Well, you can atleast tell me what pipes are on it as well as the air filter setup. Stock filter with lid? K/N with lid or with out, clamp on k/n's (pods)?
But quickly pull out the spark plugs and see what they look like. They could be fouled out, i would replace them anyways, there cheap.
Ok, do NOT take it to some Clowns to work on it when jetting the carbs will take you 20 mins tops and proly no more then $20 in jets. Or if you want some idiots at a dealer or shop to change your jets for $200 then then there you go. DO NOT get a dyno jet "kit" !!!!!!
What do the Carbs say on the side of them. keihin or Mikuni?
IMO, this is a jetting issue, very so simple to change them out and yes you CAN do it if you can turn a wrench and a screw driver. You can do that cant you?
Anyways we can do the work for free right here for you, all you have to do it turn the tools and ask questions.
But you need to tell us what jets are in the carbs first off.
Here is a link for you to read a couple times. very informative. http://www.dfn.com/benkaren/jetfaq.html
Let us know when you know the jet sizes .
