The best trick you can use is a manual and the right tools. :-D

you will def. need at least a diagram to show you which way the gears go on the shaft as well as where the shims are,as for tools if you can take it apart ok then it should go back together ok without the need for special tools etc.

I think you need to take it to the shop or a mechanic that has the special tools and the correct shop manual that will be needed.

I would buy them. My dad always told me that anything worth doing is worth doing right and if you do it right the first time you don't have to do it again. You are going to need a flywheel puller, a puller for separating the cases, a clutch hub holding tool, a flywheel holding tool, a tool to wedge the crank and you are going to have to build a wood box to support the engine on while you do the work. A hydraulic press is a must have. You are going to be playing with some very expensive parts, any one of which could cost as much as the tools you need if you screw it up trying to do it the wrong way. For example a clutch basket could cost as much as $300.00 if you break it trying to get buy with out the $30.00 clutch holding tool or the $400.00 flywheel if you bend it trying to pull it with a claw style puller rather then the $15.00 dollar puller thats made for it. You know whats really cool is when the claw puller pops off of the flywheel and breaks a big piece out of your $500.00 cases. You are also going to need all of the torque specs, those can be found in the manual. Nothing will ruin your day faster then your flywheel coming loose and tearing up the end of your $500.00 crank. That is $500.00 + $400.00 because it also screws up your flywheel. You can't forget the famous over tightening of the clutch spring retaining bolt that breaks the post off of the $100.00 clutch hub. Fun Fun Fun, You will be singing the happy happy joy joy song for sure http://www.youtube.com/watch?v=ABWyXKT5qt4

BDI said it all. The days of fixing a bike with a screwdriver and a Crescent wrench ended about 1923.

give it a go its not as bad as it looks
when you get to splitting the centre cases
just make shure the gear box stays in one side of the cases
and fall out on the floor

just in the process of putting my 87 KX 250 back together, it needs patience, a manual, some mechanical dexterity, a good friend who is mechanically good to make you pause before you do a mad thing. The difficult tasks just require you to think about things a little
I am doing it so I know what to do in the future.
I made all the tools for pulling apart and pulling together using steel bars, 2 inch steel tube and threaded rod. Getting the crank in, requires a freezer and a partner who does not mind you using the oven for half an hour.
I can email you the pics of the pulling tools I made. I would buy the clymer manual before you start. It will be the best $30 you spend.
Once it is all done, I will setup a website. Look up Rocky Mountain ATV on you tube, it shows you the basics.
The other option is to pay the local dealer to do it but arrange so you can assist and observe.
Anyway, that is my view, good luck.

I and I'm sure we, would like to see the tool pictures, post 'em up please.

Here are a couple of pictures.
The Unistrut (the straight bar) was given to me, I purchased the rods and nuts for a few dollars at a local store.
The threaded rod needs to be M6 (2 is enough) and a M8 threaded rod to push the crank out of the case.
I will type it up in the next few days as a PDF.
Hope this helps

two pictures,
an engineering diagram (really bored at work today, so got busy on Visio!) and a picture of me using the same setup to press the cases together.
It literally took 30 seconds to press them back, completely parallel and no force.
The kit costs a few dollars or can be scrounged of a pal who works at a building site or engineering works.
