NRG 49cc Change of jets

Hello i have a piaggio NRG 49CC sport series with a racing exhaust, i bought a polini racing air filter yesterday but the revs wont budge past 7 thousand, any help plz , i think its the jets if it is could someone please post some info thanks

 

ok thanks i would like to upjet it, because i will be adding more performance parts, could anyone give me advice on how to access the Jets and to remove the carb, thanks

 

cheers mate is it hard to access the bottom, do i have to remove the whole carb to get to it ?

 

ok so could someone give me abit of advice on accessing the jets and removing the carb, thanks

 

Can anyone please give me info of removing the carb to access the jets plz, thx

 

Its not essential to fully remove the carb. I find it easiest open the seat and remove the inspection panel. Then remove the airbox and the hose that goes to the carb. Then remove the intake manifold off the crankcase and you usually have enough movement to get to the bottom of the carb just make sure you do not damage or stretch the throttle cable as when you turn it on it may throttle lock. Hope this helps

 

ok cheers mate much appreciated
