Your tune is really fucked up if you are blowing flames out the pipes period.[/url]
Oh hell, he spelled period, it must be truth. OOORRR, I have wrapped pipes so I retain exhaust heat and air velocity through the exhaust. So when I let off the throttle, the unburned fuel is heated, mixed with air from the PAIR system and ignites.
Both my bikes, which have wrapped pipes, do it. But hell, I could have two bikes with "fucked up" tunes. I'm guessing Honda released the "fucked up" tune on a special edition of the 919. You know, since my bike is essentially stock otherwise.
Then there is my XJ650 with spits flames. it has a microsquirt controlling 05 R6 throttle bodies and injectors. It is tuned at 12.7afr under WOT by O2. Could also have the 'fucked up' tune installed though.
Hope you know trolling when you see it... Don't get your undies in a bunch, all in good fun.
Bigger issue, are there other benefits to removing these systems?
