- This 150SX needs a new crank and piston. Lets dig in and bring her back to life! Will be the same for most of the current KTM, Gas Gas, and Husky 125's and 150s. Enjoy!

You have an absolutely great channel, in depth explanations on procedures. Anyone interested in working on motors especially young folks should definitely watch you. And old farts like myself learn different procedures on engines I've never worked on.
Snap-on makes a great ratcheting palm driver for doing case bolts or other lightly torqued bolts. Great channel keep them tutorials coming.😃
Thanks! Will have to check out that snap on tool. Thanks for the kind words! I'm a old fart too anymore lol. Recently had to start wearing glasses to work on bikes, didn't ever see that coming lol
great video,dont even have a ktm but watched anyways,explsined everything amazing and put in detail,would trust u fixing any bike,keep up gr8 work
Thanks, and thanks! Appreciate you coming along for the ride.
Same for my, I just watch and listen in my free time
Those are super cool little bikes
For sure. I love the small bore 2 strokes. So much fun
really helping me with my rebuild thank you so much.
Right on! Glad to hear its helping. Best of luck and let me know if any questions come up
Another great video!!!
Thanks!😊
Does KTM use a billet shift drum? Looks different from the shift drums I see in the Japanese bikes.
Hello. Yes its a aluminum shift drum on the KTM's. Its light, but it does wear quicker than the metal ones used on the jap bikes.
The marks that show where bolts have beenbefore are called the witness marks.
Yes sir
Awesome content as always!! How did you do at FTR? I saw you headed towards the race on your bike couldn't catch you on foot to say hi!! My wife was like stop running fool lol!!
My yz250f just quite at like 10.5m first lap. I think my bikes need you in their life's lmao!!!
Ahh cool man! Small world for sure! I did ok, first time racing in this class. As you know it was a little tough, people where going down everywhere lol. I did my best just to just make sure I had no stalls and no falls. And I accomplished that. Was up to about 9th place from a dead last start. Wasted way to much time in the pit getting fuel and lost some positions like crazy, ended up 13th. . Oh man bummer on your YZ250f not finishing the race. Do you know whats wrong with it? Did you get it up and running yet?
@UpAllNight91 Awesome job man!! Bodies everywhere lol!! So much fun though! First Sunday race for me as well,did 250c. Haven't got into her yet, but that is the plan this afternoon.
@@danielyoungblood101 oh yeah, people down everywhere lol. I probably seen over 40 people go down lol. I have done a lot of the Saturday sportman 2 races, this was a first Sunday for me, since they don't hold sportman anymore. I'm more of a track rider but these hare scrambles are surely challenging and fun. And lots of skills to brush up on. Hopefully you get your bike back up and running well. Do you know yet what caused it?
Awesome video! Where do you buy your parts? KTMs seems to be harder to source engine parts for than others. Thanks!
Thanks. I usually buy the KTM parts from Rockymountain ATV or Motosport. And you are right, sometimes they are hard to find, out of stock, or on back order.
Where do the forks go in transmission
They are above the shift drum and below the gears. Did you get them out of order?
Hi could you let me know what rpm you power valve open how fare the screw is adjusted on left hand side of exhaust valve flap behind the Christmas cover
We currently have the power valve adjuster screw at 2.5 turns. Turn it counter clockwise all the way, then turn it clockwise 2.5 turns. Thats where we have it at.
Thanks for replay buddy is this adjustment for that stator sidepv adjustment or for the power valve auxiliary screw next to water pump
@@kevincowley7111This is on the clutch side, right side next to the water pump.
Thanks you so much for you help bud is there any chance you could let me know the length on the other side also on how much it’s limited to open out with the little adjuster screw if you could thanks
@@kevincowley7111 Sorry for the late response. I will check that when I get out in the shop in a little bit.
Did you miss out the oring from the rhs crank seal area ? Ps great video
Thanks, honestly its been so long I cant remember but the bike is still around, next time I have it open I will check for it.
@@UpAllNight91 I since found out the oring sits inside the primary gear so you probably didn’t miss anything 👍
@@glennfern6622 Ahh that's comforting to know lol. I dont like making mistakes lol.
Is that piston slap ?
No, this motor just kinda has a vibrating sound around idle and in the shop on the wooden floor the camera captures it.
Torque wrench for anything?
Yes. I use torque wrenches on 4 stroke cylinder heads and a few other nuts and bolts here and there. But on a 2 stroke I hardly ever need them.
@@UpAllNight91 why not on the cylinder or the head
@baileyblount on a 2 stroke Its not super critical. Cylinder bolts with a normal size wrench is kinda limited or make it hard to over tighten them. And cylinder heads on 2 strokes are usually sealed with rubber o rings, these are not overly torque sensitive and only need to be tight enough to seal. After years of doing this work you get a good feel for the tools and hardware. There is nothing wrong with torque wrenches and they surely are needed in some areas. Some people (my brother) prefer to use them on almost everything and there's nothing wrong with that.
Friend, is this rattling noise in the engine normal?
Hello. The sounds you hear on this bike is normal on these 2 strokes, yes.
@@UpAllNight91 I understand, I have a 150sx after running it in it made this rattling noise. thanks
Yes Sir
Sorry this is no about a video a just wanted to ask you question about transmission oil in yz 250
Everywhere its said that i should fill it with 750 ml of oil
But if i will be doing it with oil level bolt i only get in 450 ml
What is the right way
Hello. The oil check bolt is kinda in the wrong location. It was first spotting out in the early 2000's and I guess yamaha never corrected it. I used 750ml of oil in the YZ250 if its a bone dry motor after a rebuild. If its just a oil change then I put 700ml. Been doing it like that for years with no issues.
@@UpAllNight91 oh thanks
Somebody should take that bottle or red lock tight and make you drink it. Do you have any clue? What a pain in the acid is to get those bolts out. When you use the red lock type, it is made to be permanent. That is why they make blue, so stop using it man. All you're doing is making it harder to get the motorcycle part. And in some cases probably damn near impossible to take the motors apart without stripping the threads out. So knock it off.You're not supposed to use that shit and you damn well know it if you're any count as a mechanic.
I have about 30 years experience. I dont have a problem removing bolts with red threadlocker on them. The key is a dab will do. The only time I have ever seen red threadlocker cause an issue is when someone completely drenches the threads and bolt from one end to the other as if they dipped it in the stuff. But otherwise no issues. I have also seen what happens when a bolt comes loose while on the track. These are track bikes being put together to be as safe as possible. Blue is great for beginners but red is best if you know what your doing.
STOP buying lock tite, they provide money to organizations to CLOSE DOWN OHV trails.
Seriously, stop funding a company thats investing into destroying trails.
Buy another brand, stuck nuts, permatex, anything.
no
I will take some time to look into this. If its true I will surely switch brands. Thanks for the heads up
