    GS1150 camshaft specs.

    Does anyone know the camshaft specs for the GS1150 ? I have seen .315 lift and .330 lift and have heard nothing on duration . Any help is appreciated .

    I was going to ask you if you had checked in the manual, and point you to the link on BassCliff's site, but it seems he does not have a copy there.

    So, ... I copied the picture from my copy of the manual and am posting it here for you.

          Without finding the actual specs, I’m pretty sure that they have more lift but not much more duration if any than 1100 cams. We use 1150 cams in turbocharged drag bikes which like lift but not a lot of duration.

              Terry,

              (lift) 8/7.5 mm and (diameter) 28/23 mm (Intake/Exhaust)

              from the manual.
