What if I decide not to remove the forks but suck out the old oil.  Can I get away with this as long as pump the forks  to get all the old oil out and I also have 600 so I simpler setup in more forks!

I've never done this proceedure on a 600, but I remember others saying that you can leave the fork in the triple tree.  So yes... I think that is possible.

Glad, we could help!  I might add some pictures to show how to replace fork seals too.  All in due time!

I have a B6 and would highly recommend pulling the forks.  To get all the old oil out, you really need to hold them upside down and pump them.  This way, you won't have any old thick oil messing up your passages.  In the meantime, you can get other maintenance done like checking your brake calipers, greasing the axle, etc.

Is it the same for a b6 as for the b12? if so wont mind doing that to my front end, it now dive's a little due to double HH pads and SS brake lines.
but I do stop quicker now just need to stop the dive so much. :banana:

The B6 fork is a different animal.

The B6 forks are the old and simple damper rod, not a cartridge unit like the B12.  Working on these was like going back in time, my '82 Yamaha had these.  The upside is that they're easy to work on and fairly goof proof.   The hardest part I had with the spring swap was putting the fork caps back on (you're compressing a spring and trying to thread the cap on fine threads).

Its about a $100 for springs and fluid.  Do it as soon as you can, it really changes the bike.  It won't dive under hard braking and when you hit potholes, railroad tracks, etc. it won't get all bent out of shape.

The previous owner changed the fluid and seals in my forks right before i bought it.. which was less than a year ago.. but used the stock springs

Is it possible to switch over to some progressive springs without having to remove the forks and do the fluid too? It seems like one could just pull out the springs and swap them out.

Thanks

Adam, Ampster did just that when he put in his. See the FAQ for his write up.
