Unfortunately burnishing your bushings does not fix the majority of single crown fork alignment issues. This has gotten super popular lately regardless
It helps a lot. Single crown forks have gotten pretty good in the recent years. Why would a duel crown fork have less of an issue? They both face the same issue in terms of flex between the uppers and lowers. From my understanding the difference between duel and single crown are the uppers being stiffer, not less stiction on the lowers.
Nice video! I'll add my opinion that you need to have the hub installed and torqued to spec to check if it is really tight bushings or if the lowers are out of spec/alignment.
So this may be true on other forks, but for Fox in particular, it uses a floating axle so the lowers being in a neutral position like what was shown is where is should be to not have any binding.
Burnishing makes a fork ‘broken in’ immediately. It’s going to ‘self burnish’ over time anyway, so why wear down your bushings ahead of schedule? This is ok if you replace forks every 6 months or a season (then sell it to the next guy), but if you keep it for years, don’t bother.
Bushings tolerances even with metal backing liners are hard to control in a manufacturing environment, high end boutique forks get a pass of burnishing but SRAM and Fox don't care to do it on retail units since they are expecting a certain level of "self burnishing" to happen, some forks will never be buttery smooth but it's not a necessary process, you're right in saying that eventually most forks would get to that point but there's a ton of outliers with big manufacturing 😂
This isn't entirely true... Doing this isn't gong to wearing down the bushings, you're only setting them back to the shape they should have been from the factory. I also don't think the fork itself can fix the deformation. Sure, it probably does help the bushings overtime but I don't think its something that will fix itself. Also, like mentioned in this video, I did go up a size which the fork would have never done on its own. Another thing that is worth mentioning is that Ohlins had a service for some of there earlier forks where they would burnish the bushing because the first batch had some stiction. So this must mean something?
@@thebigoutsidemtb 'burnishing' is actually involves removing material, ever so slightly - it's shortcutting the wearing in the bushings. Even if they are slightly out of round from the factory, they will eventually 'self-burnish' over time. Run your finger along the burnishing head, they are actually sharp cutting edges. The differnent diameters cut varying degrees of material ever so slightly. And as you experienced empirically, a worn-in (burnished bushing) fork does feel infinitely better than a brand new fork that hasn't worn in. For riders who don't plan on keeping a fork more than a season or two before getting a new one, it's a good strategy. In the end, it's good to have the option. And as someone who lived with an old 1998 Marzocchi Z2 BAM fork (a million years ago) with 'drop in replacement bushings', the loose bushing feeling can get out of hand - I prefer to let em' wear in slow....(old guy talkin')
@@LaurentiusTriarius most folks, including myself, won't mind the glacial pace of 'self-burnishing'.......but, if I had a line on new forks every year, I might splurge a burnishing.

nice video, bud. glad to see you responding to doubting comments explaining everything, keep up!
Appreciate the support man! 🤙 Thanks for watching! 😃

Kind of like new skis are NOT flat. Got to get a stone grind day negative one
