Some more work done. Plumbed in the oil cooler, installed carbs. I bought the carbs from Wired George awhile ago when he was selling his O Bored VM26's. They are now 30mm but look stock. They have been sitting in a box on my shelf for years , nice to finally bolt them onto a bike.

The bike came with a brand new Vance & Hines pipe. I had the header ceramic coated in silver and the slipon in satin black.

Stock 26 or 28's bored to 30mm perform better than 29 smoothies and are easier to set up.
They will make a difference even on a stock motor just like going up from 26 to 28.
It's a fairly simple job if you have an accurate lathe.
Here's a pic of some I recently did.
The top set are stock 26's and the bottom set are bored out.

It's a performance solution that still looks stock without having to pony up for crazy expensive 29mm smoothbores that are more complicated and harder to tune. I've installed a bunch of these bored carbs back in the day and they all improved overall performance. And yes the head is ported along with bigger high comp pistons and more aggressive cams.
Hardrockminer your way over thinking this .

Centered the rear wheel in the swingarm and aligned and installed the 530 chain.
Finished up the wiring, installed the coil relay mod and put on the restored gauges.
