Finally got my hands on some vintage Holland made Koni's. Type 7610-1394. According to the Koni records they were built specifically for the RE5. Presently waiting for a rebuild kit to arrive. The document also shows that the stock spring that came with this was 235-18/25/33 and according to IKON this spring is suitable for a rider in the 160-200lb range.
I am about 140lbs so am presently wondering if I should look for a lighter spring? Any skinny guys here able to weigh in on their spring tuning experiences?
Also, I'm not sure if my spring is the correct spring. I measured it and calculated that it has a rate much lower than the stock Suzuki spring. (Stock=124lb/in, mine=88lb/in). Once I get the rebuild kit and mounting bushings I'll be able to install them and get an idea if they are even close...
For anyone wondering about the spring numbering system: AAA-BB/CC/DD. AAA is the uncompressed spring length in mm. BB/CC/DD are the three different spring rates in Newtons per mm. If you look closely at one of their progressive springs you can see that it is wound in three distinct pitches. (they also make some dual pitch springs. I just happen to have a triple rate spring)
