Can someone tell me what the numbers stamped on the cam gears mead? I've tried the "search" tool with no luck. I have several GS1000/1100 cams...most have the same numbers, some are different. I'm assuming they are a cam lobe profile measurement (lift or duration), but I can't find the conversion to use that results in a meaningful number in mm, inches, or degrees? :? Thanks

I am not sure if its cam lobe durration or the timing on the actual SPROCKET itself. Makes more sense to me for it to be the sprocket part number/timing, because i have cams that are completely different, one set from the 16v 750 and the other from a 8v 750, yet both have the same cam numbers. I do know that most that ive seen are numbered 451 on the exhaust and 450 on the intake, or vice verce (cant remember which).
 
numbers on cams gears?

numbers on cams gears?

Anybody else have some knowledge about these numbers? I have some GS1100E that are 451 Intake / 470 Exhaust. A set of 1982 GS1000S Katana cams are 490 Intake / 470 Exhaust. What do these numbers relate to, specifically. (degrees duration, lift in inches or mm, etc...?) Can't find a coversion that makes sense....thanks
 
They are #s stamped by Suzuki when they are cores so the factory knows what bike they go to. The #s have NOTHING to do with lift or duration. Ray.
 
The gears can't affect the lift or duration, but can change the cam timing. Just a thought, lay your #450 intake gear on top of your #490 intake gear, line the bolt holes up exactly, then look at the teeth & see if they are lined up perfectly. If the teeth are aligned perfectly, the cam timing will be the same with either gear. If the teeth are offset a little, advanced or retarded, the cam timing will be different from one gear to the other. Just my opinion!!!
