A very effective trick that was past on to me long age and made brake bleeding quite simple is on the bleeding hose as close to the bleeder valve as possible is to make a small loop using either tape or cable wraps then the hose being held in a reclaim bottle. This creates kind of an air lock and once you fill the loop with brake fluid there no way far air to get sucked back into the calipers. This way you can open the bleeder valve slightly ( just enough to pass fluid, too much and you'll suck air around the threads on the valve) then use the multiple pump method just take your time and keep the master cylinder full as you go. This should help when pushing the air in the over the fender line not needing to stop and start bleed process, keep pumping keep adding fluid until you've pumped several ounces ( more than enough to flush the entire line). The lever will feel light until you close the bleeder valve then it'll be firm. Bleed from the farthest point from the master cylinder and the entire line is bled. Works every time, easy least!!

Buonasera, a quanti Nm viene serrato il bullone che regge il pompante?

Does this work on 200 ? I have parts available from the Adv 390 2024 and duke 390 2025 the gen 3 one. Which one fits the duke 200?

What the part number on this ? Is this the same one available on adv 390 ?? Edit : For the 200, can i use the one from adv 390 or duke 390 ??

Hey David. What kind of tool is that for pulling out the bearings? The tool you use at time 03:40? If possible please send me a link. Thanks a lot ... Ralf

If that’s stainless steel for £630 they fk right off 😂

Tenho uma bandit 650 carburada ela esta fumando , preciso do jogo de aneis para ela mais aqui no brasil é quase impossível, como vcs chamam aneis de seguimento por ai pode me dizer para eu tentar importar desde ja obrigado

I tried squeezing the brake a little to see if any air bubbles show in my brake fluid reservoir but none appeared and my brake pads don’t want to grip onto the disc - I also fitted a new calliper

Will this work for 390 Adventure ?

i’ve just got myself a WP apex rear shock off a husky 401 for my Duke, instead of hacking the original swing arm to enable adjustment would a 2023 390 duke swing arm fit my 2018 model year?

Hi David. It's been a while since you published this very helpful video. I was wondering if you've gathered new intel that could help me make a decision regarding a piggyback ecu. I am between the Rapidbike Evo Exclusive and the Coober. I want the auto tune capacity that these offer. My mods are an airbox lid and mini cat delete. Currently running a Fuel X Lite, but I have a feeling my bike is running lean. Lot's of popping on decel. Coober seems to be easier to install which is always welcome. Please let me know if there is anything you can add to help me make a decision. The price is very similar here in the US, so that's not really an issue. Cheers!

Quality video welldone, may I ask where did u ordered the 50 sprocket from? I have an orange one for my rc supposed to match but the 6 attachment holes on the sprocket seem further apart then the standard 45 already attached, is there an size adjuster that could be brought to make it fit hmm?

Thanks!!

What size is the saw, 40 mm??

I get hul failure on duke 125 goes on and off what do you think the problem is ?

To move the Pistons back on the caliper you should first remove the lead of the container and then you could move back the Pistons easily...

where do you get the tank sticker to cover the shiny finish? its so annoying to keep it scratch free

Hey, just to confirm you are putting your scale BEHIND the little lip that’s on the swing arm to take the dimension right? I’m going to measure off the big main flat surface

Hey @motomirius. I have a problem in my 2018 390 duke. When the engine is cold, pulling in the clutch makes a rattling noise from the engine(from the clutch basket)After the engine heats up, the sound dissappears. What could be the issue? I've already changed the clutch plates that didn't help:(. Pls reply

Thx bro😊

Is the 2023 duke airbox the same as the rc390 air box Also need to know if the duke wiring loom is the same as the rc if you could help out with some info that would be grate

Can you show a video on ignition lock set change for the 390?

Sir what is the size of hole saw.Please reply.😢😢😢

After installing fuelx lite Does this create a problem while checking pollution of our bike ? No one has talked about this

Hey, is it possible to install these WP Apex on KTM DUKE 250 2018 INDIA version?

I like to take saturdays or sundays to go over the bike like this(learned a good few extra steps I wasnt aware of here) aswell as wash it over and remove the layer of squashed insects thats accumulated over the week.. Before I ride I always look underneath first to check for oil and fluid spillage, I then step on the tires to check pressure(obviously not an accurate reading, but when it is the correct pressure almost all the time I do notice if its off after having done it everytime), I get on the bike and turn on it on, then I check the lights, breaklight and signal light, lastly check the breakes by making sure they dont give when I squeeze them. All in all takes 10-15 seconds extra in the morning before I start my commute to work.

Nice informative video👍🏼

Still making use of your “how to” videos. Invaluable as far as I’m concerned. In order to know your bike you have to work on it. Cheers From KwaZulu-Natal South Africa

How many ml?

Sounds like a stupid question but I'm trying to find the main fuse for the exact bike here this is a great series thank you for what you do I'm downloading it right now and God bless you Godspeed You wouldn't believe the problems I was having with the battery change and I'm part Grease Monkey ,laugh my effing ass off!(lmfao)!thanks!😆😅🥰psHey, hey since I brought up the battery whilst I was struggling finding the right bolts and tightening them down with all them damn words that were on there on the positive side I sparked at a couple times hitting it with my brunch don't you think that that's probably why now all the sudden my bike is just completely dead because I blew the main fuse I mean that's my guess I hope that's what it is I just can't find the damn mean one I found it one on the compartment side that holds the spare ones I think they're spare ones but I'm looking for that mean big one mean not mean stupid microphone sorry thank you God bless godspeed too haha

For duke 2016 model.. How do you turn it off?

Awesome piece of info. Thank you

Можно вопрос не по теме видео? У вас есть видео как прменять топливный фильтр. На других каналах видел там снимают бак. Без снятия бака нельзя заменить фильтр?

You mentioned Oilfilter Service Kit. It comes with a screen.

Can you please share the part number for the shock?

I there any problems will I remove stock decat. And install a moded one

i watched tons of videos about moto maintenance and this channel - it is just how one MUST make this videos. IMO it is absolutely the best channel, actual videos how to do things (not "you should do it this way comments" - cut - montage - next scene, like in avengers), fine details on how to do things, tips/hints, caveats.. everyone who own a Duke 390 - you guys are lucky because David does and because David decided to publish these Duke-series about improvements and maintenance. ps: I'm not a noob, in childhood a owned several crappy-motos, and i was able to disassemble it down to bolts (including the engine guts) and assemble it back in a day. but these videos is a thing

If I have a slip on exhaust/muffler on the bike with the coober intake is the bike gonna run too lean or do I need a piggyback or ECU re map?

Is there auto mode for pro version, which can put it in a state where it behaves like lite? But if user wants to play then use pro side of things

What did happen next?

Does the XL1200S take the same rebuild parts as a standard XL1200? Not sure what parts to order for a complete rebuild...

As always a quality “how to”. Nice work.

I found changing the spark plug from a flat electrode to a pin electrode made a significant change to the low rev range..much smoother.

Is 1st gen RC outer pipe cover(fork) same as Duke?

Hello I just recently came across your videos and they’ve been incredibly helpful! I wanted to ask if you’d have any recommendations on getting my 2022 390 duke to pop wheelies , I know the new models can out of the dealer but mine has a slightly smaller displacement, if there’s any modifications you can recommend it’d be greatly appreciated!

Top man thanks for ur up loads 👌

En español como se podría traducir 🥺

I don't see any reason in can't be sped up by flicking or tapping the hoses to get all the air up that might be sticking to hose walls.
