using E/E shock mount instead of E/C for 80 GS1100ET any problem?

FYI, commercially available stainless bolts are NOT a good material for load bearing members since the higher strength alloys tend to be brittle. SAE grade 5/8 bolts are hardened alloy steel and a much better choice for an application like you have.

"All the weight of the bike is on the bolt alone."

Yes but it's a whole lot less weight than the G models that do the same thing but with a welded stud to the swingarm instead of a bolt. It's the same principle really. I only weigh 140 lbs. so I'm not adding much to it. Things like this make me wish I would have studied Physics and Mechanics instead of Computer Science. :-D

Thanks. That I didn't know. I'll find a grade 8 bolt this weekend.

FYI, Progressive 12 series shocks are available for $131 + shipping from...

You can reuse your old springs.

You shouldn't have any problem selling your old shocks...I'd even buy them if the price is right.

Thanks Nessim but I cannibalized my '80 GS1000G for the parts I needed to get this '80 1100ET running and I'd like to get the G back on the road some day.

Thanks for the quick reply Billy. Makes me feel more relaxed knowing that I didn't screw up, again. I'll check the grade. They might be 8's. I really didn't want to spend another $250 if I didn't have to, just to get a different type of mount.

Id watch using grade 8 on something that could shear...while its the hardest steel, that doesnt necessarily mean it would be proper for this application, as if the way he has this mounted is the way that was described by the others, it creates a perfect shear point across the breadth of the bolts shaft...Ive seen it happen with grade 8 bolts on an auger bit for a PTO drive on a tractor...and in this case, a sheared bolt would be catasrophic if he was riding at any speed at all...

after reading this i should clarify it a bit i think...Grade 8 steel is very hard, making it very strong, and especially usefull in certain instances, but in this situation, being that its so hard, it will have a tendency to SNAP/SHEAR without warning rather than bend, and then break...just my two cents..
