In the description I mention this is for 2 stroke models.

@@X7rocks I know. I was asking if It was a good idea to try these same mods with a 4 stroke scooter

@yankee21320 if you're 150cc it these mods can benefit the engine specially the exhaust as they are restrictive. But you'll see more of a benefit from a larger bore in a 50cc engine, along with a variator and exhaust to try to get a little 4 stroke to be a bit more peppier than how they come stock.

@SpongeBobFunnyPants hello thanks for watching. Before the bike would only do around 41 to 43 mph. After the mods and especially after the exhaust, I was able to hit 54 mph at 10k rpms

@@X7rocks thx

@GotThrottles from initial launch to when it shifts around 50 it will go from 13200 to 12900 (less power at that rpm) it's happiest in the 13.2 to 13.5 range, highest I've seen was hitting over 70 with room to with 13,600 and climbing. Thanks for watching I'll be doing an update on another project I'll hope you'll all enjoy and continue fine tuning the zuma

@@X7rocks Looking forward to it. I have basically the same bike, Bugeye 70cc kit, Yasuni pipe, TOP variator and other components to make it work. I'm concerned the stock Yamaha crankshaft can't take those higher RPM's for long so I've added weights to limit it to 10,000 rpm during acceleration but I admit it feels like it makes more power in the 11-13k rpm range. So i either pray the crank holds, or give up and buy an aftermarket crank when it does. I will make a Dragy video with mine. How is your crank holding up?

@GotThrottles so far so good! Though there is much more power possible with the crank being swapped. I have one fun project for a drag engine being handled at the moment and will try to upload that and pick up a crank for the current engine as it should lead to good results with more air and fuel being directly funneled into the cylinder. This is the 2nd zuma engine I've had to handle over 10k rpm. Though it can last (had it last 7k miles before) and was really for it to handle the power. I do still recommend it for more higher end setups. For sports setups you're definitely good to go for a while.

@sajmirbekteshi9113 always good to get more info on it. Will have to try it out. More gy6 content will come soon Just gathering parts for 4 separate builds can cause time delays in uploads.

@tjjohnston7920 while the benefit of more case pressure being forced into the cylinder would he worthwhile. This is to see how an engine with over 7k miles can handle the cylinder and exhaust combo. A full circle crank is next along with porting the engine carter's. Which show a good result on the malaguti.

@@sajmirbekteshi9113 no big bore. Just fine tuning the stock cylinder without taking it apart.

@lizettefiguerres-dm1sn thanks for watching and thanks for the kind comment, more update is upcoming so, the goal is 10 seconds in the 1/8 mile :))

@@X7rocksare you in us sir?

@@lizettefiguerres-dm1sn yessir out in florida.

@@X7rocks i got mine to in my short vid sir

@@lizettefiguerres-dm1sn will gladly watch sir.

My power jet is disconnected. They work better with vacuum being made prior to the throttle slide. Since I used a velocity stack it wasn't having that vacuum needed to activate it. Your main throttle bog may be too small or a main jet.

Nitro 100 and aerox 100 are the dame. You'd need an mvt ignition for a 16mm flywheel shaft. Usually found for cpi engines or Chinese engines.

@@X7rocks I got it recently for 250 quid which I couldn't say no too amd I have to admit I am loving it haha so any mvt ignition 16mm will fit? I want her to be a savage! What was the difference like ie acceleration amd top speed brp?

@colerobinson2628 acceleration was nuts with the engine as it already had good torque. If I wasn't careful I could easily lift the front endnof this otherwise heavy scoog model. I liked it so much I even got a spare 16mm one for a 90cc can am engine swap for my cpi

@@X7rocks it'll fit the stock shaft amd all that shit then?

@colerobinson2628 along as it's the 16mm rotor. If not you can purchase the 16mm rotor to slide to the shaft on the flywheel side of the engine.

Charmo/ taida liquid cooled 56mm cylinder.

It can touch the bottom of the seat container, but that's the most of an issue I've had. Just need to Make sure the throttle cable as a short 90 degree fitting for the carb will fit nicely.

No possible way at all you'd be looking for one 😜

@@X7rocks Definitely not nope. Sure as hell not bringing it up to my girlfriend either 🤣

@@fthrgasp "I found this lost puppy, it will have a good home" 🤣

Thanks bud! Always glad to get more :) and future plans are going in motion aiming for 10 second 1/8 mile. And I know I can get ut.

Usually on just some trips to the gas station and to disney springs for the most convenient parking spots.

49ccscoot? I can get a hold of a front wheel for ya. I'm on Facebook as almodovar kenny

Exhaust wasn't available anymore so I did have to remove the link. Carburetor can be found on Amazon under maikuni along with a single throttle cable from nibbi.

Stage 6 sport pro variator kit. Malossi delta clutch on yellow sport springs. And malossi drive face These can be found at scootertuning.ca for your specific model. (Though if you search for polini 107mm clutch on ebay you'll find the best deal for a performance adjustable clutch for under 60 dollars I'm even gonna order a second one cause i like it so much) Exhaust is a top performance leovince zx exhaust I can't link it as they're found in europe, most likely on ebay. But you can use a yasuni z or r to get similar results. Next vid will be upgrading to a big bore kit and the results after.

Thanks!!

I'd say give it a shot :) the bonus about Chinarelli is they offer taller gearing, an since you build them with quality parts you're more than likely to have great mileage with the performance you get for them. I will be showing how mods on an air-cooled zuma like a big bore and pipe can increase overall performance and, of course, showing before and after :). Also, thanks for watching. It means a lot.

Was timing set properly for the bike?

Hello thanks for watching. But which shock are you referring to?

There's always time to get to it later. No need to rush perfection 😀

Thanks for watching! For lowend torque there are lots of great options available. Hopefully my update is soon as I am waiting for some parts to arrive from germany.

@@X7rocksnice! Can't wait to see what you're gonna get up to on this one!

Yep sure will :) with some spare room as well.

Nice!!

Thank you so much for the kind words and taking the time to watch. I find it hard to make videos so I figured I'd make a video on some modifications I feel most people can handle and still have that factory reliability. And data showing evidence of gains 😀

She's got nice sized tires that feels comfy at those speeds. And take any bumps on the road real smoothly. I'm sure I can hit mid 50s with a bit more stretch on the road but for a stock 50 cylinder she pulls nicely 😀 plus the benefit of not being stuck at 38 mph not having traffic get stuck behind me 😅 thats the worst feeling. But thanks for the comment and view it means a lot to a small player like me. When you snag a 2t bike like say a zuma. I will say riding into the 50s and even 60s feels comfortable as they have such a large tire fitment that it almost feels like a Cadillac riding down the roads at those speeds 😀

@@X7rocks i actually have a 2019 zuma that i absolutely love. and i totally get what you mean about the tires. i also feel that whole feeling bad about people getting stuck behind me at 38 (which is about when it starts pinging the rev limiter like an encyclopedia salesman knocking on your door who knows you're home even though you're hiding). and dude! you're putting out great content! it's a pleasure to watch and i'm always happy when i see you have a new vid pop up in my notifications!

@fthrgasp your compliments mean a lot. I try not to go too crazy on builds cause I like to do builds that regular people can do and benefit from and show what mods work and what doesn't work. I guess it's very basic stuff but I'm a simple kinda person 😅 though If you're in the market for another scoot. I'd highly recommend the 2008 to 2011 zuma. They have higher gearing than earlier zumas. (One negative is the throttle cam is limited) but can be modified to allow full throttle with these mods helping them out even further 😀

@@X7rocks ya know, i've seen a few of those around and thought about it, but the trick is finding one that the owner isn't really proud of ($$$), or hasn't been dropped repeatedly. but knowing the range to look for is helpful thank you! it's kinda got me thinking about things i can do to my current zuma to get a little more out of it without going wild with it. suggestions on that?

@fthrgasp if I remember the zuma 4 stroke engine can get a big bore kit and a cvt and clutch kit. But I do recall the big bore being quite pricey :( but if you can remove the limiter it should help you get to the mid 40s. With cvt upgrades I can see a few more mph as well. I've seen a few 2 stroke swapped but that is gonna be quite a time consuming project while you have a perfectly good engine to upgrade while you can. Which year is your model?

Happy new year bud!

Thanks for watching 😊 it is a Taiwanese bike called a cpi oliver city, they come with a very common/ popular minarelli style engine. Best part is these mods will fit pretty much any minarelli engine, and equivalent modifications will work very well on other scooters as well :)

Thanks for Watching and commenting. I have an update coming up of what I've done engine wise to the scooter.

Was XPRo easy to work with on the papers ? Is there a standard procedure to receive the paperwork from most companies?

Yes it was simple registration as a motorcycle in the state of florida.

Thanks your kind words mean a lot.. It's an istunt exhaust from the jungle store (amazon). It was about 168 lost souls . Sadly I'm not seeing it available on the jungle store at the moment.

@@X7rocks yeah, i'm gonna have to look for that one. and honestly, my only complaint about your videos is that they're not longer!

@fthrgasp sadly I don't know how to really pan out my times for videos. I think in my first of the series, I did manage it very well. But when it comes to videos like this, panning it out can be kinda difficult. But I'll give that a shot in the next video as I reach almost 750 miles :)

@@X7rocks yeah i totally get how trying to time videos is a pain, i've dealt with a bit of that too. and hell yeah(!!!) on 750 that's great!

@fthrgasp she's been reliable so far with the items I mentioned would increase longevity. So here's to hoping to more improvements :). I do have something special in the works and hope it can help people as well with their gy6 150 bikes.

Thanks for watching, as stated in the video this was due to a failing clutch spring and has been swapped out and did a comparison of an Amazon clutch to a polini adjustable clutch.

You can add a 63mm bore but that requires boring the cases out. Then you can add a stroker to make it to 200cc for an A case gy6. The B blocks can go up to 232cc.

@@X7rocks rolling wrench? U watch he's videos?

@Lil_eee I've seen a few of his videos. They seem to be mostly about pushing his bran. Which is fine..but I'm more on testing setups and showing results so people know what works and what doesn't.

@@X7rocks yea I hear that a lot he does give good tips tho the guy just trynna live lol

@Lil_eee exactly which is why I'm not gonna bash him for making a living and doing what he loves. Though I'd love to provide the scooter community with options. Hopefully with bolt on 180cc b block engines :) but we'll see how this can turn out if there's enough support.

I did a smaller flywheel. As for cam timing once you release the tensioner it makes it very easy to remove and install.

I am in the u.s yes. They were sold In the early 2000s. I paid 750 for it. My other scooter is a first gen 97 aprilia sr50. Only one in the u.s. I'll make a video of it soon after some updating I've been doing to it.

@robertmason8341 where in US are you located I have a 2 stroke malaguti f15 for sale in Northern California

@@user-uq4oy6go7p I’m in indiana

Best to match the jug. Factory compression isn't all that high.

@@X7rocks okay I appreciate the input. I'm glad I got someone to ask questions about stuff because I know a lot but you know I keep watching you know the videos on TH-cam and I learn even more and thank you for you know being there and answer my questions and everything I appreciate it so much. And as being a woman that loves motor cycles and love building my bike, it's hard sometimes to get some one to ask questions about things that I might not know or understand so I really appreciate again your feedback and if I have any other questions I maybe could hit you up you know so I can get the right answer and again I appreciate your input. Thank you very much have a good day

@jod5659 no problem. Always glad to help anyway I can.

@@X7rocks did you see my video that I I tried to put on TH-cam I don't know if I even got it on there I tried to put a video you know the show you my bike I really don't know how to work you know to put stuff on the TH-cam and stop my son was sleeping and I just don't know but. Oh I am very happy that you're always glad to help someone thank you very much and God bless because you know that's hard for me to to talk to people about it you know that they don't understand what I'm talking about you know LOL

It's an ncy 61mm 171cc kit. The head itself was found from gy6parts store on ebay and used a smaller combustion chamber for more compression.

Well I think I would want to get the head like he had on the in the video with the bigger ports I guess that's what he was talkin about right

Do you know maybe about what that the whole kit would cost from n c y?

None really as far as performance goes. But charging wise it doesn't give the same charge at idle as it is a smaller stator than the factory one. But while riding, the charge remains the same as stock.

It was available on Amazon but I'm not seeing it available anymore.

@@X7rockslink for the exhaust

@@mcluvin8351 it's no longer available on Amazon. Only the single outlet exhaust.
