Backfire screen

[EtienneNXR]

Read on the xr250/400 mod thread about a backfire screen?

I assume its the thing under the airbox, like a copper type plate with round holes in, with wire mesh at the bottom?
Will removing this make the bike backfire?

Backfiring is cool! I like fire

I think you will find that the back fire screen is in the silencer, its basically a wire tube that stops flames spitting out the exhaust and prevents fires on the trail supposedly.

I think the backfire screen is to stop a backfire setting fire to the air box and ultimately the bike.

The screen in the end of the exhuast is a spark arrester, . . . compulsory in the states i think, so you dont set fire to the 'dry brush land' . . . (not much chance of that over here )

Thats the one, my mistake and you are correct my apologies

No it won't make it backfire. It's just as airwolf said, to stop your airfilter getting burned if it ever does backfire.
