The 05-12 oem manual says be sure to turn the crankshaft counter clockwise to prevent the one way decompressor system from functioning. I see that he rotated it clockwise.
Hey thank you for this enriching video, my question is about the camshaft, why is there any decompression valvle, as per my understanding all the 400 CC motors are equipped with this cam that help engine start and maintain the runing in low rpm
What do I do if the cylinder where the piston is that will not come off I remove all of the bolts, and for some reason thought this would slide right off, but it will not at all???
Hey, after a complete rebuild, following your instructions word for word. I went to start it up, and an extremely loud knocking noise came about and it wouldn't start. I believe my timing was off and my chain was stuck somehow on the teeth deep down in there.
If you have an 05-12 year bike, the oem manual says when you set your Top Dead Center on your timing be sure to rotate the crankshaft counterclockwise to prevent the one way decompressor system from engaging. I noticed he turned it clockwise.
What rebuild kit did you use for this build? I saw the review you guys did for the QA kit and you said you used it on a build video I was wondering if it was this one

Entirely depends on the motor, engine wear, and how well the owner takes care of the machine...or abuses it. The bottom end of a motor typically has longer service intervals compared to the top end. Theres a lot of factors there.
15 foot pounds then add 33 pound that consider 48 foot pound? Manual it said 33 foot pound that it. I wasn’t sure you mean 15foot pound then add 18 foot pound equal as 33 foot pound of torque?

Time for a bottom end video! I have a 400ex that you could use to demonstrate lol
A lower end rebuild would be a good video addition for the 400ex!
This channel has made me self made thanks!!!

It would be helpful if you would show the way to do some of the stuff with and without a special tool.
Maysure

Thanks this video is great
How do you inspect the cam journals and rocker arms? I looked in service manual and don’t see how to inspect or specs.
Im doing the same rebuild but I notice that on the intake side of the head thers a threated hole right next to the carb intake what is the for
does this apply to the xr400r engine?
What do I do if the cylinder where the piston is that will not come off I remove all of the bolts, and for some reason thought this would slide right off, but it will not at all???

Did you figure out what caused it ?
If you have an 05-12 year bike, the oem manual says when you set your Top Dead Center on your timing be sure to rotate the crankshaft counterclockwise to prevent the one way decompressor system from engaging. I noticed he turned it clockwise.
The top end kit did not come with a o-ring for under the cylinder so dose that mean I don't need it or should I put one in? And what's it for anyway?
Did you ever figure it out ? I’ve got the same question
@@1johnathan011 yes I changed mine
What do you do if the motor locked up and you can’t spin it to find TDC
Shout out to the car alarm at 11:40
i forgot the orange o ring on bottom of cylinder been running it like that for a year now and no issues whats the purpose
It is to help seal the cylinder completely.
What was that plunger and spring by the valve springs I didn't have one
Decompression for stock cams. Hotcams doesn’t use it and some remove then.
What rebuild kit did you use for this build? I saw the review you guys did for the QA kit and you said you used it on a build video I was wondering if it was this one
I’m just confused on why there’s a plunger and spring when it’s clear that a stage 2 cam is present on the bike
I need the cam chain tool link

Great video but if the engine is worn doesn’t that mean the Crankshaft and piston rod be worn too so then the whole engine have to be replaced?

Anyone know what that cam chain tool is ?
