I'm following this video to take my tire off so I can bring it to the mechanic and get an inner patch done where a nail went through. When I put it back together and put new grease on everything, does it need to be lithium grease on all of the parts that I will be re greasing.?? I'm doi.g this on the RC390 not the Duke
Ah, the grease debate! Personally I use a general purpose grease for this, but lithium based greases are becoming more popular for general purpose use - check the description on the grease as some are more specialist.
@Moto Mirius okayy I'll check them out. I'm bringing the tire to get an inner patch/ plug because of a nail (in my month old -300mi use tire 🤬). So while at the mechanic I'll ask them what they sell, or at least use
Your videos are on point. I learn allot from watching. And I really appreciate that you are very thorough. I have learned allot on how to do my own on my bike.
Thank you for this video, I got a flat tire and needed to dismount the wheel, it was very useful to get your instructions ! Personally I didn't need to tinker with the chain tension setting at all
I've recently reorganised my KTM videos so the maintenance videos are now all in the same playlist as they were getting hard to find in the modification videos. But there are still more to come!
Great video! The only thing missing are the socket and wrench sizes. Thank you for help! Now I can get my wheels off for new tires. I haven't ridden since I got a flat in August.
Glad I could help and well done! Sometimes I do put the socket and wrench sizes on. There are several reasons that I don't as a rule, but the most important is that the cheapest way to buy spanners and sockets is as a set, and I've found that putting the sizes on leads people to buying them individually - and I'm still using the same spanner set I bought nearly forty years ago. If you need to know a spanner or socket size because you are missing one that fits, just measure across the flats of the nut.
I successfully taken off the rear wheel however whenever I attempted to put the wheel back on I cannot fully tighten the axel bolt because it tightens the rear wheel to the point it will not spin freely also makes the rear breaks feel funny
Yes, I have had that happen. You just need to make sure that everything is properly in place with the spacers in the right places and then it will tighten up properly.
Hi David, greetings from Brazil! Your content ia absolutely rich and I am learning a lot. Thanks for share your knowledge. I have a question regarding the TFT display. I didn’t found any video related that and I believe that you faced the same issue that most of us: fog in the display. Do you have any tips to solve or minimize that? Also, could you prepare a content regarding that? Thanks
Thanks and hello to Brazil. Fogging in the TFT is not unique to this bike or even KTM. The TFT is not airtight so water can enter even as moisture in the air on a damp day. I don't think KTM have solved this even with several years of trying. I find there is can be a little water after riding in the rain, but it dries out when the weather improves. I have added it to my list. Thanks
@@ahmedk7815 A lot depends on tyre design, this one is quite flat with very short sidewalls so it gives a good contact patch. 150 is a typical stock tyre size.
Hi, what wiring and sensor issues are you having? Being at high altitude changes the fuelling requirements and makes changes to the bikes such as exhausts much harder.
@@MotoMirius I mean like starting problem, missing problem, battery charging problem, no headlight etc with problem explanation, proper diagnosis process and solutions at all.actually am not having problem but being a mechanic we need to be updated regarding these current issues....anyways thanks for your kind reply
Hello David, I have a 2015 RC 390 and it ran 16000KMs, Chain and sprocket not changed yet. recently when rotating the rear wheel, the chain clatters hard on the swing arm, i have tried to matched the spacer alignment to almost identical, yet there is a wavy pattern in chain motion. The chain gets really tight on part of rotation then comes back to normal. Changed the bearing recently, yet its same. Any idea ?
Sounds like it's time for a new chain. It's normal for old chains to have stretch in some parts and tighter spots elsewhere. Check also that the rear sprocket is not bent - but if changing the chain, sprockets should be changed at the same time.
hello Just to clarify, did you lubricate a lithium lubricant with a temperature range of -30+120 degrees? self answer) manual indicates "Bike Grease 2000" as lubricant for these parts of the rear wheel. its range is -30 +120 degrees
The function of the grease here is to allow the parts to slide together without damaging the coatings and it helps to prevent corrosion. The rear wheel has bearings which do all of the work - there is no friction on the axle creating heat.
hello moto mirius!!!! Can u tell me why a ktm 250 duke sometimes downshifting at low rpm stalls (only when the clutch is kept pressed)? Thank u very much
In my experience this happens when the clutch lever isn't pulled in enough (or not adjusted for clutch wear). The engine is designed to rev very quickly and also engine brake very quickly - Ready To Race. The problem with race oriented engines is that they stall very easily and are very lumpy at low revs. There are two solutions, which apply to all race engines - make sure that you pull the clutch in enough and don't run the engine at low revs - it isn't designed for it. Ever see a supercar in slow traffic? They don't flow with the traffic, they rev the engine and accelerate then brake heavily, then repeat. I have often stalled the engine under heavy braking or when trying to pull away at low revs.
Hi, it's an odd error to have pop up if all you have done is unplug the display. Could you have pulled the harness and disturbed another plug? Otherwise you might need to visit the dealer to have the code reset. Good luck with that.
Hey David, Best wishes for the new year! Had few questions: 1. What's the best way to align the rear wheel to avoid any wear & tear of the tyre? 2. Can I use silicon grease instead of lithium?
Hi and thanks. There are a number of ways to align the chain - KTM recommend using the marks provided for this purpose on the rear axle. Lithium grease is designed for lubcricating steel and mechanical parts. Silicon is for rubber and plastic - it does not have the mechanical strength for steel parts. Lithium is not ideal for plastic.
Seals that go on the axle come in contact with road grime, oil and hazardous chemicals. They're generally made of nitrile . Same with fork seals as they see oils and sometimes fuel. They're nitrile too. Lithium grease goes good with nitrile and neoprene. Silicone is generally used to natural rubber. We don't use natural rubber seals anymore because they would go bad within very few months. Here's my two cents! Cheers.
Hi David. Genuinely blessed to have come across your channel. I recently got a duke 390 and I've learnt so much from your tutorials and videos. Keep it up 👌 I have a quick question. What size is the nut you have to torque to 98nm? I'm trying to order a torque wrench and I want to make sure I get the set with the correct socket for it. Thanks!
It is the stock tyre size yes. Different brands will sometimes have different profiles and different brands have been fitted as stock over the years. This is a Bridgestone.
@@borky1987 160 is typically the biggest and user reports are that handling starts to get worse. Bigger than that and you risk it coming off the rim - assuming you can even get it on in the first place. I've heard of people fitting 170 but it's hard to know if they even ride the bike or just want something they can park up.
The purpose of the grease is mostly to prevent seizure and corrosion - it doesn't have to be a high performance grease - all the work is being done by the bearings.
Just like Tatro but without all the moaning ! mind you he's calmed down a bit since he's moved shop and doesn't have to deal with all the "dumb ass" customers 😅.. Good precise video David , peace and Love brother 👍🏻☮♥️

@@MotoMirius you have the 50t stunt sprocket if I remember correctly? I was going to get that but I think I'm just gonna stick with stock gearing.
