If you let bike sit for a while fuel will gum up jets in the float bowl...we all know this and hopefully drain our float bowls if bike will be sitting for more that a couple of weeks.

What many don't know is that fuel sits in the accelerator pump resivoir and can do the same thing. The passage way for fuel to get from resivoir, through float bowl and into combustion chamber can get clogged with gunk just as the jets can. Try cleaning your accelerator pump passage ways.

What's the ambient air temps currently where you live ? Is your bike jetted stock ? Be more detailed in your question for a more detailed answer....
