Maybe not the most organized way to do it but I tackle my projects from all sides at once. Too often I am waiting for parts, inspiration or I cannot find the right parts.My first plan was to tackle the triple bypass on the engine (since it's out).
Then for example your bypass work is on hold for 3 weeks. Then something small happens like your gear shift spring is stretched beyond use and you have to order one, more waiting etc.
There will be enough small things to do like , checking your head bearings. Inspect wheel bearings. Clean brake system. Clean Carburetors, Clean fuel tank.
All these small things accomplished gives me a good feeling that my project is not at a standstill
