One of the best videos I've seen for a noob to figure this out. Nothing skipped or brushed up on. Great camera angles. Exactly what I was looking for!

@ssse3123 Год назад

Thanks!

Thank you for sharing your expertise! Great video

Great idea using a vise to prepare the chain tensioner.

It is better to instal piston from the top of cylender, great video

@ssse3123 Год назад

Top and bottom both will work. Top side allows piston to go in straight easier but bottom side has a nice tapered edge for the compressor.

@AEXRT65 Год назад

Great video 👍👍 My opinion This is the most beautiful and strong engine ever made it is like a diamond master piece..

@tanishpatel9508 Год назад

wonderful job but why use a oem piston when you could use a weisco

@JanASS1991 4 месяца назад

Great work and nice music taste! What is the method of instaling circlip/pin lock with socket and pillers? You push circlip with socket and squeeze it with pillers? This is one of the hardest part of top end rebuild as for myself who does it once every two years.

@ssse3123 4 месяца назад

Without proper tool the circlip part is always the hardest part. I finally gave up and ordered the KTM tool. See it here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o1UohmGV5ys.html

@JanASS1991 4 месяца назад

Thanks for reply. Installing with KTM tool looks so effortless. I was thinking about buying it but went the old, cheap but scary way. I'm right now in the process of rebuilding engine of my FC 250 for a second time. First time I was STRUGGLING with circlip installation and was really stressing about it. This time I used straight tool pick and it went really easy, I actually suprised myself. @@ssse3123

Hey, great vid. Have mine assembled minus the valve cover. Timing marks are still where they should be. When I rotate the engine by hand, the timing chain gets a loose spot. Should this go away when there’s oil pressure ? Wondering if it is normal. Oem tensioner. Thanks

@ssse3123 10 месяцев назад

I have not noticed a loose spot myself. Double check everything before you start it up. Chain will rattle first 5 seconds when oil pressure builds up.

hello, did you do something (honing etc..) to cylinder? or just put piston nr2 ? thanks for answer

@ssse3123 7 месяцев назад

Nothing was done with cylinder.

@user-fl3hg9qr8i 4 месяца назад

Is it possible to have the crank 360° out, even if crank got locked while assembling and cams pointed right? I have a no start situation, have fuel/spark/compression. I wonder if it only sparks every 720° or is it wasted spark (every 360°)? I'm a little stuck right here

@ssse3123 4 месяца назад

Should spark every 360 deg because ignition is controlled by crankshaft.

@ktm4ever1 Год назад

Hi! Just asking what your manual says? 180 or 120 degree? I have 2015 sxf 350 and my manual says 120 degree and I looking for some informations about the piston ring gap orientations on the oem pistons

@ssse3123 Год назад

If your piston has 3 rings then it's 120. For 2 rings it's 180.

@ktm4ever1 Год назад

@@ssse3123 1 compression ring, 1 oil scraper ring and 1 oil scraper spring

@dougwisdom1239 6 месяцев назад

Do you have any idea as the cam degree, since mine doesn't habe the punch marks on the cam gears?

@ssse3123 6 месяцев назад

What year bike? Some older ones have markings on the cam bridge at the opposite side of chain. These match with flat parts of camshafts.

@marcavella Год назад

Should one replace the timing chain on the first piston change?

@ssse3123 Год назад

Check if all chain links move freely and are not sticking. Hold the chain up and see if all links align straight. If not then replace chain.

Thanks for the tip 👍

book calls for lactate 5910 between the engine case and cylinder but I have seen multiple videos of people putting on no sealant in that spot. what do you think I should do?

@ssse3123 7 месяцев назад

You can use it but don't put too much that it gets into the engine. You don't want this stuff getting in to oil passages.

@damoncustodio6577 7 месяцев назад

@@ssse3123 do you think it would be fine without it? After seeing a few videos of just sealing the top cover I’m thinking of just sealing that but also don’t want to pull it apart again
