    Even more fun, is it Engine Ice that when it boils the gas if flammable?

    I've ran Engine Ice in my street bikes for many years with great results. Fans rarely come on and that is in the heat of summer down here in the SE. Very happy with results.

    I guess I'll be the first one to say it: sounds like you need a new bike. At the very least you need to upgrade to a clapped out 2003 SV650 to prevent overheating.

    Double check your radiator and make sure all the fins are straight. A year or two racing especially anywhere semi sandy will bend them enough to restrict the air flow. They won't look super bent but a little is enough to matter.

    The additives do help some by reducing the bubbles at the metal bits. Also helps by being a bit of a lubricant.

    hmmmm. Bubbles forming and moving off the metal actually help quite a bit. It's called nucleate boiling. The phase change absorbs a lot of energy, over 1000 BTU's per lbmass. The real problem is if temperatures go higher due to increased heat load you reach DNBR, departure from nucleate boiling or film boiling. At this point temperature of the heat exchanger surface rapidly increase and the heat transfer rate suffers. Best to stay below the boiling point. I'll add that when the bubble collapses after leaving the surface that 1000 btu's had to go somewhere....where it goes is into raising the the temperature of the surrounding colder water....no free lunch.:mad:

    PS, I'm not disagreeing, Mongo...just elaborating.

    Makes sense, but the whole point is for that heat to go somewhere other than stay in the cylinder walls. So if it transfers to the water the water can then move it to the radiator and get it out of the system more efficiently than it not transferring anywhere. Less bubbles means cooler metal temps or at least more efficient cooling of the metal and that is the entire point of the system.

    most streetbikes come mixed on the rich side with glycol. So simply changing to a prediluted mix like EI will promote a cooler running bike. You can do the same with standard glycol... just lean the mix some. Trackbikes just need more frequent service on the coolant and no glycol.

    Yep, or just check the cap you have. They do go bad more often than people may think. One more thing, pull and check the pump for signs of cavitation. High rpm engines can suffer this issue. Checking the pump should be a regular maintenance deal on a race engine.

    More on cavitation, etc...
