Hello All!
My GS1100E had the typical noisy clutch when I got her. I pulled the basket to find a loose nut, and a looser set of springs in the hub, along with grooves. I eb*y ed another whole clutch assembly, used, and used the two to make one.
I mic'ed the fibers and steels and they all seemed fine. I took the hub I bought and ground the rivet heads off the back flush and pressed them out. I took my trashed original and ground around the edge of the heads and pushed them out. I also took the top hat shaped spring seats from the trashed hub. I then took my replacement hub and put the extra spring seats in opposite the originals to tighten up the springs (the trashed hub was so loose you could shake it like a maraca). I then pressed the longer rivets that I ground the edge off into the hub and then, with the whole assembly pressed together, TIG welded the rivets to the back plate. Everything tight now.
I assembled everything back in the bike using the best parts of the two sets. I did not get to ride it much before I did this, but it was much, much quieter now.
So, now I am riding it much more aggressively, since the original set up had so much noise and vibration I thought for sure I was going to be pitching parts through the cases. Now I have a persistent slip under hard acceleration, possibly the whole time, but most noticeably as I watch the tach (my speedo isn't working at the moment) and the RPM flashes from 4.5K to 5.5K for a second and then back down to continue climbing up until I shift. It is almost like clockwork. I did not get to ride it this hard before, maybe it did it then as well.
My first thought is to change the clutch springs to Barnetts, perhaps the whole clutch pack. And that is in the cards, I am just curious as to why the slip in the mid RPM range and not the lower or upper RPM?
Right now a hard launch (as hard as this bike seems capable of now) produces no theatrics, no wheelspin, no lift. Pulls hard from 2k up. I don't know if this is clutch slip, a tired, or poorly tuned motor, or because I am a fat bastard, not a 180# 20-year-old anymore, like when I did this sort of tomfoolery back in the eighties. I just know GS's are supposed to be the building blocks of some of the best dragbikes in history but you wouldn't know it from mine.
What do you all think is my issue(s)?
Cheers, Erick
