We haven't even talked about having to constantly monitor cylinder head temperature while riding.

Do you know something I don't? How are you constantly monitoring your cyl head temps while riding?
I know what temp these NE-5 s run.
The only accurate way to take the cyl head temperature, is while riding the bike in the wind @ 35mph
Trying to take the temp going any faster than 35 mph holding that temp gun, made me feel like I might crash
My testing NE-5
After 10 miles on a 82*F day, going 35 MPH in the wind and holding the temp gun 1' away from the cyl head, pointing the laser at a flat spot on the cyl head by the spark plug The temps were 300*F to 325*F which is acceptable for a flat head 4 stroke.
Case temp was 150*F to 175*F
But while at Idle within 3 minutes the cly head temps spiked past 400*F. Good thing stoplights are not longer than 3 minutes.
I don't use fancy heat coatings in the combustion chamber either. (A rumor was started that Whizzers needed heat coatings)
The Rumor claimed that the temp of a Whizzer was over 500*F and a combustion chamber heat coatings reduced the temp to 300*F
If it makes ya feel better and have more confidence in your Whizzer than use heat coatings They can't hurt and just might do some good too. But I find them not necessary on the NE-5
I've got over 39K miles on my Whizzer. I won't hesitate to take my Whizzer on a 100 mile ride. She's always ready
I even rode my Whizzer in over 100*F heat all summer on purpose just to see if I could melt her down. Nope, she was just fine
I must be doing something right
I run a NE-5 Cast Iron Westman Cyl and an Ambassador Head shaved 150"th
The Ambassador head is nicknamed "The Block Head" because of the short cooling fins
My bike's top speed is 50mph and I cruise at 35 to 45mph and I don't have a heat problem.
You would think I would have a heat problem with a cast Iron cyl and a cyl head with short cooling fins
I do resurface the head every 1K miles and use a new copper head gasket if needed
I make my own head gaskets, last time I made some I made enough for a life time.
Howzit Everyone, Making your own Copper Head Gaskets saves a lot of money$ and now you can match the combustion chamber exact. Cutting and drilling thin copper sheet takes some thought and skill. I'll explain in order what works for me and the basic tools I use. I use .016 th" thick copper sheet...

Sure the Whizzer needs the right mods and routine maintenance.
Anyone with mechanical aptitude can learn how to work on them.
The key to keeping your temps down is don't idle for long periods of time and stay In The Wind
You should be able to ride your NE-5 all day if ya want.
If ya really want to keep the temps down, ride the bike @ 25 - 30 mph, But that's no Fun
Don't even play with a WC-1 Upgrade the Cyl to a NE-5 (Today it's the Cruzzer Cyl kit)
