Interesting morning w/ the SP1000
« on: February 09, 2019, 09:02:52 AM »
So this morning I figured I'd tackle the forks, you know take them off really clean the internals and rebuild, replace or reassemble as needed. Guess its going to be more of a replacment at this point

I roll the rear of the SP on the life and into the wheel chock strap the rear of rthe bike so it cannot rock L/R and then put a softie and scissors jack under the oil pan. I talke some pressure off the from wheel to remove the axle, calipers and fender so far so good. I get the from calipers and axle removed and the forks drop a bit. So I wind the jack up and get the front wheel out. Then the fun begins....all of a sudden the fork lowers continue to slide down and off the fork leg. The only thing holding them on is the fork gaiters. I quickly slide each lower off and 1/2 the spring portion of the damper is still in the lower and the damper chamber is still in the for leg.

Thank goodness I didn't put off the fork maintenance as they seemed to be working at least marginally and could have easily backburned until after it was on the road. Could have been catastrophic. I guess its not when in doubt check it out with this older stuff. Its no doubt check it out!

Looks like the rod came completely out of dampener or the bottom came off them.  Are they still screwed on to the bottom rod w/locknut?

Yes the tops stayed with the fork caps and the spring section stayed with the fork lower. Completely separated. For the record there was no hitting or hammering involved. I fully intended on sliding the complete fork out of the triples then disassembling. Good thing for those structural gaiters that were held in place with zip ties.


New dampers are on order and next week I'll get it back together. Now I have an opportunity to take the lowers and discs to work to bead blast them and do a repaint. Today has given me a few lemons so I'm making limonchello :thumb:

Wow, thats scary! Good thing you were pro active in looking at that front end! What brand of dampers are you putting in there?

Does it look like the bottom of dampener rusted out? I've never seen one come apart like that, have taken apart some rusted up ones.

There wasn't a drop of ATF in either. The o-rings on the dampers were brittle, cracked, cut and/or marred but corrosion was minimal and all the metal seems in good shape.

Someone did put gear oil and molly additive in there.  "A" for effort
