psi

Has anyone carried out a compression test on a 390. I was wondering what a good psi reading is. Did mine yesterday with the decompressor disabled and got 200 psi, but don't know is that's good or bad.

Hi All, On the frame sticker on my bike it says 29 psi front and rear. The max psi is 42. The current psi is 33 from the dealer. What do you recommend I keep the pressure at?
