Reply #16 - 05/04/12 at 13:34:03 There are 4 4mm holes in the bottom of what is essentially an open tube. The oil can flow both ways through the holes, so it is the same for compression and rebound. The difference is that the spring hinders compression and assists rebound.

Yep... seals, dust seals, seal clips, and bushings. None of this stuff is expensive, and the only difficulty is getting the damper bolts out.

Service manual says: Frame # up to 103407-441 ml,103408 and after-447 ml. With the fork vertical, compressed, and the spring out the level should be 75.0 mm from the top of the fork.
Stock oil is 10 wt. Any bike shop will carry it.

Thanks for the info. I was just hoping that there was a way to check without having to remove the forks.

Cheater method with forks removed... Drain over night hanging upside down. Place on floor, stand upright, compress upper tubes into lower. Fill with oil of choice (I used Type F ATF) to top of upper tubes. Extend forks, bolt back into place.

Almost as good as a decent (read springer) front end. Almost no brake dive.

Note: Ford Type F automatic transmission fluid CAN eat the inner seals. Dexron/Mercon Type 3 will not. Both are heavier weight than the stock fork oil and a whole lot less expensive. Save the fancy stuff for other toys where fork tunability is more critical.

People who have no experience with such things have nothing to go by BUt the manual. Experience pays dividends, cutting costs & doing less labor to accomplish the same task are great dividends. If I was doing this job, right here is where Id lay the manual down & go with what some old dude who has messed with things says.

My grandfather used to say "you have to learn the rules before you can break 'em.)
Kind of applies here too.
