Cool, to be fair I don't expect my 125 to go any faster I just like the look of the open space under the seat haha. I would put a smaller filter on purely for cosmetic reasons, I just don't want to ruin the engine!

Im looking to give my 2011 ybr custom a more stripped back look. Ive noticed customised 125s with a much smaller cone air filter instead of the big box. I've read that this can cause fuel mixture problems and as a complete noob, this could be well over my head. Does anyone have any experience of doing this job?
