    Installed the shocks last night. Well, almost. Top shock nut stripped the thread when I took it off. I plan on running a smaller die down it and putting a new nut on. However, the right side lower shock mount seems to be shorter than the other 3. Is this normal? Any suggestions on how to make it equal length? And are acorn nuts necessary here, or can I just use a regular nut?

      Still looking for a solution to this. Is this stud removable and I can just replace it? Should I try making some kind of sleeve to screw onto the stud that's there to extend it? Maybe drill out the center and put a smaller stud in the larger stud?

      I was holding off on pulling the carbs, but I think I'm going to. I know the bike runs, so might as well go all in. I was holding back so I didn't ruin the rubber boots, but if they rip I'll just replace them I guess

          I've looked into that. I plan on running a die down the top mount, but the bottom mount: 1) there's no material left to run the die down, and 2) It's on the swing arm, so I'm not sure if the same options would apply. Using the old one as a sleeve is what I'm thinking of doing, providing I have the means to permanently attach the new bolt.

            Had a lot of things happen here lately, so the bike hit the back burner hard. BUT! It's at my new place now, and I have more time and money than before to throw at it :-P. I've replaced the kick stand the PO shortened with a OEM one; I also installed a center stand. I've got a spare seat to cut up, and ideas are swirling in my head. Right now the carbs are off it for dipping. Hoping this clears up my cylinder 3 issue and she purrs nicely once back together.

            Here's my plans: With the bars I have on it, I feel pretty comfortable (although I haven't been on it long), so I'm going to work with them. I'm planning on swapping the mirrors for some bar-ends. I want to move the tail forward and shorten/eliminate the rear fender. This will also require a smaller seat (hence the spare to cut up!). While sitting on it, my feet naturally pull up to the passenger pegs, so I'm debating on making linkages to use them for rearsets. Just not sure if going that far with it will work, but we'll see. It currently has factory gauges, but that may change; they stick at the moment, so if I can free them up, they may stay.

              Rebuild kits for all master cylinders and calipers are on their way, along with stainless brake lines . I also ordered new carb boots and bowl gaskets. I already have the o-rings and am slowly working on cleaning the carbs.

                Carbs are done and the bike is running. Cylinder 3 now fires! But, it's still on the lean side; some slight popping at idle and hesitation on take off (only in gear; RPMs jump fine in neutral). Looks like it's time to check the timing and valve clearances.

                I pulled my tach cable out, to see if it was the reason my tach wasn't reading right; cable looked good and spun freely. So, the fact that both the tach and the speedo are affected, I'm thinking my gauges are sticking. I'm gonna try spraying some WD-40 into the drives and hope that frees them up; otherwise, I'll be looking into another set of gauges for it.

                  You're on the right track on the instruments, but use Deep Creep or Tri Flow instead of WD 40

                  Take the gauges off and tip them so the connections are pointing up. Squirt a bit of lube in, then wait 5 minutes or so and give it another squirt. Leave it that way for a couple of hours and reinstall

                  If that doesn't work, you may have to open them up, clean and lube the gears with a very light grease

                    Got all the lights wired up today. Still waiting for brake parts.

                    I sprayed some Boeshield T9 into the instruments. It's a penetrating lubricant. So far, no change. Hoping I don't have to take them apart, but it's starting to look that way.

                    Put my bar-end mirrors on. Nice to actually be able to see behind me! Hoping they hold out, as I like the look of them too.

                    She's getting closer to being ready

                        Took her for her first real outing Saturday. Rode up to Daytona for bike week! She did great going up there; rode nicely, plenty of power, good brakes. Coming back though, one of my coils dropped out. Managed to limp her home; a 130 mile ride on just 2 cylinders! Will start troubleshooting the coil later this week, but I"m thinking of just biting the bullet and going with a Dyna system.

                          Wish I someone knew this. You drove right by me. You could have stopped by my house and picked up a used coil. If you still need one let me know.

                            There's plenty of used GS coils on ebay, almost all will work.

                              That bike has points, if it is stock. They could be worn, or it could have a bad condenser. Take a look before you decide on the coil. The wires are long enough for you to switch the 1&4 plug wires with the 2&3, and you can switch the wires from the points on the low tension side of the coil. If the same two cylinders are dead, it isn't the coil, it is upstream of the coils. If the other two cylinders are dead, it is the coils or plug wires.
