Your an amazing scooter geeks... i like ur experiments and explanation, im from Indonesia (where almost everyone uses a scooter)... then I am very interested in your channel... I think it will be very interesting and will be significant changes when done on a 150 cc or above. I hope you will do a new project with a larger cc scooter.
After I've been modifying these motors for years. I thought I had everything down and probably knew A to Z on every issue whatsoever. You break everything down in minute details and recording Everything taught me more then I thought. You're Awesome! Great Vids man.
I've heard of them, but don't recall seeing them for sale for the Minarelli so I don't know much about them. 122mm would be an upgrade vs stock. These days, I think it's easier just to get a whole OR kit.
@@eddietrujillo172 I'm not even sure what that has stock. For me, I'd go with sliders because they outlast rollers and sometimes outperform them. As far as weight, likely what it has is close. You can always open it up and weigh what you have and then figure out if you think it needs more or less RPM. Aluminum foil can add weight if they are too light and weights can be bored. More info here : ruclips.net/video/YkNhqEFeWVQ/видео.htmlsi=AQC4KMUz_675nm6C
I don't really really tune to any certain RPM. If I want to dial in a clutch I usually go by feel and maybe timed acceleration. If it's a stock clutch, the best is likely to be as high as you can get it to rev without the CVT beginning to shift first so you lose the low ratio for takeoff. Peak power will likely bee 9000-9500RPM with a ZX, but unless you can make RPM stay right there till max speed you'll want it to engage somewhere below that.
thx for the detailed video's ... i'm gonna try this on my suzuki street magic street scooter (morini) uses weird pulley's to ... please check out my channel i have a very fast piaggio zip sp with nitrous ... you should try to get minarelli or piaggio engines and adapt it if you wonna go faster ... here in europe there dirt cheap ... and there's alot tuning parts for it
***** if you want i can ship you a piaggio engine like my zip for free ... i have alot off spare engine cassings , i could send you some foto's and the parts for it can al be bought @ www.scooter-attack.com you only need to pay the shipping cost ( i"m from belgium )
Thank you for the offer. I'll pass for now. Just don't have spare cash and every part is expensive when it has to come from overseas as well. It's a shame the EPA hates 2Ts so much and scoots just aren't more popular here... then maybe someone in the US would stock this stuff.
***** i think there is a store in canada to called www.spmotostore.com/ that is a stage6 dealer maybe that would be cheaper for you guys over in amerika , yeah 2stroke are getting less and less over here in europe to , most new scooters now are 4stroke slow ass scoot's
Yeah, scootertuning.ca is a good Canadian store as well. It's sad. Over here I think most only think of weed wackers and chainsaws when they think of a 2T.
Old video, but anyway, you should also consider how high the 6 weights can push your pulley up(in). You can file off as much as you want, but if the weights don't push your pulley all the way in, your belt is never going to reach the end of the pulley.
You, my friend are a "Mad Scooter Scientist!!!!" I've watch many of your videos and have to say good job sir. I've been a motocross, sport bike, sports car enthusiast with a love of modifying. I've recently bought a 04 ZUMA that I'm learning about very quickly thanks to people like yourself... Thank you
I am sorry to tell you but there are 2 variations of the Piaggio Rear Pulley: The old one which measure 128mm and can be used for High end minarelli engines (which you obviously read on the net) and the newer 134mm that you used. The first are very easy to fit and work very very well. If you already figured that out and mentioned it in any of the videos I do apologize.
No worries. I knew there had to be more than one because I had heard of 128 and 134mm, but I took what I was offered at a reasonable price because I had such a hard time finding anything here in the US or fairly cheap anywhere. Thank you for the info.
Hi! Can someone give me advise? My Piaggio NRG near by 80cc (becouse i use 49mm piston) have small rear pulley 128mm original is 134mm and i'm wondering whats is benefit, with small pulley there is more acceleration from 0 and less top speed? If i put original 134mm rear pulley what will be the difference? Tnx !
The 134mm should give you better acceleration because it makes a lower "first gear" or starting ratio when paired with a suitable belt. The belt can travel just as far into the center of a larger pulley if all else is equal, so top speed shouldn't change a lot.
The other main thing is you ride this scooter back and forth long distance, i have seen those build builds and some cant be daily riders like yours and most of these guys could get you number doing the build themselves. #yournextseriescanbemybugeyezuma!! Another great video keep it up!!
In denmark you van get a used non running piaggio for around 100 USD, and the rear pulley for next to nothing used. Great video, i might try the piaggio pulley on my minarelli
Have you used cheap eBay 70cc topends for a minerelli engine? Do they do the job or are they not worth getting. I usually use pollini or malossi but I got a 1992 jog that’s was beat up I fixed it up and wanting to make it powerful enough to willie you that a cheap Chinese kit and pipe and upgrade cvt will do the job?
I think you're better off to get something better than the really cheap bottom grade stuff. Some of it is really poor quality. I've used many Taiwan made kits like Motoritech, HOCA, SSP-G and so on with good results. Of course price check stuff like the Polini Sport vs those and decide from there.
Good tips ect dude but my Yamaha zuma 1995 has got stage6 crank full malossi setup 3.6g rollers stage6 clutch overrange pully deltro 21mm carb carbon reeds quick throttle I weigh 13stone it takes off like a rocket with the front wheel off the floor & goes 74mph extremely quick. Also I’ve got a stock 50cc Malaguti Firefox f15 de-restricted by taking the thick washer out the variator & lighter rollers 4.5g polini air filter stock pipe quick throttle malossi 3g clutch & it hits 57mph. I’m getting a HMR 70 engine block for it, tbh I don’t see good power results in your Engine modifications ect
I'm 300 pounds. It makes a huge difference... put a 120lb passenger on your scoot with you and then see how quick it is compared to before. This was just my backup engine that sat on a shelf in case my 103cc wasn't running. A reliable 70cc that I would do 8-12 hour straight rides on without worry and not at all something that I was getting every last bit out of. It made a good test bed for this video series. Watch something like my 2020 Endless Summer Scootin' video to see a more recent setup.
you say that the stock variator fan usually has a lip where the drive boss meets up, mine had a washer in the lip.i drove the scooter with the washer and it had pretty good acceleration, i then removed it, i lost a little acceleration but only gained a few km/h. with the stock setup i get 81km/h, without the washer i get 83 km/h.
anubis1100 I generally find the same as you with a stock setup. More modified/powerful engines tend to benefit more from removing the spacer for speed from my experience. The washer will let the belt ride low for better takeoff, but it may limit how far the variator closes.
I used to hold them with something and then use a bench grinder. Not perfectly round, but good enough. File after to remove any sharp edges. If you have a group of them, you may be able to use a bolt, nut and washers to make a holder for them. If you can hold them tight enough, you can machine a group of them all at once. Could even put the assembly into a drill to spin them and run them against a grinder or file. Someone on the forum did it that way. I did something similar, but used the lathe to machine down a bunch at one time.
I'm not sure how that would work. If it put much tension on the belt it could change how it shifts. May take some effort to find a design that would actually work well. Seems like finding a belt best suited to the CVT would be an easier option.
i would love to see speed/acceleration difference with Hoca 54mm borekit with stocc trans and overrange trans. does it make a big speed difference and acceleration.
+tjay ismael I don't think it makes a big difference with an engine that can make more power at lower revs, but it helps some and it's a much more reliable transmission than stock or with the Hoca from my experience with them.
That member that sold the pulley was meeee 😁
was it a hp1 or a hp2 pulley?
@@regnarsk1890 it was the morini one I sent a while back to him.
@@X7rocks oh ok, i thout he bought the morini one.
@@regnarsk1890 he did. I sold it to him really cheaply since I had no use for it in my engine. But glad it went to him for good use.

手工好嘢！！！！。
Have you ever herd of the top performance rear pully for mineralli?? I think it’s 122mm not to much bigger but expensive too
I've heard of them, but don't recall seeing them for sale for the Minarelli so I don't know much about them. 122mm would be an upgrade vs stock. These days, I think it's easier just to get a whole OR kit.
Yes I agree, but they sell the top performance pully on dynoscooters.com for 80 something $$
How to get to his sight?
Why u keep adding more weight rollers on it ?? Dont it should be low weight rollers for more speed?
Roller weight needs to be whatever keeps RPM nearest peak power.
@@49ccscoot so I have a Kymco cobra racer 2t what u recommend me to get ?

Hi man. Do you have tips on how to file the shim spacers to make the diameter smaller?
I used to hold them with something and then use a bench grinder. Not perfectly round, but good enough. File after to remove any sharp edges.

Where do you buy your parts from? I'm looking for a reputable source to get jets from and whatnot!
ScooterTuning.Ca, PartsForScooters, and Treatland.tv are a few sources that I've been able to count on.
👍 👌 Excellent.
excellent video ,,,,what about making a mini belt tensioner,, on a larger belt ?
I'm not sure how that would work. If it put much tension on the belt it could change how it shifts. May take some effort to find a design that would actually work well. Seems like finding a belt best suited to the CVT would be an easier option.
Waaaaayyy too heavy rollers
try Amazon
Yow where do i buy scooter racing parts?
