Great vid mate. Got my 2015 duke a couple of years ago. Hasnt done that many kays since i got it though. Gotta sort the chain tension out tomorrow after i give it a nice oil clean. Was gonna use degreaser so cheers for that 🤣

Just adjusted my RC390 today for the first time! seems it was somewhat rather slack but all good now, luckily I've been cleaning and lubing it every month and a bit so hopefully lasts a while, will be subbing though rather liked your approach to doing things

My 2015 390 Duke owner's manual, under chain adjustment, states: "Lean the motorcycle on the side stand." The 5-7mm gap spec (also in my manual), then, is relative to the bike on the side stand, static weight being on the rear suspension. Contrary to the poster's comments, the chain will have LESS slack--i.e., a larger gap, by KTM's measuring method--when the bike is on the side stand as compared to a rear stand (which removes the suspension factor). For instance, on my bike, with my suspension setup, there is a 2-3mm difference in the gap when measured on the side stand vs. the rear stand, the gap being greater on the side stand--i.e., less slack in the chain. That difference is significant given the small 5-7mm spec range: if someone adjusts their chain to a 5mm gap when on a rear stand, the result could be an 8mm gap on the side stand, meaning the chain would be too tight! Moreover, the difference between measuring the gap from the main bottom surface of the swingarm vs. the bottom edge of the lip is about 4mm--also significant (almost double the spec range). So the measurement should be taken from the bottom edge of the lip to the top edge of the chain when the chain is pushed toward that lip.

Rear brake is hydraulic - chain and sprockets, rear wheel adjustment, these have no impact on the the rear brake. I would suggest that it's just a coincidence that you've noticed it - likely because you are paying more attention to the rear of the bike. Check how much pad you have left and your fluid level.

@MotoMirius

Hi, there is no rule as to how often - you need to do it when it needs it. Chain stretch is caused by wear in the link pivots and most wear is caused by lack of lubrication. Some argue sealed chains need little or no lubrication but I remain unconvinced. If the chain is going rusty or the chain looks bumpy instead of straight then it needs to be looked at.

I just took delivery of a brand new 390 Duke and the chain slack is seriously too slack. I read through the online manual and with my head still back in the bikes of yesterday ( and the day before) I just did not understand the process.

Cut a small block of something such as wood that will be the right size - I often just use a piece of card with markings that I hold against the swinging arm.

Hi there, this is a great video, but just to clarify, the measurement of the chain is done while the bike is not on the side stand but on the lifting gear, which to my understanding will drive the rear wheel downwards and tighten the chain? Basically, if I think it is loose while on the side stand, that might not be a clear indicator, as it is supposed to be 5-7mm while on the lifting gear. Is that a correct interpretation?

@MotoMirius

Жыл бұрын

Yes, rear wheel must be in the air, this is the point where the chain is under the most stretch - it is at the tightest position it will ever be when riding. So the measuring ensures that the chain will never be fully tight when riding - which places strain on the gearbox. Remember a little too loose is always better than a little too tight.

So you measure from behind the lip on the swing arm, or at the very front of that lip? Its a different measurement depending on which you choose and I've seen it done both ways.

@MotoMirius

Жыл бұрын

That's because KTM aren't very clear about where it's measured from - so people come to different conclusions

Hey David! The 5-7mm measurement for the chain slack, is it off the edge of the swing arm (it has a lip) or further in from the swing arm itself?

@MotoMirius

9 ай бұрын

Hi, this is a question many people argue about as KTM are not precisely clear - is it the bottom edge of the swinging arm or the top of the lip at the bottom of the swinging arm? My opinion is that this is not a good question - with a brand new chain, yes you can be very precise, but once the chain starts to wear you are trying to find the tightest spot and work from that - so the rest of the chain is looser and not to that spec, so the argument becomes pointless. Looser is better than tighter, so work towards 7mm and if you want to be very sure, do that to the top of the bottom lip of the swinging arm. Hope this helps! David

Hi David, I don't have a stand yet but should be buying one soon. Can I do a chain adjustment without it? I tried lifting the seat up to extend the rear spring and appears to be at max extension already. I've had my new bike for about a month now and the measurement is less than zero mm. I have my new torque wrenches ready to go.

@MotoMirius

2 жыл бұрын

Hi, although the spring isn't compressed, it also isn't extended by the weight of the rear wheel. So long as you've been putting lube on the chain you are probably still good to go as the dealer should have checked the chain. Good luck with your new bike!

Hello, found difficult to make out what you said. Was that motorcycle oil used to clean chain with brush? Additionally have you replaced the oil seal behind the front sprocket? Thanks for informative well presented clips.

@MotoMirius

Жыл бұрын

Engine oil to clean the chain. It doesn't have to be anything specific. No I haven't changed the oil seal because it doesn't need changing. I frequently see people advising that the seal should be changed - but in most case the 'leakage' is just the chain oil thrown off the chain. Unless you have a sunny Sunday only bike where you can use a dry type lube then you should have oil 'leakage' off the front sprocket - if you don't you likely aren't putting enough lube on the chain.

A common question. Unless you are measuring a brand new chain then it makes no difference since you will be measuring the tightest point, and the rest of the chain will be slacker. I recommend measuring from the underside as looser is always better than tighter and it is better for your chain and bearings life to err on the cautious side.

To the under edge of the swing arm where the chain would touch it if it were loose enough. A few mm doesn't really change much

The correct way is to measure from the top/underneath the swingarm like shown at 7:05? So I'm not measuring from the bottom of the side of the swingarm?

@MotoMirius

Жыл бұрын

Exactly how this is measured is the subject of much debate between owners given that the factory diagram is open to interpretation. Once the chain has a little wear, this discussion (as with what is best oil and what tyres are best) becomes mostly academic given that only the tightest point in the chain is this measurement and all the rest of the chain is looser. A little too loose is better with chains than a little too tight so I would recommend erring slightly looser and you can acheive this by measuring from the lip and not the bottom of the swinging arm.

Great video. Just a quick question. My chain when tightened to the same setting each side seems to be misaligned when I use a laser or straight edge. It also wanders more when running on the stand when aligned with this method than the laser. Any ideas why?

@MotoMirius

Жыл бұрын

It's not unknown for the markings to be misaligned. I tend to tweak the settings until I'm happy with them. There isn't any reason for the method to cause a change in the alignment but misalignment will be noticeable if you watch the chain running over the rear sprocket - and wear in the chain will make this more prominent.

@@MotoMirius thanks. I'll get a second pair of eyes on it. First time adjusting myself.

Just to make sure I fully understand how you're getting your chain measurement, you're measuring roughly 10-12 mm from the bottom flat part of the swing arm and 5-7mm from the bottom lip part of the swing arm?

@MotoMirius

Жыл бұрын

That sounds about right but - just to be clear, this is not valve clearances, chain tension is not in real life measured to the mm except perhaps when you have just fitted a new chain and sprocket set. Looser is more important than being too tight, so I will always err on being at the looser end of any measurement, so I advise not being too concerned about getting it exactly to the mm.

Thanks for the video. I might have missed something but I couldn’t get what the correct/acceptable length of 20 pins on the chain should be. 30.16 is bad and needs replacement, what would be a good/acceptable length?

@MotoMirius

4 ай бұрын

Misread your question at first. 301.6mm is the maximum length before the chain needs to be changed. If it's less than that then it doesn't need to be changed - obviously if it's close to that then change it. Given you would change chain and sprockets it's a bit expensive to change it before it needs it.

There are a number of different ways of lifting the bike. My preference is an Abba stand - largely because my rear stands are cheap and rubbish, but decent ones are used in many shops - its a fast and reliable way of lifting the back wheel. You can lift from under the bike, but you should remove the bottom fairing first. It's possible to lift it on the side stand by jacking up on the other side. With most lifts you need crack the rear axle loose and tighten it with the wheels on the ground - safety is important when lifting a bike.

Hi there, when you measure the 5-7mm are you doing it from the lip of the swingarm to the chain or are you measuring from the slightly higher part behind the lip?

@MotoMirius

2 ай бұрын

Hi, measurement is to the bottom of the swinging arm. The diagram can be confusing because the top arrow appears to point to the top of the lip - but the bottom arrow in that diagram points to the bottom of the chain - and it would be impossible to have 5-7mm clearance between the top of the lip and the bottom of the chain. But, it is important to remember that this is at the tightest point of the chain, not just a point in the chain (unless it is a new chain) and it's also important to remember that looser is better than too tight, so if you measure to the top of the lip, it will be better than doing it too tight. Hope this helps!

Because the swinging arm and the chain do not share the same pivot point, there will always be some offset which creates slack and tightness with extreme movement of the swinging arm. If you look at the chain on a dirt bike, it will always have more slack than a road bike because the swinging arm moves a bigger distance.

Does a loose chain affect changing gears? My chain keeps getting loose after few days after i tighten it? I notice when it gets loose because the shifting seems weird and i miss 2nd or 3rs gear at times. When i tighten the chain back up the i never miss gears....why does the chain keep loosening? I just replaced the stock one and its loose already after a week of riding it. I tighten it with the wheels on the ground. Is that wrong?

@MotoMirius

Жыл бұрын

Missing gears can cause shock loading on the chain, but most chain wear comes from lack of lubrication, so that shouldn't be an issue with a new chain. Gear changes should ideally be done with no load on the chain or gearbox so the chain would be mostly irrelevant to the change and the slipper clutch if you have one should assist - you might need to work on your technique a bit. But it could be that your issue is adjusting it on the ground - the tolerances quoted are for when the bike is in the air and the chain at maximum stretch - most bikes, the tolerances are for on the ground, but off road bikes need more play and KTM is mostly an offroad manufacturer at heart, so if you overtighten it then you can create stretch and you will damage the gearbox

It’s because your chain is worn. Links will seize making it tighter in spots which will tend to increase wear elsewhere. Most common cause is lack of lubrication.

You could use engine oil to clean it, I wouldn't recommend using it as a lubricant as it will get very messy as it will get flung off very quickly. Skäl David

To lube a chain correctly remove it. Put it in a small tray and add: Axel grease mixed with gasoline. Soak for 10 minutes then remove and let dry. Job done. It works well and piss on the o-ring BS. They are made of a rubber type that won't melt with petrol on them. Now the chain has good grease every where. Repeat every service.

When doing chain tension - do you measure off of the lip of the swingarm or off of the body of the swingarm? This is such a controversial topic in these bikes. I wish KTM would've just provided a limit for allowable "chain play".

@MotoMirius

Жыл бұрын

If we follow the KTM guidance exactly, it is from the top of the lip of the swinging arm lower edge, but I use the bottom of the swinging arm to ensure I don't overtighten the chain and in any case the thickness of the swinging arm lip is close to the chain play tolerance. But I don't believe the KTM engineers expected people to over analyse this or make it controversial since a chain will rarely wear evenly and guessing exactly which is the most tightest of the tight spots is pointless - internet arguments over this are between people who are not engineers. KTM have provided a limit for allowable chain play - 5-7mm. The only difference is unlike other manufacturers, they thoughtfully did so with the bike in the air so avoiding needing to drop it down onto the ground after every adjustment to confirm the measurement.

@affinitystablepeanuts

@@MotoMirius I'm still confused. When I set it to have an air gap of 5mm between the top of the chain and the lowest edge of the swingarm's lip - it feels too tight. It even makes screaching noise when I move the bike around if I set it like this. What actually feels more or less alright is when the top of the chain barely disappears behind the swingarm's lip if pushed up in a described location from the underneath. Which, surprisingly, is around 5mm from the non-visible surface of the swingarm..... I'm utterly confused here :-D Another internet battle is over whether the measurement is to the top of the chain or to the centre of the link 🤦‍♂

@@affinitystablepeanuts There are lots of internet battles - but none that interest me, and I won't get drawn into that type of time wasting. I assume you have the rear of the bike in the air and you are doing it at the tightest point on the chain. If yes, then you are setting it at the point of maximum stretch of the chain - at no other time will the chain get this taut. If when the bike is down on the ground you have a tight spot then you are doing something wrong, the chain is worn out or there is something else causing it. Bottom line - it's always better to set the chain slightly too loose than too tight, so if 10mm works for you, then set it there and that is the right setting.

@@MotoMirius cheers, David! I really appreciate the work you put into all this and the help of your channel. Please believe me I make no intentions to get you involved in any of online arguments! Rather just wanted to know your opinion on this topic. Very grateful for your videos, especially everything around 390 duke. Makes my life with this bike a lot easier :) Today I have re-done chain tensioning with the bike on the rear stand (as per manual) and I still have found that what feels like a correct tension is much less than what I get when tensioning as per 390 Duke's user manual. I totally agree with you on "too lose is better than too tight". So I have left it at that. In my case it's about only 1mm visible airgap between the top of the chain link and the bottom edge of the swingarm's lip, when the bike is on a rear stand and when pushing the chain up and looking from the side as per Duke Owner's Manual. Thank you again for all the informative and highly valuable videos and for finding the time to respond to my comments. Have a wonderful day!

You should always adjust then chain on the ground

@MotoMirius

You would be right on any other bike. But not this one - KTM specify that the bike is raised from the ground to measure the slack and make the adjustment. You can do it on the ground, but then you are not going to be able to use the manufacturer tolerances.

I just serviced my Bike at this dealer, I can barely tell they did anything at all and charged me almost $500 dollars. The receipt they gave me only showed basic checks but they claim they did every specified on the manual for the yearly service. I'm very skeptical of this.

If you've kept on top of your bike then you shouldn't find much difference in the bike from a service. The main spike in cost would be if they checked the valves as this is a time consuming job. I can't really comment on your service - there are great dealers and there are terrible dealers, I wouldn't take my bike to my closest dealer which is very close to me because I don't trust their work. These are reasons why I now do the work on my bike myself - it isn't hard to do so long you have at least some mechanical expertise and just work your way up to it. Of course if you have a new bike then selling price and warranty can make this a hard choice.

People have been cleaning chains with oil since chains were invented. I guess you've never tried it? Much better than using a detergent that will also strip out the oils and grease from the sealing rings and from inside the rollers, accelerating wear on the chain. Just because a detergent spray is quick doesn't mean that it is better.
