Antifreeze and additive

[N0tac0p]

I am going to flush radiator. What if anything will help reduce heat?

The Valkyrie is not known for a weak cooling.
There must be a problem on yours.

1. Rebuild and clean radiator fins for maximum airflow.
2. Get rid of any aftermarket decorative laser cut radiator plate that restricts airflow. The bar type decoration grills are OK.
3. New regular water based aluminum friendly (silicate free) coolant. Avoid modern water free coolant because it has a 25% lesser thermal transport capability. The Anti corrosive feature is a tad better there if and only IF the whole system has been cleaned of any water first. A Valkyrie in good condition can live with the lesser cooling, though.

Best,

the engine is an all aluminum engine so it needs the heat that Honda designed it to have to function correctly, i.e. mpg, HP and mainly wear parameters. 180F water and below for all engines wear greatly accelerates.

install evans cooling once and be done.  did mine in '01, zero problems and no other changes required.

Just make sure it’s for Honda motorcycle engines. I’ve heard good things on the Evans product, my last bike I used engine ice. Used in race engines, safe for track use. So far no problems and is supposed to help it run a bit cooler.

I put Evans in all my liquid cooled vehicles years ago.  All bikes, the Kubota, the 4Runner.  Eliminates cooling maintenance and especially eliminates corrosion.  Watch the Jay Leno video on it, on youtube.  Here, I'll find it for you.  https://www.youtube.com/watch?v=t7PykrgzWPQ

I'm almost sold on Evans, But, If it does not cool as good as water based coolent, I'n not sure it will work on marginal, just good enough cooling systems.

where are u getting that from? 

the valkyrie cooling system is more than enough.

My thinking was to use it on all my water cooled bikes, but maybe I'll just try it on the Valkyrie.
The cooling system on my V65 Magna is adequate, but just barely. I would not want reduce its cooling capacity.

Valkyrie’s run hot by design. You’re basically sitting over a car engine. Unless the fan or pump stops working or you run out of fluid, I don’t know of one overheating.

Wow. That is a sobering analysis. 128 degree increase in temperature at the heads was enough to drive me away. Let alone the laundry list of other factors.

I was thinking of trying it, but will stick with what mother Honda designed.

Thanks for an interesting thread though.

So could be MC tire or CT. Maybe oil and filter thread.

Real world testing needed. Even coolant has been out 20 plus years.

My engineering instructor told me something I have never forgotten. What is on paper is only proven, if and when it works or fails out in the real world.

128F increase is bogus.  I've had evans installed for over 20 yrs. have autometer temp gauge saw about 5 degree increase in water temp. so basically she still runs within the tech manual parameters.
I agree with Avanti notice same thing while reading their FAQ. more sales pitch than anything else since antifreeze with their additive.

Will Evans make my engine run too hot?
No. People often think the temperature gauge reports engine temperature when it really is only reading the coolant temperature. With water-based antifreeze, the temperature gauge must be watched because when it gets too hot, the antifreeze will boil within the system allowing the engine to overheat. Evans Coolant will not create vapor; it remains in its liquid state, ensuring constant liquid-to-metal contact, maintaining its ability to draw heat from the engine keep metal temperatures under control.

[MarkT]

Again, I have installed Evans in all my liquid cooled vehicles and running them for years in all conditions.  Including my supercharged red bobber pictured below.  Haven't gone to the desert in summer yet - or 110° temps. In years past I have run such conditions in KS in July but that was before the Evans install.  In any case, what I have seen is normal behavior.  But now I don't have to do cooling maintenance.

What would be the best way to flush the coolant system to replace with engine ice

here is a review of waterwetter which is same product as ICE or any other additive for straight water

[sdv003]

I run HyperKuhl and a 25/75 coolant to water mix.  I live in the desert, so no chance of freezing.  Every once in a while I'll get the temp LED to sparkle, but the temp gauge says all is well.
