Good advice. Here's a tip that works on some bikes. When you have your bearings out of the linkage and swingarm, drill a hole and tap it to put a zert fitting in. Grease everything up, put it all back together like normal. If you ride a lot, give them a squirt every few months, casual riding do it once or twice a year. Your bearings will last a lot longer. You have to make sure that the placement of the zert will not interfere with anything. Ride safe my 2 wheel friends.
From Wikipedia: “A grease fitting, grease nipple, Zerk fitting, grease zerk, or Alemite fitting is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.”
I wish I did that when racing XC in wet conditions. I did proper service or course, but pumping out the water from the linkage would have save me lots of time.
One thing about the chains, remember that a chain derailment is what broke Malcolm Stewart’s femur a few years ago in Supercross. He was in the whoops, and the chain came off, and he went over the bars. Keeping your chain and sprockets in good shape is super important. And especially if it’s just tightening or loosening the chain, it’s one of the easiest parts of the bike to maintain.
All great advice. Chain maintenance is super important and it’s the first thing I do after every race. I never wash the bike with the chain on. Never. For non-prong chains, Pull the chain off and drop it into a pan of kerosene. Leave it in as long as you want. Next wire brush the entire chain. Next, wipe of with a lint free rag. Then use compressed air to blow off all residual kerosene from between the links until no more kerosene can be blown off. Now spray between links with WD40 to ensure no residual moisture remains. Put the chain back on and apply your favorite chain lube and adjust per manufacturers recommendation. Your chain and sprockets will last and last. More importantly, there will be much less performance robbing chain rotating resistance. Especially important on 150’s or smaller.
Long time road rider, newbie dirt bike rider: wow, packed with information. Bought a 1999 Kawasaki KLX 300R for some easy dirt bike riding on local trails (no crazy speeds or jumps). All the same, much food for thought!
WOW, thank you so much for this amazing information. This is one of the best and most informative video I’ve seen so far. I just bought a new 2023 CRF300L and I’m looking forward to performing the maintenance you describe.
Little tip my fellow riders When packing needle bearings in your swing arm and linkage use a collar and put it in just enough so that you can pack the bearings without ever having to worry about the needles dropping out as really tacky grease will pull them out of an open bearing cage.
Another point to add on, ignoring his advice and only replacing the chain or sprocket one at a time will wear them down quickly. Old chains wear out new sprockets, old sprockets wear out new chains.
bearing maintenance: If you race check them often, esp rear suspension. When my son raced I took the bike apart every 3 weeks or so and was Surpised at how water can get into everything. And I use a lotta grease
I have been riding dirt bikes for decades and only recently learned this little trick for air filters. It's a nasty process to clean them, unless, you use Wesson Oil! It works great and can be easily cleaned using dish soap and of course is safe to throw out on the ground.
Not been riding as long as that but have you tried no toil because I normally use the cleaner in a bucket quickly get a lot of the bits off then put the filters in washing machine with the cleaner and detergent and they come out like brand new but as far as I know you gotta use the no toil air filter oil but it’s all biodegradable
Thank you for a good video. My concern with blowing the bearings with air after a wash, is that I’ll be blowing the water into the bearing? I like the idea of blowing air into components like the engine kill switch but I have concerned with blowing air onto bearing area…. Is it not better just to let the bearing outside dry by itself?
Hey Rado, thanks for the great advices! One question, I've got a PAPER air filter on my 4-stroke, is it really maintenance-free and when does it need to be replaced?
I was told many years ago in my mx racing days to never "squish" your air filter when oiling/cleaning it due to damaging the fibers? Any logic to it in your opinion?
Rubbish, you have to squeeze the filter to work the oil into the fibres and also to remove excess oil. The thing you shouldn't do is twist the filter as that will likely tear it, always squeeze.
i have recently brought a 2015 250exc, my first 2 stroke and i love it, im just wondering about the top end, the guy i brought the bike off said he done the top end 20 hours ago and i’ve almost done 40 hours on it. Do you think i should do the top end or how many hours do you recommend to do the top
250-300cc can last up to 200 hours plus if you are not riding them super hard. Being your first two stroke and it's size. I wouldn't worry about it for some time to come. Look up how to tell when your top end needs a rebuild. I'm sure there are some very informative videos on the subject. Being raced they can go about 50 hours even less with some riders and other get more. Depends on how they are ridden. And there are ways to check so you are not wasting money on things that don't need work. Comprehension test is part of the testing and removing the expansion chamber so you can look in the exhaust port to see if there is any wear on the piston and bore that you can see. Sticking your finger in and rubbing your nail in the bore to see if your nail catches any grooves. Also if the cross hatching from the hone stone is missing. That's a good sign that it was or wasn't done 20 hours ago. Look up boring and honing a bore and you will see the cross hatching I'm talking about so you know what to look for. Use a torch to see it. Proper maintanence cleaning air filter will help your top end last a lot longer and propped checks during servicing will save you a lot of money and help you learn what to look for when you buy second hand bikes. More you learn the more you will save and enjoy riding them not spending on them. I wouldn't buy anything under a 250 two stroke because they don't have the same long life span.
This video says: "Spend as much time working on a bike as you you do riding". If bikes required this, there would be a lot of manufacturers out of business.
I’m running about 25 hours on my 2024 tc125 and I do the air filter every ride and change the oil every 10 hours. How long do you think until I need to rebuild my top end?
I have 25h on 22 YZ125 and will be doing the top end soon. what does Husqvarna say for your bike? I would not go more than 30-40.. depends how you ride
Thank u for the great advice just got a 91 125 2 stroke I'm happy to be able to restore and do maintenance to make it last forever thanks for the heads up on everything I need to make sure it runs great!
Rado got 2005 Ktm 300 mxc. Haven't u said before I can use that shellrotella oil in my gear box. What weight should I use exactly what is your preference?
Nope I replace my bearings about every 120 hours. About the same time I do my bottom end and crank bearings I do a complete bearing change on whole bike.
I mean if yamaha quotes in the service manual to change the oil every 7.5 hours. Im sure the engineers have looked at those oils and they arent that dirty or broken down until 7 plus hours. Is four hours really necessary?
Depends on type of engine. The primary issue isn’t so much wearing out the oil by a process referred to as “shearing” or degradation. The oil stock will likely be good for far longer than even 10 hours or more. Most of the time the oil goes bad due to fuel dilution before it is completely sheared or broken down. Fuel dilution time really depends on the engine type. A higher strung motocross engine is going to let more fuel by the rings on the piston than an air cooled trail bike engine. The reason is that motocross engines tend to use one compression ring and one oil ring. Trail engines use multiple rings, sometimes even as many as 3 and one oil ring. Less piston rings, smaller piston skirts, higher rev’ing, higher compression all mean it will tend to shorten oil life. But again, oil life often doesn’t only mean are the base stock oil good. Fuel dilution, shearing action, contamination, efi vs carb, riding style, even air filter condition will impact the serviceability of the oil. Instead of discussing engine oil changing life, I’d prefer to discuss fuel/oil ratios and best way to tune a power valve, 2 stroke life!
i got an sx 150 wth aprox 50-60 hours on it and i haven't noticed a change in performance. I don't race, but it's at high rpm a lot of it's life and it takes it well. Although it is a two ring and you could probably push one of those to 80 then do the top end.
Along with removing the swingarm and greasing bearings, also remove and lube the axle blocks and adjuster nuts and bolts going into the swingarm. Don’t wait. You’ll thank me later.

Hey Rado, thanks for the great advices! One question, I've got a PAPER air filter on my 4-stroke, is it really maintenance-free and when does it need to be replaced?

It depends on howe you use it. Riding it on a motocross track 4hr is defendeble. Riding in the outback make often oil charges not necessary.
Depends on type of engine. The primary issue isn’t so much wearing out the oil by a process referred to as “shearing” or degradation.

might be doing top end this winter, gut i'll definitely change the coolant@@Idk56373
Blowing compressed air at water just forces it in the bearing. Better to just dry it out with towels and some WD40 to displace.
Good Advice.Thank you very much 🙏
Bewel Bar for the swing arm. Easy maintenance.
