Posted updated checklist [V6]
Progress today
Pulled stripped fork bottom bolt from right fork leg with fluted screw extractor (EX3 size). Very tight, apparently seized. Started to bend the tap handle, so switched to crescent wrench. Scary and slow, and the extractor twisted a little sideways, but finally pulled it.
Attempted to fit new seal and upper bush in left leg. Green seal driver did not work, at least not well. Need better clamp and maybe thicker plastic tube/pipe. Also I caused inner (threaded) part of damper assembly to ride up so lower bolt wouldn’t reach. So …
Completed disassembly of left fork leg.
Then able to push inner damper down to end.
Cleaned parts. Left leg ready for reassembly. Also enables more thorough oil fill/measure routine.
Drained coolant at water pump. It was surprisingly green as opposed to brown and rusty. Hope that means it did a good job preserving internals.
Disconnected both radiator hoses and pivoted radiator up to access front spark plug holes. Replaced spark plugs in all 4 cylinders.
Reassembled radiator hoses and installed radiator bracket (apparently off for years – bolt partway in hole).
