Suzuki 2 Strokes

Thank you up-front for any helpful answers. I did a search and couldn't find what I needed.

My bike is a 1975 GT380. I have NGK BR8EIX Iridium plugs and LZFH caps. The bike also has a Petronix electronic ignition if it matters....
Q: What gap should I give the plugs?

I have Iridiums in my own 380, gapped at 0.6mm / 24 thousandths, which works great with the standard points ignition, I'm also running total-loss electrics (until I get the rotor rewound).

You could probably use a bigger gap but 0.6mm works just fine for me.

If I'm not mistaken. I'm pretty sure that manufacturers suggest against setting gaps with iridium plugs. They are gapped for specific specifications when they are made. Plus, it has a large part to do with the electrode being smaller. They aren't designed to be gapped like ordinary plugs.
