I suspect most people are reusing the inner collars (52141-286-000) but are you guys replacing your original rubber cups (52144-356-005 and 52145-329-000) that go between the frame and the swingarm?

What about the bushings (50157-286-300) in the frame backbone?
To answer my own question, I was not able to source new replacement inner rubber seals (52145-329-000) to go between the swingarm and frame backbone so I ended up cleaning and reusing my old ones. It's not perfect but it's better than nothing. I did find the outer metal reinforced rubber cups (52144-356-005) but they cost like $14 each. I ended up sourcing new inner collars from Sunter Honda. The new ones measured identical to my old ones. I probably could have gotten away with reusing them. But the old ones had a lot of surface marks and corrosion so when I put everything back together I used the new ones since I had them.

Emailed Bob Thursday night, PayPal'ed him Friday. Got my bushings for my CB360 today (Monday)! They look great, Bob also said that he made a run and has some in stock so if you're looking for CB360 bushings now is the time!

I just sent Bob an email. Hopefully he has a set for the CB350's that isn't listed on the CBX site or is planning on another run.

He wrote me back and while he doesn't have any available right now he is taking pre-orders and will be making about 25 sets which should be ready in the next 3-4 weeks. Just waiting on the invoice so I can pre-order my set.

If you knew the dimensions you might find that these bushes are available as a standard part from a bearings vendor.

For example, I bought these bushes for my CL175, after I foolishly melted the original hard rubber bushes at the powder coaters.

AL2026-20 Oil Filled Bronze Flanged Bush 20x26x20mm - on Ebay, around 20UKP for a set of four.

The steel sleeves were a sliding fit before I pressed the bushes into the swing arm, but needed a quick ream with a 20mm blacksmiths bit once fitted, to keep the nice sliding fit. I also needed to file down the outer flanges a little, otherwise the swing arm pivot was binding when the bolt was tightened.

ok, Im redoing my swingarm bushings, is there anything that replaces the need for a pivot bushing? I recently bought a bronze thrust bushing on ebay and I believe it only replaces the stock plastic thrust bushing, i still would need to use a new pivot bushing.
Any suggestions?
