NEED HELP !!!!

As I was riding home my bike went from full revers and dropped to half and kept juddering when I was riding please help thanks (piaggio nrg)

 

checked your belt lately?

 

No I haven't took it to a piaggio dealer for a new piston and few months ago and they never picked up on the belt being warn but I will check thanks a lot

 

Check your spark plug, it might be fouled, causing an intermittent spark.

 

Hi merlin thanks for the advice will also check that one out

 

Update checked the belt everything seems fine it looks new when I go to strt the bike up it idels fine but as soon as i go to set off it Boggs out and cuts out any ideas??

 

It could be water in the fuel, try draining the carb float bowl down and see what comes out.

 

Might also be a split in the manifold letting too much air in, or a blocked jet

 

No crack in the manifold and I have the carb of now and just checking the jets
