crank seals

How diffucult is it to install new seals on these bikes? Ive done a ton of my own work but I have never actually done this repair before. Its an 88' 250R.
Thanks

not to bad!
one thing I recommend is getting a cylmer manual, it gives a few helpful tips for different things...
for example they recomend screwing a very small sheet metal screw part way into the seal and pulling out with pliers.. instead of prying out with screw driver and possible scratching the surfaces...

but my point is you can get some good tips from a clymers, along with the factory service manual

I have a Clymers manual that I haven't needed to use in forever. Perhaps its time to break it out.

Are the seals easy to mess up? Do they have to go in perfect or if they go in they are are pretty much good to go?
