I have a Denso pump out of a CBR600F4i that I have been chasing around trying to find spec's to no avail. Denso doesn't list it as a replacement so no pump graphs/details. Price might be better that the KTM part, however this latest unit that PowerCell is showing looks promising.
PowerCell, what are the dimensions of the "cell" that contains the pump and bits?
there is a low lph Walbro out there too, might be interesting to pursue, however does not have the integrated pressure regulator.
