That's one rough bike to start with....  which will make the build more rewarding. 

I think you'll be happy in the end as '01 is a good year for the yz125....  I know I like mine an awful lot.

'01 is the last year they had a steel frame AND a 6-speed trans....  '02-'04 went to a 5 speed trans and '05 went to aluminum frame.

I also think you'll be happy having it stay a 125...    once you go up in displacement, it loses a lot of its charm.

Yamaha went to a 5 speeder from 02 onwards? Really? As if the Hondas weren't enough of a failure.

Only the '02, '03 and '04 yz125 were 5 speeds.  They still generally won the shootouts, though typically in spite of the 5 speed. 

'05 onwards went back to a 6 speed trans, and they have aluminum frames (which are not my preference).

So here comes the fun part, ordering parts! Woohoo! It is going to be a big bill, but I am doing this so that I can learn about motorcycle mechanics. However I really need your guys' help. I am trying to decide between a Hot Rods crank and a Wiseco crank. I had previously installed a Hot Rods crank professionally and it shredded to pieces after about 6 hours in my Honda, so I am very hesitant to go Hot Rods again. However I have heard many good things about Hot Rods, and that maybe I just had bad luck. What do you guys think?

Or do you guys think that I should order the tools necessary to build the seized crank that I already have?

Deinitely go a new crank but as for hot rods or wiseco, I've heard more bad things about wiseco. You're the second person on here that has had a hot rods seize in six hours on a honda. Was yours an 85?

Pretty sure my 2001 CR125 had a hot rods in it that held up well to my (extreme) abuse.

check out partzilla.com first and see how much an oem crank is, I assure you it is better than both.

Well, my parts came in, and it was like Christmas! Unfortunately I found that I have a few parts I still need to get, if anyone has YZ parts they would like to sell, let me know. Anyways, here are some pictures of the goodies.

Oh! Also, how do you know if you need a new head, and where could I get one repaired, or even modified?

Is there damage on your current head?  Typically it will only need replaced/reworked if there is pitting in it from detonation.  The pitting will create an initiation site for future detonation.
