Hi, having trouble with my bike. Everything goes well until you open up. it looses all power and comes to a stop but continues to idle. Seems to happen just before the powerband. I did clean the carb but no luck. Could it be the jets? The bike has been standing in the garage for a year. Any help or tips will be appreciated.

Sounds like the main jet is blocked/restricted, or the float height/fuel level is wrong so it runs out of fuel as it is demanding more to come on the pipe.

Either could be the cause but as it runs ok up to the power i'd go with the latter. You may even find its a blocked filter restricting the fuel flow. It will idle ok because the fuel for the idle is done differently in the carb and is not as sensitive to the fuel level. Ditto it wont be affected if the main jet is blocked/restricted.
