There's a silicone gasket for the mag cover... I've also used spray can shellac to coat/soak the gasket make sure it's dry or it will come off hard.. use Yamaha bond 3 on the case half's after sanding flat on a piece of glass and adjust the shims and sometimes ream the jug holes (depends) will pull the case together some use acetone on the surface..any oil on the surface will cause a leak over time and wick... Indian head gasket shellac and some toothpicks is your best friend on the cardboard intake gasket but will be a pain to get off... Friction tape for hockey sticks is good for where cables rub
