auction yard lol
How much $ for the big bore and everything u need to do tbis
link in description to scooterswapshop if you want to check prices
Got a peuegot speedfight 2 100cc 2 stroke project I got from an old farmer. No idea if it runs its just sat in my shed lol
Worth to repair! Those 100cc engines are quite quick and fun to ride.
@@rv9990 didn't know that haha I'll have to dig it out in winter and have a play. I don't have a key or anything.

what happend to the puch maxi ?!
parts take forever to ship for that thing , all from overseas 🤦🏼♂️
Bro you have to buy a full malossi kit of you swap the motor whit let’s say an aerox you can build it whit a testarossa cylinder
try to build a gilera stalker its proberly the wildest thing you can build but i think you need to imort it
Did you put the 7g weight straight from the top performance kit in the bike ?
yea but it’s too heavy for my liking. i’ll be changing it
@@MOPBOYZ yeah figured you’d run 5.5-6.0s
The bearings don’t need grease?
the bearings are oiled by the 2stroke oil mixed with your gas
@@MOPBOYZ Okay thank you.
Anyone you know have experience with the pm tuning 70cc kit?
Way to go.
I can't believe how big them cases are compared to theses like two stroke bike engines

What the budget for a build like this? Or a ballpark cost?
1500-2000
Get a yasuni c16 exhaust you wil notice mutch more power because of the high rpm cilinder and a low rpm 50cc leovince zx

Bro how can i order this to in India
How to tune the Cab, Have watched dozens of VEDIOS on RUclips and makes me even more confused.
Finally!
I'd buy one off yah
DO YOU SELL ONE BOOSTER?
You should build a 125 cc Zuma to 170cc Zuma! Maybe even TwinTurbo’s’s!😂

Nice
mk2 sport pro would really show its potential with c16, r1200 mxs exhaust
Zuma? I had one of them but mine was called a yamaha BW'S
you’re probably not in america
You need Buy a Peugeot ludix or import one its the best wheelie moped you can get
if you pay shipping
Bro pulls out the steel hammer after he nicely put’s in the bearing😂
just some love taps make sure she’s seated
Why do people want non bugeyes over the bugeyes? Can someone please give me pros/cons, I’m looking at a 2008 Zuma that has 6500 miles on it or a 2007 that has 1600 miles and a 70cc kit
They are lighter
Junkyard zuma ain’t so junky no more🫡🔥💪🏼
