- Welcome to Scooter Street! In this detailed guide, we'll help you uncover the best scooter engine for tuning. Whether you're a beginner looking to start tuning your scooter or a seasoned rider in search of a new project bike, choosing the right engine is crucial for achieving your desired performance.
Different scooter models have varying engine characteristics and capabilities, resulting in significant differences in power output. For example, while one scooter may have a maximum power of 7 horsepower, another might have 70 horsepower. These differences can greatly impact your tuning experience.
When it comes to scooter tuning, two factors play a vital role: engine characteristics and the availability of performance parts. Engine characteristics determine how well your scooter responds to performance tuning, while the availability of performance parts ensures that you have options to modify and enhance your engine.
We'll delve into the four major engine types commonly found in scooters: Honda engine, Minarelli engine, Morini engine, and Piaggio Hiper 2 engine. Each engine type has its unique characteristics and variations, making it essential to understand their strengths and tuning potential.
The Honda engine, known for its reliability and longevity, is available in vertical and horizontal models. It's a great choice for mild engine tuning, offering a range of options for achieving a street setup with 7 to 10 horsepower.
The Minarelli engine, synonymous with Yamaha scooters, comes in both vertical and horizontal variations. It is highly regarded for its tuning capabilities, particularly in the liquid cooled variant, which is one of the best 50cc two-stroke engines ever made.
The Morini engine, commonly used by manufacturers like TGB, Pegasus, and Suzuki, is known for its moderate to high-end tuning ability. However, it is important to note that the Morini engine is prone to left-hand crank bearing failures in some iterations.
Finally, we have the Piaggio Hiper 2 engine, which is our personal favourite. It can be found in various Piaggio-associated brands like Aprilia, Derby, and Vespa. This engine stands out due to its newer design, extensive parts availability, and the ability to convert between air-cooled and liquid-cooled variations.
Throughout the video, we'll explore these engines in detail, discussing their pros and cons, tuning potential, and available performance parts. By the end, you'll have a clear understanding of the best scooter engine for your tuning needs.

I'm just getting into scooter maintenance and tuning, and this channel is _unbelievably_ valuable. Great information, but most critically, great communication. One thing I would comment is that the addition of some sort of visual aids (footage, images, or animation etc) concurrent with the speaking would really help with making the information points/video intuitively engaging (and probably consequently pull more views too). It'll be a cost-benefit evaluation to figure out how far you'd want to go with that though, as I imagine it'll take more time. There might be a sweet-spot of effort-to-reward in there somewhere.
Thank you for your great comments. we honestly struggle to find time to present these videos, but appreciate your views, cheers.
Hyper 2 is definitely my favourite out of them all! Very good engine and so so many tuning capabilities 😁
3 years ago I decided to stop taking my yamaha aerox to the mechanic shop...I took the time to watch a lot of videos, on carb tuning, engine rebuilding, top end and bottom end and I have never looked back. saved so much money and eventually got to the point of redoing my crank bearings, seals, piston, gaskets etc. I will say, minarellis are easy to work with in my opinion, once you know what your doing. only thing I don't do is my electrical system/brakes as I have no experience or trust myself with doing my brakes.
Well done👏. We agree easy to work on and if you have a go at the brakes and elec. system you will find that you are capable of repairs and upgrades, self educate and give it a go👍
Excellent video very well spoken and laid out. Thank you sir
Thank you!
You definitely answered what I needed to know vary well thank you
Glad it was helpful! Thanks for watching🙌
Brilliant video. Explained very well. Thoroughly enjoyed it. 👍🇬🇧
Wasn't sure how this would go down but wanted to give a vlog type delivery, thank you glad you liked it.👍

Hi what would you recommend to get my sons 50 jog rr 2008 lc going better . Not wanting to 70cc it yet.
It's piped and that's it.
Thinking of taking washer out of variator and 68 main jet.
If you think this isn't much good can you recommend some thing better please. Thankyou Simon uk
Way to go guys.. Great info
Bomb it up thanks mate..💣
Good vid mate 👍
Was a little nervous as so much info to get through, Thank you😁
Hi bud I have 2020 genuine roughhouse sport 50cc 2stroke all stock, can you recommend what to upgrade on it Is still pull hard even had the restriction on variator when I open the cvt .
Get the most powerful cylinder kit that is suitable. Is Roughhouse a PGO? Match it with exhaust and transmission parts and don't forget the carby👍👍
Love your work lads! Only shop on the coast for this type of stuff! What’s the thoughts on a Sym Jolie? Love them as it was my first bike but not sure how how well they build
Love it, they are extremely responsive to tuning and perf parts. Running the Vertical Honda engine. One of the small frame scooters, solid and heaps of fun.
@@scooterstreetau and does this apply to the Sym Jet X by chance aswell?
@@cameronpriddis602 If you apply the same parts and effort to both, the Jolie will win due to power to weight.
Hey great video. I have a sym dd50. What parts would you recommend, in order to get a bit more out of it. Cheers!
Thank you. These little scooter have great potential. I would go all out, cylinder, carby, transmission and gear kit. Similar to the Honda Vertical engine, same engine parts.
@@scooterstreetau think it's very similar to a honda dio. Thanks will start saving!
What spark plug u recommend on Gilera Runner 70cc. Malossi MHR cylinder, Stage 6 MK2 crankshaft, Dellorto 17.5. Double red sponge. Airbox with 18mm holes.
Main jet is now 80, needle is full down. Im still dealing with sputtering low speed... On this setup, NGK BR9 seems a bit hot BR10 cold on full throttle...
Change the needle and oilot jet at minimum.
For sparkplug, See the Malossi recommendations. We use BR9ES in SR50R.

You don't have a Gilera Runners in Australia?
Here in Europe are very popular
Thank you. We have the 180cc GR and the VX and VXR 4T, but not the 50cc.
In Croatia Runner is a "holy grail", most popular is old two stroke Runner 180sp, but is very rare in good condition, it's like a unicorn 😄
Hey man i have a Zuma prebug 2001 and have upgraded crack with stage 6 bbk sport pro with c16 what's a better setup that keeps the power but not so rev hungry . Want lower end power sooner the c16 wants 7k+ before power kicks in and stays happy at 12k Any suggestions?
Go for a lower end exhaust, C16 requires high RPM.
A yasuni R would work great lower down. It would give you over 1hp more up to 7,000rpm and still make reasonable power.
I have the Hiper 1 LC engine on my 99 Zip Sp1 and it is bulletproof the only issue with that engine is the water pump, the crankshaft can stand some sport cylinders, i have on it a stage6 Streetrace 70cc with the stock crank with 17000 Km and a C16 its doing about 11hp
Very nice! Move to the external water pump system.
Got a question which motor is used in a Peugeot Jetforce or Speedfight? Does Peugeot develop their own engines?
Peugeot have their own 2 stroke engine.
What about malaguti f12 and yamaha jog rr are they good for tuning?
They are perfect for tuning.
Hi I have a 50 mL TNT Roma I think it’s euro five what do I need to do to get max horsepower out of it
The late model 4 strokes EFI are very diificult/expensive as they are controlled by an ECU, the ECU holds the limit to the power, replace this and then you can upgrade the engine and reap the rewards. Until the ECU is unlocked or replaced most mods will be unrewarding.
God Job 👍
Thank you 🙌🙌
What engine does a Honda dio have ? An is it a good engine to mod
It is a Honda design engine AF18, Vertical orientation, excellent base and capable of high tuning upgrades with terrific performance.
What about the tomos a55 motor? Are they good
What is the a55?
Hey there Scooter Street, was just wondering if there is a derestricted cdi for a SYM Jet euroX 50cc?
Jet EuroX is the same engine as Jet BasiX, I was not aware they had a restricted CDI.
@scooterstreetau ohh so they come with a derestricted cdi stock??
@@deezy128 I do not know for sure, but I do know this. I have never built an upgraded one that has hit the limiter, so I have not required it at this stage. Most of these also require a gear kit to get and high speed action.
I have a 2022 Kymco Super 8 50cc 2-stroke
Looking to make it as fast as possible with the $500 I have for now ?
Do you have upgrades in stoke at the the shop in bundle?
Thanks
You may need to spend more than $500 to get it rocketing but a good place to start would be the 70cc kit.
@@scooterstreetau thank you do you have any in stock at the bundle shop or any exhaust pipes ?

Thanks for a great video. Finding out more about my kymco and as a honda lover I'm happy to have a strong reliable engine and with a 70cc kit I'd be happy if I get 10hp.
Thanks for watching 🙌. What Kymco do you have?

Just the video i was looking for. Thanks man.
Edit: wow you're a wealth of knowledge 👌
Quick question, thoughts on peugeot speedfight 2-4?
The three and four are nowhere near the same build quality of the earlier versions. I guess that's what happens when you move production to China. 🙀
The earlier immobiliser issues are legendary. But there are bypass kits.
Not so many tuning parts available for any version now.
@paulbudford pretty much summed it up, the early production was high class.
Thanks for the props😁
Hi, we’re you planning to do a video of the stepped stator key?
We can add it to the request list👍
@@scooterstreetau cheers
Was going to buy a mojito 50 2T for local GC work commute no highways mostly coastal rds along beachfront etc mainly for fun save fuel and ez parking compared to car …in my case is it worth tuning a 50cc or should I wait for say a mojito custom 125cc …also dont have motorcycle license
The 50cc Mojito is such a cool scooter. My choice is the 2T. These are very hard to find and are a classic model.
@@scooterstreetau cheers for reply 2T 50 it is …will bring to you guys for service and tuning advice

Cool video sr50r 2011 carb the best scooter for tuning I am doing one up ..uk
Share the results on Insta. Whats the @?
Nice video!! I have a stock 2001 aprilia sr50 what racing parts do you recommend? Thanks in advance
Polini variator kit. Tighter clutch springs, adjustable polini clutch. Upjet the carb to an 87 jet. Malossi cdi. Malossi kevlar belt. Leo vince tt exhaust or yasuni exhaust. Should see around 50 to 55mph. Won't get much more than that. Unless you go big bore kit, aftermarket crankshaft. Also get a malossi sponge air filter that goes in the stock airbox. Avoid open air filters.
IS that Morini Ditech? Or Minarelli?
Same as the italjet dragster 50cc engine👍
@@scooterstreetau I'm not 100% sure I believe it's a ditech. It's direct injection and the engine has no kick-start. Don't know if that helps
@@JDMz thank you for your help also if you know any legit online store to purchase this parts I would appreciate it.
My all time fav to tune is a piaggio 50cc zip 2t or similar engine👍
Yes agree✌, Easy to tune, parts are cheap and the results are fantatsic, a small wheel base to lift the front wheel.
Hi Master. help me. I have a piaggio zip one 1993 2t 50cc dellorto 17. The carburetor has 50 jets ;( what would you recommend? For full power. Malossi variator, Laser xpro muffler
The 70cc kit is the best option for power. Is this an option?
@@scooterstreetau I'm considering 70cc. But first I want to see how much I can get out of the 50cc.
Thinking about DR Evolution 70cc, Top Performances Black and Malossi Sport 70cc
@@majkelzuki1774 The approach you are taking will give you a greater understanding of the parts and tuning and this make will make a great preparation for when you decide to upgrade the cylinder👍
@@scooterstreetau Ok :) Thank you very much💪
I have a piaggio zip base ac after 1999 and It had a weird vibration to it, I don’t know what it could be it would vibrate on idle and on certain rpms and would kinda wave in and out of vibrations the max speed was still 60kmh without derestricting it any ideas ?
Check the flywheel. also check any rotating parts that may be out of center or off balance, include bearings.
@@scooterstreetau alright I have a suspicion it might be some main bearing and seal problem as it seems to have a air leak from somewhere maybe that
@@scooterstreetau also you guys life savers for almost all scooter engines this channel really is gold even for just watching vids for entertainment
@@LauLauisnotreal Thank you so much🙌
Hello sir,
What could be causing some popping and bogging at 2/3 - 3/4 throttle on a 150cc GY6 scooter? Can you think of anything electrical that can be.causing this? I've already installed 3 new carburetors, 3 different csi boxes, different coil wires, and a couple other things and I can't seem to get rid of it. Would a bad stator or rectifier be the cause? What about a bad vacuum fuel pump? I just don't know where else to look. Can you help me please? I am really just so frustrated right now.
Thanks so much for any advice you could offer.
Could be: Weak spark, CDI or Stator not burning the fuel and this gives a rich engine. 2nd thing to check, the auto choke on the carby and make sure the jet is not rich. When this happens it is usually caused by a rich system. The rich system can be from over fuelling or under sparking, usually the latter and I would change the stator.
@@scooterstreetau hmmm, I think you may be on to something! That's the only thing I haven't changed in the entire trike. I've changed carburetors, jets, coil, cdi, rectifier, and just about the entire engine. I haven't changed the stator though... The plug is black when I clean it and test drive it and when I give it 3/4 to full throttle it starts to pop and cut out. I thought maybe the jet was too big so I went to a 100 and it did the same thing but the plug didn't turn black so I put the stock jet back in. I will try changing the stator. I truly appreciate your help my friend! I'll let you know what happens.
@@mikecuev820 All the best.
@@scooterstreetau one last question sir, can I use a 6 pole stator when my engine has an 8 pole stator in it? I was just wondering because I have a new 6 pole in the parts room. It's a 150cc GY6
@@mikecuev820 HI Mike, we run the channel from support by our curious viewers. www.paypal.com/paypalme/scooterstreetau

Hello, if i put malossi sport 70cc and want to run premix, how many ml oil per gas liter should i put? And if i choose to keep the oil pump. How much should i adjust it ?
Start at 30:1 and adjust if required. If you keep oil pump we leave it at the current setting if testing is suitable.
@@scooterstreetau How do i know if the setting is suitbale? I don t want to risk the piston
@@Octavian17 The plug will foul if too rich, if too lean the piston will lack oil and risk overheating. Tune the main jet and carby!!
@@scooterstreetau i will tune the main jet and the carb but my problem is only the oil pump because i don’t know how much i should adjust it. I think i will just disconnect it but i don t know what i need to remove
@@scooterstreetau btw by 30:1 you mean 30ml per gas liter?
And what about 125cc scooters. Which brand is the best for tuning there?
We like the Honda and Yamaha, there are so many parts available..
Hi dude what’s a few cool 2 Stoke scooter makes and models?
Watch the video, it is all about the best 50cc to tune👍
If I’m not mistaken aprilia never made a euro 5 sr50 r, I got the euro 4 2020 and as far as I know there aren’t any newer ones.
You are correct, we may not see a new model again. No more Zips either. Piaggio/Aprilia only advertise SRGT in a 125cc. Piaggio Liberty 50cc and Vespa Sprint 50.😲
@@scooterstreetau 😢
How to adjust air mixture screw for the coorect mixture on aprilia sr 50r E4
Should be set from factory, 1 full turns out from full closed position. Plus or minus .5
Do you know by any chance why my scooter only starts if i give gas when cold? when it warmed up it starts ok, but if i let it sit like 5 10 minutes then i need to give gas again to be able to start it or else it would start and die
Could be many things. Has anyone made any changes or modifications to the engine? Check the rubbers and manifold. Check the air filter to intake and pay attention to the auto choke or change it manual. Check the piston and rings. Is the scooter regularly maintained? try a new plug.
@@scooterstreetau i had tried a ngk br9es but my spark plug was black so i changed to the original one and now it is a coffee brown colour, everything is as it is supposed to be. I don’t know about the auto choke but i saw that the scooter doesn’t have a clamp where the air filter is going to the carburetor.
@@Octavian17 Fix that.
I'd say the 5su/5bm yamaha jog 2t and the gilera runner 180 2t.
Superb Scooters.
I have a 2005 Gilera Runner LC DD hiper 2 pro and I think this is the best engine to tune 🔥👍 back in 06-07 I made the fastest and strongest scooter ind Denmark 🔥 it was a Yamaha Jog FS Minarelli LC Malossi Team Speed ll 74,5cc it made 26,64hk and a top speed of 178 km/h this winter I will start tuning my Gilera Runner and see how much power I can pull out of it 🙂 my goal is to get 30 hk out of it but let's see 🔥🔥
What an amazing project, the Gilera will impress. Keep us up to date with the fitout, all the beast🙌🙌
@scooterstreetau i definitely will keep u updated 🙂👍 I was thinking about making UA-cam videos about the project 🔥
i had a Gilera GSM 50 standard moto morini geared engine i believe not AM6 ......i swear that thing would do 50mph out of the box !!!
@martinparker9249 u can not compare the AM6 to a scooter engine.. yea the AM6 engine is the best 50cc engine ever build but compare it to a completely different style of engine is not fair 🙂
Minarelli and Morini (and Peugeot) engines are way easier to convert to LC than Piaggios btw.. In Piaggios you need to split the engine, in Minarelli you simply put on the water pump parts instead of the fan. I found it kind of strange that it's mentioned how easy it is in the Piaggio (where it actually is the "hardest" to convert and do maintainence on compared to the other engines out there).
One big part difference that devides the CPI engine from the Minarellis is the Gearbox. It's basically a completely different construction back there. A Minarelli Wheel will also not fit on a CPI engine. Other than that, the CVT case on the CPI engines is like the Minarelli short (which was ignored in this video, but that's okay, the short minarellis are quite rare). Overrange Kits will only fit with modifications to the CVT case. You can fit a minarelli Crank with bearings in the CPI case if you want to. But actually some do the opposite today since parts are available and a bigger spline means more strength. Not that I've seen a spline fail other than in crazy applications like homemade 2 cylinders.. But it's better to have something than to need it, I guess.
Tuning wise, you can get pretty much the same power out of a Minarelli or Piaggio.. Theres also almost the "same" parts available.. The Piaggio engine is a little beefier casting wise, but not that much of a difference. I've built 20whp engines with both Minarelli and Piaggio back in the late 2000's to early 2010's. Today it's "easy" (easier) to get 25+hp because of the parts available. (Theres way less parts today than back then, but more advanced and overall better quality). There's a couple of benefits for the Piaggio intake wise, because the engine mount is on the lower side of the engine compared to the Minarellis with their top side engine mounts, so on Minarelli you have to modify some stuff to fit a straight and short intake with air intake over the wheel.. The benefit for the Minarelli is that you can built a central suspension because the engine mount and the engine stand are far enough apart. (The Aprilia Area 51 for example has central suspension). Back in the day, optics was a big part of tuning over here in europe. So central suspension in an Aerox was a big thing. Today it might be unimportant.
In racing (which is still kind of big over here, both circuit and drag racing) Minarelli and Piaggio are eye to eye. Circuit is mostly Yog R/Aerox vs Zip SP/ Gilera Runner.
Making this video we hoped to create a discussion and get some great comments for all to read, Thanks so much for your input and sharing your experience👏 On the Zip you do the same , just add a water pump and radiator, same as any engine that has an Air and H2o Version.

The beast scooter of all time is the gilera runner 2T 125cc LC SP PERIOD!
Why were no gilera runners mentioned in this video?
Ahh yes in the 125cc category the Gilera is a fine machine✌️
We do not have many Gilera model in Australia. Although we did have the SP 125🙌
It's true for the morini I got a blown up engine it was the bearing on the left hand side
The Morini Crankshaft has an enlongated LH crank arm and it is susceptible to leverage on the bearing and loading from the transmission.
@scooterstreetau I saw that when changing it and I knew that it might be a problem later
I'm owning Aprilia SR50 Talmacsi replica with 768 km on odo.

Easiest engine to tune is Minarelli long Ac and the most power you will get out of is the Piaggio HiPer2 Lc.
Piaggio ftw. Especially the Hi-Per2 LC DD engines
Minarelli and Piaggio
What about peugeot
Also a great engine for tuning. Especially Blaster.
Man! I loyke chuning boykes.

GIlera? do you just not aknowlege it's exeicstence?:)
I must apologise for no explanation, but we never had the 50cc Gilera in Australia. We had the Runner 180cc and the VXR 200cc 4 stroke. The Gilera run with the Piaggio engine (and Purejet) so you can add them in at that level.
Honda strong on all platforms
Yes I love Honda products too.
Waiting for all the thumbs down from aerox owners. 🤣
I like the Yamaha mina engines. I must do, I've owned four water cooled bikes and a vertical BWS.
Yes the Piaggio design is better and has stronger cranks as standard. Even Malossi based the RC engines on it. But I like what I like.
Though you could tempt me with a Zip SP?
waiting waiting, they'll come. Aerox gives such good return for the parts and was/is a Favourite among so many.
Hm, stronger crank on Piaggio 🤔, i saw minimum 10 broken Piaggio cranks on the variator side, on Minarelli - never, btw i drive a Piaggio engine
