XR650R airbox/left hand side cover modification by team Honda

Can any of you guys tell me where the original Honda version is of this mod?

links or pm me please

I recall a bulletin being available that describes in detail what team Honda do to open their 650R airboxes up?

Thanks

The bulletin comes with the HRC kit.

any chance of scanning it and emailing to me?

If I still had it I would, but its long gone. However, in the article I wrote years ago that's posted on 4strokes, the drawing in the upper right hand corner (click to enlarge) was from the Honda bulletin that's included in the HRC kit.

How does this mod work on otherwise stock (uncorked) bikes? Precision Concepts told me not to do it using a stock cam.

xr's only too i did it to mine like 25 bucks and some time. if you buy the panel pre-done it's like 99 bucks

Can you guys explain where I might get #30 mesh from?

Are there any other terms for it?

Is it a specialist type mesh or would I get it from the hardware store?

#30 refers to the size yeah?

I forget the #mesh that I bought but when I did mine I purchased "hardware cloth". It held up great!

What does the inside of the cover look like?

Yes, #30 refers to the amount of openings per linear inch (25.4mm for you :thumbsup:) of the woven material. So a #30 mesh means there will be 30 openings within 25.4mm from the center of any wire to the center of a parallel wire of the woven material. If you can't find #30 mesh, then finding something close is good enough. Also, my advice is to pay the money and get some good screen made from T304 or T316, etc, stainless steel so it does not rust.

What's the use in doing the mod if you don't have the HRC cam?

to make the bike breath better.

any bike can be made to breathe better.

I run the hrc cam in my 628.

Blais Racing offers a kit to do the side panel.....also offer a complete sidepanel as well. http://www.blaisracingservices.com/html/xr650r_14.html

I don't recall ever seeing one XR with this kit on. Anyone have it and a pic?

The others look good too. All these methods applicable to the L as well?

It might take in more air but that doesn't mean it breathes better. Honda does not recommend the mod without the cam. So who's right?
