Hi, I've got SX and Jardine. Pipe's exhaust hole points pretty much straight to rear tire's centre. Already three people have claimed to me that this increases tire wear by heating the tire???? What do you think? I think this cannot be because air draft blows warm gases away... I thought I ask Buell people's opinion. I've got Avon Sport Viper tire and it has worn pretty quickly in last 1000km after installing Jardine. Cannot say has it worn more than used to with original exhaust... I think this is due to softness of the tire.. Any thoughts? | ||

You won't increase tire wear by having your exhaust pointing towards it. The tires get up over 130 degrees farenhiet when you are riding. There is no way that the exhaust puts out enough heat when you are riding to have any effect on the tire temp except in the tiniest fraction. If you leave your bike idling for extended periods you are risking more damage than a hot spot on your tire could cause. I wonder how you exhaust got pointed towards the tire. I run a Jardine and it points pretty well to the left of the tire. You can definitely feel it on your ankles when you are standing on that side.  | ||

yea, I was wondering the same thing. I have a Jardine on an 03XB9R and it angles out toward the side of the bike, more so than directly towards the tire. | ||

same her also. points to the side. i have an xb12 though  | ||

same pipe I have. It has an angle, but the heat goes towards the tire I think. And I think it is installed properly  I talked to a guy that repairs bikes for living. He thought that even few degrees increase in tire temperature can cause more tire wear. Perhaps mythbusters should investigate this  | ||

the coldest tire warmer you can get for racing is 130 degrees http://chickenhawkracing.com/store/item/29tk/Motorcycle_Tire_Warmers/Motorcycle_ Pole_Position_Tire_Warmers.html That is about the same temperature your tires get to riding hard in the canyons. How much heat do you think your exhaust is going to put into your tires when you are in motion? If anything by the time the exhaust leaves the pipe it'll be the same temp or cooler than your tire. Add to that the fact that it is mixed with ambient air you have nothing to worry about. I'm sure your friend means well, but it's not a big thing. Also do not leave your bike idling for more than 2-3 minutes. This isn't because of tires, it's because these bikes will walk them selves off of their stands and fall over. Excessive idling also leads to fouled plugs. How often does your friend run into excessive wear because of exhaust hitting the tires? I can't think of an application where the exhaust is pointed at the tires. If you're really worried you could have a welding shop weld a longer outlet onto your pipe, but that could mess up the tuning. |
