After melting a piston on my H1R at Willow and going through the "bird nest" of wiring which is a Krober, I think it is time to change it out and use something else.

What are other people using for ignition, preferably without a battery?

I found this one on line, which looks like it is made by the same company that makes the system I run on my TZ750, anyone have experience of this?

I think going with Jim's boxes and the Zeeltronics set-up would be a good idea. You can see Jim's products by going to his link on his Avatar and this is the Zeel stuff:

That's my plan as I upgrade....I have H2s. Not sure of compatibility with H1r.

I wouldn't think the resistor caps are a good deal, on those systems, mall they do is boost spark plug voltage output, and that would indicate weak coils are used. Ask them if the resistor caps are mandatory, and what spark level the system makes.

As far as the curve, are there more than one that can be dialed into the system, or only the one shown?? It appears the system has the right way of top RPM tioming control, retard, but, is it adjustable as well, separately??

Can't see in the pictures, are each pickup coil independently adjustable, or, batch fire??

Original H1R and H2R systems are Kokusan Denki, were good in the early days, but long on the tooth now. If you run across different spray painted colors on the boxes and stators, run all of those parts as a unit, not mix and match, as colors indicate the ignition curves/retards, and all differ. There were 6 that I remember, green, pink, red, white, blue, black (no paint), H1R were usually only black, but H1R-AS and LC had the added color curves.

In the day, the better systems were used on the TR750 Suzuki race engines, they were also Kokusan, but, fired 9 sparks per rotation, one spark in all 3 cylinders, 3 times per rev. They worked really well.

The zeel is a good ignition, but in need of a battery.
The krober parts can be bought new as Pitsch ignition.

Leon, thanks for the direct source for Pitsch replacements!

Hey Dave,
I've been using Jims Hobbs system in my H2 - no battery - for couple of years. Many others use them too.

Look for what you need here:

Barry, you'll still need a generator with that system. Something you don't want on a road racer.

Thanks Rod, I have used Nev's system, it uses stock pickups and can use stock coils. I had some issues with the stock parts and moved on.
