I am sure this has been covered some place but cant find much detail on it.I have just a stock 04 busa for the most part.The only thing i have done is install a set of yosh rs-3 bolt on cans.I am getting a small backfire every now and then when shifting from first to second.I have read about the pair valve removal have seen good and bad things said about doing it.I understand how to do it and would order a kit from brock racing but am unsure if i should do it kinda got mixed view's from other post.My main concern is a couple refered to the backfiring could damage the engine but didn't go into much detail about it.Again just have a set of bolt on yoshi cans not a full system the popping dose not really bother me I just dont want to damage my engine in anyway.Sorry if this is in the wrong area to post and for being so long winded.Thanks in advance.
