shopping list eh Gorby..jeez where to start! so many projects so little time
the TS90 I'm now thinking I should try and go back to patina original. Not an over the top resto but tidy all the same so yup, battery box, headlight/tail light, speedo and chain guard are the main items as the 70 model never had blinkers to bother about. Thinking I should maybe try and hunt up a nos wiring harness as most by now have been hacked and chopped, if you have a goody though I'd glady accept that as well
this time I 'insist' on payment ok, the yz plastics you sent were spot on btw, the little XR/YZ isn't far off being rideable
CG that carb you have is probably from the '76 which is different. I think they are a push in type spigot mount which would require some work to fit. The square bit at the top is nothing to be overly concerned about and doesn't cause any problem except you need the right cable.
