I will do the best I can for you Jimmy.
I got eight new springs with the silent cross over rings. The stock springs do not have the cross over rings. There is a big difference in the springs as far as wire diameter and spring lengths.
The biggest is in the rear. The lower spring is a little shorter and much less in wire diameter. the top or tender spring I think they call it is now a lot longer and is not in a coil bound state like the stock one was.
The front lower springs seems to be about the same length but now slightly smaller wire diameter. the top tender spring is now longer and a larger wire diameter. I did not ask the spring poundage ratings.
I did not check the ride height before I took it in, but it seemed a littler higher, or at least for my wife trying to get in.
They asked a multitude of question on my riding style and desires along with tire size added accessories my weight, wife's weight, gear weights and changes that have been made to the machine and any future mods to be made.
As for the internal valving, he named off several changes that had been made, but where all Greek to me.So i can't explain them.
They added schrader valves, filled the shocks with new full synthetic racing oil and nitrogen.
They spent a lot of time in setting the finished ride height and testing to make sure all was correct.
The total cost was $1438.75 and worth every penny...
After my test ride last night, I could not believe the amount of change this has made in my machine. And I am really looking forward to more riding today and in the future.
In a earlier post you asked for pictures on my dust control subject. I have pictures on my cell phone and can take pics of the new springs ect.. But I do not know how to post them on the site, is why I have not done so, so far.
Call it being a senior and not real brilliant into this new computer age.
Hope this answers some of your questions and will be glade to help more if I can...DRK
