how much gains should i expect?

[joe250]

I have a 250ex, and just got done ordering a big gun slip-on, K&N airfilter, and jet kit. i was wondering how much power gains i should expect. It is all stock. Also how hard are jets to install? this would be my first time, does the k&n jet kits come with good instructions? thanks in advance.

Well depending on what jets you put it in i'm guessing you'll have about 15-20% gain in power with the pipe. And for the jets mine did come with some basic instructions, but nothing detailed. I would get someone who has done it before to help you with it. Hope this helps..

Yeah Blysster hit the nail on the head,,,you'll most definitly be happy with the mods your putting on it and if possible grab a buddy that's familiar with jetting,,cuz it can be a headache if you start off in the wrong direction.
