Hello everyone,

I'm planing to build my own FMF megabomb exhaust header for my honda crf250r 2009.
Why I want to do it on my own and not buy it is because I love welding and doing that kind of project.

I have checked my friends megabomb of kawasaki kxf250, which I measured and did 3D model.
I would need info from someone who have megabomb on CRF250R 2006-2009, because the holes inside the bomb are not in the same position as in kawasaki which I measured.

So if someone can help me and measure this dimension on picture I would appreciate.
I would kindly ask you for picture of holes inside the CRF250R 2006-2009 megabomb header.
And if someone could do outline contour of the megabom (contour on piece of paper)

When I got dimensions I will start ASAP with welding and posting the pictures of the progress

Sorry for any language mistake (english is not my first language).
those are one of the dimensions which I need
holes inside KXF250, looking for picture and info of holes inside CRF250R 2006-2009

How to find diameter of hole and position of hole.

I'm mildly okay with this...for now. The minute these are offered up for sale, this is going to vanish like a fart in the wind.
