I recently replaced the fork oil in all 3 of my street bikes and 1 of my dirt bikes. I used a cargo strap to compress the springs to get the top cap off and although it worked I figured I would look for something a little more professional the next time I needed to tear my forks apart. I recently developed a bit of a leak in one of my fork seals so I ordered a new seal and started looking around for a spring compressor. I found several online that ranged from about 50 to about 250 bucks. I found some people who made their own and I decided I would make my own but I made mine a little different than any of the others, or actually a cross between a couple plus my own touch that I didn't see on any of the others.

I've been wanting one of those heavy duty long clamp devices which is basically what that 250 dollar compressor used. I figured I could use it in my spring compressor and use it as a regular clamp. So I picked up the clamp for about 30 bucks and about 10 bucks worth of other parts and this is what I ended up with:

I used a 3" pipe connector but a 2.5" probably would have been better. All I could find at Home Depot was a 2" and a 3" and the 2" would have been too small so I went with the 3". I guess the 3" does give you a little more room to slip the fork into. Either way it worked like a champ. Also, I can probably cut of a bunch of that excess threaded rod and maybe weld a T handle onto the one side.

I picked up a 12" long 1/2" threaded rod and some half inch nuts. Just cut that rod in half and grind one end on each half down a little to somewhat of a point. Drill a hole through the two pipes and thread the holes with a tap. Or in my case I just ground a few notches into the pointed end of one of the rod ends so it became "self tapping" and then just put them together as pictured. I put the nuts on for a little more reinforcing. I have thought of ways that it could be reinforced even better but it didn't really need more reinforcing. I am pretty happy with how well it worked.

Actually that fork is out of one of my ZX6Rs, but it's not much different than the one in my YZ250, just a little smaller.
