Carb won't "fit" (please help)

    I really wanted this motor in this stretched cruiser frame. But a downward-sloping frame tube (under top tube) is preventing me from sliding the carb housing on. Do I have any options in getting this frame to work? (It's so close) Can I remount/reposition the carburetor by soldering a 2 inch pipe to get around that frame tube? This is so frustrating--thought it would fit.

    Thanks, Ryan

    Can u post some pics please Ryan?
    I've seen HT carby intake manifolds which are much long and bent to go around the side of the bike but i'm not sure how effectively they work...they must work though.Their for ppl whose carby's don't have a hope of fitting in the standard form,but without pics of your exact setup it's hard to tell.....there might be some other simpler solution.

    I agree, pics will help us brainstorm a fix to your problem
    there have been a few custom manifolds posted here already

    Thanks...I'll try to snap some photos this evening. Such good progress was being made on both mine and my wife's cruisers (Electra brand)...until I attempted to slide the carb on and noticed the carb won't connect. Looking forward to a hopeful resolution (instead of scrapping the frames, I do like them). I'm wondering how far away one can extend the mounting of the carb. :confused:
    Much thanks. Ryan

    Thanks, Scott. That's a good thought--unfortunately there still a lot more room in that frame than in my cruiser.

    If I rotate the engine mount more vertical then the spark plug connection is in the way. I'm really struggling with this one. Along these same lines, how does one fit a motor in a girl's cruiser frame (I'm also trying this for my wife)? Again, the motor fits up until the carb installation...ugh. Won't slide on the motor due to top tube or middle down-sloping tube. I really hope I don't have to buy two new cruiser frames. (But will if that's what it will take).

    ok, if you haven't already, check the "replacement spark plug" topic...i believe champion makes a pretty short plug that will buy you a bit more room.

    something like this homemade air cleaner may help, there is a link or two to more examples, also.

    is it possible to mount the carb to manifold, and then install manifold to engine ?
    that's how I had to do the carb on my deviate
    or is the space even less?
     
  9. I seen somewhere on this forum where a dude modified his manifold to go AROUND the frame and thus have the carb a little out but it looked cool like a motorcycle blower assembly.
    But were really gonna need pics here.

    I would think that having the longer manifold would definately effect the performance. If the fuel is turned into a mist and then traveling a longer distance than the spray point was designed, it would probably turn back into a liquid state and although it might run, it would be a real kink in the power aspect.
    Think of a highrise manifold in a car is a little different because it is spraying downward and you can adjust the spray to go a little wider because most vertical highrises taper outward in their journals. Where as a horizontal would be more apt to fall to the laws of gravity and liquify on the way to the intake port.
    Just another opinion, for what it's worth.

    OK. Here's a photo of mine. If I rotate the motor back, the sparkplug and housing collide with frame tube. And forward, there's no room for carb. Is this one hopeless? My wife's is an even signifantly more restrictive space. So very frustrating!

    Thanks, Ryan

  12. That first pic looks like you can almost just flip that manifold upside down.

    Here's the bike I remember.

    He used two intake manifolds but I'm thinking if you can cut yours between the elbow and head mount then get an elbow from the local hardware store just slightly larger inside diameter so both manifold ends slide in then when you get the right angle,epoxy the ends.
    Do you follow me?
    Or where you cut if you can just get a short straight pipe just slightly larger inside diameter slide both ends then you can TURN the carb end so it will clear.
    If you do it this way,then you won't deal with potential problems for your manifold is too long.
    Take off your manifold and go to your hardware store. Check the copper pipes or what not and try fitting the manifold from the carb end and get a snug fit.

  13. Oh look! He used silicone heater hose.

    Maybe then a couple of hose clamps and you're golden.

    Man I just looked at your wife's bike again.
    Even if you get that manifold right,look at your clutch arm.
    You're entirely better off getting a men's frame for your wife's bike.
    ...maybe get another frame for you too,but you can probably get by,your wife's bike no way.

    (edit again)

    Another problem I see. On your bike that engine is angled so much you needed to take that clutch cover off to clear the chain? Then how you gonna work the clutch?
    Another frame,keep your components.
    Much much less headaches.

    Those pics make it look pretty hopeless to me. Unless you are willing to cut and weld, I'd try for another frame. Sometimes, it just can't be done.

    YMMV.

    Ya, I gotta agree with Mickey. Even if you got it in there, the float would be at such an angle it would probably never close the fuel off or the reverse, you would be off all the time.

    Thanks all! I greatly appreciate all comments. I will concede and look for two additional frames. (sometimes it just takes too much tinkering to get where I want to go). The women's cruiser bike motorized has really stumped me. Thanks, Ryan

    Don't give up!
     
  18. Just a thought.
    From the spooky site.
    For the wifey!

    I actually want one just to have actually.

    Amazing the tight spacers these little buggers can fit into,that's where they really excell.......unfortunately 4-strokes can't come anywhere near that.

    Thanks for the idea. You are right on! And that's what we're going for. I'm going to call Spooky tomorrow and order up a metallic burgandy for her and some parts for my new frame. (I'm taking one of their camo military bikes and making it into a camo version of the hot shoe racer. The idea is to have a matching motored bike to our incoming Ural sidecar outfit--now just have to make detachable sidecar for bike.) Now these two frames had better work/fit....
    Thanks for your thoughts!
