INJECTOR Cleaning made simple and works
I had posted elsewhere I picked up a 2009 AE with under 5k miles , Actually under 4k. It had idle issues and would die sometimes when cold and twisting throttle.. 1st thought throttle body sync. That did little to resolve anything. Then found 2 bad spark plug caps that could only have been damaged by servicing. _I did not cause this damage. Resolved the caps and this avoided the die issue. Thus it was only the injectors left. And since the tank and fuel hose are so easily disconnected I decided to disconnect fuel line at the rail, suck out the fuel from the rail using clean thin hose and mighty-vac. I then connected a 5/16( or can be done with 1/4") vinyl fuel rated hose to rail & then filled the hose with Berryman's and Techron mixture. Rail will only hold a couple oz. I disconnected the wires to the fuel pump. Then hit the starter button. This causes the injectors to open. Now the cleaning mixture has time to sit and clean. And if needed add more cleaner to hose. I then connected the wires , fuel hose to rail and hit the starter button. Obviously it will not start. Then on the 4th try it limps along. I did this series repeatedly 5 or so times, with mostly Berryman's and just a little of the techron. The 50psi fuel pushing on the mixture does the trick. I of course gassed it a few times to increase the EFI open time and to confirm the improvement. The Bike Now IDLES MOSTLY AS IT SHOULD . I can hear only a slight change in idle but so slight it does not show on the tach. Previously it made my cold AE not so smooth leaving a stop. No such issues now. And the drivability is wonderful. Don't bother throwing cleaner in your fuel supply, if you need a true cleaning, try this. ...cheers. Sorry for tilted pic.
I have other minor things. But I won't bother you for now.
