problem with my piaggio typhoon 125

[iowc-scooter]

iv had my 125 for a few months now and its run fine untill not long ago as it starts up fine n warms up fine, but once i get going i notice a slight loss in power, then when i stop at lights or traffic the revs drop dramictly and the bike stalls.
iv cleaned the carb out and changed the spark plug and made sure there is plent of oil in it along with fuel, but the problem seems to stay can any one give any advise as to what it could be *D and how to fix this problem cheers

Maybe the "rubber" between your cilinder and cilinderhead broke. Another possibility is bad cooling. Does it still get enough fuel in the carb (try to clear the carb of all gasoline and then starting your scooter.. if the carb doesnt fill up with gasoline then that is your problem). Does your sparkplug get all wet?
