Weber-Marelli IAW fuel injection
on the Cagiva 900ie Elefant
The following pages are dedicated on the Weber-Marelli IAW fuel injection that is used on the 900ie and 900ie GT Elefants. Because information is scarce and widely spread on the internet, and also because I have noticed that even lots of motorbike shops have difficulties in serviceing this system, I have attempted to organise the information I have found and make it available via these pages. I hope it is a valuable reference for Elefant riders all over the world, especially for them who don't have access to specialists.
Although I have collected quite some useful information, is is by no means complete and there's also always the possibility that errors are present in the information. I hope all who visit these pages and have corrective or extra information (new part numbers, data sheets, schemes, adresses, etc.) will send this to me so we can all make this a complete reference point to keep our Elefants running.
Without naming any person in particular, so I won't forget anyone else, thanks to everybody that has helped gathering this info. Sometimes it comes from the most unexpected sources on the net.
