What do I have to do to prep my bike to race SuperMoto?

Remove the coolant from your bike’s motor. (mandated by the race tracks) You need to replace the coolant with distilled water. There is a product made be Redline called “water wetter” that you can get at just about any shop, that you add to the water. This acts as a lubricant for the water pump, and reduces the friction in your cooling system, which keeps the engine temperature down.

To prevent fluid from leaking onto the track and causing accidents, you will be required to place a dab of silicone or “gorilla snot” on each bolt that has fluid behind it. (oil drain bolt, oil filler cap, water pump drain plug, etc.) Safety wiring these bolts is the preferred method, but is not mandatory. To safety wire a bolt, you must drill a hole through the head. You then run safety wire through the head of the bolt and around something else that is stationary on your bike. It is very important to make sure that the safety wire is pulling toward the right side of the bolt, as this will keep the bolt from backing out. The purpose of using the silicone or safety wire on these bolts is to ensure that your bolts don’t back out due to vibration and leak fluid onto the track. Below are a couple of photos that have been taken of safety wiring the oil drain plug, oil lines, and the oil filter cover. The oil filter cover has been wired in a “daisy chain” manner, which links all three bolts together in a continuous manner. This puts continuous pressure on the right side of each bolt, so that they do not back out. The other two bolts that hold the oil lines on are both wired together with each pulling the other to the right to keep the bolts tight.
