hey guys
hadn't been on here much lately but its a new year and i'm think about my bike again.

i am going to buy a new set of coils. looking at some at z1 enterprise.not sure the ones i need. i think its the dyna dual output 3.0..my bike is a kz650b 1978.
if this is what i need will they work with my stock points..any help will be appreciated..mustache

Yes, the Dyna DC1-1 3.0 ohm coils are the ones you'll want. They should work fine with your points system, but you'll notice a bigger diff if/when you swap to either the Dyna-S electronic ignition, or the electronic ignition from an '81 KZ650-F1 or '81~'83 KZ650-H CSR.
The bummer is the Dyna 3.0 ohm coils show as being "temporarily out of stock" at Z1Ent.

i thank u for the feed back..they are out of stock at z1..are there any place else i can buy some or do they stay out of stock very long. if not i can wait...thanks again

i found a place on ebay that sells the dyna coils..it said for older bikes with points that dyna recomends 5.0 coils. can any one conferm this to be true or not true..thanks for any help

At this time of the year, suppliers typically have closed for a week or two, such as Dynatek. While z1enterprises.com may be out of the coils today, they likely will be getting some in the very near future. Try calling Jeff, the owner and finding out. I suspect they would arrive just as quickly from Z1Enterprises as the namesless eBay seller. Also, get the green 3.0 Ohm coils. They are the correct coils.

What Dyna actually says according to their web page

DYNA 4000 Pro Ignition

Must use DC9-1 or DC9-2. The DYNA 4000 ignition system is designed for racing only and is matched to the characteristics of the DC9-1 coil for optimum energy production.

Recommended - DC7-1, DC8-1, DC10-1, DC3-1, DC6-1. Use coil with 5.0 ohms primary resistance for street use, 3.0 ohms primary resistance for racing applications.

At the top of the page though, Dyna says

Before selecting a coil, check the coil primary resistance requirements as specified by the manufacturer of the ignition being used.

If you search this entire site I don't believe you will find recommendations for anything but three ohm coils for the KZ's.

Like everyone already said, you'll want the 3 ohm coils. They have the widest range of uses. They'll work with points, the stock electronic ignitions, and the Dyna S ignitions.

i would like to thank everyone for all the help.this has been a big help..thanks to you all..mustache
