I ordered a cp21 but looks like mij throtte cable doesnt has the necessary throw to open it fully. Do you ever had this problem and how do you fix that? Thanks in advance.
Pro tip, get a fork from a yamaha slider or a yamaha "rocket" or called "zuma" in the US i think. Not the inverted fork. The 12 inch 5 spoke alu wheels are the best for these scooters. Pirelli sl26 tires are the best i've used too, you can run them bald like slick tires and they still grip. I had over 40000 km (24850 miles) on a stock cylinder and carb, airbox, only changed exhaust to a bidalot s2 (equivalent to a MHR exhaust). Clutch springs to yellow mhr and push spring to yellow i think also, and variator weights. 3x3.6grams and 3 stock rollers. Could only do 43-46mph but it was quick at picking up that speed. Ps: For this exact model. With a lot of wheelies and hard "drop downs from wheelies" the welding on the frame that holds the front fork get weakened. You might to keep an eye on those, if you see your front wheel/tire getting closer and closer to the front fender plastic, then you might want to check the frame welds. PPs: The front plastic cover can "often" break around the screw in points when doing wheelies. Might want to strengthen those points, fill the surroundings of it with hotglue around the screw in stem part of the front cover. I really miss riding my scooter, it's been over 10 years now. Cool vid, brings back good memories. I have an old bad video from me doing wheelies on a channel called "TeamPropuls" and the video is named "Les débuts en lève". If you ever watch it, i am the second rider in the video.
The Canadian version is the same as the dutch version by what i can see. Bws is what I know the original version. Here in Holland they where never that popular because it's a vertical engine instead of the horizontal one that we all used and use for racing
@@MOPBOYZ i just imagined it might mess with the ignition timing with the cylinder being further away from the engine block, resulting in a higher rpm and lower efficiency.
maybe if you ran like a quarter inch of sealant hahah . you only need a little bit my dude. and that could never change the rpm. only thing that could change is the compression if the head was further from piston on the stroke
I know! i had one in all black but the rear plastics on mine ware thicker it didnt have that stepdown from the seat and had a rear spoiler bws bump [still miss that thing but traded it for an Piaggio NRG back then] nice find bro
@@88brderpi20 my friend has a mallosi vl16 or sum when he got it it had a limiter whcih made the hole smaller we put it in it rode ok, after taking out the limiter the whole was alot bigger and it rode so much better
@@88brderpi20 we must not be talking about the same thing cuz in our country when everyone buys them we always throw them out cuz if u put it in it rides exactly like stock and the hole is the same size as stock if u take it out it makes it bigger, and its probably not for all intakes maybe not the one he used in the vid
@@imdovis787 then you buying either some cheap reedvalves but its not a limiter the hole has nothing to do on power... stock reed compared to vforces and the power is same.
Hey bro I have a 2000 Aprilia SR-50 with a 70cc Malossi MHR Rep kit and carb. I installed it years ago. Then never finished it that I would sell for a good price to you. I live in Reno NV
Great score... What are your thoughts on a Yamaha cr50z target?... Was thinking about swapping my razz engine out.. have a chance to pick up a cr50z engine... I hear they are pretty fast stock
Nice find. Looks like a 95. Here in quebec canada sold the 89-90 as the zuma. Cuz of high demand in europe, mbk couldnt provide any models to canada, as well as the states. They came back to canada in 95, under the bws name. That ones looks like a 95, could be 96…Think they came back to the states in 97, but under the zuma name…
got that backwards pistonnnnn boiiiiii
makes the scooter ride backwards
Old man mop here. Still learning from u. What a find. Can't wait to c it pop up. Mop on u the man
I got a bws bump which is basically prebug with different fairings and it's made in france
My german Booster has got the US type lights with a grey footroom and a black heatset. In Germany the MBK Booster and Yamaha Bw´s are exactly the same
Man that beetle in the background is beautiful man !
In lithuania we put yamaha aerox wheel and forks,brakes it upgrades looks and breaking performance by a lot.
Stock cranks are 100% fine to run with a mild 70cc street build 👍👍
true can run up to 13.000rpm a street 70 polini kit will run it fine
yea, ive always wanted a Zuma/Mbk Booster, but they dont make them in my country. cool video though keep it up
12:00 What do you call this pressure meter? I want to buy one :)
Definitely saw a puch maxi engine
I ordered a cp21 but looks like mij throtte cable doesnt has the necessary throw to open it fully. Do you ever had this problem and how do you fix that? Thanks in advance.
im about to buy one also from the garage, it was sitting there for like 20 years. Can you please tell me how much u spend for this build
yo g my 89 prebug havin an issue where all the lights arent working would u happen to know what it is??
What ratio do you mix your fuel when you're breaking in a brand new engine all aluminum high performance with high performance crank please
32:1 always
Cant wait to see that e50 build!

4180kms is 2597 miles.
In Canada they also have the BWS R.

sealant on cylinder kit? i’ve never seen that before in eu, just the provided gaskets.
always sealant everywhere 💪🏼

@@MOPBOYZ ah ig u right. watching your videos made me wanna buy a bws
Copper spray a gasket is the best stuff, clean to does not bleed over when torqued. Great score man keep um comin.
where can i find parts that ship world wide i wanna rebuild a sym 50cc scooter
I think MBK was sold in france, but it is the exact same thing as yamaha
Mbk were licensed to build yamaha bikes dude. Had a mbk nitro 100 (aerox 100). They where produced in France.
I had one 25 years ago and i loved it
I know! i had one in all black but the rear plastics on mine ware thicker it didnt have that stepdown from the seat and had a rear spoiler bws bump [still miss that thing but traded it for an Piaggio NRG back then] nice find bro
what do u think about peugeot trekker 100
Can you please make a video showing all the parts you use in your naked bars on Zumas. Love your videos.❤
i’ve showed it in a the build videos of both the scooters that have it on bros!
Yes I know, but can you show where you order all the items
11:20 if thats not stock reeds theres usually a limiter which u can take out which makes the hole really big, the limiter makes it like stock
Its not a limiter its a guide for the gas and air.

Gray footboard n cover 🔥 what a coincidence gray frame sliders and dude bro hooked you up on the parts with the bike💯💪🏾

BWS Bump was my 1st moped ever
In Portugal we got no zumas, no prebugs, no nothing. Only BWSs, and they are so good

Hey bro I have a 2000 Aprilia SR-50 with a 70cc Malossi MHR Rep kit and carb. I installed it years ago. Then never finished it that I would sell for a good price to you. I live in Reno NV
hey man! DM me on @MOPBOYZ on instagram !
Great score... What are your thoughts on a Yamaha cr50z target?... Was thinking about swapping my razz engine out.. have a chance to pick up a cr50z engine... I hear they are pretty fast stock
We call it a Billy whiz in the uk because its fast
but here in belgium stock stickers are a hard find
Man that thing is sweet
Ha ha I got an aerox come in with same problem, piston backwards 😂😂 awesome work on the channel but can you do an aerox 100cc air cooled??
Maybe we could discuss all your surplus parts😅😊😊😊
Nice find!
replaced pannel. on speedometer should be red also

THE MASTER. IM NOT WORTHY. OLD MAN MOP. CRAZY DOG

Y buy the carb when u have a new one with the parts u got given
cause that carb is too small
honestly no sealant is necessary all piaggio and minarellis lc and ac I have done never used any extra sealant and never had a problem
Rj needs to cash you out on one of them Yamaha’s if he hasn’t already 😅
Why run the cp21 instead of the dellorto karb the dellorto is way better quality
cause it’s a 17mm
yessir!
A Canadian eh?🤓
Nice
Im fast af
But a bws stent Really rare
true bws werent in america so yes its rare here, we only had them sold under
"zuma"
Arrow is backwards
bro buy a old shape typhoon!!!!
mbk boosters are better
Rare? You got one for free and I had like 4 in the past. And now somebody wants to trade my piaggio tph for a bws XD
you’re probably not in america then as they’re very rare in america cause bws wasn’t in this country
Pronounced: beewees/biziz up to you..
