Thanks Zym! Nice write up of your mods!
Re seat: Did you cup under the sit bones or just dish the whole seat out a bit? Curious on what you trimmed?
Seems like a little sculpting off the back where it rises (electric knife) and shallowed it out a bit (disc sander). I didn't remove more than one inch anywhere. I referred to an old post on this site and used that for a guide but I couldn't tell you now who posted it. All I know is what little material I took off the foam at the right places made a big difference!
Did you buy a used factory seat to do your modding to? I'm sure you can find one for $50 range, it will allow you to take your time and still be able to ride. Then you can sell yours to recoup the cost.
JPT. That is a good idea. Thought about buying one but honestly didn't think about selling mine later. I might have to do that!
If you are going to do the build, essentially you just need the pan, so you can buy one that is in not so good shape to save money. You will have to recover the seat anyways, so you can buy one with cuts...
Then when you sell yours, as long as you sell if for more than the beat up seat, you come out ahead.
