OK, does anyone out there have a good source for some extra heavy-duty springs for a seat post? I put the "heavy duty" springs from V-twin in it, and although it works better than before I replaced them, I still bottom out occasionally. I'm looking for something I can roll over a pothole or large bump and still not bottom out. I realize it won't be 100% but has to be something out there better than this.

Anything would be helpful.

 

Did you follow the procedure in the service manual for spring adjustment? If you are not too concerned about looks but functionality, put a valve spring on the seat post

 

Yes, I followed the procedure to a T. Heard about the exterior spring, but I want the bike to look as close to stock as possible, so that's a "no go" on the exterior spring. Someone said they got a set of "heavy duty" springs from David Croft a while back (2012 I think) that were a lot stiffer and better than those you can get form V-Twin. So if he had them, I'm hoping someone else must also have them.
Another shot in the dark!!

 

Dave Croft sold to Colony and I believed they sell his springs.

 

Colony sells the spring kit you want. I never bottomed out again.
