TOPIC:

Does anyone have a 1000P speedometer they could measure? any year from 1982-2005.
I'm trying to figure out if the police meters are basically the same size as my 650-csr. Thanks.

#1). Top/face OD. just hook a tape measure on the speedo & measure across the face. easy.

#2). Speedometer cover OD. measure across the cover where it meets the speedo.

#3). Mounting stud center-to-center measurement.

#4) Main body height above midpoint clamping ring.

#5) Lower body height below the clamping ring

1) 3 5/8

2) 3 7/8

3) 2 7/8

4) 1 15/16 to the edge of the ring

5) 1" below the ring

Thanks. Here's what I got for my 650, using a tape measure & double checking w a digital caliper. the measurements are within about 1/32" or 0.5mm.

1981 KZ650-CSR.

1) 3 15/16 face/housing OD at the top ... (100 mm)

2) 4 7/16 speedo cover OD ... (112 mm)

3) 3 5/16 mounting stud c-to-c ... (84 mm)

4) 1 13/16 above the ring ... (46 mm)

5) 1" below the ring ... (25 mm)

I am not sure what your goal is, but I discovered that a speedometer from a 1979 KZ1000 ST was a direct replacement for my 85 MPH 1982 KZ 650 CSR speedometer. It features a range up to 160 MPH. Mine does read about 5% faster than the previous, but the odometer seems right on. Others may be able to chime in on this. Here is a link to the style of speedomoter that mine is. Like I said, this may not be at all what you are after. So for what it is worth....

Thanks. I remembered that you installed a 1000E speedometer, problem is good ones are hard to find, whereas the police speedos are more readily available & at reasonable prices. I'm simply looking for a higher mph. The police unit goes up to 120 mph which is more akin to the 650's actual top speed than 160.

I must have gotten lucky. I paid about $80. for the 160 MPH speedo, and then sold my 85 MPH for $40. You are correct about the top speed, however I did hit a maximum of 121 MPH as read on the GPS, which was about 132 on the speedometer. That was a scary experience. At about 110 the bike seemed to squirm a little, so I very gradually increased through that zone before getting back into WOT. I do not want to do that again. I could have soiled my pants very easily.

My FZ1 waltzes through that speed and beyond with rock stability. Tremendous difference in handling, but I still love the KZ for normal riding. After riding the KZ on the Pacific Coast Highway I can daydream about that trip most any time. Great memories.

Was the 121 before or after you installed the 750 stuff?

It was after. The 650 cylinders were so bad that it probably would have topped out at about 110 on the speedometer instead of the 132.

Just so others will know --- the previous owner of my 650 must have let the engine sit out in the rain without spark plugs or something. There was serious corrosion and pitting of the cylinder walls. But in spite of that I still put almost 20,000 miles on the bike. Compression was getting worse, and on the highway I was using a quart of oil about every 500 miles. I thought the engine was finished.

But then I found parts from a good 750 on Ebay, so I bough the cylinders, pistons, rings. (Actually 738). On the later model KZs (about '81 and later) everything bolts right in. Earlier models didn't have enough clearance in the block, but it could be machined away if you really wanted to. The piston pins, rods, etc. all interchanged. The bike runs so much better.

Thanks. I would've been surprised (and skeptical, hee) if you got 652 ccs to go that fast.
What sprockets are you running & have you switched to a 530 chain? I'm assuming your bike came with a 630. I'm kinda wondering what your fuel economy is with the 750 stuff.

The sprockets are 14 and 33. The original 13 became very hook toothed, so I changed to a 14. The stock 33 rear sprocket is still hanging in there after 40,000 miles. Still running the 630 chain. I plan on switching to 530 whenever the chain wears out, but I can't seem to wear it out. Been using white lithium grease on the chain.

I used to get good mileage with the 650, but as time passed it got worse. For example, I would occasionally get mid 50s on a slow highway run, but that dropped to more like low 40s after the 650 got tired. Now with the 750 I actually have some compression for a change. Rode to Austin last Fall. Got about 56 MPG on 3 successive tanks of gas, running 70 to 75 MPH. I thought the low fuel light had failed, but it finally came on at about 105 to 110 miles.
