86 350X bearing carrier

[GeoD]

Hello folks! I am reviving my 86 350X from 14yrs of storage. All is going well and it's almost ready to ride for another 40 years! One thing I noticed is the rear is binding up and I can't easily push the trike around. I'm interested in a double row bearing carrier and wanted to know if anyone had any suggestions of a brand I should look to purchase. The rear has a DuraBlue HD extended axle.

I bought one of the last 85 350X aluminum double row carriers back in 2007. I say this because I have not seen an 85 carrier available on eBay or Amazon lately. I believe it was a Lone Star carrier.

I asked Gemini AI the question and the following are the results:

For a 1986 Honda 350X running an extended DuraBlue HD axle, a billet aluminum carrier is the best choice over a factory cast unit because it won't flex or crack under the added leverage. Now that the engine is tuned and pulling cleanly without that mid-throttle bog, a heavy-duty twin-row setup will ensure the rear end can securely handle the torque.

The Niche Rear Axle Bearing Carrier For Honda Atc350x 1986 is an excellent plug-and-play upgrade for your trike. It is machined from 6061 high-grade aluminum and comes pre-packed with double-wide heavy-duty bearings that easily outlast factory single-row bearings. It also includes a highly convenient center-mounted Zerk fitting so you can quickly pack it with grease without tearing down the rear end.

If you like, I can pull together some heavy-duty swingarm bearing kits or chain and sprocket combinations to completely finish out your rear-end rebuild. Do you want me to do that?

Which sprocket assembly are you using on the DuraBlue axle, '85 using standard nut & bolt or the '86 with a countersunk bolt & nut?

I will have to get back to you when I can take a look at things. I'm gonna assume it will be the 86 countersunk bolt and nut.

I took a quick look at both my 85 and the 86 350X sprockets and they are both definitely different. I'm going to say the 86 has the counter sunk sprocket as you mentioned. I will post some pics later today when I get to the garage.

The '85 is correct. Now the '86 I need a picture of the opposite side (bearing side) but what I think I'm seeing is the DuraBlue axle used a pressed on hub flange and you bolt a sprocket to it, not countersunk bolts, that's why you need the "85 carrier. Expected to see something like another 3ww member "Shawn"s axle setup where he needed a spacer to line up to the countershaft sprocket.
