Thanks,
    In my opinion it's pretty pointless to ask how just bolting on has worked for someone else. The catch is that there seems to be huge tolerances in stock factory timing. I mean up to 10 degrees or so. So even if just bolting on has worked perfectly for someone there is no guarantee that your result would be anything similar.

    10 degrees? Really? You would be OVER 1 tooth off on a 30 tooth Suzuki GS1100 sprocket

    Don't laugh....On early GSX1100's when changing the lobe center positions of standard cams, I've frequently had to install them with one pin less separation between the 2 and 3 marks.
    When the OE inlet lobe center measures up at 118 degrees - and you want 108 degrees - slotting will only get you so far.

    There is of course a written note of this given to the owners for future reference.

    Later 1100's and the 1150's seem to have been a lot closer to where they should be.

    I must have been lucky, Been so long I don't remember the #'s but neither of mine were nowhere near a tooth , or pin, off. I do remember I decided on 107 IN. & 109 EX., & that gave a ton of torque. I can't even remember what the OEM specs would have worked out to in terms of lobe center. Dang, all that was 40 birthdays ago.

    I was doing probably two a month in the shop I had in the mid 80's. Dial the cams, a pipe I had made up to my specs locally and rejet the carbs.

    The worst I remember was an inlet at 122 deg LC.

    Do you remember what the Suzuki cam timing specs worked out to in terms of Lobe center. I remember having one of mine up to 115 or 117, but that raised the max HP rpm. way higher than I was comfortable with & lowered the torque quite a bit.
