Solution for the cooling problems of the 954

I do not track my bike and I never will track my bike. Just because it has been outlawed at racetracks through rule book changes doesn't mean it is an inferior setup or bad for a machine.

This is an excelant modification for street use bikes. I did a write up on this and posted the install in the Fireblade section. It will run at lower temperatures then a 50/50 antifreeze set up with a 0psi radiator cap. It will not freeze or corode your engine from the inside out.

The major benifit that I see besides raising the coolants boiling point to 375 degrees (a temp much higher then anything we will ever see) is that a 0psi cap adds no artificial pressure on your radiator, hoses, seals, and gaskets that is scene with the stock 15psi radiator cap. The only pressure is the water pump circulation, thus extending the service life of all of the components of your coolant system.

True Dat! Except as Abtech stated. My point was only that if the user plans on putting the bike on a racetrack he may have problems with teching the bike.

Good install write-up by the way.

NPG+
Evans NPG+ Waterless Coolant is the recommended coolant for all gasoline and diesel engines. NPG+ is a stand-alone lifetime coolant that does not freeze, or boil over. NPG+ controls detonation, cavitation, and is non-corrosive. Installing NPG+ requires the radiator, engine block and heater core to be drained completely and then filled 100% with NPG+. NPG+ meets or exceeds both the ASTM D 1384 corrosion test and the ASTM D 3306-94 specifications.
Boils 375°F @ 0 psi
Freezes -40°F
Viscosity 2.3cp @ 212°F

NPG-R is specifically formulated to handle the extreme conditions of racing and high performance automotive, marine and motorcycle applications. The reduced viscosity of NPG-R makes it more compatible with small tube copper-brass radiators while providing the superior cooling of Evans Waterless Coolants. Although NPG-R is safe for all metals and contains no water, an annual coolant change is suggested for racing vehicles. For maximum corrosion protection, high performance street driven vehicles running NPG-R should change coolant every other year.

Evans NPG Waterless Coolant is the original waterless coolant. NPG is only recommended for racing engines that run on tracks or in series that have a “no ethylene glycol’ rule. NPG is also a stand-alone coolant. To convert to NPG the radiator, engine block and heater core must be drained completely. NPG is not recommended for daily drivers or cold weather vehicles.

Can You use the reg NPG at the track?

No. Even though they state it is designed for racetrack use, independent testing has shown it to be several orders of magnitude more slippery than water on asphalt and concrete. Some trackday companies allow it, but most racing organizations do not for the above stated reason.

Correct, but this is not a track only website.

This type of coolant, although superior to any other, was outlawed in racing because of your above mentioned details.

Please reference parts of this page:

Motorcycle Gallery - Page 1 -

This is splitting hairs on the matter though.

Most street riders do not have (hopefully not that is) the problem with wrecks that is a constant threat to safty on the track.

You wouldn't want to run evans on the track for the same reason you wouldn't want to run racetrack tires on the street.

That is correct. While this certainly is not a "track only" website, I have had to answer the same question numerous times during the past 5 years regarding this subject and the Fireblades.org event at Grattan.

FYI, I have had to sit and wait over 2 hours while the track crew cleaned up the slick left ontrack by a crashed bike running Evans "racing" coolant. It probably would have gone much faster if three other bikes hadn't crashed while sliding on the slippery track and leaving parts all over the place.

I'll bet these 3 riders weren't overly impressed by this type of "superior" coolant when assesing the damage to their equipment . . .

I believe the higher operating temperate actually has to do with the fan operation to conserve the battery.

Water not under pressure has a boiling point of 212F

Water under pressure has a higher boiling point then water not under pressure.

I can't look it up now but at 15 psi (stock radiator cap pressure) strait water has a boiling point in the high 240ish low 250ish F range.

A 50/50 antifreeze water mixture at 15 psi boils somewhere around 264F.

It seems that theres a miss conception about boiling point of water/antifreeze. Water boils at 212 deg F.

Two things increase the boiling point of water:
1. By adding ethylene glycol (Antifreeze) to the water

It seems that theres a miss conception about boiling point of water/antifreeze. Water boils at 212 deg F.

Two things increase the boiling point of water:
1. By adding ethylene glycol (Antifreeze) to the water
2. Pressurizing the water/coolant within a sealed system

By running a 0psi radiator cap you are actually keeping the boiling point of water or water/antifreeze mix at the normal boiling point. By pressuizing the sytem you are raising the boiling point. Thats way ALL vehicles and motorcycles come with pressure caps.

Here is a quick explanation of fluid/cooling system and boiling I found that might help.

This is correct. The boiling point of a stock system on a 15psi cap with a 50/50 mix is somewhere around 263F.

Cutting the cap on a stock system will only result in an overheated bike.

If you are directing this comment to me then you have misread my post. I do not run a water based coolant system in my 954. I run a waterless oil based propylene glycol coolant which boils at 375F without pressurization. I now have a little over 2K miles on the clock while running Evans at 0psi.

has anyone tried a supplemental fan or changing the fan temp sensor to activate the fan at a lower temp?

There seems to be a misconception about how engines run. They breath air. In many parts of the world air has water in it. We call that humidity. That water can condense and corrode engine parts from the inside. Thus 220 degrees is a damn good temperature at which to run your engine.

Airplanes have aluminum engines. I actually have to block off the oil induction system on my Cherokee in cold weather to keep the oil temperature up around 220 degrees.

after two blown head gaskets, i'd tend to differ in my opinion.
