...or maybe some pictures. It is pretty much reassembled in the reverse order of disassembly. If you didn't take photos or notes of the disassemble, you should look at some of the build logs posted on this site.

here are a couple of pics but i have gone more than that :)
after i've seen some metal dust in my oil i have taken it all apart and seen my rotor broken but the good thing is that i have labeled everything.
I have changed my crankshaft, flywheel rotor and some mechanic guy told me i should change my piston rings too (no matter what) although some other mechanic guy say they're in good condition.i know i can follow some user manual books for assembly but i was wondering if there's anyone else done this before and maybe videotaped or took some pics while doing cause i know for sure there will be a lot of problems i can't figure out with the book since this is my first bike and i have no experience.

Looks like you have a full teardown on your hands. For starters, you will need to establish every part you put in is within service limits. I think the folks on this site can help.

Normally, the crank and transmission is installed in the top half of the crank case. I would suggest you post detailed photos of that. The rod small ends need to be checked for size and the big end needs to be checked for radial play. Then the transmission shifting forks need to be checked for fit with the shift rings. Once they have been checked and set in the case, the lower part of the case will need to be sealed to the upper half.

Do you have a manual? If not send me a PM with your email address and I will send one to you. Also, go into the 450 DOHC engine section of this forum and start looking at what others have done.

This looks like a great learning exercise! I'm sure it seems daunting now but soon you'll have it back together and you'll know this motor better than the back of your hand. One of the hardest things to learn is not to be afraid to back up, disassemble things and recheck your work. It's far better than the alternative.

thank you for the manual but you forgot sending the 3rd part.
that would be great if you can send the 3rd part when you get a chance.
