Yamaha, Husky and a Honda, all with EFI have all had an off idle stumble. These bikes all came from the factory extremely lean apparently to pass the EPA sniffer test. All have been easy fixes, the Honda an EJK, the Husky a spoofer and the Yamahan jumping the clutch switch to fool the ECU the bike was being started hence enriching the fueling. I suspect the RX-3 will have some type of fueling niggle with an equally simple fix. Perfomance wise I now will always pick an EFI over a carbed bike anyday.

If the EFI for the RX3 has a 'fueling niggle,' we will certainly appreciate some experienced input.

The Delphi MT05 ECU reports error codes to help diagnose EFI problems. See page 61 of the Delphi Small Engine EMS Service Manual.

Do we need to purchase the Delphi Motor Scanner, or will other scanners be able to access the error codes? Many Harley Davidson motorcycles employ Delphi EFI systems. Could we go to an HD dealer to have them read the error codes? If anyone can answer these questions, please do contribute your knowledge.
