Got a bit inspired by your progress. Lucky you to find a prop stand.
So I took down the WD16H from the barn where it had slept for 5 years. Had to top up the battery as the horn was a bit weak. After draining sump, filling new oil and some air in the tyres, kicked it. It gently kicked back. Lowered ignition, next kick and it started. Running as smooth as ever. Will wait until the weekend riding it as weather should improve.
By the way any suggestion on how to fix the RD250LC suspension. Too soft front springs.
