So ive been having this problem recently and cant quite figure out what exactly is wrong... when i turn my bike on it usually idles at 2000rpm until it warms up and goes down to 1500... recently, its been idling really low 1000rpm, and when you try to give it throttle it feels like its bogging or going not using 2 cylinders (all cylinders are firing)... if you ride it half a block when this is happening and then let it idle itll shoot up to 3k and idle... im so confused ..... also today same thing happened, i let it warm up and started riding, but when stoppped at a light the bike started idling at 1k again and then stalled on me and had a lot of trouble turning back on.... everything works fine as soon as the bike warms up.....

Im thinking its the battery kicking the bucket, or because its really cold the battery isnt holding its charge???
Can anything else cause this???
Im taking the bike apart for the winter, so ill prob figure it out then if no one helps out here... thx for the help

 

Sounds like it could be the FPR
