From: Steve Lusardi on 10 Jun 2010 01:28 Never use nitrogen in motorcycle tires.....ever. This is critical. Tire heat is essential for maximum traction. Bike tires filled with nitrogen stay too cold. I have followed this thread and like most of you, have found some of the statements made by the originator a bit short of credible. First, unless this fellow weighs 400 lbs, the suspension won't bottom out on any setting. Nobody has asked how heavy this guy is. Setting up a suspension preload is stupid simple. Most of the readers here know how to do this, so I won't bore the readers with these directions. They can be found all over the net and in his owner's handbook. He needs to use the tire manufacturer's pressure range period. I am relatively certain the guys that made his tires know considerably more than he does about his tires. Please keep in mind his tires performance is almost as important as the space between his ears in preventing a really bad day. I suggest he owns the wrong bike. Sportbikes are not mile eaters. They are performance machines. if he wants a mile eater, he should buy one. These are two completely different roles that cannot be performed by the same machine. I have a Road King, a street legal Buell 1125r and a race only 1125rr just for that reason.

The reason for using nitrogen to inflate tires is that it is a *dry* gas and the pressure won't increase so much due to the vaporization of *water* when the tires get *really* hot. The first time I ever saw nitrogen used to inflate tires was in an aircraft tire shop. Aircraft tires get so hot during landings they are an explosion hazard to ground crew placing wheel chock once the aircraft is parking.

How freaking hard would it be > to try that, for a big time mile eater like you? How much air should be bled and what's the correct torque for the valve caps ?

Racing tires are designed to have max stick in a certain temp range. One gets that temp by adjusting air pressure: down = hotter, up = colder. This is the same whether one uses Nitrogen or dry air - which is mostly Nitrogen. It is important to keep the pressure/temp relationship linear (don't ask me ask the tire engineers). Air, especially from a compressor, contains water. At racing speeds the tires get hot enough to turn it to steam, causing a nonlinear pressure increase, especially on cages where tires run hotter. Bottled Nitrogen is cheap and readilly available and, most important, dry so racers have been using it since at least the early 60s that I know of. One buys a bottle, sets the regulator to the desired tire pressure, and you're good to go without lugging a compressor or finding a place to plug it in. I'm told that the dryness prevents wheel corrosion but that seems iffy. Other than that ...???
From: Steve Lusardi on 10 Jun 2010 11:35 Of course....the thread is street operation....not the track. On the street, nitrogen filled tires never get warm enough.

What's wrong with this picture? Nothing at all. This is TOTALLY normal for the racist jerk, trying to hide behind actual motorcycle content. He knows NOTHING about motorcycles, but he has no life ands all the time in the world, so this is his way of diddling himself. |
