Hello F6B Forum,
To answer all your questions on the SuperBrace install, Lets start with the "Loosening of the axle bolt/pinch bolts question." Many riders want to know why do you have to loosen the axle pinch bolts/axle bolt when you put on your SuperBrace. Well the simple answer is sometimes when a front tire is changed, the mechanic over tightens the axle bolt because they are in a hurry. What happens then is the dimension from center to center on the fork legs change.
Now this creates a couple of problems. With the over tightening of the axle and the fork legs not straight, problem one is your fork seals are wearing out faster because the fork legs are pinched in. This gets us to problem two. Now the SuperBrace doesn't fit because the center to center dimension is not correct. By loosening the axle pinch bolt/axle will allow the fork legs to relax and go back to the correct center to center dimension. Now you can install your SuperBrace correctly. Follow the install instructions and Re-torque your axle bolt back to the factory specification. Now this leads me to a couple of other questions that riders ask all the time. "Why does the Kuryakyn brace bolt right on without loosening the axle bolt." Well there is a simple answer to that. The Kuryakyn brace is adjustable with slots in the top to adjust it to whatever dimension is on the bike. Hhhmmmm. The interesting thing about that is if the mechanic changing your tire over tightens the axle bolt and you wanted to put a fork brace on your bike, the Kuryakyn brace would easily install with your over tightened axle. You would NEVER know. Then later the fork seal blows out. This is the way I see it. There is only one center to center dimension on the fork legs. And yes there is a very very small manufactures tolerance on this dimension for you machinist guys. The SuperBrace is NOT adjustable and has the correct center to center dimension just like the motorcycles triple clamps that are holding the fork legs. Obviously the triple clamps are NOT abjustable, so why would your brace be? Did you ever hear of an adjustable triple clamp? Of course not. There is only one center to center dimension from top to bottom and you want that to be perfectly parallel and on the right centers. An adjusting fork brace just adjusts to your problem. If the SuperBrace doesn't fit on the sliders correctly, you now know you have an over tightened axle and you will need to loosen it. I hope this has given riders a better perspective on how the SuperBrace works.
Ride safe,
SuperBrace
