Qlink/Konker/Qingqi Needle valve
I've been having problems with my carb leaking on my 2009 Qlink XF200. I would find a small puddle of gas under the carb if I left the petcock on.
I know... switch it off when I park the bike. But that just hides the problem. I pulled the carb thinking the float was off. But when I set it to spec the problem was still there. I concluded that I needed to change the float needle and seat. I found that the BS28 carb is used on a Kawasaki BN125 (Eliminator) and 1980's Yamaha XJ models. I went to my local Yamy/Kawy shop and we found a set for a Yamaha XJ550. I ordered it and it came in two days. Below is a pic of the package with the old set on the right and new on the left. You get the needle, seat. and a new screen. It cost me a bit over $23 with tax. Bike Bandit has the set but it's a bit more with shipping. I would rather get it local when I can anyway. I am happy to report that all is good after the install. As to setting the float to spec, I will post more below.

You were wise to get OEM parts.
Aftermarket carb parts quality can be hit or miss. The Q uses a very good Japanese Mikuni carburetor. The Q overall is a very nice motorcycle. How I wish I could still get them for $1,500 delivered!

Ok, getting the float to spec using the two manuals available was an adventure because neither is quite right. The english version shows the correct way to check it (setting the carb upside down) but gives the wrong spec. (30.5 mm). The Qingqi manual gives the correct spec (18.5 mm) but shows the wrong way to check it (on it's side).
I used Weldandgrind's method; upside down and align the seam in the floats, parrallel with the top of the float bowl. When I did this, the measurement was 18.5 mm and all is well. Thanks Weld!

Weld knows things and is a reliable source of information.
No pressure, Weld (LOL)!

I have done business at this shop before getting filters and the almost-mandatory speedometer cable. The counter guy was a great help and I didn't get the stink eye because it was a CB.

Thanks for sharing the good information which will undoubtedly help other QLink owners!

I used the same method last year before I put her up for the winter but still got a leak. I knew then it was time to bite the bullet and get the needle kit.
