Sitting a long time, first steps

[unclebucky47]

Hi guys,

Just picked up a 1976 RE5.  By the layers of dust, it has been in the barn a long time.  I removed the plug, added Marvel mystery oil, let it sit for a day, kick-it over slightly, added more marvel mystery oil---I have also removed the old dead battery.  The tank was off the bike and the petcock removed (both in good shape).  I sprayed some carb cleaner into the carb, it ran out clear.  The carb drain bolts/screws were loose, so I think the previous owner drained the carb at storage as well.  

Before trying to start this beast, what should I do?

1.  Clean the carb?  Off the bike?  Scary!

2. Install  the tank/petcock & fresh fuel, i think that's a given.

3.  Change the oil?  What brand/weight?

4.  I have a brand new plug.  Came with the sale

5.  New battery, I have one ordered.

What Else?

thanks to all, Bucky

20-w50 ash free oil.
Suzuki recommended at the time Castrol GTX that is now available sold as Castol”Classic “
There are other oils available just make sure it burns “ash free”
Replace coolant and check pipes for hardness and cracking.
Clean and check points and static timing .
Clean carb and blow dry with compessed air through as all galleries with jets out.
Turn engine over without plug until you have oil pressure.
I would compression test if you have tester before you fire up. If thats OK.
I would start on pre mix 50-1 untill you are certain that metering pump is working.
