The only way that 125's are usually restricted is through the exhaust. Theres usually some for of washer or something in there that restricts the exhaust that you can dremel out.

Pull the slide out of the carb then move the clip on the jet needle down one or two notches. This will richen the low range fuel mix. You can also get a rear sprocket with about 4 more teeth. This will get you off the line and out of the corners faster BUT it will also lower your top speed.

Please rate this solution. Thanks supergunner!

SOURCE: How can I fully derestrict a 2008 TDR 125. Bike


I suggest to check wether the carburator has a restriction in the holder
check if the clapets (between carb and cilincer) has a restriction
check if the exhaust has a restriction.

But overall: a race-exhaust, a tecnician who personalizes the carb to the local wether conditions by adjusting the jet, an eventually needed unrestriced cdi will improve bigtime.

greetings from a big 2s fan.

The carburetor needs to be removed and cleaned, water must be in it or some rust from the old can must have got into some of the injectors.

Theres a cell phone light on the dash of the scooter and i dont know what it is for on my keeway matrix 150cc

Usually when you drive a bike it's very noisy and you feel vibrations through your body, this will prevent you from hearing a call ring or call vibration, that light on the scooter shows you when you get phone calls (is activated by the waves of the call you get on your cell phone).
