Topic: Keyster "Carburetor Fuel Adjustment Kit"? 750 but have for other models too

[Garage_guy_chris]

Ok so i have been messing with my 750 carbs and working on tuning. Tonight i was screwing around looking for parts and stumbled across something interesting on japan.Webike.net.

I found these "Carburetor Fuel Adjustment Kit I havent seen anything like this before and they looked interesting maybe someone could translate the japanese writing on the instruction page? That would probably reveal more info on them? Other than that anybody used then or heard about them?

they have 2 models:
FH-0024N    Fits:HONDA  CB750K  K0-K1 K0 after period
FH-0134N    Fits:HONDA  CB750K K2  ( i assume works on K2-K6 linked round tops as there basically the same during this period)

This is the page and info for the FH-0134N

they appear to have a whole bunch of stuff to fine tune things like:
- 3 pilot jets; #39 #40 #45
- 6 main jets; #104 #106 #110 #114 #118 #123
- 4 needles; 1 matching 27201 needles and 3 others with different start diameters and tapers.
- needle jet
- air screw and spring
- fuel valve
- float bowl gasket
- Drain screws

Looks like for an earlier model carb. First I've seen of a kit like this. Wouldn't this be great! I did Keyster once but took out the jets and re-installed the originals with better success.

I did a search with the Keyster part number and it tagged it with malware so I quit.

I'm using Google translator while in Panama. Give it a try. Muy bueno.

I updated the original post with a little extra info on application while you wrote your response.

I also tried to search and find more but its all in japanese and I can't find anything directly from keyster just alot of japanese links that don't seem to go anywhere. How Keyster has no website in this day and age is simply mind blowing...

Funny enough im also having some issues with some keyster parts and a lean condition.
