Rear sputhe engine stabilizer / swing arm pivot bolt?
Has anyone removed their swingarm pivot shaft with having the rear sputhe engine stabilizer on? I can not get my pivot shaft out. Its a v-twin shaft with a welded head on the one end. Only put the shaft in a few years ago. I know it could be seized In there but before removing the entire primary to pound that ****er out I wonder if taking the sputhe stabilizer out would help relieve the pivot shaft?

Yeah, coat that baby with never-seize. It's hollow, right? Take the bolt out of one side and stick a rod in there and bang on the rod. Hopefully it will come out. I spent a week or so on and off getting one out of a Triumph. I don't recall what finally broke it loose; I suspect it was just a RBFH, or maybe a jack hammer....

Yes, taking the Spudhe stabilizer off can definitely help. It sometimes puts a slight bind on the frame or the bolt itself. Remove it and try again. If it's still stuck, you'll likely have to go the pounding route, but it's worth trying the stabilizer first. Good luck.

How does the Sputhe put a bind on the swingarm pivot? The attaches to the frame side and motor side of the rear motor mount. At least the old ones do..
If anything remove the bolt on the primary side and try to twist the shaft free with a socket on the right side.. The only other place it can bind depends on the model year, either tinkens or spherical bearings. Might get away with loosening the bolt and prying between the bolt and inner primary..

If it's stuck, loosening the primary side bolt and trying to twist the shaft with a socket on the right is the right move. If that fails, pry between the bolt head and inner primary once the bolt is loose. The binding is in the sleeves or spherical bearings.

The Sputhe binds because its rigid link replaces the factory rubber bushings at the frame and motor mounts. It locks the pivot shaft to the frame on one side and the motor on the other, preventing it from rotating freely in its sleeves.

While the second prat is a repeat of what I wrote, the first part don't make any sense unless they changed it from the ones that I know.. The sputhe basically uses the rear motor mount bolts, both on the frame and tranny for the mounts with a ball end link. It don't get close to the swingarm.. You got a pic?

Yeah, I'm confused. The swing arm is hinged to the trans housing, not the frame. The Spluthe shouldn't put any stress on it, unless that stress is really coming from the shocks, which do link the swing arm to the frame. Still, taking the Spluthe off won't change that, either, just make it a little more flexible.
