KZ650 converted to electronic fault

I will still check my 650 engines and get back to you.

One difference with the bigger engines is that yours has only one spring.  My Z1 advancers have two.

As I understand it here are the part numbers for the advance unit on the 650s

21148-011 (points)
     
KZ650-B1 (1977)
KZ650-B2 (1978)
KZ650-B2A (1978)
KZ650-B3 (1979)
KZ650-B4 (1980)
KZ650-C1 (1977)
KZ650-C2 (1978)
KZ650-C3 (1979)
KZ650-C4 (1980)
KZ650-D1 (SR) (1978)
KZ650-D1A (SR) (1978)
KZ650-D2 (SR) (1979)
KZ650-E1 (LTD) (1980)
KZ650-F1 (1980)

21148-1022 (electronic)
       
KZ650-H1 (CSR) (1981)
KZ650-H2 (CSR) (1982)
KZ650-H3 (CSR) (1983)
KZ650-F2 (1981)
KZ650-F3 (1982)
KZ650-F4 (1983)

 

I was able to check one in my parts bins, but the other one is on an engine in a 650 stored up against a wall where it's difficult to access.  I took a photo of the one I found.  It has no 1016 code on it and it has two springs.  I think someone may have switched advance units on your bike at some point.  (Or is it for an OEM electronic ignition?). I can definitely say mine came from a 650 engine, but it may not have been original to the bike...I just don't know.  The engines are 77 and 78.

Edited to add that the manual I have for a 650 says the advance should be 10 deg BTDC at 1,600 and 35 deg BTDC at 3,200 rpm.  Neither of my engines are electronic ignition.

That part number matches up with the one I purchased and fitted (1016) see attached image.
Any thoughts about the resister in the plug cap ?, mine are NGK 5ohm resister type ? should I be using the non resister type ?
Happy Christmas when it gets here.

According to Partzilla the one you bought (1016) is for a KZ550.  GD4Now has pointed out that the correct number for a KZ650 is 1022.  I checked Partzilla and he is correct.

Any idea what the difference is ?, as mentioned others on the forum have fitted the 1016 on their KZ650's ?

I don't know what the difference is.  You might try contacting someone who has used the 1016 advancer to see how their bike runs.

Just had a quick look on CMNSL - the pick-ups look to be generic across 650/750 models but the 1022 advancer appears to be 650 specific ?? Have you tried using a strobe to see what is happening when you pick up the revs ?

I may of taken this topic off its rails with the part number info, that was not my intention. The advancer you installed may work fine with your machine, I certainly do not know that it will not. I am still interested in what igniter you are using? Is it for a 550 650 1000 or some other bike/model?

From some of the manuals I have access to the 650 stock points systems indicate the following 
from 10 degrees BTDC @ 1600 rmps to 35 degrees BTDC @ 3200 rpm

650 electronic system indicate the following 
10 degrees before BTDC @ 1000 rpms to 35 degrees BTDC @ 3200 rpm

the 550 manual indicates 
10 degrees before BTDC @ 1050 rpm to 35 degrees BTDC @ 3200 rpm

Hi Wookie, I have found a 1022 in the UK but guy wants £100 which is a lot if it don't cure the problem. Bikes driving me crazy at the moment I have gone from a slight misfire at tick-over when blipping the throttle to a bike which won't rev properly lol. I have a strobe gun but never 100% sure how your supposed to see the marks through the tiny hole  etc.
As it stands today, she started OK but cylinder 1 was cold ?, checked float bowl which had fuel, checked for spark which was good....several minutes later the cylinder starts up but she still doesn't run well at 0-1/4 throttle once past all seems good but cannot road test as weather is poor.
New 3 ohm coils coming tomorrow/Saturday which the guy I purchased the pickup & ignitior said could be the problem? he says he's had problems in the past using 4 ohm coils with electronic ignition modules.
I can temporary wire these coils in and weather permitting test ASAP

Sorry I tried posting the link to eBay but it failed, the IC was from a KZ650 D picture attached.
I would presume this would be perfect for my KZ650 B ?
