It's been a while since I had a machine. I had a modded 400ex. Now I have a stock 450r and want to do a couple of cheap things to liven it up. Basically, I am putting a K&N filter in and a different end cap. I believe stock jetting is 118? Any ball park on this would be appreciated.118 seems like such a small jet to the 400's 148. I have a bunch of Keihin jets from my 400...are they the same style jets? I wouldn't think I would have to change needles with the little bit I am doing to it at this point. Maybe raising it a notch at most? I would prefer to use real keihin jets as knock off jets are often differently sized. I am trying to keep the lid on at this point.Thanks
