    New Pumper Carburetor for T-Dub

    Someone on this forum posted a link for this carb in the beginning of this year but unfortunately I couldn't find the original post

    Anyway, US $47.66 for a brand new carb, cables and a throttle housing grip and 2 pro taper grips was an offer that I couldn't ignore so I proceeded to order one from China on Ali Express

    I'm going to have to wait around 2 months for it to arrive and then I will report back to let you guys know if my purchase was success

    Go to https://www.aliexpress.com/item/KEIH...460.0.0.TERXPN







    Oh, and by the way, the Cornshield received a proper wash today

    Nice package deal.I always thought a pumper carb would be an excellent upgrade.
    Will you be able to anticipate and pre-order parts for starter button, kill switch, inlet and outlet boots for 28mm to 30mm conversion plus jetting parts? Might have to wait until carb arrives to take dimensions of some of this.
    If you can get it to work you will have earned one of these: MissingLinkMasterA.jpg

    I too bought one of those manifolds thinking it would work on the TW. It didn't. The angle was wrong. The manifold I bought didn't have the vent tube. I ended up trashing it trying to make it work.

    The manifold I got over compensated. The carb was still at an angle only going the other way.

    Is there enough material to allow you to turn the carb outlet down in a lathe ... make it a slip insert fit like a stock setup?

    I would have to say no. See 3rd picture above in post #4.

    Woohoo!

    After waiting for more than two months my pumper carb finally arrived!

    I'm tired of cruising a mere 75 mph, with this new high performance pumper carb I'll be able to cruise at around 80 mph on the open road

    Ha ha, no I'm just joking, this carb just picked my curiosity because of its good price and my present original carb is still working but its age is beginning to show so I decided to go for this one






    Is says "KEIHIN technology from Japan" on the carb, just give me a day or two and I will report back on my findings



    So if you guys will please excuse me, I've got some work to do, I'm not going to rest until the carb is on my bike . . .

    ...and the kit comes with the correct pillow top grips for comfy 80 mph cruising on the open road. What a deal!
