I'm just finishing off my Flying Brick to take to Spa next month after another crash.
I'd broken a ceramic insulator on one of my other plugs so I thought I'd try these. You can see on the box what Brisk claim so I wondered if anyone else had tried them?

I tried something similar a few years back. Nippon-Denso (I think) started producing plugs with two return points; it turned out to be just one more area to clog up with carbon. They didn't stay on the market long; personally, I showed them the bin long before the normal usage period because I got fed-up with constantly cleaning them.

Hmmm. Hopefully carbon deposits shouldn't build up inside my engine-I normally change up at around 8750 rpm.

Closest I've tried is a surface gap plug on a Mercury 2 stroke outboard. Very non-fouling in that difficult environment. (NGK BUHW)

What is the gap on those ones?

I'd be very interested to see how they perform for you.

Bill

Hi Bill,
They're in the bike now and I didn't measure the gap as it's none adjustable. I've just installed a set of Bosch XR7LDC's in my K1100LT and they were an improvement over the NGK DR7's I removed so I'm hoping for good things from the Brisk plugs.
It seems like I'm the 1st to try them!

I'm probably not the only one curious about how they perform. I was wondering about the gap because it looks very large. I wouldn't want to use them on a conventional Kettering ignition system!

Bill

Well Bill, the gap is factory set so we'll just have to wait and see. I'm more than likely going to take round the country lanes where I live for an unofficial and very illegal road test in the coming week.
I'll report back if I'm not arrested in the process!

Great excuse. If I need legal representation are you available?

Our legal system will probably make you join him.

No, no, no, that was back in the olden days.
Our legal system now welcomes any old shit into the country and they seldom get deported even if they commit murder, rape etc. Don't you just love the UK's new ways?

Are these compatible with early K resistance based ignition.

I think they are. Here's the table I used to check.

hope the heat range is close to factory

good idea worth pursuing with new ideas .. but a little off the radar for most folks not into race performance concepts (...um read exclusivity ...expense and replacement availability) ...some folks just love "cruising" as many in here appreciate with reliable outcomes

good to see


thanks

If I'd seen these before I bought the Bosch plugs I'd have put them in my K11 too. I've tried NGK Iridium in my other BM's before and felt an improvement over a bog standard item.
There's no harm in having a good set of plugs! 👍
