On second thought, I might ask my friend to quote me on this work. Doubt I would get this done in one day without needing to take everything apart again the next day. .
this fall I'm going to be rebuilding the bottom end on my 18 yz250f, I've seen comments about y'all having a vid of one in the works, please drop it asap! i could really use the guide
I've got a 2006 I'm doing now. How close is this video to a 300 xcw 2006? Idk what all has changed since then. This bike here looks to be atkeast a 2015 or up maybe?
I know this is an older video, but any chance this is similar to the counterbalanced bike? I'm chasing a lean condition that onl happens when the bike is SUPER hot. like 240deg hard enduro. It lean bogs and stalls. REbuilt reeds, carb, top end, exh, and still persists making me think it may be a main bearing seal?
@CHRISTIAAN NICOLAS HENDRIKSE Yes, crank seals. When they go bad they will leak air into the crank/combustion process causing a lean mixture, obviously more noticeable idle and is more pronounce when hot. Its good to also measure your oil perfectly every time you fill and drain to see if its losing oil through the crank seal as well, as this is a good indicator for the same condition. Once I replaced the seals(sometimes needs bearings/crank rebuild), the problem went away.
Top end, yes, if you don't know the last time it's been done. Bottom end? Most likely not, they can go a long time before being rebuilt unless there's something in there that shouldn't be there.
Sorry, but unfortunately we only have top end parts available for your bike. There are various bottom end components available on our OEM parts finder that you can check out here: www.rockymountainatvmc.com/oem-parts/KTM
i need help i m gonna rebuild the motor of a ktm i bought for very cheap but i m not sure if it s a 300 or a 250 cause the boy told me was a 300 but 300 sx in those yrs wasn t a thing so i m thinking is a 250 with 300 kit but how do i ensure this
I know you get a lot of these but I honestly think you should do this on as many bikes as you can and sell the videos I have a 16 ktm 250sxf and would be willing to pay good money for a detailed full engine rebuild , you could make money on the videos and the parts
The manual says CHANGE the connecting rod and crank pin. NO average person does this. My 2005 has been raced for years on the same crank and crank pin. KTM needs to rewrite their manual. Yeah...maybe... if you are a factory race team mechanic with unlimited access to replacement engine parts....
Bottom end rebuild after 40 hours? You guys are crazy.
hahaahahh 40 hrs ? how about 500 !
@@ExploringCabinsandMines how about 600-700 like me i don't ride hard though single track more lugging around up hills

Nice!!! In Spain we say... Bravo!!
Great to see 2 stroke rebuilding video
I can already sense that I'm going to end up with a lot of left over parts when I put it back together...

Do you have to remove the engine to replace the shifting forks?

Thanks for the vid!

Brilliant
How do you adjust the timing? The manual incorrectly displays this part as it shows the stator mounted to the motor, NOT the cover
it is worth to complete rebuild the engine (bottom and top end) on my ktm 300 exc year 2010?
Top end, yes, if you don't know the last time it's been done. Bottom end? Most likely not, they can go a long time before being rebuilt unless there's something in there that shouldn't be there.
Rocky Moutain atv can u please tell me where to purchase parts for a 96 ktm 300 exc. bottom rebuild kit

1st ......! If u Rebuild it I will ride!!
How does this bike look so rough in 40 hours!

You'll have to open up the top end and check the piston to see what size piston is actually in the bike.
Can you do a video for a bottom end of a yz250f!!!!!!!
We'll get it on our list for the future. Thanks for watching! - Chance
same principle
80 hours yeah right lol most people don’t even need to until about 500 hours unless you’re really bad at keeping your air filter clean
Which is the model year? Thanks!
This bike is a 2015.

Combustion engine. Electric motor
Haha you are a stickler. I think they're pretty interchangeable, not too many people know that.
Thanks for watching!
