It’s a pretty minor item (*´з`)
but it’s effective, low-risk, and doesn’t fail easily.
What is the PLASMA BOOSTER?
“The plasma booster is an ignition tuning part that, by connecting to the ignition coil, increases the secondary current value to approximately double, and generates multi-spark (three or more sparks instead of the usual single spark), thereby improving combustion efficiency.
In particular, this multi-spark is generated in units of one millionth of a second, making it possible to sustain multi-spark all the way into the high RPM range.
Even fully tuned engines can keep up with its specifications. It delivers results across a wide range of driving scenarios, from city riding to competition.
So, what’s it really like in practice?
For older bikes, Watanabe SP2
It’s really hard to define what counts as an older bike, but let’s say anything before the 1990s.
Whether they’re points-based or fully transistorized, older bikes definitely have somewhat lower reliability, so I’m definitely pushing Watanabe SP2 (‘ω’)ノ.
So what about oil-cooled bikes and all that?? (*´з`)
If your coils and igniter aren’t currently having problems, or you’re not experiencing mysterious ignition issues, I think the stock ignition parts are the way to go.
With Suzuki OEM parts, I’ve seen coils fail, but I’ve never seen an igniter go bad.
That’s how reliable the electrical system is.
Watanabe is a consumable item (*´з`)
Yeah, really?
Of course, some people get a very long life out of them, while others see them fail in no time.
Since it’s an electrical product, that’s just how it is, in my opinion. But sometimes there’s a gap between that reality and customer expectations.
The unit can get sketchy before the coil does.
I’m not saying anything bad about Watanabe—I’m just saying that if you use it long-term, there’s risk.
In the worst case, your engine starts and stops intermittently, which is a real pain, and if it happens out on the road, it’s incredibly frustrating. I want to dramatically reduce electrical system risk.
The plasma gives a smooth feel and has a safety circuit!
With the plasma booster installed, cold starts improve slightly and the riding feel becomes smoother.
You get the impression that it’s burning well. (Though you get used to it pretty quick.)
And if the plasma ever fails, the circuit is designed to keep running on normal ignition, so you might not even notice—but that’s reassuring.
To really feel the difference, you have to install and remove it repeatedly.
Like everything else, the placebo effect is working at full blast!
It’s running wild in people’s heads…
I don’t believe in anything, so I make things easy to install and remove, and I repeat the test at least 10 times before I believe in something absolutely!
But even with that absolute standard, some things are 103 instead of 100, and some are 120.
Sketchy stuff is like, hmm, 100… forever…
Engine oil quality is the same way. In similar conditions and usage patterns, I think the best approach is to drain and change it around 500–1000 km and give your impressions—that minimizes variation.
I’m a plasma booster guy on all my bikes (・´з`・)
It’s easy to install and remove, trouble-free, and has a safety circuit.
You can feel the difference almost 100% of the time, so it’s basically a staple for me.
Even the CB1100 SC65, which I thought wouldn’t change, did change, so I think it really works. If you’re unsure, definitely try it (*´з`)
