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👍
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.
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.
@@craigatyeo7965 peugeot engines are made in house. They are good for sport setups. Maybe low midrace. Higher than that will need to involve custom work.
That's great thanks for the reply👍I've got a mallossi sport kit,full circle crank,dellorto phgb mallossi gear up kit all to go on.hopefully it will work out ok. Thanks again
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 🔥🔥
@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 🙂
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
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.
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 .
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
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.
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
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?
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?
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 OEM Piaggio KBC Korea crank bearings are also crap, mine had a huge gap on 5000km(i bought it new)
@@scooterstreetau cracks only on two stroke Piaggio engines, and always at the same place, between oil pump gear and seal, looks like you cut it off, 50-125-200-.....cc four stroke don't have that problem
I have a china gy6 50cc I put BBk and other bits n bobs and struggled tuning the carb come to swap back to stock cdi and it runs perfectly tuned but still have rev limiter... headache but I can just laugh about it now but I love the Japanese bikes
@@scooterstreetau got a 24mm cvk carb to make it easy...and I bought 2 different cheap dc cdi's one adjustable but both don't work but stock run perfect brown spark plug...dose need exhaust still tho..thanks
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.
hi you seem to know what you are talking about when it comes to making a set up that works, what would you suggest for the best acceleration and midrance set up for my Aerox 155 2023 model, I don't care about top speed, I live on an island so acceleration and cruising around + engine power to get me over the mountain is want i want not topspeed, hope you have some good tips for me
Check out the products here, excellent for the Aerox155 (NVX) motogaga.com/1087-aerox-nvx-155?order=product.price.desc Big bore kit and race ECU. variator.
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. www.malossistore.com/en/au/gilera-runner-50-2t-lc-giru50-M
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.😲
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.
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.
@@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.
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
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
@@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👍
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 ?
@@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
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 ?
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.
@@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
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.
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.
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.
