After replacing the cam, the idling is a bit off.
It’s not that I can’t ride it, but it just doesn’t feel right.
I thought it would go in the “rich” direction, but
when I checked with PE WIDEBAND it was “really lean”….
I tried to fake it with PS…. and it got a bit better.
The CVK needle can’t basically change the number of steps ( ;∀;)
As expected from Keihin. Don’t mess with it, huh?
I was wondering if there’s a needle where you can adjust the steps…. and while patrolling….
[Domestic Product] Inazuma 400/Inazuma 1200 New Domestic Original Needle Kit
And it was also being sold on Rakuten.
Since I couldn’t really get any information from anyone, I picked it up as a year-end toy.

The stock one can’t adjust the needle position like this.
I wished it had the flexibility like Mikuni ( ;∀;)

At first glance, it really looks like a stock needle shape.
It has a gentle taper and a stubby straight diameter.


It’s packaged carefully like on the left.
Is the appeal of this sharp tip the reason for making the needle longer?….
It’s a pretty unusual idea ( ;∀;)

The lengths are different. I’m a bit worried… actually quite worried….

The image is a stock CVR (for GS1200SS) fully open.


The straight diameter is a bit thinner, which I personally like.


The Inazuma 1200 hasn’t had its carb disassembled yet since I bought it, so the slide valve is dirty.


I basically don’t do much with carbs,
but since it’s mine…. I wet blasted it.

Once the fuel it was craving was supplied, it got better.
I don’t want you to misunderstand, but this is an “adjustment needle” so just installing it won’t give you performance.
Also, I’ve only lightly ridden in this area, so there are still many unknowns.
It might be fun to do some tuning yourself or play around a bit.
I wonder what effect that pointy tip has.
Carburetors are great (*’▽’)
