Hey guys, my buddy came to me with his bike and it's problem and i can't seem to figure it out so i thought maybe you guys could help. The bike runs fine under light acceleration and idles fine, but when you get on it some it begins to break up and the FI light comes on. So i tried to read the MIL code but there were none stored. It only does it when there is a load on the bike (ie accelerating), it won't do it just on the stand or in neutral. That's about all the info i have about it, any advice/help would be appreciated. Thanks

 

could be a few things. The fuel pump maybe going and not keeping pressure up.

 

pinched fuel line?
