WR500 questions first timer

Hi,

I have a few questions about my Yamaha WR500 that i want to get up and running and i was wondering if anyone would be kind enough to answer these questions?

• What sort of oil do i need, is the mix 25:1?
• Is it safe to start out of the water?

I have just checked the whole thing over and everything seems to be in tact.
I just wanted to confirm the above before i try to start it, just incase i make it go bang!
