Good start is the sweet PDF @sark put together. Maintenance guide may give you some ideas.
Sark's HZJ73 Adventures - https://forum.ih8mud.com/threads/sarks-hzj73-adventures.1276682/post-15420886
6 full days since a WDYD post? I'll go.
Just DD this thing sans FRP while we still have sun.
half doors made a big difference in exhaust smells. Still get all the other outside smells but less my exhaust smells.
Tossed a Hallman manual boost controller on the 77 over the weekend. Seems like a nice unit but still need to play around with it.
Upcycled a bracket to have it stand-off Tor's air filter box a bit. Only place I could fit it and still be able to easily adjust.
