Hi all, so am looking for some general advice please.... Feel free to point me in the appropriate direction... I ride a big bike ...and have a 15yr old memory of an old Suzuki 50cc 2 stroke... Just got a really sweet little 2022 euro 5 Lexmoto Echo 50cc. 1600miles. Starts on the button, no problem. When riding... It needs almost full revs to get going...and even then it may slow right down (physical speed)... And likewise if you quickly give it full throttle it seems really slow to pick up speed. Also pulling away you need to twist throttle slowly.... It almost feels like the "clutch is slipping" as there seems to be revs but no drive....or too much drive and so it almost stalls.... On the straight it does slowly pick up speed to 25mph....and could maybe, given long enough go a tiny bit faster. I am not expecting much but hoped I may get to 30? Is this simply the foibles of a cheap, Chinese, 50cc moped trying to move my 16 stone? Or is there anything I can check? Have just done oil change and spark plug. Belt looked ok.... everything seems clean and tidy....barely used. The old spark plug was slightly fouled - bit of oil on the electrode. Engine light came on when warm...I am hoping this has been sorted by an oil change/top up....or what else could I check!? Or am I simply expecting too much from a tiny bike compared to what I am used to? Many thanks for any help.
