I'm using the complete front end from a '94 Yamaha YZF750 Exup.
I rebuilt the front forks with new seals and good quality 10W fork oil. The springs are Ohlins.
As anyone who've replaced seals on these suspensions knows, it's a b*tch to get the spring spacer and fork cap back on without someone assisting you.
I was really pissed about not being able to do this on my own (again), so I scratched my head, and about two beers later, I designed this in my head and built it using some steel threaded rod and scrap metal bits.
It's ugly as hell but it works, and that's all that matters to get the job done.
The bottom end attaches to one of the brake caliper mounting holes, and the top "grappling hooks" fit in the metal spacer (which has one hole on each side for this purpose).
With one hand holding the spacer/hooks (with a heavy leather glove on, just in case), and the other with a 13mm spanner turning the nuts (which have been welded on to the steel rod), thus pushing the rod and hook/spacer down.
When it reaches the fully compressed position, you can simply pull up the fork dampening rod and attach the fork cap back on. Presto.
Just as a sidenote for all the lads on the FZX Club:
Notice "The BIG Hammer", on the second pic. Always have the big hammer near by, for when things don't go as you liked to. That, and lots of beer...
