    Opening crank case

    I have 83 gs750es and I Need help opening the crank case to install new timing chain. I've removed the screws in the front of the engine the scre and nut at the back of the front sprocket, underneath the starter motor, 4 screws at the top of the motor and three screws at the back side but top part of the case still won't open. the service manual I have doesn't really say how to but more of just removing parts untill the case is open and I don't want to remove anything unnecessary, am I missing somewher?

    Don’t know which manual you have but there’s a Suzuki Factory Service Manual on BikeCliff’s Website that you can download.

        There are 2-6mm allen head screws inside/top, where oil filter resides, have to take oil filter cover off/oil filter out + one long bolt in front of oil/sump screen + plates behind clutch basket & one plate probably covered in chain lube forward of the front sprocket. Cardboard to poke various bolts in their proper home to keep track is always helpful on reassembly.

          Have you flipped the engine upside down, removed the oil pan and the rest of the case bolts? And pulled the clutch hub and the Phillips head screws behind it that hold the metal plates that also tie the case halves together?

                If your only goal is to install a new timing chain, it is not necessary to open the crank case.
                There are open ended timing chains for sale.
                You remove the valve cover ; break the current chain and attach the new one.
                Pull the new one through and connect the ends.

                  There's a strong feeling against doing this, Personally I change the chain out in any case if the engine is open. However I think the soft link option is a very good one, I have done several this way and never had a problem.
                  If manufacturers like DID offer soft link options then that says enough for me.

                  Don't say can't, as anything is possible with time and effort, but, if you don't have time things get tougher and require more effort.
