Thank you for this video. My gf needed her chain adjustment, and I was at a loss, having only adjusted Jap bikes. The camera work was fine-enough to get the idea. I don’t understand what all the negative comments are about. Thanks again!
I started with 30/30 on Q3's with a 750 up here in Seattle but found better wear with 32/32. This last weekend it was 100 degrees and had to take them up to 34/35.
Dave Williams here, the videographer. I've been filming Dave Moss for 10 years now and seen that time and again, increasing tire pressure to cope with rising air / track temps; even from morning sessions to afternoon sessions of the same day.
Williams again. Question for you. I've been wanting to do a video with Dave where we take a good tire, run it at the proper pressure, then change the pressure to demonstrate a cold tear, followed by restoring the proper pressure and healing the tear. do the same for a hot tear and some of the common geometry tears. Would you find that mildly interesting, interesting, or very interesting? thx
Hello, I have an s4r. I'm going to replace the chain and increase the rear sprocket by one tooth. I have an LT Snyder shop manual that says: "should the chain be replaced, the eccentric default position is at the six o"clock position in the eccentric. if you position the eccentric at the 12 o'clock position the chain will hit the chain guard." What and where is this o'clock adjustment? Thanks, John.
John - the eccentric is the way the drum moves up and down inside the swing arm. Move it one direction and you will see the top of the chain rise, so the other direction the chain will fall. If 12 o'clock is the high spot you can get a black felt pen and mark when the chain hits the guard as 12 or just a straight line. Move that 180 degrees back and you will have the 6pm location.
Dave Williams here, the videographer. No follow up unfortunately. At these track events, particularly schools as this one was, people get side tracked working on other things and don't return, particularly if the bike is working well enough for their pace.
So this can be done without a rear stand? I just got a S2R 1000 and the chain is a bit loose. Also, mind explaining a little bit about checking tight parts of the chain?
It can be done using the side or kick stand and with a helper. It is a lot more physical work though, so you need to see if you can (without stress) pick the bike up on the kick stand while the helper spins the rear wheel. Find the place where the chain s tightest or has the least amount of free play. I have many videos on this topic for you to watch :)
The tool is an ATV wrench that is easy to acquire: www.ebay.ca/itm/Motion-Pro-Shock-Spanner-Wrench-Showa-Mono-Honda-ATV-200X-250R-350x-P529/401429318589?hash=item5d770d4bbd:g:wskAAOSwA3dYTziU&vxp=mtr
I've seen fabricators do amazing things so I am sure there are many who can do that in their mind. The question becomes is there anything small enough as a single sides swing arm that would fit that doesn't weigh a huge amount.
Dave Williams, editor, replying here. Sorry for that. Between the tire, the chain guard, and Dave Moss working at warp speed I couldn't get a clean shot of it. But there is a sprocket / castle nut looking gear in there on which you use a C-spanner, like you would on a rear shock castle nut to adjust preload.
Isolate the tight spot in the chain first. Put someone much heavier than you on the bike (or 2 lighter people) and see if the chain still has free play in it, normally checking the bottom side. With two riders there should be .25 of an inch of free play. Remove the rider(s) and roll the rear wheel checking tension as you do so. If the chain suddenly gets very loose, replace the chain. If there are multiple tight spots, replace the chain.
I wasn't aware that adjusting chain slack required a person sitting on it. I thought it could be checked while the motorcycle is on a rear paddock stand. Can you clarify this point? So far this is what I jot down from your instructions/video: 1) Find the tight spot in the chain which is typically the middle point between the front and rear sprocket. 2) Stretch out your chain by adding compressing the suspension with a heavy rider 3) At maximum stretch, the middle point of the chain should have 1/4" travel up and down 4) Not sure about rolling the rear wheel and checking tensions instruction here Thanks!
It can, but doing the adjustment with riders in place just makes it that more accurate. The tight spots can be random and there can be more than one. Turn the wheel 90 degrees and check the chain again. Do that through the entire length of the chain.
Hey Dave, be more gentle to the wheel and paint pls. it hurts my feelings, even if it's not mine. btw would you like to hire foreign technician to help you out around ? :)
Thanks for the comment, point taken. I do not have anyone working with me, and as there is not very much income I cannot afford to hire someone to help.
Getting them started on one small task is the trick. Checking tyre pressures weekly is a good start along with checking/cleaning a chain. If the hook can be set and they are not too intimidated by tools, other tasks are adopted. It takes the "Pay it forward" POV to inspire someone to get started!

Great info. Thanks Dave. I just got one of these s2r. Now i know how to do it.
thank you sir,i had no idea how to adjust it on my single sided swingarm bike,on my dirt bike its obvious with two swing arms,thank you :)
You are welcome, and please pay it forward with others who may not know and be in the same situation you were in. Thank you.
Dave Moss Tuning I definitely will :)

That would be very interesting and a great tutorial! Something everyone would need to see and learn.
Thanks for the feedback- we will try to schedule some time for that this summer.
where did you find the adjustable span wrench showed in the video.. also, great info.. thanks
Yet another excellent video Dave, thank you.
Thanks a lot mate, easy to understand video and also looks like you answer to comments. Appreciate it.
Always try to answer comments as that will help the viewer who can then help others.
Are those 2 bolts done up to a specific torque?
Yes - see your service manual for the torque specs.

Do you have a follow up video?

Dave Moss Tuning Well keep them coming, love your videos!
any idea what model Ohlins shock is on this bike?
Hopefully someone will share that information. I will be a variant of the STX46
So this can be done without a rear stand? I just got a S2R 1000 and the chain is a bit loose. Also, mind explaining a little bit about checking tight parts of the chain?

I am looking for the video on. Chain tension and I can't find it
Great video! Thanks!
Thank you for watching!
Where can I buy one of those tools for my 2007 Triumph speed triple?
The tool is an ATV wrench that is easy to acquire: www.ebay.ca/itm/Motion-Pro-Shock-Spanner-Wrench-Showa-Mono-Honda-ATV-200X-250R-350x-P529/401429318589?hash=item5d770d4bbd:g:wskAAOSwA3dYTziU&vxp=mtr
Dave Hello,
I've been looking for this chain tool around, I found them as Hook wrench. but what is the correct mm of it? 50-60mm?
thank you..
Chain free play is normally 50mm to start. If you use all the travel in the shock, more than 50mm is appropriate.
Can we install single sided swingarm in duke 390
I've seen fabricators do amazing things so I am sure there are many who can do that in their mind. The question becomes is there anything small enough as a single sides swing arm that would fit that doesn't weigh a huge amount.
Oooooo k. Then thanks for giving your time
Ok then , you have good knowledge about it so please find out which swingarm is suitable for 390
Having looked around, they are all on big bikes which will not work. Far too heavy.
The camera did not show where that guy placed the tool to tighten the chain. He was focused on the back tire
Dave Williams, editor, replying here. Sorry for that. Between the tire, the chain guard, and Dave Moss working at warp speed I couldn't get a clean shot of it.

Totally agree. The most critical part and it's missed in the video.
It wasn't clear when you know it is tight enough. You mentioned 1 inch I think. How do you know a chain is tight enough?
Isolate the tight spot in the chain first. Put someone much heavier than you on the bike (or 2 lighter people) and see if the chain still has free play in it, normally checking the bottom side. With two riders there should be .25 of an inch of free play. Remove the rider(s) and roll the rear wheel checking tension as you do so. If the chain suddenly gets very loose, replace the chain.

Lube hot, adjust cold, ladies.
Wow, so i can just use a front stand and keep the bike straight while adjusting the chain? Heck yeah.
"Air cooled" Yeah, he knows.
Are you making fun of my cat Mr Moss?
I can't believe how many people own a nice bike have all riding gear but no nothing about maintenance. Read your manual, buy a service manual learn.

worst camera work ever.
I look forward to your version of this topic to comment on.
