    Question Cam Degreeing or not

    How important is it to degree a set of drop in Web Cams in a GS1150 .340 lift or even a set of .348 lift. Would it increase H.P. or just move the power band around..Thanks..I know Web recommends degreeing all there cams.Is it a power thing or a safety measure? Thanks..

    You need to degree them timed at the figures they quote for the power characteristics they claim.
    Just bolting them in on stock sprockets may leave them advanced or retarded a degree or so.
    The profile is usually ground pretty close to the stock cam sprocket mount but tooling wear etc can't guarantee that it's spot on so degreeing is the only way to get it correct.
    The LC method is easy and straight forward and worth learning if you want to play with the effect of closing the centers etc without lining somebody else's pocket.

    I'm sure there is some of both in that recommendation.

    First, stock cam timing can be all over the place. There is plenty of tolerance stack up and wear available to significantly alter it from the design numbers. You should realize that the cams turn 1/2 the speed of the crankshaft. Cam timing is measured at the crank, so a 1 degree change at the crank is 0.5 degrees at the cam. That is a very small amount of play but is big enough to noticeably affect how the engine runs.

    Second, it makes no sense to me to spend the money for aftermarket cams and then not bother to degree them. You spent real $$$ to get a high performance part for your bike and now you want to cheap out on the installation and possibly compromise the performance of the expensive part you just bought?

    If you have never degreed cams you will be amazed by how much you can alter the character of the motor with only a small change. IMO, it is absolutely worth the time required to do it.

    Can you expand on what the LC method is? Or, if you have a link you can drop that would be super helpful.

    GS11ezrydr, are your Web Cam cams new or used?

    New..never been installed.. And thanks to all for the insight, I have a degree wheel,dial indicator,base and stand,piston stops,etc.I,m satisfied it's worth the time and money..I was just curious about others opinions..And if anyone ever experienced what happened just bolting them to stock sprockets,I'll slot the stockers a little or order a set of aftermarket sprockets...should make tuning a lot easier.. Thanks,

    Oh nice dude. Sounds like you've got everything you need

    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.
