    Picked this up for the kids (ages 4 and 5). Its Tiny, only 34" wide.

    Original engine was a no name 50 or 80 cc, it has been repowered by a Honda GC 5hp by the pervious owner, which is more than enough for this little thing. For sure will be dialing back the gas pedal stop, it did 18mph with my 175 lbs in it!

    It has a centrifugal clutch to a jackshaft, so some options to regear if needed. At first I was worred I was going to want a CVT but I think it has plenty of power to get moving with that big of an engine. Doesnt slip the clutch any with me in there. Will see if it has any problems on hills with the kids.

    Plan is to add a remote kill setup so it can be shut down by us if needed. Will put the stock gas tank back on with spacers (to clear the valve cover on the Honda) to provide a shield to prevent them from touching the engine when in the seat.

    Eventually would be cool to put an engine with a charging system on to run lights.

    Maybe even widen it out as they get older and drive faster.

    Will need to find 2 kids helmets, hoping some pop up on craigslist.

    They have not seen it yet, going to wait till christmas.





    Hammerhead still makes a buggy this size and not much has changed other than having a 136cc engine and CVT.

    Those came with a whopping 47cc weedeater engine that couldn't even pull up a slight incline. Look for a cheap used kid's 70-90 cc atv, putting the a-arms from that on the front end like I did makes it soooo much safer. Cool beans, gonna be two happy lil campers! did you smack the back of your noggin on the cage a few times? I still haven't finished sanding my daughter's down for its repaint. Had hoped to have it out for sale pre-christmas.

    Safer because wider?

    Naw I'm 6'3" tall. I was sticking out the side.

    Scored these off craigslist tonight. Hope they are small enough.

    Ha ha .... my wife would freak out if my son came around the corner like that. Of course, I would give him a high five.

    Last night moved the pedals back to shortest position and made some spacers that will allow the stock fuel tank to mount above the engine. Want it there as a heat shield. Going to add the throttle stop, and maybe shim the engine to tighten up the chain then it should be ready to give.

    Also want to add the remote kill. I think I have one picked out.

    Cool stuff Mike!

    Engine looks like a big block sitting on there!

    Post some dimensions, I'll draw a new upper cage with BT. LOL!

    EDIT: that passenger is in for a surprise sooner or later.

    Added gas pedal stop and finished gas tank mounts. Pulled the carb off and apart and ran through ultrasonic cleaner. Was dying at idle but ran fine at higher speed so hoping idle passage was blocked.

    Going to redo the throttle return spring correctly while I have it appart.

    Will get a feel for if it will run slow enough with the throttle stop or if will need to regear once I get the engine back together.

    Had to rake shut the trenches I cut in the gravel hooning around last night...
