Used Weber / Magneti Marelli PICO fuel injector - IWP189 with violet band 12 hole 'cone shaped' spray pattern for perfect atomisation when used as a 'shower' injector high up in the air intake stream Standard equipment on all these Ducati bikes 848 1098 1098R (high flow injector) 1198 S4RS -later models Streetfighter Superb upgrade option for 749 or 999 which use the single stream yellow injectors, but will need some re-mapping. The cheapest I could find them online/ebay is 110 gbp a piece. 110 gbp for both + shipping 7,50 (UK) Pictures of the actual items.
I have a pair of these fitted to my 748RS engined track bike and ran them for a while on my 748R and they work a treat. Don't expect good mpg but do expect to liberate a few more hp and torque. You will need a power commander or map though. Andy
