In the last 4 days I have learned a lot , here , about “my” REX scooter ( Chona cheap type ?). Now also own findings adorn now my knowledge . e.g. I mean that this 125er , which in the original condition ! , just reached on the Tacho 82 KM/H , Real seems to be the 77 KM/H , should not be driven for too long with full throttle , also not close . I have found from my , after all 3100 KM thus in 4 months , faults , the presumably cause an overheating to take place t and the ignition system “disturbed” itself. I suddenly stayed on the 25th with the scooter and had to push at least 800 m before I came to a point from where I could expect helper (no cell phone with it!) This disturbance had already been indicated 2 days earlier(so that I would stay lying down///after!) in which the engine did not pull any more “gas”, as if it were swallowing; it even came to a motor run. Well, I had only about 1 Ltr. S prit in, but I think, after what I experienced the next day again, namely after approx. 5 KM with speed 75 approx. again these dropouts( I came afterwards stutteringly home, which it should be due to a kind of overheating of the ignition system, the engine block or all parts that can be affected with overheating. Due to my experience I would like to give the tip, who drives a REX scooter ( 50 – 125 ccm), should drive as little in the top speed range as possible, This would mean 82 KM/ HöchstG. eman should drive only just over 70 KM/H. I do it now so, have meanwhile already “again” 165 KM, so without stumbling. Or who thinks something else ?? Would I really be interested ! mfg. J.
