Hey, he mentioned R6, not me.

Are XS650 forks that bad?
Lot's one can do to tighten up the innereds, play with oil levels/pre loads and viscosity.

I'd, I'll noodle around with this a little but have several pressing projects holding me up along with a seasonal bug that's kick'n me pretty good.

I bought my XS1100 in 2003 with 10K miles on it for $2K. I have put about 100K miles on it. A timing chain and four gear wheels on the countershaft is all of the powerplant work. I’m sure I’ve spent plenty keeping it up all these years. It starts on demand and I can go anywhere. I’m sure it’s completely worthless. Upside down? I don’t really think so.
The same goes for the new XS650 I bought in 1983.
Wouldn't these (later?) 34mm dampers be the easiest way forward?
put a plastic ring from a 35mm in the groove, modify the end to accept a mikes emulator?

Maybe. Did that groove in the disc (under the cap) have a plastic ring originally?
My damper rod has a 2" sleeve and valve/shim/disc all held stationary in the upper tube with the usual circlip. The rod moves within the sleeve as the lower leg moves. I would think I'd need to retain it as it limits downward travel of the lower leg.

Just musing....
I wonder how challenging it would be to fit a RE Interceptor front end on an XS650. That would mean 41 mm fork tubes. Triumph Street Twin springs are the cheap improvement for the RE fork.

Using RE yokes, quite easy. Press out the stem. Machine a stem like XS650 and press it into the RE bottom yoke. Not too difficult?
I have a set of 41mm Hinckley Bonneville yokes. It's a close thing, they might even fit an XS650 without modifying the Bonneville yoke stem. Without having an XS650 yoke set alongside it's not easy to be certain, but it's very close. Coincidentally, I have a set of new 41mm Showa (Honda, Suzuki etc) on the way. One day I'll get round to seeing how they fit the 650D.

RE 650 bottom yoke and stem. Depending on stem length, it might be just a case of bearings choice. IIRC All Balls have a bearing conversion tool on their website. Might be worth a look.
Good luck with that!

Those 34mm parts were in a tub together, pretty complete set of fork parts no plastic rings so no rings when removed. prolly never there.
Correct, but using the largest possible disc can help, by moving the caliper further away from the hub. The 19" front rim will allow 330 mm or even larger discs. On my 1977 D model with oem spoked wheels, a 320 mm disc with 23 mm offset allowed using a 4x34 mm Brembo caliper (65 mm c-c mounting points), without shaving anything off the back of the caliper. With that setup, there is around 2 mm clearance between floater buttons and the fork slider ( oem 35 mm fork)
I never paid too much attention to my 34 mm dampers when I did the fork seals but looking at a pic I see something in the groove. What is the purpose of that ring? To prevent metal on metal contact between the tube and damper?

Well, I was a bit bored so I looked up the bearing sizes for the RE 650 steering stem. Both upper and lower bearings are 25mm ID. So I think that's the same ID as the XS650 top bearing. But smaller diameter than the XS650 bottom bearing. RE stem could be sleeved to take the XS650 bearing set. Seems the critical thing to know is the length of the RE stem. If it's near, then it's almost a bolt in job if the right bearings are selected. Interesting.

Gee, looks like a piston ring to me
Great intel… Are RE forks easy to source?
To be frank, I have no idea. I have Triumph yokes and generic 41mm Showa forks from Honda/Suzuki, so I haven't really bothered looking at RE stuff. There's a couple of sets of RE 650 yokes on eBay but I haven't looked for forks.
To answer the question. Here's a set of brand new forks offered from an Indian seller. Price is dirt cheap.

I took a quick GTS and looked at the AI response. It said the XS650 stem is 9.5 inches and the RE is 100 mm. Definitely wrong!
If it’s easy to do, the RE fork is stiff. It will take Brembo calipers and an 18 in wheel. The RE fender also has appropriate appearance. I expect emulators are available.
What about total fork length?
