Carrera
As Roll put it,, much better than me,,, changing the Geometry is not only personal but also,, my words----- dumb to do, unless you know exactly what you're gonna get..
I have No familiarity with AME so I will not comment,, I'll just say this..
No matter how well a Co. performs it's work and how perfect the results,, if the work/change should not ever have been done in the first place, it's simply a bad thing..
I believe you're one a those guys that need to experience this on your own since you are adamant about getting a raked front-end..
Some guys,, and I was always one of em,, need to get the First-hand experience with stuff before believing..
Hands-on experience--- nothing like it..
I'll guess/bet that when you're finished and feel it,, you'll swap that stock front-end back on..
There's a reason you see waaay less raked sickles now-days..
The correct manner to get a rake is via the frame neck modification..
3 - 5* isn't that bad.. I've built 40* sickles with correct trail but it still felt like I was running on a greasy road in turns..
At present, my 120" is in a 35* "neck" with alota trail, bout 7",, sooo freakin steady I have many times screwed down the throttle and hands-free at over 100..
But my other 2 frames are old-style stock 30*,, I like them best..
Here,, go here and read a wee more and don't get hung up the first photo,,,,,,, holy jeeeeeze..........................
