Sorry if this has been asked before, I've tried 'Search' but i've so far only drawn blanks. Two queries.
Is the oil-pump from a CB650, fitable to a CB550F2 ?
And the same goes for the sump. I have seen this somewhere that this is possible, the proviso being it has to be a particular model CB650, and obviously the pick-up has to be modded to cater for the 650's deeper sump.
