Piaggio NRG Power DT 50cc 2007

Hi Hrb21 and welcome to the site:smile

First thing,when did it start doing this,was it gradual or all of a sudden? what mileage has it done?and has it had any work carried out on it lately?.I can speculate,the most commen reason for a moped to get stuck at a certain RPM is the rollers in the variator getting flat spots so they can't roll, or the belt is starting to shred, blocking exhaust either at the exhaust port or at the stinger(tail pipe)another can be a dirty air filter,or a air leak,give you something to think about!Good Luck

KCMC:tongue:

Losing Power

I recently had the same thing with my bike.  Cleaned the carbs with no effect.  Turns out there was a partial blockage in the fuel line.
