Special tools

My friend had a Harris Magnum2 with a Z1000 engine which we spent endless hours tuning. My favorite tool was a simple strip is wood bolted to the wall behind the bench. It had holes and hooks for all sorts...just a few inches above the bench. The real surprise came when we started compressing valve springs using a long lever across the bench. The valves needed something underneath (a small piece of plywood off cut) but a simple 'fork' sticking out from the side of the lever pushed down the springs enough to remove the collets on dozens of different heads. We made a couple of special tools to press with (an old socket spanner with a big slot ground out worked well). I even used this technique on my own putting the lever under my arm leaving both hands free.

Now back to my 650-750 conversion... trying to loosen the clutch basket retaining nut...MMMmmm better read the manual first!

I wish I could find the pic I saw on here for holding the rotor still on the end of the crank.
They had a BIG combonation wrench, one end on the foot peg bolt and the open end had one of its points in the divot on the rotor.
The wrench holds the rotor still while you loosen the bolt.
We did that on kzl6060's engine and it worked great!

Was it me?



NOTE: this picture shows the position for *tightening* the bolt on the rotor, since it is left-handed threads (on my bike at least). Flip the wrench over, and it works for loosening...

...oh yeah.... I'm the king of inappropriate use of tools...

I guess I forgot to update my progress. Here's what I ended up using. Worked great and barely left a mark on the rotor.

Yep, it was you. That was a great idea.

Anyone got an equally clever way to hold the clutch basket while I apply 150lbs of torque to the retaining nut?

One way is to weld a handle to an old metal clutch plate. Of course the problem with that is not everyone has a welder in their garage...

I've taken off several rotors off 650s with no holder tool for the rotor but darn if I remember how I held the rotor. If I was going to do it today, I would take an impact socket and use an electric 1/2" impact tool to tighten the rotor removal bolt into the crank and pop the rotor right off just holding the rotor by hand I would wager to bet.

Ron, before we got our new compressor I used an electric 1/2" drive impact and it pulled the rotor off about half the time, the other times I tightened the axle in the rotor with the impact then smacked it with a hammer, that took care of the other half

Don't you just love that chain vise! Indispensable.
Did anyone ever poke a length of rope down one of the spark plug holes to lock the motor? A foot or even half a foot would probably do, then use an impact wrench/gun.

here is my contribution to home made tools.
I'm pulling my motor out of my 91 kz1000p and needeed a special tool to remove the chain drive gear so I could take the chain off.
this is made out of 2- 14"x 5/8" anchor bolts for a concrete slab. home depot $1.70 each. came with nut and washer that I can use as a gussett or whatever. bent them at aprox a 45 degree angle so I could get a socket on the nut. weld the 2 toghthet and bingo. its "sturdy not purdy"
