If you disconnect the hoses that go from the pump to the intake manifold it is recommended that you bleed the system prior to running the bike. There are two ways to do this.
1. Turning the pump by hand until oil comes out of the end of the pipes that connects to the manifold. Connect them and go.
2. Mixing up a small quantity of two stoke oil/fuel and, with the tank off, funnel it in to the fuel line and start the bike. Start the bike and while it is running open the pump to full rich until you see that there is extra smoke coming from both pipes. Keep it running for a few minutes to be sure.
In each case, make sure when you start the bike with the tank back on that there is smoke coming out of each cylinder.
Make sure you're using a good fully synthetic oil. I'm using Castrol TTS Power. 4 litres of fully synthetic for $70 is hard to beat!
