Incidentally, I can't prove it yet but I'm pretty sure Motorrad's impeller clearance mod knocked about 10 degrees off my water temps, perhaps more.
When I put the bike back together I didn't have any 50/50 green stuff that I was running in it before so I used Engine ice.
I'll know more as I data log temps and switch back to the green stuff.

Which mod?   Porting? Shimming? Big impeller?

Impeller clearance mod..
Add a extra washer behind the impeller... Decrease the impeller to cover clearance..

So, with the water pump clearance mod and enlarging the inlet side of the clutch cover, here is my temps for today.
70 deg F
42 percent humidity
Breaking in the new top end around town.
Highest head temp 204 deg F
Highest water temp 122 deg F

Average temps
Head 185 deg F
Water 115 deg F

Hmmm.... seems to big of a difference...
I'm taking it back to the shop to re-burp the head, rads, and impeller area just for insurance.

Here is as close as a comparison as I have recorded before:
Air temp 72F
Humidity 43%
Head: 158-162 F
Coolant: 133-138F

Very tool limited at the house but I pulled the burp plug on the left rad and B.U.R.P!!!!
Yeah, back to the shop tomorrow to burp the head, rad, and water pump impeller area..
I bet that will cause the two temps to come back in line..

Had a small clunking sound in the front end.
It was nothing more then a loose triple stem.
But the thing that I found that blew me away was all that dirt!!!  :D



I cleaned it up quick before someone saw it  8-)

Had a really hard time figuring out why my head temps were so much higher then my water temps since the top end replacement.
Also, I was getting a lot of spooge dripping from the head pipe area..
So Sunday I remove the exhaust and discovered that my cool custom muffler had collapsed internally...
I guess I'll have to do a bit of redesigning to fix it.
Now it all makes sense... hotter head temps and lots of spooge...
Gotta get this thing done and broke in before my next desert trip...
Since I can't run the custom muffler in the desert I bought a USFS spark arrestor.
Should be here Wednesday...
I sure hope so... I need to get going..

Me too.
I am going to add another temp gauge at the outlet of the head so I can see pre and post cooling... Cause Motorrad is making me.
