When you lowered both ends, and the astern most, you actually increased rake and trail, which are contributing factor for stability. Lowering the bike, OTOH, will decrease stability. Overall, the two probably more or less evened out.
I agree about leaving the front end slightly dropped and see how you like it.
I am not an expert on the subject. But I had my bike tuned up based on my weight and my type of riding. The sag, rebound and compresion were adjusted front and back. My question is, do you know the sag, rebound and compresion you have as of now. Remember the factory setting is set based in two person (rider and passenger). I personally will recomend you look for a place that does suspension and have it set up for you. Go and take it for a spin and come back for fine tunning. Good luck.
My two cents.
The razor.
Thats 1 of the problems with a zx14 its horribly under sprung. Its set for 150lb rider and I'm 215lb. I need to respring it badly. Thanks for the reply.
