Nice spring! 🎉
Well done guys 🎉
This is such a good vid to be the first on your channel. Keep up the good videos. Insane quality and good editing. Only up from here!
Also interesting seeing a bws 100. We don’t get them in my country
Malossi n 1 !!! Italy stily!! Un saluto da milano !!!
Very nice 👌🏼
I have a stage6 sport pro mk2 top end on my motorized bicycle,lol. It’s the Yamaha prebug 72cc top end and makes a lot of power too. Great content
That must be such fun to ride!!
Firstly, the fine looking gentleman wearing a red Yamaha shirt. I see you 😍👀
Secondly, this video content was so fun and informative, as a newbie to this I love the educational bits! #malossiboys
good job!
Awesome machine
Lekker Cape Town boys, nice video i am also into two strokes just the Kymco 100CC models and my baby Yamaha TDR250
That’s awesome. Thanks for the support! We used to have a Kymco Top Boy too! Very fun scoot. Your Yamaha TDR250 is also a beaut, congrats!
We need to see a top speed run after the mods 🤙🏼
Definitely! Will keep you guys posted!
Nice video! About that broken bodypart, its an easy fix with plastic welding! Anyways video about how the variator works would be nice, ive never really understood it.
Thanks very much! The owner of this scooter has bought a brand new one along with some other exciting goodies. So look out for that in the next one! And then we definitely want to make a video explaining how a complete drive works, so thank you for the great idea!
I see a nice Italjet dragster on the background 😁 and a 180cc too
Nice spot! That one is not ours, however we do have our own italjet needing a rebuild as well as a Gilera Runner. Both 180cc.
💯💯💯
❤❤
Have the exact same bws 100
It's an awesome toy for teenagers and grown ups
I just ordered my original rollers and cant wait to install it😎👌
Edit:Can you guys give a link to the parts you guys bought?
Hey Ruwayne, they are really fun! We sell all the parts in our videos on our website! Check it out at urbanriders.odoo.com/
Any reason you kept the stock airbox and not upgrade to a pod style airfilter?
The stock airbox works perfectly fine and is better for everyday use of the scooter. A pod filter would work slightly better if you were drag or track racing. But for road use, it's less complicated if you keep the stock airbox.
What did you put on the exhaust before the silencer was added
We like to use a sealer to make sure no gases escape where they’re not supposed to.
Hi guys, I just discovered your channel, you have got some great builds!! I have an Aerox 100cc and would like to have this same exhaust mounted! Can you give a me a link to purchase it ? Yours bikely 😉😉
That’s awesome to hear! Thanks for the support! Unfortunately the CRP exhaust are no longer in production, but we hope to revive them soon!
Did you change the jetting at all?
No, completely stock carb
I notice you popped a round gaskit out of the old exhaust - did you use the old gaskit with your new exhaust?
We always install new, especially on a customers scooter. But if your'e in a pinch, I guess you could reuse the old gasket. Just make sure it is not too squashed and there is no leak after installing
@@urban_riders was the new gaskit a circle one (OEM) or did the exhaust use a diamond shaped one? I have a bws 100 too, which I've just started to mod. I've installed the technigas silent pro, which came with a diamond gaskit. I used the diamond gaskit it came with only, I didn't put in a round OEM one, so I guess what I'm really trying to find out is if that matters... Mine appears to be solid / no leaks....
@@angelaquinn8310 Yes we used the OEM round gasket and it works perfect. If yours is sealing then you need not worry. It doesn't really matte what one you use, as long as it seals good and does not leak. Happy Riding!
Where can one buy the upgraded parts?
We sell them on our website at urbanriders.odoo.com.
If you are looking for something specific, we can get that too!
i've got the same stage 6 helmet as yourself... how do you like it??
I really like the design and it’s not too bad comfort wise. Overall a nice helmet. I also have the White and Orange one but that’s old and worn out now.
where did you buy the aftermarket parts ?
We sell them on our website, and buy them direct from Malossi. urbanriders.odoo.com/
HI
I have try and do a lot of things with this engine.
Use maximum of yq50 high end parts
my setting
Carbu 28 pwk
internal rotor inition MVT custom
motor KN 9 bore alu from japan
torque drive mhr overrange alu
Clutch and torque stage 6 rt
exhaust stage 6 100cc
INTAKE MANIFOLD + SPACER STAGE6 R/T
vforce stage 6
....
Only way to have good power !
that muffler on that hydroformed pipe is going to spit goop on itself.
We only use full synthetic 2T oil in our builds so there is no oil build up in the pipe. Yamalube 2R and Motul 7200 are our prime choices.
This CRP pipe has die-pressed header sections and the rest is rolled sections. This specific method does not use hydroforming although CRP did do hydroformed versions of this pipe back in the mid 90s.
Thanks for watching.
Where did you get the veriator drive?
We sell these Malossi parts on our website. urbanriders.odoo.com
What sort of horsepower gains do you get out of doing this work
The stock power is 7.2hp and the exhaust is +3hp on it's own, so with everything It should be sitting at 12-13hp.
Where can I get the exhaust?
Unfortunately they are no longer available
Do you guys reckon with stage one I need to upgrade clutch springs?
The clutch springs will only change the RPM that the clutch engages at. Heavier springs will allow the motor to rev up higher before engaging the clutch. So it depends on how you want the scooter to launch off the line.
If you want a drag race pull off, go with the stronger race springs. I suggest testing your setup first and decide from there. Hope this helps you, and let us know how it worked out.
@@urban_riders alrighty thanks heaps
Ended up replacing stock variator with this malossi kit and installing a technigas silent exhaust on it as I didn’t want too much noise. I’m getting about 82km/h (up from 80kms) and weigh 75kgs. Would you suggest I take it in to have it looked at?
@@taylordickson4089 If you are using the 11gr rollers that came with the Multivar, combined with the Technigas, you will need to go lighter on the rollers. I suggest around 7gr. This will allow the rpm to be higher into the exhausts 'power band' and give you quicker acceleration and better topend compared to the 11gr.
@@urban_riders absolute champion. I appreciate that and will order them now.
How Big is the Piston , on a 100cc BWS
The standard piston is a 52mm
The standard piston is a 52mm
What weight rollers are you guys running .
We running 7.2gr on the Multivar for this setup, mainly because of the exhaust.
@@urban_riders ordered 👌 lol
@@urban_riders Hi guys ! If i Only install an exhaust, should i also use smaller weights than the stock ones? The same weight 7.2gr? And also you should make a video testing differents weights top speed so we can check the real diference between using 7.2gr - 8gr - 9gr for example. And finally the video everyone is looking for, is how to install a tachometer in the BWS. With a tachometer you can check how high in rpm you are going to see if you want to push it further or not. Have a great day, loved your video
@@onitutu Thank you for your feedback and tips. Depending on the make of performance exhaust, you would run 6-6.5gr rollers on the stock variator. We will be making more content on your suggestions, in the future. With regards to roller weights, we have pretty much figured out what works with what. This could be a video to do?! Thanks
May I ask want a performance exhaust 👊🏻🐦🐦
Unfortunately we have stopped production of our exhausts until we can setup our new fabrication workshop.
What country are you in, maybe have a look at the Technigas?
Hi mate I'm UK can U help me out with a Speedo cable for my Yamaha bws100 I'm in UK
@@DalesmithSmith Hi Dale, The part number is 4VP-H3550-02 and you should be able to order it via your local Yamaha dealer. They can special order it for you. Send us an email and I'll forward you the parts manual. We can't export unfortunately.
Sorry to bother you, but a that exhaust is not going to add 3hp on a stock cilinder. (dont know if the cilinder is stock)
Hi Sido. We've road dyno tested this exhaust and the increase was 3.1hp on the stock motor and drive, with just lighter rollers. We've been part of the development since the 90s on this. In conjunction with all the Malossi mods, we've managed 16hp already.
@@urban_riders how i put a 117c airsal and also full malossi how hp u think u would get
@@leno3733 The Airsal is a few horsepower less, but not a bad kit. The Malossi tends to have better porting and better designed while the Airsal is based off of the stock with stock porting. Not sure the exact horsepower difference.
Capetown Boyz,?🎉
Yessir!
