    86 350X bearing carrier

    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.

This unit is heavily reinforced and machined from 6061-T6 aircraft-grade aluminum to exact OEM replacement specs. It arrives fully assembled with the double-wide bearings, central spacer, two new seals, and a grease fitting, making your installation quick and simple.

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.
