Hi martin, I'v tinkered with quite a few 2 stroke moped engines and the jetting can be a real nightmare to get right, i was told by a motorcycle tuning specialist that a good guide to upjetting is to buy 3 jets, one + 5% one + 8% and one + 10% larger than the number that the standard jet is stamped with, it can save a lot of time messing around thinking of what size jet to buy next if the previous jet doesn't work might help :)
I love the music, Martin. I felt like i was watching a gameshow. Announcer, " let's play derestrict that engine. Here is your favorite host and mine, Martin". 👍 Great vid and very helpful info, thanks.
I've got a 50cc scooter martin and as soon as the weather gets warmer I shall be getting it deresticted now I know what's what. Great instructions on how to do it martin thank you Rob
Here in the Netherlands we also have those bloody rings in the exhausts, i usually take a few old dremel discs and use them on an old file or something until they fit inside the end of the exhaust and get it out that way, usually takes 3 discs.
I saved a copy of this video for reference, Thanks. For some reason, my China 150cc scooter came with a "Speed Limiter" according to the paperwork. Since I don't know exactly what the Chinese company means by "Speed Limiter", I'll check all these places plus the CDI.
Chinese scooters and bikes generally copy Japanese style restrictions using the CDI 😕 although a buddy found a cone of death in the exhaust of his Taiwan 50
@@davidgraemesmith1980 I still haven't checked these places because I'm still braking the bike in but I'll do it by summer. I don't want to change anything from factory specs until it's well broken in. I just don't get to ride it that frequently. I'm also a little hesitant because I don't have my motorcycle endorsement yet. I'm struggling to perfect figure eights which is what they skill test on. Thanks.
The outer pulley should have a plastic fan on it and when replacing the pulley you should pull open the rear torque drive pulley and push the belt down to allow slack on the belt so you dont pinch the belt when replacing the front pulley.

Great that you show the working parts..could you please look into a video of derestricting the Fly 50 4V that came to the US market in 2012... The only other video for that currently on You Tube is all talking, it does not open the scooter insides at all. Since you did an excellent audio and good video here for the 2 cycle, I would love you to be the FIRST and only one to do the 50cc 4V,,,!!!
fact back late 70s 50cc bikes were pushing out 4 to 5 hp,and 80s plusrestricted bikes 50cc put out about half that amount its an easy fix,for the record same went on with 125 cc restricted down,it was that bad on 125 at one stage that 80cc bikes had the same power output.
Another cracking vid! Hope you are not snowed in. We've had a fair bit in the Midlands and my mum and dad in Spalding have had a lot too. Bet Lee is glad of the syrup, I mean hair system, in this weather ;)

Hi thks four your great video I buy a Piaggio Zip 50 2T from 2015 I won’t a little more speed what parts you recommend to buy the sport clutch whit blue springs I buy or ready any more you recommended thank you very much
Just make sure the restrictor ring in the exhaust is removed and check if the variator has an extra spacer ring that restricts the speed. Some carbs also have a restrictor ring on the inlet. After that, you might need a bigger main jet. That should be a good place to start.
Hi, did you check the rollers inside the variator? If they are flat spotted they need changing. Only cheap and make a big difference to the transmission.
Great video once again. Great tips there. When I get mine tomorrow, I will be checking mine for restrictors. Although mine is the 4 stroke 50cc engine. Early on in the vid, when you showed the ring on the variator, at 2:32, the belt didnt look too good. Looked a bit chewed to me. Looking forward to the next vid. :)
I am trying to trouble shoot a problem with my et2 was running normal for a stock scooter riding around neighborhood to give the battery a little charge and came upon a speed bump unexpectedly ,did the motorcyclist thing at last minute full throttle over bump caught air and after landing scooter began to sputter as if a fuel problem then died and now won’t start even when opening throttle thinking it might be flooded . Where should I start looking? Thanks
Nice video thank you but i wish you could give approximate speed increase after all that lots of work my personal opinion I wouldn’t do all that work for 5 miles even for 10 miles I would think bout it
Could be wrong as I’m watching on a tiny screen, but a common problem with rotary tools is that the little plastic cap comes off the locking push thing (and usually the spring too) which causes that rattling sound and can get stuck and cause smoking, buzzing etc, it looked like yours was missing, so might be worth checking to see if it is just that.
Nice video martin .shame you didnt do a befor and after performance vid .its a pity in 1980 you didnt have all the bigbore kits that are available today .although they were plenty fast enough i guess the unristricted peds
Question Sir: Would I have to do all 3 restrictions to gain a little more speed? I have a 2016 Piaggio 50cc 2T and it's struggling to go over 44 kph! Any tips welcomed!
@@retrorestore Thank you for the prompt reply - I noticed that my exhaust has a tube that run's off in to the EXHAUST AIR VALVE see following image ( motor-vehicle-madness.co.uk/piaggio-zip-2t-50cc-exhaust ) and a pipe that's already pinched. The pipe running off to the Air Valve, is this the one that has to be cut? what would happen to the Air Valve.
You forgot your disclaimer, It’s actually illegal to ride a de-restricted moped or scooter unless you have a full bike license or a CBT. A full car license doesn’t cover you.
Gary fisher. Once a moped is de restricted the rules on who can ride them charges, I wasn’t having a go at Martin. Licensing rules are a nightmare, and people need to understand them before modifying cars and bikes alike.
Paul Wright its not illegal to derestrict your scooter. You can do all the modification you want to it. You just better not actually try to drive it on legal road withput the proper license.
Another question. Now I bought a 50 cc 2t vespa primavera and I sort the site from the carburator and I put a 60 jiggler. It's running very well my speed is about 65 km I'm happy with that speed . Do you now if I have to modify something at that oil pump are it will be fine because it was a 53 jiggler and now it's 60. Thankyou very much
Hi Martin great video as always, just out of pure interest and for others that may de-restrict there’s do you know the legality side of this? All I really know is you will have to tell the insurance. I know I know yawn a boring question lol. All the best. Steve.
Not part of my skillset i'm afraid Steve. Basically, even if you change the wheels on your car or bike or put a non standard radio in, the insurance wants to know. Rule of thumb, always tell the insurance company of any modifications you may have to your vehicle.
Thanks for the reply’s gents, as I said it’s just out of interest for me, yes it was only recently I found out that something as pedantic as changing the radio you have to let the insurance know, I would understand if it was an expensive unit. All the best. steve.
66 jet is gonna be way too rich. A 58 (60 tops) should be good, if the 53 was the old jet. Ditch 2 or 3 vario weights (free mod)for better performance.
Friday night kids in bed . wife's a work im sat with a nice whisky watching this happy days. a 66 main jet you may get away with that with a k&n or free flow air filter
Ive tinkered with a few of these bikes and with those carbs to run a open filter you need a really big main jet, something around a 80-90, ive even known people to need to run over 100 with 70cc kits using this carb and a open filter. on a 50cc kit anyway a open filter is pointless, just use a load more fuel and make lots of noise.

Hi Martin thanks for the video. Does removing the exhaust cone restrictor increases the noise? Thanks in advance
no it doesn't
Really nice video, Thank you!

Are you sure about the restrictor cone in the exhaust? Maybe this is actually necessary for the resonance in 2 stroke engines.
No, its a restrictor bud.
Wonder what top speed you will get! I hope the brakes are good!

Check for spark and then fuel delivery, squirt a bit of easy start in the back of the carb to see if it fires.

hello, great video, thanks! how much speed do you gain after those modifications? i have a 2013 Vespa S50 2T that goes 60km/h right now.
We got it to 85kmh with me on it at 16 stone.
it seems that is already unrestricted. The top speed is 60. the carb is stock, with 53 main jet. Do i need to change that too?
