• GLEN HELEN OFFERS A $10,000 PRO PURSE FOR THE MAY 16 “STOPWATCH NATIONAL” WARM-UP RACE
Josh Mosiman talks to Bud Feldkamp, the owner of Glen Helen Raceway, about the upcoming “Stopwatch National” on Thursday, May 16th. Originally this was scheduled to be a one-lap timed challenge, but they decided to turn it into a two-moto race format, with 30-minute plus 1 lap motos for the 250 and 450 pros combined. They will pay the top ten, with the winner getting $4000 (which is what a 250 East/West Supercross rider gets for finishing second in an AMA Supercross and more than a fourth place rider gets in a 450 Supercross).
Also coming up on March 30 is the 2024 Wiseco World Two-Stroke Championship. It pays big money to the Pasha 125 Pro class, Pasha Over-30 125 Pro class and Pasha Over-50 125 Pro class (Pasha 125 Pro bikes can run 150cc engines). Of course, the stand-alone Open Pro class will be paying purse money also.

• POSTPONED! 2024 WORLD TWO-STROKE MOVE TO APRIL 19-20 
The Wiseco World Two-Stroke Championship was scheduled at Glen Helen Raceway for March 29-30, but due to a continuous string of West Coast rain storms, including a giant one scheduled to hit SoCal on the weekend, the race was rescheduled to April 19-20. Glen Helen only gets 5 inches of rain in drought years and 15 inches of rain on average, but this year it has been hit with rain storms virtually every week through January, February and March—resulting in 25 inches of rain falling in only three months

• MXA TEAM TESTED: TWIN AIR ICE FLOW RADIATOR CAP
Twin Air’s Ice Flow radiator cap increases the boiling point of the water in your bike’s radiator by increasing the amount of pressure inside the radiator. The difference between a stock radiator cap and a high-pressure one is dramatic. A motorcycle’s radiator cap is similar to the safety valve found on a chef’s pressure cooker. Since the boiling point of water increases when the water is placed under pressure, a radiator cap has a coil spring situated between two rubber seals. The stiffness of the spring determines how much pressure the water is under. As the water heats up, it expands. This expansion puts pressure on the radiator cap’s spring. When the radiator’s internal pressure exceeds the spring rate of the radiator cap, the hot coolant escapes and overflows between the two rubber seals. But, until the spring’s tension is overcome, the water will not boil.
Without any pressure on it, water will boil at 212 degrees Fahrenheit (at standard temperature and barometric pressure); however, a cooling system that is under 15 pounds of pressure will allow straight water to reach 250 degrees before it boils. For every pound of pressure exerted on the coolant, the static boiling point is raised by 3 degrees. (3) Measurement. There are many measurements of pressure. Most radiators use kilograms per centimeter squared (kg/cm2). American cars use pounds per square inch (psi). Scientists use kilopascals (kPa) and Europeans use barometric pressure (bar).
Most Japanese bikes come with 1.1 kg/mm2 radiator caps, while KTMs and Huskys come with 1.8 kg/mm2 caps. A 1.1 kg/mm2 cap can handle 14.22 psi before the coolant pushes the valve open and steam comes out the overflow. By increasing the radiator cap to 1.8 kg/mm2, the radiator can handle 25.6 psi, while a 2.0 kg/mm2 cap ups the ante to 28.45 pounds. The higher the pressure, the longer the water in your radiator will resist boiling. Twin Air offers 1.8 radiator caps to replace the stock 1.1 caps on Hondas, Yamahas, Kawasakis and Suzukis. For KTMs and Husqvarnas, which come stock with 1.8 caps, they have a 2.0 cap, which is 176 kPa, 1.96 bar and 28.45 psi.
DIGITS: $24.95— www.twinair.com or your local dealer.
MXA RATING: Water cools the delicate internals of your expensive engine. If the water boils, you will have an expensive aluminum doorstop on your hands. Luckily, there are simple spring-loaded devices that can stop your bike from puking.
