Get a water temp gauge on it for insurance.
I'd also do a head temp gauge but I like lots of things to look at while I'm riding.. :-o
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

That’s good advice. I’m probably going to do a Trail Tech Vapor like on Goliath. I like having the engine vitals handy.
Perhaps I have a dirt bike addiction?

Have you seen the new trail tech Voyager Pro?  A little pricey but awesome. I just put one on my 500. I need to get a tap so that I can install the coolant temp sensor into the head though.

I actually have an original Voyager that was on my KX/KDX hybrid.  I like the Vapor's tach read out, but the Voyager is way cheaper.  I really need to catalog my parts bin.   :-D

Brett at ICW got my radiators turned around in a hurry.  I should have them tomorrow, and will post pictures of what we came up with.  After the radiators, I just need to finalize the headstay and I'm ready to ride.  I can't believe I nearing the end of this project.   :-o

I forgot to mention that the suspension is finally done.  Sandblaster referred me to Oscar Cota (USMC 500), who referred me to N2Dirt Suspension and Brian Bolding.  I was originally going to do Ohlins TTX suspension, but Brian has had some bad luck with them and is having a hard time getting parts to fix the issues.  He suggested a different solution, which involves a conversion to the front forks and extensive work to the rear shock.  I'm going to leave you with a bit of cliff hanger because I don't have pictures of the forks, and everything comes in on Monday.  For now, here is the shock.  It's a heavily modified 2017 KX250F shock with Kashima coating on the body and DLC on the shock shaft.  I can't wait to see it in person.

Ok,,, I tried to get the Kashima coating and it was absurdly expensive..
They wanted me to send it to Japan.... NO....
How did you get it done and what does it cost?

I’m pretty jealous of your KTM build. I’m just trying to keep up.  :-D

Dear MXA test riders used to riding stupid, boring four strokes,

A bit of advice before riding Sandblaster's bike...

I had one of those really great days in the shop today.  I tackled a number of nagging issues, and was able to solve them all.  It felt a little like a blind squirrel finding a nut, but I'll take it.

I got my radiators in from ICW on Friday.  Brett turned them around in less than a week, and the work is really nice.  If you need some radiator work, he is very easy to work with.  I attached a picture of them both.

I was able to make the two stroke radiators work by raising the tanks 1" and having Brett modify the tanks.  The second picture is the brackets I made out of 1/8" x 1" aluminum strap.  I used thread inserts and rivnuts to attach the radiators to the brackets. 

I have never seen my bike together as a four stroke, so I don't know how the four stroke radiator braces work, but the tab on the frame is at a seriously weird angle.  I was able to make a series of bends in some aluminum strap to tie the two stroke radiators to the frame.  They feel very secure.  All I need to do now is to get the transfer hoses cut and installed, and lengthen the top hose and I should be done with radiators.

I got a really good start on my head stay.  It has been a nagging concern of mine, because there is no where to tie on the the frame like the two strokes are done.  I came up with a 3/16" steel, very stout bridge that uses the stock two stroke head stays to the cylinder head, and ties in to the frame where the four stroke head stays mount.  Most importantly it is above the level of the cylinder head so that it can control forward motion.  It's still very ugly, so I didn't get a picture yet.  I'll be finishing up some reinforcements and cleaning it up next weekend, so I'll get some pictures then. 

The suspension comes in tomorrow, so I should have some rolling pictures for you guys very soon.  I should have it done about the time it gets stupid hot around here.   :-D
