What a neat rebuild!
I am curious to know what the oil tank looks like and where it goes.

I don't have pics at hand of the whole tank but you can see it here, it sits on the right hand side of the frame underneath the fuel tank.

And here is the oil pump just below the intake with a hose running to the inlet manifold.

In the bottom pic? That is the idle adjustment on the PE28 carby, quite convenient but not necessary.

OK, yet another tidbit we didn't see in the USA.

1fletch, welcome to kdxrider.net. Start a new thread and a few of us can help you out some. I have had some apart and rebuilt them before more than once.

I'm a bit behind on progress so here's an update.
After the engine went back in it was looking good, break in went well and it pulls hard, lots of fun.

Then I decided I wanted to swap to the bigger (standard) carb on the E model from the 28mm SR one, so started sourcing parts.

The SR has an oil injection port on its inlet rubber and the replacement one does not.

Next up was the valve, I filed a spare down using a drill and can now insert it inline before the carb.

Hey that's some great work! I like that clear float bowl!

i found that float bowl on ebay, doesn't look like it has a provision for any sort of overflow tube, or a removable bowl plug. If your float ever sticks open, it'll likely fill your crankcase with fuel before it comes out of the breather hoses on the carb.

Yeah it's not the best design, unfortunately my original metal bowl will do the same due to a previous owners handiwork :(
