Was out on the MT yesterday and I kept finding that on round abouts the front just felt really vague and like it was about to wash out. So I decided to finally setup my suspension today.
Took the bike out for 20-30 mins to warm up the suspension, then set it up as follows.
Front Forks
Rider Sag: 28mm (I was aiming for nearer 35mm, but I only got 28mm with all preload removed...I need softer springs being only 5’4” / 162cm and 70-ish kg)
Static Sag: 18mm (should be 10-15mm, confirms that the stock springs are too stiff for my weight)
Compression: 6 clicks out
Rebound: 3 clicks out
Tyre Pressure: 36 psi
Rear Shock
Rider Sag: 30mm
Static Sag: 8mm (should be 8-10mm), so the stock shock spring is just about ok for my weight)
High Speed Compression: 2.5 turns out
Low Speed Compression: 7 clicks out
Rebound: 4 clicks out
Tyre Pressure: 34 psi
The settings above totally transformed the bike. You can feel more weight on the front and it would be even more if the springs were right for my weight. However I now have loads of feel from the front, it doesn’t want to tuck on round abouts and it is just way more planted.
Hope this helps someone.

These settings are pretty much identical to the ones added to BJs long termer by James down at JHS.

You are lucky that you are light weight ; as the rear shock is not great. I upgraded my rear shock and that really sorted out the bike for me . Here are my setting that were for 100 kg me and my riding: Front Sag 31 mm Pre Load 9.25 Turns C/W In (Standard) Front Compression Damping -18 Clicks AC/W Out (-1) Front Rebound Damping -7 Clicks AC/W Out (-1) ----------- ----------------- ----------------- New Nitron R3 Shock with Spring for 100kg Rider / (May 2018 tweaks) Rear Sag 14 mm Pre-Load as got (Standard) Rear Low Speed Compression -8 Clicks Out (Std) (go -1 Softer Touring) Rear High Speed Compression -8 Clicks out (std) (go -1 Softer Touring) Rear Rebound Damping setting -12 Clicks Out (Std). ——————————————————————————- My Original (Stock) MT Shock Sag Rear 15 mm, Pre-Load approx +1 & 1/2 Turns, Harder Rear Slow Speed Compression Damping, 12 Clicks AC/W Out, is Standard Rear Rebound Damping, 10 Clicks AC/W Out, is 1 Click Harder Rear High Speed Compression Damping, + 1/3 of a Turn In, Harder All good stuff

These settings are pretty much identical to the ones added to BJs long termer by James down at JHS. Truth be told, I got the settings from that video and wanted to use them as a base setting. However I avoided using their sag settings as setting static sag alone is a waste of time, seeing as the bike can’t ride itself. Static sag is only of any use to determine of spring rates are correct once rider sag is set. Since then I’ve realised the main thing I felt originally was the added weight on the front from sag being correctly set making the bike feel better. However the compression and rebound on the front were way off and didn’t work with the rear settings. They with too stiff and when hit with a gust of wind the bike would go into a mini tank slapper. When bouncing the suspension by hand after getting it warmed up on a run I could feel the rear rebound and compression was pretty good, but the front was way over damped and was too slow. Even when trying to bounce the whole bike the rear would move and the front would pretty much stay still, far too stiff. I’ve gone on to make changes to the fork rebound and compression. The bike no longer goes into mini tank slippers when hit by a side wind and the full bike bounces up and down simultaneously front & rear. I’ll keep tweaking here and there, as ultimately when it gets hotter ambient temps and the oil thins out I’ll need to add back some compression & rebound dampening. Oh, and I’ve also dropped a psi front & rear just to help generate a little more heat on these colder days as even this weekend it’s barely touching 10*c ambient. At the moment my settings are as follows... Front ForksRider Sag: 28mm Static Sag: 18mm (stock springs are too stiff for my weight) Compression: 15 clicks out Rebound: 7 clicks out Tyre Pressure: 35 psi Rear ShockRider Sag: 30mm Static Sag: 8mm High Speed Compression: 2.5 turns out Low Speed Compression: 7 clicks out Rebound: 4 clicks out Tyre Pressure: 33 psi

Why do you change your rear tyre pressure? Yamaha and all articles I have read state to keep your 36psi front and 42psi rear, for road riding. And to only lower on a track. Otherwise, I'll look into trying these settings myself, as I too find the front too hard when riding. (I'm also a 29" leg short arse and weigh 85kg fully kitted up.)
