    GS1100 - 4-Valve per Cylinder or not?

    I have read conflicting things.

    Is my 1982 GS1100 GLZ a 4-valve engine or not??

    Your G is a 2 valve motor, the E's are 8 valves. I don't believe they made the G with a 4 valve head.

      The easiest way to tell with any GS engine is to look at the cam caps - If they are round - it's 2 valves per cylinder, if they are rectangular in shape - it's a 4 valver ... 8)

      And Jethro is correct - they didn't make any G (shaft driven) model 4 valve engines. Suzuki did, however, make a few L model bikes - both 1000cc and 1100cc with 4 valve engines that were all chain driven.

        OK, because I think I am getting ready to run into the same problem that Deathwish had with his jet kit. I just bought one from K&N and it has the huge jets (165 and 170's) included with it....

            JETHRO,,, You've got me confused, 2 valve? 8 valve? 4 valve???? I'll bet you were trying to say the shaft drive 1100 engines have 8 valves, 2 per cyl. The chain drive 1100 engines have 16 valves, 4 per cyl
