Replacement forks for '87 C-10
« on: August 07, 2017, 11:45:53 pm »
Will any C-10 fork work with any other C-10?  I'm looking at a set of '98 forks, but don't see the air valve.  Was the air valve done away with after a certain point?

Yes, I believe  '94 and up do not have air adjustment.

The brake calipers changed on the later models.
I think I recall that you cannot install 98 calipers on a 87 Connie.

So, I assume the forks from a 98 would not work with 87 calipers.

You are correct Ted...to use '94 and newer fork tubes...which will slide into the '86-'93 triple clamps...you would also need '94 and newer brake calipers, rotors, and wheel...it's worth the changeover, in my opinion...but, to make it cost effective, I would look for a complete front end...and just slide the fork tubes into the bike's triples...of course, there is the 17" front wheel mod too...

Thanks for the replies, guys.  Just want to be clear that the front end is interchangeable on the '87-'93 years, then changes with '94.  So any bike from the early years could donate forks and my calipers and wheel would be fine.  Right?

I like the idea of putting a post-94 front end on, but I don't want to go too crazy on a bike that cost me 700 bucks.  Just want to get some front suspension since the schrader valve is broken.

And I call the bike Axis--Japanese bike, German front tire, Italian rear tire.

Why not just buy a Schrader valve?
Available at ACE Hardware, probably Home Depot, or a water well shop.

As noted above, you can buy a package of schrader valve inserts for like $3 for half a dozen, at any auto parts store.. you will need the "multi tool" also, to remove the valve insert..... $1.50 at tops.

The parts on all front ends, are.dictated by the axle and wheel bearing sizes, which changed in '94 , everything prior to that, had air assist forks... after that, '94 up, did not have air assisted forks, and the wheel and bearings, n axle, n brakes changed...

The big key is the axle and wheel bearing size...

The simplest route to a solution, buy a new valve!  Many thanks, once again, for helping find the simplest solution.

The left fork nut  is impervious to movement, even with an air powered ratchet, so to refill after draining the fork, I put the corret amount of oil into the air hole in the left fork.  The right fork nut is no problem, but the schrader is broken.  I was thinking I was best just putting on a set of forks to solve both problems, but since I can work around the frozen left nut, simply replacing the schrader is the simplest solution.

Again, thanks for the help.  This is a great group.

If you are dumping and replacing the oil, both fork top nets must be removed, and replaced after putting in the correct oil to correct levels...
Only one cap nut has a schrader valve insert, the other is simply a threaded stub on the cap, for. Plastic cover to attach to... the air, when filling, should not excede 7 psi, this is criticle... also note that there is a crossover tube, between the 2 forks, that equalizes the air pressure between them, but air pressure only... not oil.
Also, before you damage the top nut thing, squirt some penetrating oil, like PB Blaster in the top of the tube, and let it soak into the threaded cap...
Also, completely remove the upper tripple tree clamping bolts at the top of the tube, and take a flat bladed screwdriver, and drive it in each "slot" on both sides of the trippe tree, and leave them in place while attempting to loosen those top cap plugs... there can be no "pinch pressure" or the caps will never fome out... and you will ruin them and round them off... happens all the time.. so what I'm saying should help...

HxnutMike, you shoulda told us the fork cap was frozen.   :41:

We woulda tried to help you figure that out..

Bukuz you didn't ask,, I now have to agree with MOB...
                                                                              Owww, the shame!  :sign0137:

What MOB told you is right.
Loosening/removing the caps is often missed and the caps don't come out.

ie: Before trying to get the cap off.
     Loosen the Upper triple tree clamp bolts and lubricate the cap threads.
     Bang on it little too. {it might loosen the corrosion and it will help ya feel better}  :great:

Ride safe, Ted

Pre 94 fork clamps, on every one I serviced, needed to have the bolts totally out, and a screwdriver blade pounded in both slots to spring them open... to insure they aren't rusted in place...  they are surprisingly tight, and everything helps... pulling the tubes out of both trees, even with bolts removed from all of them, requires that "wedgie the slot thing..."
Also requires completely loosening the clamps that hold the air crossover, and carefully prying those collars free... lubes help there also....
