I recently bought a cheap Chinese moped/motorbike called a lexmoto hunter 50 and I have been trying to figure out how to derestrict it. I have watched many videos online about other bikes, but I can't find anything about this one. I have looked in the exhaust but I can't see a restrictor there, I have looked in the carb and can't see a restrictor there. Does anyone have any suggestions at all?

Maybe it’s gutless from the off??
Why bother restricting it if it’s crap to begin with.
Lexmoto...... 50.... see where this is heading smile

It's restricted to 30mph. On the manufacturer website it says that it is restricted.

Is it electronic ignition? Perhaps that's the spot?

It’s a Chinese 48cc air cooled engine rated at 3hp. How much do you think it’s capable of making?
For an engine that anew crank costs 27 quid and a new head is 55 don’t expect it to be a pocket rocket in waiting.
The carb is probably tiny, the inlet is all over the place, the timing is not going to be aggressive. Maybe it’s making exactly the power it’s capable of making??
Not sure btw where it’s stated as restricted??

This is not the same Lexmoto model but I'd guess some of the theory is the same..
Worth a read and may answer a few questions on restriction / derestriction of the lexmoto's

OP, are you 16 and on your first bike or older and bought something cheap and cheerful?

If you are lucky enough to be a teenager then, legally, you're going to have to put up with the restricted 30mph until you are 17 and can move up to a 125.

If you're older, you need to find a gullible 16 year-old to sell it to and then buy something bigger.

Derestricting a 50 is generally possible with time and money, but effectively you're just turd-polishing...

Sell it and buy something else...

When I was 16 I had an Aprilia RS50 with a 19mm dellorto carb and Arrow exhaust and that was good for 65mph on the clocks. More importantly it looked like a GP bike which is what you want when you’re 16...

That’s assuming you’re 16, if you’re older I’d sell it and buy a 125.

A 50cc four stroke won't be worth the hassle of messing with. If you are 16 you will need to buy a 2 stroke bike to de-restrict for more speed.

My Aprilia rx50 had a cone in the header part of the exhaust. Took it out and would read about 55mph

In my 'dizzy' yoof I had a Yamaha DT 50 which I threw a lot at it. big bore kit, exhaust, reeds, carb etc etc etc.. Now I probably ruined it but I have to admit at that age, seeing 70mph on the clock once was wonderful. Obviously I cannot condone such behviour if you are 16 today.. biggrin

i have one and it does 45 without fiddling with it at all, it needs to be run in correctly to get some more speed, if not, there is a thick rubber gasket in between the carb and the exhaust manifold, remove that and youll be getting 50 or more

So then. I also have a Lexmoto Hunter 50cc. I have put a new 125cc exhaust on, and a NKG CR7HS Sparker on there. Now down hill flat out it goes 55mph, and on the flat 40-45mph. Put some decent Castro oil in as well. Hope this helps

Where did you get the exhaust from?
