Re: Storage of BF90
For winter storage does manual says to drain fuel from carbs and fuel lines, change crankcase and tail oil, grease all sliding parts too ? If so, is a must do. With engine on fog fogging oil through carb intakes untill engine dies. If product is not availabe, 1-2 Oz will be sufficient per cylinder.
If lubbing manually, assume triming engine parallel than vertical will help to better distribute oil once poured in to coat pistons head and cylinder walls evenly while rotating engine electrically or with rope.
