JFab frame rails breaking

What does that mean, it means that the installer failed to make a proper installation. What is it that those of you keep saying where is Jfab want him to say? he bent rails and the consumer installed them, so figure out what your problem is and fix it. It is so easy to right away blame somebody else for our mistakes. I think that it is a matter of time and you will see more break, not because they are weak but improperly installed. I had a set fail (not Jfab's) and upon reflection I re-designed my installation and haven't had one problem (I did a 250 and a 500). Remember the 500 vibrates alot, how many have broken mounts on their steel framed bikes, so the AL will probably break as well unless you have a well balanced motor.
So lets stop asking where Jfab is and fix the underlying problem, and when you do let the rest of us know how you did it so we can re-enforce our designs.
have a good day!

I have made a AF my self with some advice from Jfab and AJ Wagner from service Honda. Frame braking is always on my mind (especially now) but if it does. It's my problem. This these is like the prox, wossner, wiseco piston topics. Give the product you used the fauld, not who installed it. Jerry Jfab has been "away" for a wile like me, maybe even longer because of to much work and others.
I trunned my crank with zero tollorance when I rebuild my engine this summer.
Helped allot with vibrations. And also remember that we do things that wasn't ment to be. Kawasaki R&D for months, we once and than race it!!!!

Like everyone said... the rails arnt to fault.
Jerry even told us he would be away for a while. as his shop had #1 priority. Not like he slithered off into the bushes, he told us!!
I debated removing him from the vendors at that time, but my conclusion was..
why ?
you can call him on the phone, and he answers, and provides his product that way... if I removed him, then no one would know of these products, that make their AF conversions that much easyer..
I know if I was doing one, Id want to know about some guy like Jerry providing parts. even if I had to pick up a phone to get them, not just send a PM.
have any of you actually called him and asked him about them breaking?

i don't blame jfab one bit for the rail failure, i would just like to see his input and what his advice would be. does he already have measurements and proven angles in mind? just a quick, hey this is what i think happened and here is what i would do differently on the design.

FWIW, I know I won't hesitate to buy and use his rails when I start my conversion.

Exactly...I don't care how "busy" he is. He is on this site almost daily. I'm not saying his rails are bad, i'm sure it was a bad install. ....but based on the lack of any response why would any one feel comfortable doing business with him?
