hey m.b. co you wouldn't happen to know were I can get myself a pickup coil
Is the resistance out of tolerance, or do you have an open connection (no ohms)? If the latter, you might be able to figure out where the wire break is and re-solder it.

I have yet to come across a vendor online selling them. Doesn't mean they are not out there, just that I haven't found it.

If you have a motorcycle salvage yard near you that may be the best bet.
 
Re: 82' KZ440 Cafe' Brat Build: I hate you

The reason I gave you the advice to (possibly) fix the one you already have is that this item was only available for a couple years (the latter liquid-cooled twins use a different sensor) and NOS pickup coils are expensive (if you can find them).

Adjusted the valves and no improvement.

Compression did raise slightly, but nothing to cause it to run any better.

I don't know what else I can adjust, replace or diagnose. Before I even start to tear down the engine I may drop if off at a shop to have it fully diagnosed to confirm. I hate chasing issues.

what are the sizes of all your jets?
 
Re: 82' KZ440 Cafe' Brat Build: I hate you

93 secondary- Stock = 88
68 main- Stock = 65

I may raise them up slightly again but I've changed jets around and saw no improvement. Didn't think it was directly related to the carbs/jets
 
Re: 82' KZ440 Cafe' Brat Build: I hate you

Electronics tray/box is aluminum. I think it's 14g or 16g. It's pretty thin, I didn't need anything thicker as it needed to bent the shape of the frame.

really!!!!!?

My 440 with free'err flowing exhaust and stock airbox begged me for

40 pilot about 2 1/4 turns open
72 Primary Main
98 Secondary Main
1 shim on the needle.

I think you might have burned your rings and valves with those jets for PODS and Open exhaust.

Hmmm... Stock airbox and you went up that far?

You have CV32 carbs too right? How did you shim the needle? Mine didn't have any shims on it.....just a needle.

Is the pilot jet under the air screw? Mine only has 2 jet's in the bowl, the main and secondary.
 
Re: 82' KZ440 Cafe' Brat Build: I hate you

From my understanding that is the secondary main. (from the KZ440 manual). Jet I removed from there is a 88 and replaced with a 93.

In both my Kaw factory parts book and my Clymers the pilot jet (92064) is under the plastic plug (with small "O" ring) and was either a #35 (limited countries) or #38. There are 2 (92063) main jets per carb; one (the main, pri) under the main emulsion tube was a #70 (#75 for racing), the other (main, 2nd) under the emulsion tube the needle valve from the diaphragm goes in) could be all sorts of values from #82 to #92 depending on country and application.
 
Re: 82' KZ440 Cafe' Brat Build: I hate you

To save me scrolling through, have are you using the mechanical timing advancer or, half electric/half mechanical or full electrics?

what are the benifits? the guy who did my motor said it could be a good idea to swap to half electric/mechanical
 
Re: 82' KZ440 Cafe' Brat Build: I hate you

The fully (factory) mechanical was used with the points ignition (anything pre-'80 in the USA). Points kits are easy to obtain and the advancer mechanism works well if lubricated. The "half electric" advancer combined the previous mechanical cam/weighted advancer with a Hall-effect pickup and a TCI ignition module (no points). Only used for a couple years and parts are now becoming scarce (the liquid-cooled twin uses a completely different ignition system). "Full electric" might be an aftermarket Boyer unit? Not ever seen one so I can't comment. Another option (for points) is to use a NOS CDI unit from back in the day. Extends the points' life way longer as only the signal current runs through them (ignition current runs through the CDI unit).

so whats the benifits of having a half electric?
