I'm guessing but I'd imagine there are quite a few more turns than 5 to increase the pre load. You'll be able to keep adding until the adjuster hits a hard stop.
Factory front fork preload is set at 5mm, the maximum preload is 20mm, one turn (360°) equates to 1mm. Andy
Set mine up the other day, was only set at one turn from right out, so a lot of sag, went for a quick ride to Chris Walker this afternoon, it's much better now. Set the rear properly as well for my weight.
I applaud your suspension set-up initiatives. Suspension set-up, especially SAG and having the correct springs is often overshadowed by bling. At 80~85kg fully kitted, you're in the zone. Any rider significantly outside this range would require a spring swap. About your fork travel: Short on fork travel may be a compression setting set too high or even a rear rebound setting set too high. More importantly: What's your Rider SAG percentages fore and aft? The fore-aft balance should be close to equal although some, myself included prefer having a bit more SAG up front producing a slight forward pitch. Although this chart and settings thereof are on a manual Ohlins suspension set-up for my Multistrada 1260 Pikes Peak, you may find it useful. FYI: I'm 177 lbs / 80 Kg in full leather gear (160 lbs / 72.5 Kg without). No pillion, All twisty back roads riding. Angel GT tires. As you can see, I'm using 3/4 of the fork travel measured to the bottom-out mark above the fork casting and that's while riding on smooth roads without pushing it. If riding more aggressively or on rougher roads, the zip-tie drops another half inch. In an emergency stop, my zip-tie drops to just above the bottom-out mark.
