Keihin carburetor jet type for (139qmb)?

[Deleted]

I order main jet #88 for my kymco people 50S 4t last week.
I receive the jet #88 but it didn't fit in my carburetor, the tread is to big! :banghead:
I think it fit on Harley Davidson, they also have CVK carburetor but with bigger main jet...

I want to know, what is the type of the main jet it go inside a Keihin CVK for a scooter 49cc (139qmb)

I see the have type: KJ, PB, MR...


Thank's!

Where did ya get the jet from??? They may have sent the wrong one. Check out Enviromoto or Scrappy's and specify a jet size for a Qmb engine. This is a very common part for scoots but, If you went to a motorcycle dealer they may not have a clue.

Then again Kymco does use some proprietary parts different from a typical GY6 clone.

I think just getting a Keihin or Walbro carb CVK jet should work. Just my .002 someone else may have better info but I run an 88 from Scrappys with no problems on my QMB.

I found this on the web but not sure is ok!?
The carburetor for the 139qmb is a KEIHIN serie PB and they use jet 99101-116 .

What do you think?

That should be right.

I receive and install the jet serie PB and it fit #1 on the KEIHIN carburetor!
