It's mixed blessing. With engine in raw  aluminum you don't have to worry about paint chipping.

But I think I will go red on tank and covers to compensate for the black everywhere. Patriot red maybe.

Sometimes I feel I could go building forever - like Henri the painter in Cannery road. He was building a boat, but he was afraid of the sea - so he kept rebuilding and rebuilding:)

Honda Red would look good.  Yes, building can go on for a long time, especially if there's snow on the ground or you have another bike to ride.
I'm 2 months into a front end upgrade....no hurry.

But of course there is more urgent stuff to get done.  On top of  vineyard pruning and trellis repairs I have to deal with my jeep's transmission.

It is the 3rd on the cluster gear.  Looks like I will be able to replace it.

I found great SS clamps for carburetors.  They fit in the groove on the insulator and allow for more tightening than the original.

Looks like a clamp from a German vehicle. They work well

Thanks, Steve.

Technically Pamco and exhaust, but I want to finish it all before starting up.

Looking good Prokop. Not sure about your budget, but there is a sweet set of MotoGP Werks headers for a decent price on the for sale forum, might be worth checking out...

I am not there yet. I would like to reuse the exhaust I have in my stash - and get decent quiet mufflers for it. 

I think she needs 4-2.

The inside is not bad, I did electrolytic cleaning and it came out ok.

There was one pin hole on the bottom I had to solder up.  The biggest issue is the valve area,  it got bent a bit when i was removing really stuck petcock.  I am not sure if regular petcock ring will seal it.
