    Default If you had a nickel for every Sporty build thread...

    Let's hit the ground running here. Started to work on this in July 2011. Plan was to cut the seat tubes and replace them with downward sloping tubes to mimic a brat style bike. Then I said fuck it and proceeded to cut the rear off completely. There was a lot of downtime because I was a lazy piece of shit. The bike was in my mother's patio and I hated going there to work on it so it sat and sat.

    Before pic [i had a different tank, you'll see it in the background in the next few pics]


    Tear down


    Original plan - sloping seat tubes


    Next idea - front & rear 19" mags [pic just for kicks]


    Fuck it. Hardtail it is!


    My "jig"


    Used this:


    To do this:


    Got this after notching with a grinder and files.


    It sat like this for months. My friend said the notch in the tube to the axle plate wasn't safe so... Moved location (friends garage) and started over.


    Wised up and built a jig (and i got free 2x2 steel from my friend)


    Another shot on the "table"


    Bottom tubes/rails. Notching with a grinder and file takes time.


    Friend welding it up


    On its wheels to see how it sits


    Transporting the engine from mom's patio to friend's garage. Bitch is heavy!


    Working on a brace that'll weld across the bottom tubes to and bolt to the bottom engine bolts [can't see the brace at all]. Let's be honest, I just needed a pic of the bike and a beer.


    Random shot of the hardtail


    I got the oil tank kit from Bung Kings today with the SS bungs for the sissy bar. Need to tie up some loose ends and then start on the oil tank welding & mounting. I'll post updates as they happen.

    Thanks for checking in!

    Gonna add the tank I'm working on as well.

    Stock 3.3 gallon that came on the bike. Ready to cut.


    After the cut.


    Lining it up.


    Tacked.


    Marking the bottom.


    Bottom - cut & fitting it.


    Welded it and just sat it on the bike, The exhaust pipe is holding it up. haha


    Going to cut 3/4" from the bottom because I don't like the look of the rounded bottom.

    Nice tank! Really cool shape. How much fuel will it hold, 1,5 gallons?

    Thanks. Since it isn't finished, I've yet to measure its capacity.

    Very nice build so far and great job on that hard tail. I've always wanted to make one from scratch and that looks better than my store bought one for sure.

    I think it came out too wide but it was a learning experience. My friend recently got a tube bender so my next plan is to make a whole frame out of 1"x.120" and keep it narrow and probably long.

    I always dig seeing someone put together a build with meager resources. Building on a patio or cinder blocks in a friend's garage is cool by default.

    Anyone else think that Sporty builds deserve their own section in the forum? You know, American bikes and tech, British bikes and tech, Japanese bikes and tech...Kingdom of the Sporty...

    Welding on the frame/hardtail is completely done now. Need to clean up the welds on the hardtail/axle caps then I can prime it to prevent rust. The oil tank is tacked up and the mounts on the frame are fully welded. I have all the stainless steel stock to build the sissy bar.

    Currently working on the wiring. Heavily considering redoing all the wiring in cloth wire and leaving it exposed.

    No pics right now.

    Oil tank mockup/mounting


    Ready for my friend to TIG it up


    Oil tank mounting points


    Mounting the fender - the radius is off, i know


    My superb welding skills /sarcasm


    Considering passing the wiring through the backbone and redoing some of the exposed wires in cloth wire.


    Need to work on the rear brake and get some spacers for the rear axle. I'm going to remove the surface rust & prime the frame tonight or tomorrow.

    I have the last few parts I need coming in this week so I can start putting it together. Also going to clean the crap out of the engine and going to radius the fender when I get the new rear wheel/tire and remount it and start the sissy bar.

    Removed the paint from the front half of the frame.


    Primed the whole frame.

    It's gonna feel like Christmas this week. I have the chain, clip master link, seat, front & rear wheels and a rear tire coming in. I hope I get all the parts this week so I can work on it all weekend and get it painted and ready for final assembly early next week.
