I don't think there would ever be a FI issue so expensive to repair that would make it feasible to even consider doing that. I'm sure that a carb intake manifold wouldn't even fit onto the heads a FI bike. I know the intake gaskets are a different shape.

Re:Fuel Injection Facts and Tips 3 Years ago  
My first bike was carbed, then I got the '09 v-star 950. Fuel injected etc. Night and day, turn the key push the button and ride. That bike got ridden 14k miles at all elevations and in all conditions over a 2 year period. It never quit on me, never failed to start, and all I ever did was keep the oil, plugs, and tires in good shape. Once or twice a season I would put lucas FI cleaner through the tank...

If you know what you are doing, and have the tools/equipment, the ECU CAN be reprogrammed.
I have mentioned before that we had Toby's ECU flashed, and his Stryker runs much better now.

The guy that did Toby's is currently working on a flash for the v-star 950, and he said after he gets that done, he will be working on a flash for FI Roadstars.

Yamaha has to program our ECU the way they do for EPA purposes, which means the bike doesn't run as optimally as it could, and all your after market tuners are doing, is over riding the stock ECU.

The other thing we did for Toby's FI stryker, was adust the TPS (Throttle Position Sensor) and unplug the 02 sensor. The TPS setting was very important for his bike... It wasn't hard to do, requiring a paper clip, multi meter, and some patience...

I would have him tell me how to explain all of this in more detail lol but he is still sleepin'

Right now though, my R* runs extremely well, and I am of the school of thought "If it ain't broke, don't fix it"

I do enjoy reading all the write ups about how the AIS works and so on. Very educational.

From what I understand, the Warriors and Strykers have ECUs that can be flashed, but not the Roadstar.

Add this tid bit from Kai - The O2 Extensions wire is Part Number 99-0561. Cobra still sells that extension but its a direct order. $ 35.95. (You can use this when you install Freedom duals, but don't have to, just relocate the rear sensor wire to make it reach.)

Darn... oh well =) thank you for the part number for the extensions, though re-routing the wiring sounds easier. Someday, I will be looking at changing out my exhaust =)
