BEC oil pumps
Anyone had any experience with two stage bike engine oil pumps.... well you never know!!!
Trying to work out why the ST1100 oil pump has two stages to it? Pressure stage is obvious but the scavenge stage has me stumped. The scavenge is at
the front of the pump which protrudes through into the clutch- I thought most bikes had wet clutches, can't think why you'ld want to put a
seperate pump to that area.... Looks like it's sump off and take it all apart time.... try and find out where the scavenge connects up to... It
might well be a passageway rather than the clutch....

I've got one (two infact, one for garage, one for home) but they're not helpful. They tell you its a two stage pump but not why and
frustratingly they don't show a picture with the pump removed....

The Yam Genesis oil pump used to have two rotors, one fed the engine and the other the oil cooler. Similar to your engine perhaps?

Honda engines are like that, the 2nd feed goes through the oil cooler.

Aha! Wondered about that. Which is good 'cos I'll be doing away with the cooler... Thanks,
