is it when you first pull off of a morning? and if yes does it improve after say 30 secs of moving? if yes then its just where your engine is warming up. for that just leave the bike to idle while u put your gloves etc on. you may need to use some choke. also. if its every time you pull off, it may be the cold weather causing carb freezing, that feel like your riding with the choke open and so not alot of power. so for that just add some PRO fst to your fuel mixture. make sure you get the quantity you add right though!
