    Hi All,
    Just picked up a Lexmoto Nano from a local take-a-way that went bust for a good price. 19 plate with 55 miles on the clock.
    How do I un-restrict these things pls? I have googled such query and I see something about removing a wire from the CDi unit. However, I cannot find anything specific to the scooter and don't want to mess anything up.

    Sorry if this has been asked/answered in another post.

    Stay safe.

    I've just had a quick Google and found on a Danish website that the VGA N1 (same bike) has a restriction via a sensor in the back wheel/transmission (I'm not super good at Danish I just skimmed it)
    It will be a single wire going into the transmission case or to the back wheel, it measures the wheel speed and limits the CDI.

    On a few Peugeot scooters the wire is blue, could be the same here

    Afternoon,
    100% no wire going to the back wheel/transmission. Would this point to the CDI where I need to remove a certain wire?
    I also see something about removing a 'nut' from the top of the carb but unsure if this applies to this bike.

    Thank you for any advice as the bike does it's best to stick to around 27-29 MPH whilst going downhill. So 100% restricted.

    Wouldn't matter what engine was in there, the restriction is inside the ecu.
    As scuba says, either replace or remap

    Thank you, I notice the variator washer has a ridge on it, so I assume this is what you mean by grinding down? I was told to obtain an unrestricted ECU so I did and it's done nothing.
    I will be honest I'm not that good with bikes very basic with knowledge.

    ECU was Dellorto ECU Unlimited / unlimited | euro 4... came from Jordy's Garage in the Netherlands. I swapped it with the current one and all I noticed was the rev's could reach 8000rpm plus a little more but still no extra speed. Do you think if I grind down the variator and put the ECU i purchased back on it will give a little more speed?
    Nothing to change in the carb?
    If I did not pay so little for this bike I would not be bothering, just sell it on. I got my son one of those direct bikes scooters. I disconnected some wire that goes to the back and it hits 40mph NP !!!

    Any help you can give is very much appreciated. I'm in Oxford so unsure where u are.

    Thankyou

    Grind down the washer on the Variator That Will get u to about 32ish on standard rollers and clutch
    and air filter

    If you want better top end get heavy rollers but will be slow take off Or for a decent take off and still have top end change to a sport clutch with +2000 springs and put a k&n air filter and use 6g rollers = [Standard] will get u to about 37mph on flat 40mph down hill

    with ecu that may just Restrict revs so u can try it not found one to try that yet

    Thankyou for you prompt reply. Let me grind down the washer and try that. What weight rollers should I try and where did you get yours from pls? I will try that unrestricted ECU again.

    Thankyou for your help here.
