2007 RKC Need advice Please
I have a 2007 RKC. I put Screaming eagle slip on"s on it yesterday. I also have the "fullsac" dual conversion. So I am running true duals and SE slip ons. I was gonna stop there but a Screaming Eagle Big Breather just became available for $75 bucks. I love the look of it and will buy it. If I havent had any ECU programing done with the exhaust mods, and install the SE big breather what will be the effect on the engine. I just can not afford to get the Steelership to do the download/Dyno as of yet. Will it hurt the engine?
Thanks
BTW: I know about the ad on fuel mgmt systems. I just cant afford them as of yet

alternatives:
Ness Big Sucker on ebay from easternpc
about $120.
avantages:
easier install ( don't have to remove throttle body brace)
chrome backing plate ( which complements the black and chrome motor)
washable, reusable oiled filter media
Nightrider.com XIEDS ( about $130)
give a slightly richer mixture under most riding circumstances.
plug in install takes minutes & done.
These are the products I use on my 09 to good result and at good price

Ok I put the Ac and slip ons on. Road 200 miles and no pings, not one pop, and Great gas milage. The bike popped before I did the ac and mufflers. I took it to the dealer they search. It never had "the download" The mechanic took it out and said " dont change anything" it is running perfect. He said the the PO may have had someting done to it before trading it. I am very happy with it and apparently got luckey with free SE slipons and SE heavy breather for 75 bucks!

I'm no mechanic, nor do I play on TV, but what I have heard repeatedly is that if you change the AC you HAVE to have the download or have a tuner. Otherwise you're bike will run WAY too lean with the increased airflow and can be damaged by the resulting heat.
