    Awesome, thank you. The flanges I have are dead on and will work perfectly for transferring over the bolt pattern.

    blm would you post up a pic of the transfer plate used to locate the new drill/tape holes. Also what's the bolt circle diameter and the OD diameter of the turned down 70 hubs? I'ved seen several go kart wheels/tires at our local swap meets recently and thought about how to mount them.

    What I did to drill an American kart pattern on a Honda hub was to turn a shoulder on the hub that fit in the center bore of a 5x2 wheel half from a modern quarter midget, and used a large bolt and washer to hold the whole assembly down in my drill press. I then used a good 1/8th drill bit (not a cheap one that bends, found that out the hard way) and an adapter that fit in the 5/16 bolt hole in the wheel with a 1/8 centered bore, then stepped up to an appropriate sized bit for 5/16-24 (escapes me at the moment). I threw a bolt in the holes to prevent the rim from rotating, turned the hub and rim half and reapeated for the other two holes.
    It spins true on my lathe and looks pretty good with 12x9.00-6

    Nice job toast. Those look really nice. Hairy, the od is 3.5 and the bolt pattern is the American kart 3x2.5. I turned a shoulder just like toast did to center the ring and used a center punch to mark the holes. I'm drilling and tapping these for 8mm 1.25 studs/bolts. I don't like the 1/4 kart bolts and actually broke one racing my 250r, so I drilled them out to 5/16-20 and never had a problem after that.

    Any recommendations for wheels and tires? I don't know a damn thing about modern Kart stuff, other than there seem to be endless options. I want to get out fairly cheap, and its just gonna be a mess around rig. Going on a 150 Piranha powered 5 speed 70.

    What surface are you riding on? I ran Hoosier treaded dirt tires.

    All of em'. Probably mostly hard packed dirt trail with some light sand. There is a small small little loop at a spot near the power lines i'm hoping is gonna be fun. Other than that, grass and pavement. I'm looking to spin them. I was looking at those hoosiers on eBay. Seem to be very very reasonable wheel/tire packages. Should I look for anything other than the 3x2.5 pattern? Width? Offset? Height? I was thinking 5" or 6". I don't really know. I'm open to suggestion.

    I only ran circle track so ran stagger. I ran a 6 inch wheels. 12 inch tire on the right, and 11 inch on the left. I forget how wide the wheels were? Really if your not racing, I'd just get 6 inch wheels in America pattern and the treaded hoosiers.

    You ran those wide tires on the 250r though, right? Not on a little guy? My main goal is to try and keep the front down so i can steer this thing.

    They also make a dirt slick. Those treaded tire gotta lot of bite.
