My talk are general consideration and will assume that bikes are fully sound.
If so, it can be perhaps possible solve a stability issue, by forum, otherwise not.
As you write here it's supposed you are also able to read too.
One thing that you can read, without be mislead, is your owner manual.
It will give you a good idea on how your bike will react when you change your suspension
spring setting.
That's means you change the height of front and rear end on the static standing bike.
Thus its geometry, rake, trail, wheelbase, height of CoG and even more.
Hydraulic is involved, but in another way, is just related with the speed the geometry will vary through its range in dynamic situation, giving also dramatic differences.
Manual is not discussing about pushing up or down fork or changing the length of shock absorber, but if you look for more extreme change in your bike driving moods, and you know what you are doing, it can be done.
Much wiser 1 mm at a time than a stupid 1/2".
Everybody had try working on suspension and have enough driving sensibility can tell you, that if maybe not with 0.5 mm, with slightly more you will fell your bike changing.
Even if it can easily seem impossible, to me also, experience will tell you that.
Returning to readings there are plenty author that will you give an help on motorcycle dynamics (i.e. Tony Foale)
Instead, to don't be fooled, you must give a different use to special paper where you will print following quote from a fully bloated guy*.
Yup. Exactly. Because it's increasing the rake* and Buells are already pretty maxed out!
At the time XB born was probably the road bike with the lowest (21°) rake (caster) on the market.
So just the reverse of the true.
Trail 83 mm and wheelbase 1320 mm were also really extreme, directed towards supreme handling.
Nobody believed should be possible drive a bike with such a geometry over 130 mph and keep it on the road, but she does, and very well when she is ok.
Stay alert, weight very well what you are reading, somebody is really poisoining you and your buell with his belly gas blowed with his word.
Also usually on a standard set bike if you lift the front, or lower the rear, setting the springs or moving fork itself, you lose handling but gain high speed stability by increasing rake/trail.
So says books and experience, and also looking at a trial bike rake/trail or a dragster ones can give a smell of it.
It seems cossack84 solved a stability problem lowering the front, but I suspect that, done the slight 1.5 mm movement and the dramatic improvement, something else could be involved that has been perhaps solved by itself loosening and retighten clamps bolts. Maybe.
Anyway my full compliment to who thinking with their brain and talk with their mouth, and my full dislike to who are using instead respectively their intestine and their ass.
edit:* time to say that's Cooter.
sheesh. Crank up the heater! Its 72* now and I'm more comfortable at 72.0001* hahahaha.:angel:
