This sounds like it should avoid some heartache I would like to steer clear of - thanksDefinitely disconnect the timed breather pipe union (at the bottom of the front cylinder by the magneto) and squirt some engine oil in there, turn the engine over a couple of times slowly while doing so. the breather sleeve is prone to siezing on the shaft (oil has drained out).
Plugs out, turn the engine over (push the bike around in gear) until oil returns at the tank (its a long process), this saves a lot of heartache, before a live start.
