Good question.  Well i guess im just going to get three new ones and just thread them in.  They came up just fine.  When i said they were welded in, i just ment they were very tight.  I could tell i was going to break something.

LOL. Heat almost always works at getting them unstuck. As long as you're patient and allow the hea and penetrant to do their thing, they will twist out. Get hamfisted though, and you've created a mess for yourself.

****BREAKING NEWS****

South Carolina man kills family dog with motorcycle brake.

Cal.. your abilities for welding are only exceeded by your skills as a writer.  Your imagination, I'll have to admit, is top notch.  You had me believing it right up to "Film at 11:00.  I realized this because it's video these days.

Very funny, dude!

Breaking news.....
I used air to release the stuck pistons in the front calipers.  Welded up a fitting to thread in the banjo bolt hole.   150 psi.  Didn't budge.

Added heat to the process.  Still didn't move.  I gently put a pair of pliers on the piston to wiggle it.  Had a block of hard wood in there for safey.  Wouldn't want to be unsafe! 

Pop.... pinned the piston to the block of wood.  Success!  Blead the pressure off. Removed the block and started adding the pressure slow, a litte more wigging and it came out with a hissss.  Second one went the same way.

No pets were harmed in the the process...cal.

Thanks for the support.  That's the third time in as many days I've heard that.  I'm starting to get a complex. 😩

I have pitting on my K3 forks too, I struggled with trying to save them but noticed the lower ends were very worn from poor fork oil maintenance. I gave up and ordered new tubes from Yamiya yesterday.
I don't think I'm ever going to add up the receipts for my project.
Your motor and frame look great. I hope mine turns out as well.
Aloha

MauiK3.... forget about the totals on parts.  Just think about how much the bill would be if you charged yourself for your labor. 

Were did yoi say you got new tubes from?

Yamiya, I've purchased a lot of stuff from them, quality is excellent, lots of NOS, things you can't find easily. Shipping is a little high from Japan but they are great. I try to consolidate shipments to lower shipping. They even have two really cool CB750 tshirts.
This is a labor of love so I try to ignore the cost.
They have very nice pre-painted tank and body sets, I got myself a candy blue-green set, paint is awesome.

Forking by Frank will supply you with better than stock chromed fork tubes.  Frank is super old school.  You call and send him a check with your order on paper and he ships your forks to you.  No internet or email ordering.

I went with the shorter Delkevic muffler for that reason. Picture is in the Reunion blog if interested. We gassed up the freshly installed Weber carbs through the 2 open fuel lines without installing the tank just to see if it would fire with the Webers. I didn't have it running enough to truely judge whether I like the sound or not. It is quieter than I expected after spoking with the Delkevic guy but that is an easy fix.  ;D Ofreen should be posting up a first firing video soon.
