Overview
IMPORTANT NOTE: THESE ARE SOLD IN PAIRS
Matched injectors for early-to-mid EFI Ducati Monsters using brown IWP PICO injectors.
These are purchased from the factory as "matched pairs" within a very narrow specification. We then take these and re-test them in-house and re-group the injectors while considering their flow values at narrow, middle, and wide pulse-widths, with emphasis in that order. This gives our matched injectors superior performance at partial throttle as well as WOT conditions!
Replaces Ducati OE 280.4.015.1A & 280.4.007.1A
In depth: In another industry first, California Cycleworks is
taking things to another level! Most specialists selling fuel injectors
sell “matched” sets. While researching injectors' performance (both OEM
and from aftermarket factories), we saw that the automotive industry has
little concern about injectors' relative performance.
Injectors are spec'd by GPH, LPH, or CC/min with the injector simply
turned on. In real life, no injectors are simply turned on and left on.
Injectors with the same specification would have up to 20% variation of
flow at narrow pulse-widths, such as at idle and barely-open throttle
positions!
We found a factory willing to sell us injectors in “matched pairs”
within a very narrow specification. We then take these and re-test them
in-house and re-group the injectors while considering their flow values
at narrow, middle, and wide pulse-widths, with emphasis in that order.
This gives our matched injectors superior performance at partial
throttle as well as WOT conditions.
Installed on a typical two-valve air cooled Ducati with slightly
too-rich running conditions, these injectors bring a welcome and
unexpected smoothness to throttle delivery. Our testers were surprised
at the affect this has on otherwise normal bikes. Overall flow values
will vary from bike to bike and also from one of our matched pairs to
another. At the very least, access to adjusting trim is considered a
minimum requirement for installing these injectors. Ideally, these would
be part of a careful air-fuel ratio test and calibration of the fuel
system, such as done by a dyno tuning center.
