Heat is the enemy of dirt bike and ATV performance, but simple steps can be taken with CV4 thermal protection products to avoid running into bigger problems. Radiator Hoses Not all radiator hoses are created equally. This is never more apparent than when your bike’s hose tears, cracks, leaks or collapses. Odds are, your bike is equipped with old-fashioned OEM rubber hoses, which do a menial job. Chances are, your bike still has OEM rubber hoses, which can crack, tear, and deteriorate. Reliable hoses are a key component in protecting your engine against the dangers of overheating. Fortunately, advancements have been made in radiator hose technology. Silicone is the new go-to material for hose construction. CV4 has taken it a step farther by utilizing the highest-grade silicone material available. Not only does it improve heat and abrasion resistance, but it also makes assembly and disassembly much easier. When you’re dealing with coolant temperatures around 300 degrees Fahrenheit and extreme pressures, it’s peace of mind knowing that the radiator hoses will hold up. CV4 radiator hoses are made of the highest-grade silicone, providing consistent performance and protection through countless pressure and temperature cycles. CV4 is available directly from Wiseco. Want to find radiator hoses for your machine? Call Wiseco today at 1-800-321-1364 Over 2,000 years ago, Greek mathematician Archimedes stated, “The shortest distance between two points is a straight line.” He wasn’t talking about radiator hoses, but the rule still applies. CV4 offers their hose kits in standard and Y-kit configurations. The latter has joints formed into the hoses, which reduces the number of fittings and clamps necessary. Less turns and twists for the coolant to navigate results in improved coolant flow and efficiency. Not only that, the ‘Y’ design helps protect against leaks. Note that the Y-style hose kit costs slightly more than the standard design. Y-kits from CV4 have joints and intersections molded into them where OEM designs would normally have metal joints and hose clamps. This helps reduce chances of clamp failure and coolant leakage while improving coolant flow. Don’t wait until your radiator hoses start leaking or collapsing. Father Time always wins, and your OEM radiator hoses are not exempt. It’s important to also understand that when one hose gives up the ghost, the others aren’t far behind. Improve the performance of your bike with a CV4 silicone radiator hose kit. While you’re at it, pick up a new pack of CV4 radiator hose clamps. They are specifically designed for radiator hoses, clamping the hose efficiently without digging into and tearing the hose material like some standard clamps. See the CV4 products overview on Wiseco's site here. Many OE style clamps will tear into hoses and compromise their integrity. CV4 hose clamps are designed specifically for radiator hoses and allow for repeated assembly and removal without causing damage. High Pressure Radiator Caps Most riders don’t understand the importance of a radiator cap. They remove it every so often to check the coolant level before riding, but otherwise don’t give it much thought. From a design standpoint, a radiator cap is a thing of beauty. Under the cap is a coil spring located between two rubber seals. You don’t have to be Bill Nye “The Science Guy” to understand that water, or coolant, expands as it heats up. That creates pressure inside the radiator. The radiator cap’s job is to keep coolant in the radiator and flowing throughout the cooling system. If there’s too much pressure, the fluid will force the coil spring into the cap. When that happens, incredibly hot coolant will find its way out the overflow hole between the rubber seals and end up on the ground. When the pressure rating for a radiator cap is exceeded, coolant will flow out of the overflow, lowering pressure and coolant boiling point. CV4 caps aim to avoid this. While this is designed to protect cooling system components from excess pressure, lower pressure in the system also means a lower boiling point. The key is to find the happy medium between pressure and boiling point. The CV4 radiator caps are equipped with a stiffer spring rated to withstand a higher pressure (but not high enough to cause damage), meaning the boiling point of the coolant in your cooling system will be higher. A higher boiling point is key for efficient cooling, as boiling coolant is not effective in reducing operating temperatures. With a CV4 high pressure radiator cap, the coolant stays where it’s supposed to–in the bike. This is inexpensive insurance for your cooling system. A radiator cap rated to withstand higher pressure helps protect your coolant from boiling and allows the cooling system to continue efficiently managing the temperature of your engine through a wide range of conditions. Thermal Barrier Film Not all performance can be seen. Case in point, many of the world’s top race teams rely on thermal barrier film to keep their fuel cool. Typically applied to the underside of the fuel tank, as well as around the fuel lines, the film resists heat that is given off from the engine. Sometimes problems out of sight can do the most damage. CV4 thermal barrier film is commonly applied to fuel tanks and fuel line to prevent fuel boil. Maintaining cool fuel temperature is especially important during the hot summer months and/or when riding at higher elevations when the boiling point decreases. Either factor will cause your bike’s fuel to lose its combustibility, which has detrimental effects on engine performance. Fortunately, CV4 literally has your bike covered. Choose between two heat resistance ratings. The silver film protects against highly elevated temperatures that reach up to 1200 degrees Fahrenheit. The gold film protects against temperatures up to 800 degrees Fahrenheit, with the added benefit of reducing temperatures by up to 36 percent. Simply cut out the film in whatever desired pattern you choose and stick it wherever heat is a problem. CV4 thermal barrier film is offered at two levels. Silver protects against up to 1200°F and gold protects against up to 800°F, achieving up to a 36% temperature reduction. Temperature Strips It would be nice if your bike could verbally communicate with you when it’s having a mechanical issue. Fortunately, there are ways to diagnose the problem. Performance changes, weird sounds, odd smells, steam and blue smoke are indicators that something is amiss. Before ever getting to that point, it’s smart to monitor heat emitted by the engine, radiators, shock body, and other vital areas. CV4 adhesive-back temperature strips are the solution. CV4 thermostrips can monitor temperature just about anywhere you can stick them. Here, Geico Honda uses one on the left-side radiator of each of their race bikes. Available in a three pack, they are designed with incremental temperature monitoring sections that change color once that temperature is reached. Each strip shows a temperature reading from 149 degrees to 248 degrees Fahrenheit. Installation is easy. Thoroughly clean the desired mounting surface, peel the adhesive backing off, and stick wherever desired. You’ll get an accurate reading every time. Stick 'em on and the color will change when that temperature is reached. Simple and cheap protection for your expensive machine! Universal Vent Line Kits Chemicals, fuel, time and environmental factors are the chief culprits for vent line destruction. For these reasons you may notice that the vent lines on your carburetor, gas cap, radiator overflow, and/or water bypass lines crack or break. Vent lines are important for proper operation, which is why these oft overlooked items shouldn’t be ignored. CV4 saves the day with their universal vent line kit, which fits a wide range of different model bikes. Made from pure silicone and available in a plethora of popular colors, the line kits are highly flexible for easy installation and removal. What’s most impressive is how the vent line kits are rated to withstand temperatures up to 420 degrees Fahrenheit. That’s a lot of heat! Please note that the vent kits are not designed to replace fuel supply lines. Simple things like vent line can be overlooked after extended periods of time and end up hardening and cracking, causing annoying issues. CV4 vent line helps keep the simple stuff handled, plus, makes it look good.
