2003 rincon in limp mode

Any suggestions on how to figure out why it’s in limp mode?…it idles fine and after about 1/4 throttle it spits and spudders. I don’t think it has any codes that I can tell. Is there any way of pulling a code on this year model? Not sure where to start. Any help would be appreciated. Thanks
