Thanks for the info Jürgen. 18psi is enought for my engine setup. For sure !!!
@ ACE 23
As you can see on the race pics, Ive used an underbraced swingarm 3 - 9" from Canadian Mike.
Set on 5-6" over, dependent on the rear wheel sprocket.
The shorter swingarm (you can see it at the newer pics) is 0-6" over. Set on max. 4" for the street.
Furthermore is the Busa a little bit higher for the nice curves in my home area.
The tail is from catalyst and 4" longer.
Hope,I was able to help.
Mike
