Assuming you’ve gone through the bike and everything is in order for the day, prepping your bike for the track is pretty straight forward.
Plastic and Glass – any clear or translucent plastic and glass needs to be covered with tape. If you fall off your bike, we want to keep as much of it in one piece as possible. That includes headlight, tail light, turn signal lenses, reflectors and mirrors (if you leave them on). I’d also recommend taping over your speedometer; it will only give you information that will slow you down.
Don’t tape your windshield or face shield unless you want to be escorted off the property and asked to never return. The blue painter’s tape works better than duct tape (it's not gooey and easier to remove), but duct tape can be used in pinch.
Lights – disconnect the headlight and brake light. The former will bake the tape on the headlight resulting in bad words later; the latter will distract riders behind you unnecessarily resulting in bad words now.
Tires – I’ll admit it, this subject makes my head bleed. The bottom line is it’s really difficult to get specific information about specific tires on specific models; I’ve asked. The tire manufacturers are afraid of getting sued, so they just don’t say anything. Grrrrr.
Anyway, here’s a general rule of thumb for a track day: street tire pressures are fine if you’re not riding crazy speeds. If you feel you must change your pressures, drop the front a few psi, and then set the rear at or just below the front. Make sure the tires are COLD when you do this. Also, if you do change the pressures, make sure you put them back before your next ride so you don’t ding a rim.
Bodywork – If you’re feeling particularly ambitious, unbolt anything you’d rather not replace if the unfortunate happens. This could include turn signals, mirrors, rear fenders, saddlebags, spousal units, etc. It’ll make the bike lighter, and let’s face it, you’re bike will look way cooler without that stuff. Track days are only once in a while; live a little.
