Hi all.

After a top end rebuild/general clean & service I have a question about the oil pump.

I have read a few related threads on here including the recent one so I'm confident I have the oil pump/throttle set correctly.

I have done the following:

1. oil tanks were taken off and cleaned
2. Filled with Castrol Power which is green (the previous oil was red)
3. Bled pump by opening bleed bold until fresh green oil comes out.
4. Disconnect oil lines from the carbs and blanked off the inlets
5. Put some 30:1 premix in the tank and start the bike
6. Give it a heat cycle i.e. rev up to about 5000 until at operating temp (10 - 15 mins)

I expected to see the fresh green oil come out the oil lines within this time but not much came out at all.
Even by opening the oil pump manually all the way it only puts out a drip every 1.5 - 2 secs. It's still a kind of dirty brown colour which
I assume is the new oil mixed with the old.

So I guess the question is, is this normal? I'm kind of freaked out by how little oil the pump delivers and I'm scared to switch from the
premix until I'm sure its ok.

Also, am I right to keep running premix through until I see new green oil come out the oil lines?


Thanks in advance....

Al.
