'99 FXSTC in the garage! Advice, recommendations and opinions welcome!
I don't have O2 sensors installed - the bung is plugged. But due to the bung on the pipe it gets heat closer to the reservoir than the stock pipe.
Yes. I have actually been looking at replacement forward controls with a master cylinder that would eliminate this situation all together.
It never ends, but in a good way!

The bung on my Hooker step tuned exhaust have recessed plugs like I’m talking about.

The Best of Harley-Davidson for Lifelong Riders
There is obviously a benefit I expect from the fork inserts, but I have also experienced a front-end "clunk" from time to time when hitting a significant bump at speed. Unsure the root cause so I am going all in.
Gonna break-in some new tools and swap the carb-cables for shorter ones to clean-up the front view as well.
Here we go!
It's a good idea to drain the forks BEFORE laying them on the work bench. Ask me how I know...

Found the steering head bearings pretty dry. Some of the grease was closer to a loose putty consistency than actual grease. That said, they were in better shape than I expected. The races are pretty clean - no rust or gouging.
They're smooth to my finger, so I've decided not to replace them - new bearings yes, new races no.
I've also decided to stick with the stock triple-tree and send back the Acutronix tree.
Few reasons here... First, I'm a bit uncomfortable with the upper bearing "install" as it appears to be press-fit with with the install of the upper clamp. Unsure about the effort to remove the tree with that bearing pressed in that way in the future should I decide to change things up (as we are want to do!).
I guess the tree would need to be punched-out, but this was the least of my concerns... Bigger issue was that the tree lower clamps on the Acutronix tree are narrower than stock which would cause the marks in the stock tubes to show. I don't have firm plans to change out the forks just yet.
And finally, I'm pretty sure I ordered the Acutronix tree after drinking a bit and "sober me" knows the $$$ can be better spent elsewhere.
All that said, the stock tree will clean-up nicely and do the job just fine. This is a daily rider, not a show-piece (but it is damn sexy, right!? I know!!!) And I was also a bit on the fence about giving-up the fork-lock / pad-lock functionality.
The Motion Pro bearing tool made easy work of both pulling the old lower bearing and installing the new one.
I've go a few parts I am waiting on, so this will take a week or two to completely button-up. I'll be rebuilding the shocks shortly - and I'll be spending some time on those spokes while waiting on parts.
