So I have a 1987 GSX-R 750 that I have owned for 9 years now, it was my first Suzuki and it has been phenomenal to me. I have managed to put nearly 20,000 miles on it but I scored some adjustable Cam sprockets and, while its apart already, I would really like to dial in the Cams as accurately as possible (I have all the equipment, piston stop, degree wheel, dial indicator... patience). I can only manage to find physical dimensions to these cams, which specs out as far as wear limits, but absolutely nothing in the way of Lobe Separation Angle, or relative Lobe Centerline Degrees. Long story short, whose got the down-low on stock '87 camshaft tuning so I can get the Advance/Retard, Overlap, etc. spot on? Side note- Ill take as much info as you can hit me with, the more the better! Thanks -Mike-

Never seen stock figures published I suppose most rely on the stamped timing marks - these work well enough. As regard actual degrees with std. cams  & adjustable wheels - 110 degs on both works for me in most cases.
