that is a bittersweet way to acquire a motorcycle, you lost a good friend but Im sure he would be happy knowing you have his bike.
If its been sitting since October I would drain the fuel out of the tank before you start it up and ride it - put fresh gas in the tank.
10% ethanol fuel breaks down pretty quickly, unless a fuel stabilizer was put in the tank when the gas was fresh. Since he passed away unexpectedly his bike probably was not prep'd for storage.
People trying to start their bikes up in the spring when they were not properly stored is one of the biggest problems we see here every year. The gas breaks down and gets like jello / goo then clogs up the carbs or fuel injectors. Once the fuel is old there is nothing you can do to restore it, drain it out and get fresh gas.
Let us know if you have any issues.
If you are planning on picking the bike up and riding it home, the simple check is to look in the gas tank. If the gas is clear its probably ok. If it looks like coffee, tea or Pepsi, dont even try to start it up. The more you run bad gas thru the fuel system the more it plugs things up.
