I am about to replace the front fork seals and oil, was wondering if I should consider changing the stock springs, has anyone done this and what benefits did they feel ?
If you weight 130 pounds, your probably ok. However, we all don't weight the same as Honda's test engineers.
I have a ST1300, and when one seal began leaking at 120k, it was time. I replace the seals, dust seals, don't forget the bushings and fork springs. (recommend only OEM seals, dust seal set) 10 weight Honda fork oil. I went from the stock 0.86 kg/mm springs to 1.00 kg/mm for my weight. It took 3-to-4 attempts to get my preload spacers cut at a length to support my sag. Started out at the stock oil level and had to add 10cc a couple times during preload spacer changes.
I knew the rear shock was dead and riding on the OEM soft spring, so I changed to a (REBUILDABLE) Penske rear shock and it improved the ride greatly. If your going to invest in a rear shock, don't go with the $500 non-rebuildable shocks).
Good luck and have fun riding.
