In the interest of not having repetitive discussions, this thread is to document a not-uncommon situation when changing the oil on 2004 through 2010 model year ZX10R's.

The issue is that if the oil pump is left "dry" on both sides (i.e. you have the filter removed and you have the sump drained at the same time), oil will siphon out of the oil pump, leading to an air-lock and no oil pressure upon restarting the engine. It only happens occasionally.

The situation can be largely avoided by first draining the oil then refilling it, THEN changing the oil filter.

Other suggestions include partially filling the oil filter before re-installing it but I would suggest doing this in addition to doing the oil change first and then the filter change.

If you change the oil and the oil pressure warning lamp remains on (or flashes) for more than 3 seconds after restarting the engine:

1. Turn the engine OFF!

2. Position a drain pan underneath the oil filter.

3. Loosen the oil filter slightly (1 or 2 turns) so that it is slightly clear of the seal.

4. With your finger on the engine-stop switch, crank the engine a couple of revolutions - if it tries to start, stop it immediately.

5. Check whether oil is coming out from under the base of the oil filter - this indicates that the oil pump is now pumping. If it is not, repeat steps 4 and 5.

6. Tighten the oil filter securely.
