You'll need special tools costing more than $60.

It's not a complex job for someone mechanically inclined, that knows how to use hand tools and can follow directions.

But there is a complex set of procedures that must be followed to the letter.

Every manufacturer has it's own idiosyncrasies for rebuilding their inverted forks.

I've been repairing bikes forever and would never attempt that job without a shop manual.

With your qualifications, I'd say it's do-able.

Call some shops and ask what they would charge you.

Then determine what you'll be saving by doing the job yourself.

Purchase a shop manual - approx $35 (you should already own one!)

Fork Seal Drivers

Fork Oil Level Gauge

Fork Compression Valve Removal Tool

Dampening Rod Bleed Tool

You definately need the fork seal driver.

The other stuff cuts the repair time in half and can be rigged from ordinary tools.

If ya need help - just ask.

Another thing to consider - the sterring stem could be bent.

With the front end off the ground -

Remove the F wheel.

Loosen the pinch bolts clamping one of the tubes to the sterring stem.

You should be able to spin the tube 360 degrees without any binding.

Tighten it back up and repeate on the other tube.

Any binding and the steering stem needs to be replaced.

A special tool is needed to install the lower bearing on the steering stem (not really needed, but it makes the job easier).

I would contact a local Yamaha dealership you can find the phone number in the phone book you can buy a book with photos step by step like clinton repair type manuals or ask the service dept for advice.
