HOW TO CLEAN YOUR KTM FILTER: MR. KNOW-IT-ALL

Dear Mr. Know-It-All,

I’ve seen numerous totally different opinions on cleansing KTM/Beta-type air filters. Do you take away the rubber grommets from the filter once you clear and oil? Most say no. Seems to me that’s an unoiled a part of the filter for those who don’t take them out.

This missive makes my tooth damage. Why? Because I’ve in all probability cleaned 1000 Twin Air filters over time and have by no means thought twice about yanking out the grommets previous to a cleanse and lube job. But then once more, I experience the sharp facet of the “excessive orderliness,” so this process appeared pedestrian to yours actually. That being stated, I questioned a double fistful of my using colleagues, a lot of whom have KTMs shoehorned of their Sprinter vans. And, I got here up with precisely one one that yanked the grommets—me.

I take away them previous to washing and reinstall them following oiling. Why? I don’t need to invite any grime to slide into my machine’s powerplant by way of an air filter that hasn’t been totally maintained. Don’t be slothful; take two seconds to take away them.

RACE SAG FOR YOUR FORK: MR KNOW-IT-ALL

Dear Mr. Know-It-All,

I’ve heard how important sag is and found a lot of information on rear sag, but, surprisingly, little on fork sag. Could you please trickle down some of your vast knowledge on this subject? As an example, I have a 2021 KTM 300XC-W and ride mostly beatup single- and double-track in the forest. I am 185–190 pounds full gear. Thanks in advance.

Great query, Steve. Improper fork sag and spring preload can unhinge the handling traits of your machine. I spoke with Dick Wilk, a suspension expert, to get his insights on setting front sag:

“Similar to the rear, the static sag is the most crucial and should be around 25–35mm. Unlike the rear, the front sag is generally not adjustable externally, which is why there is limited information available. However, you can set the static sag on the shock first and then fine-tune the front by raising or lowering the forks in the clamps to find a comfortable handling setup. It’s important to note that the fork spring preload should be between 3–7mm. This is significant because over-preloading can negatively affect the front’s ability to absorb small impacts, maintain a line, and handle tight, rutted corners.”
