Out riding with some buddies today and one of them said he saw some flames come out of my exhaust when I was hard on the throttle. Is this normal? Should I be concerned? Thanks..

That would be running really rich and for a new 05 CBR1000 .... I'm not sure that's normal. What mods do you have?

Wouldn`t have to be that rich, with the P.A.I.R secondry air intake on the 1000rr bringing fresh air into the exhaust to burn unburnt fuel off(that`d be all the pops you hear on the down shift) hard on the gas i`d expect some detonation. Shouldn`t be anything big though.

Just Two Brothers slip on and the flapper mode. Maybe I was decel and then back on the gas hard and had some fuel/gases left in the exhaust maybe. Installing PCIII next week, that should fix all my problems with too rich, too lean issues shouln't it?

If you get the pc3 then that will sort it perfect with a custom map.

I am not sure about Honda but on those other makkes there are block off plates you can buy to block of the clean air intake thats foun inside the airbox. I was told by a Kawi rep this also ads a few poniesl. helped a friend complete this and made a world of a differance, No more pop or flames. If anyone has done this on a 1000 let us know. thanks
