Seems like everything I do to this bike is challenging. I am rebuilding the forks, and I needed to replace the upper tubes, since they were badly pitted. After about a month of scouring the country for a junkyard pair, I came up empty handed. Aparantly, this fork is unique to the 1979 GS750LN model. Suzuki was no help, since the parts were obsolete. :evil: Luckily, "Forking by Frank" was able to fabricate a great set of replacement tubes for me. 8)
Now I need fork seals, and I believe the application charts are incorrect. The Leak Proof seals I bought for my bike are 37mm ID x 50mm OD x 11mm thick. These were a very tight fit, and the metal backup washer didn't fit down inside my lower fork tubes because it was too large in diameter.
I measured the old seal, and it appears to be about 37mm ID x 48.38mm OD x 11mm thick. This is similar to the seals used on some old Goldwings and Yamaha Specials from the early 80's. Those bikes use a 37 x 48 x 10.5 seal.
I talked to the guy at Leak Proof, and he is going to send me (free of charge) a set of 37 x 48 x 10.5, as well as a set of 37 x 49 x 8. The latter seals were used on 80's vintage Suzukis.
So, does anyone know what size seal the 1979 GS750LN really uses? :?

I believe that the application charts are incorrect for my bike. I've cross referenced several seal manufacturers, and they all call out the same size seal, but it is different the the OEM seal that I pried out of the lower fork tube.
