Quick tip! Usually after the lock nut is off you can grab the spring and spin it. For me it's easier than the punch. Great video!!

When making adjustments it is a good idea to have the rear wheel off the ground, doing this takes some of the spring pressure off the preload adjusters which makes them easier to turn

a million dam suspension vids and finally one that is straight forward and simple, thanks

I loved this. I am a suspension tech for a living....I couldn't find a single thing wrong with this video. So, what I'd like to know is...Why the 91 thumbs down??...Hmmm.

Absolutely great video dude! very in depth, gets straight to the point and makes it as simple as It can be. Keep it up guys! I watch this Channel quite a lot and I’m refreshing my mind a lot on these vids as I haven’t ridden dirt bikes in years! ❤️

Great vid on Sag! Can you make a vid on how to choose the right shock spring for your weight? And a vid for fork spring spring for your weight? You guys are awesome! My riding has greatly improved from your vids! Bike set up is HUGE important regardless of riding level! Thank you!

[paultselembis]

The rocky mountain vids are so good!! Thanks guys!

I know this is old but thanks Chase and Charles for the tip and tech information. Along with you two and my manuals, I can’t go wrong. 🤞🏻👍👊🙌🏼

This is the best video and explanation of setting sag. Great job!

[christerstefansson]

Setting the sag with a new bike after brake in are i very importent. I didnt know that and my static sag (on the stand) was way wrong, i needed to tighten the spring 2 full turns in and it was a different bike to sitt on after that, way higher in the rear, and the shock suddenly started to absorbe the bumps.. Big big differens.

Good video... YOU DID GREAT GAVIN! I loved how excited Gavin looked. 😁

Best video yet on this subject. Excellent instructor.

On KTM's just loosen that bolt and use a preload tool like the ohlins one that old KTM's used to come with. I have a few laying around from old bikes that finally came in handy! Thanks for all these videos and info, you guys rock!

[bkennedy]

Would you need to adjust your forks to match after adjusting your rear shock?

[BikerBenny]

I just overhauled the rear shock on my xr650l with a stiffer spring. Is the bike sapposed to have any sag unloaded??

After getting off and only when put on the kickstand I slowly see it rise to fully extended, the forks do not

Ahhh I see 9:20 static sag

I do this alone..I have a Honda a measuring tool with a wooden ruler and an aluminum one..Slotted the wooden ruler and drilled two holes in the aluminum ruler..you can figure out where easily yourself, each bike is different..use two carriage bolts (1/4) washers and wings nuts..lube it the longer rack bolt (which is where honda manual says is the point to measure from) for the top and a bolt with tape wrapped around it to fit inside the hollow axle(manual says at the lock nut at the adjuster, not enough different to matter 1/8?) notch/slot the top and bottom of your new ruler to sit on the bolts..hook it on the bolts and lightly tighten-so they slip easily but not it in on a stand to measure the longest dimension..then take the bike and lean the bar end against a wall or in my case snap-on tool boxes sit on the bike, the ruler will compress in length..bounce on it a bit and let it settle....reach back and tighten the wing nuts. Get off the bike and put on side stand..now you have the longest and shortest.. dimensions and can adjust accordingly....cost...less than $5 and 1 hour labor..A note...You will get different dimensions each time you measure...sometimes as much as 1/2” ..being as consistent as you can will help, but it wont make the numbers Exactly the same each time...if Im within 1/8” I think Im good..

Love the video, wish you had a shop closer to where I live. Took my newly acquired "mint" 85 XR350R to my local shop to setup up suspension for me. They told me to drop off and pick up at certain times. Told me I didn't need to be there or even ask me my weight. No thanks..

[marcoluoma]

Thanks for this. The descriptions and videography were really clear.

[illwil]

I bought the motion pro sag 2 tool. The measuring tape can be really inconsistent. The video helped a bunch.

Question: on dirty bikes the static and rider sag need to be checked/adjusted only on the rear shock? On sports bikes need also on the fork.
