What do you think about these valve springs and does anyone know how much lift they are good for?

I am using the 913's I believe. They are 160 lbs on the seat with a seat height of 1.9 ish.  Coil bind is around 1.3. I can't remember what the valve lift pressure is. Wait for another reply but I think you have the last set number I used. They were around 120ish on the seat. I used them with the Comp Cams high lift series .545 cam. I had valve float big time above 6000 rpms. They would be fine with a smaller cam of course. What cam do you plan on using?
If it ain't wide open; it ain't running.        Rule number one in motocross racing: Pin it; row the gear box; and wait until you hit something.     At work my motto is: If you need me, call someone else.

The #911 is designed for a hydraulic or mild solid cam. If you're under .550 lift you should be fine. Check with the cam manufacturer for recommended seat and open pressures before buying any valvesprings.  :yesnod:
