Hey all, im not sure how many of you ride motocross bikes but i thought id ask anyway because im not sure if road bikes have them. on my 05 KXF 250 most thumpers have backfire screens before the air filter but i have read that it restricts the air flow and alot of racers take them out... i was wondering if you thought this was a good idea or if you know any1 that has done it.

I'm not sure on this one, I'll have to a word with a friend or two, I'll try to find the time to learn tho.
Si
