Hey all you FI guys and gals. What about posting everything you know about tuning, adjusting and repairing our fuel injection systems? We can start here, see what comes of it and them maybe transfer it to a tech article. I know very little, but am curious as to why mine has a slight stumble coming off of idle. So I'll start. Here's the little I know and some questions I have for others to answer:

* The stock ECU is not programmable. DK if it can be flashed by the dealer. Many have tried installing aftermarket ECUs (fuel processors) and many have eventually removed them because they couldn't get them to run right. Some folks have been successful.

* There is no petcock.
* The fuel pump is inside the gas tank.
* Is there a throttle body?
* Vacuum hoses?
* Is there an accelerator pump?
* O2 sensors?
* How to clean?

* Quote from Flyman1971 - He ran his bike with the stock ECU and duals for a week or so and decided on purchasing the Power Pro. He said the difference was unreal. A much quicker throttle response, alot more horses too, smoother acceleration, and a much cleaner burn! His machine was running too rich, now just a trail of water out the exhaust pipe. He did his research and all stock Roadstars run really lean, the black in the tailpipe is the tip. When he put the powerpro FI2000 on it ran a small stream of water out the exhaust now. This he is sure increased his fuel mileage by at least 15%. The Cobra PowerPro FI2000 costs around $550 and do not be fooled. They also have one for mid $200 range, but needs to be adjusted. I would pay the dif and get the one that programs itself 80 times per minute. He was weary on getting one because of the price, but he is glad now. Two of his buddies just ordered one as well after checking his out. You can install yourself within 45 minutes, very good step by step instructions. Good Luck and happy biking!

* Quote from Gadgetman728 - Look at both ends of the small rubber vacuum hose under the tank that goes to the injectors. Is the end that came off the intake end soft, swollen, spongy, split? If so, the rest of the FI guys need to know this. I recommended this easy mod, but no one wants to do it. It made a new bike out of mine. That sensor, to me anyway, seems VERY important, and a perfect vacuum signal seems needed. Good luck, it's easy.
