Hopefully this is the right spot to post this..... but anyways, Hello! In need of some help. I own a 2005 Roketa 250 with dual carbs, For some reason it will start, run fine, and sometimes the engine will just stop having the ability to rev, I can be riding and all of a sudden the engine will bog down and just idle, even with choke on or off it will just idle, and when throttle is pressed it will bog down but still idle roughly. if i leave it sit at this idle for a while, maybe 10 - 15 minutes it will all of a sudden rev up and act perfectly fine, I then can ride for almost as long as i want.... wierd,

I have taken the carbs apart, even separated them and cleaned them thoroughly. the fuel petcock has been cleaned and the tank has been cleaned also. Any help greatly appreciated....
