Just rebuilt my '15 FC 350 and was similar to this. Had to take the engine completely out being the main difference. Slight chatter at first which I believe was due to the cam chain tensioner getting charged with oil.

As well as the timing gear I think it would be important to show how the hydrolic ratchet type timing chain tenchener works as its not something most people can figure out without being shown , its just 1 of those things.

Thanks for the video -- did you go back with a stock or aftermarket piston?

How did you pull the chain through? Did you unlock TDC and rotate engine?

How many hours would you say the bottom ends are good for in these bikes?

nice job. now come do my 2017 450 :)

What was the piston ring pattern ??

Hey what Piston did u replace it with

Is there a reason you replaced the cam chain, or was it just because you were that far into the motor? Also did you replace the spark plug? Great video by the way. Going to attempt this job this next week.

thankyou brother

How did you remove the cylinder head ? Can’t get it past the frame?

Finally found a decent video on this bike but you skip the only step I'm unsure of.How did you go about take the cam gear off🤷‍♂️ ? Do ya just put it at top dead centre and undo it? What should I be careful of If anything?

Do u still have it

In the end was it the rings breaking in ?

Im looking at a 2017 KTM 250sxf factory edition. The bike has 77hrs and the top end was done at 50hrs. The owner is a serious moto cross guy and was using the bike for indoor tracks. Im hoping someone can tell me if this might be a good buy or avoid since the bike has been used I am assuming pretty hard.

Normally they are rid hard but are taken care of very well since he raced.

How did you do the cam chain? Did it have a split link in it?

I used a cam chain tool to press out a pin, then pressed the new chain together with a normal link. Make sure to round the edges out on the pin so that it doesn't want to work its way out.

I've had a few KTM's and they all seem to make the clutch noise you're describing. My friend put a Hinson clutch in his Husky and he said it eliminated the noise. Like you said, it's supposed to be a normal KTM/Husky thing

I’ve got a 2017.5 250sxf fe literally the day it hit 100hrs it started to make a noise when I pull in the clutch it sounds like straight rod knock haven’t pulled it apart yet called my local dealer that I’ve been going to for the last ten years they told me never heard of that before someone please lmk what this might be. Rebuilding the bike this spring 🤙🤙🤙

Lol. Pressed the cam chain apart. Don’t ever hack a motor like this kid. Skip to another video.

Please don't get me wrong. But this video is so not useful. A lot of tricky things people encounter on their first top end rebuild are left out. Like some useful tips to get the exhaust out. Or how to move the top end off. All those things are kinds missing. But still thank you for the video.

For real 4stroke bro???? I wil tel you wats real motorcross 2STROKES FOR LIVE !!!!!!!!!
