Restricting these vehicles to 28mph is one if the most dangerous pieces of legislation. On a par with "smart" motorways not having a hard shoulder.

[@Ridingreviews]

I agree with you

[@ServeraServera0]

Some laws are straight out stupid, really outdated ot both Raced my restricted supermoto against a friend on his bicycle, I lost

[@Ridingreviews]

@ServeraServera0 i agree. Did you know a police officer has to give a pregnant woman his hat if she needs to pee

[@user-sf7kl9uh7k]

​​@@RidingreviewsThat's not true, it's actually BS. Although a police officer may make an exception to allow a pregnant woman to urinate in a public place.

[@skyrider29]

Maybe someone should start a safety campaign so these mopeds can legally do at least 40/45 mph as they are so dangerous for the young rides being restricted to 30 as the don’t have the power to get the rider out of some unsafe situation

[@Ridingreviews]

I tried. i didn't get enough signitures

[@peterbennett4948]

Good simple explanation 👍

[@Ridingreviews]

Thanks for watchin i apriciate it

[@hiyadroogs]

So, retaining the 28 mph speed limiter & increased variator weights would hold the engine revs down to 6500 or 5500 with the 63 & 81cc conversions, & may maintain stoichiometric air fuel ratios over a narrower rev band. But the extra torque & therefore hp from the increased capacity will assist climbing speed.

[@Ridingreviews]

a bit more technical than my explanation lol

[@hiyadroogs]

Good explanation Chris. I have 2 Leeway pizza delivery scooters from CBRUS. The Chinese have been fiendishly clever in restriction. Speed limiter sensor on the clutch bell housing. 2 x electronic pressure sensors mounted above & below the vacuum controlled carb piston that controls mixture. An electronic sensor that detects carb butterfly positioning. Oxygen sensor on the exhaust. & all connected to the rpm restricted ecu of course. There's no way to disconnect the speed limiter, as disconnection, or changing the clutch bell to one without magnets puts the ecu into limp home mode. Changing the carb, ditto, as it will lack the non interchangeable butterfly sensor. & vacuum sensors. Grinding off 2 of the 4 magnets on the clutch bell may fool the ecu into thinking the bike is at half speed. But it won't increase the rpm limiter or power output. 2.4 bhp @ 6500. 2.8 @ 7500. It isn't fitted with a standard GY6 carb either, since the main jet is 6.7 mm in width, not 4 or 5mm as standard. Can't seem to find one of larger jetting. 82 as standard. The speed, 28 mph by GPS is fine. Just want more climbing power. I've fitted one engine with a 63cc conversion. But without an increase in the 82 jet, it will run very lean. I was thinking that fitting the 63cc with original 82 jet, but fitting heavier 6.5 gram sliders, will pull the engine revs down to 6500 peak (maximum torque) which from the 26% increased capacity, will give 3 bhp @ 6500. It just won't rev out like the original engine. Would this work? I also have an 81cc cylinder, which with the 82 jet, would mean fitting a 7 gram slider to pull the engine down to 5,500 max. It's all I can think of in the absence of finding an appropriate jet. What do you think?

[@Ridingreviews]

so the pickup on the clutch housing is ware it tacks the restriction all the other sensors are for emissions and choke I would try taking the sensor out of the housing and see what happens because the bike with no belt should rev out if you just disconnect it it thinks you have tampered with it

[@hiyadroogs]

@Riding reviews Thanks Chris. I'll give it a try.

[@Simon-jh1hf]

In Germany there is another smaller class, its calle motorized bicycle and after having to ride 15.5 mp/h for 2 months, it was a blessing for me when the 28 mp/h ECU arrived. With a 4-speed manual transmission it's really fun. But at 28 mph it's already running at 8000 rpm in fourth gear and if you open the ecu on the engine complete would probably explode or something lol

[@Ridingreviews]

this bike in the video will do 30mph at 7000 RPM in 4th gear and will run fine for distance at 10000 rpm at 40 mph they are tough little engines

[@Simon-jh1hf]

Now that I'm driving with the 45 km/h ECU, the 25 km/h ECU is just lying around. Are there companies that reprogram it so that it is open? I've been looking for 3 months now and there are definitely no open ones for my moped to buy. Everyone says "yes, there are companies they unlock them" but no one could tell me one that would do that and I couldn't find any myself. This here is the end for me now, right?@@Ridingreviews

[@Ridingreviews]

@Simon-jh1hf yamasaki.co.uk do remap, but it is for uk only

[@1381432]

is appreciated another video about a 125cc euro4 (keeway superlight). Thanks in advance

[@Ridingreviews]

I havent seen many keeways superlights this year

[@GB-Patriot]

Great explanation of the rules Chris. Maybe show us the remapping process. Also would changing the front sprocket on a ym50 make any difference.

[@Ridingreviews]

Im not sure about the remap video i dont think anyone would let me use there equiptment to do it putting a 13tooth sprocket will make it faster but you would lose talque

[@Simon-jh1hf]

How is that supposed to work? Even with a larger sprocket, the ECU still limits it to 45 km/h (28 miles) If you then change the sprocket, the thing still drives 28 mph but with less acceleration. And even if you remove the limit of the ecu and change the sprocket, the engine is hardly strong enough to get anything out of it because all the emissions standards... catalytic converter and all that shit.

[@pertythelordofiron8617]

Any thoughts on the wk gtmax 50 ? Older rider that just needs a littke more juice for hills and pullling out

[@Ridingreviews]

essentially all 50 cc scooters are the same Yamasaki have one as well called the Joker 2 they all have the gy6 engine in and all produce the same amount of power

[@nikgeld5484]

That 28mph limit is absurd,i can drive a 44 ton truck at 50mph but cant ride a scooter faster than 28 mph,totally outdated 😂

[@Ridingreviews]

I agree with you

[@Ridingreviews]

go to the manufacturers

[@barneyhubert7078]

I have a Yamasaki f31 and I find the bike gear 4 doesn't really add much to the speed compared to gear 3 (only a couple mile an hour difference if that, as I am able to get to just abut 30mph before needing to change gear) and I have checked the bike has a 13 tooth front sprocket. What recommendations would you have to increase the speed. I'd like to get it to around 45 mph if that is at all possible without sacrificing its hill climbing ability too much which already isn't the best doing most hills at about 25 mph. I also know the guy who had the bike before me bought it new derestricted and he could go about 45 mph on it but then after taking it in for his second service they re-restricted it so I don't know if they could have done anything differently to re restrict it.
