  1. A small package with lots of mandarin writing on it that I can't read arrived today. I get pretty dam excited by these, it's like Christmas everytime...as I've usually long forgotten what it could be inside, so its always a fun surprise opening them up. Ah yes, I remember...a choke cable. No, not the one my wife ordered from the 50 shades catalog (we're still waiting on that one), a choke cable for the harley. Looks easy enough to install, I'll just unbolt the old fucked one and put it back together with the new replacement as it's a direct factory part eh? Ummmm no...
  2. Okay, it's no secret I'm into some pretty niche things. Gopeds, drift trikes, lowrider bikes, skateboarding, gokarts, tallbikes, etc...etc... none of them are popular in NZ by any stretch of the imagination. Now this is about as niche as it gets. 39cc of polini awesomeness! It puts out 6.5hp and sounds like an angry beehive!!! Pops wheelies when the powerband kicks in...its mental. I picked it up a few years ago, with the goal of cutting it up and putting the motor on a goped. As it turns out, its basically the grandfather to the pocket bike craze and is highly collectible in Eu
  3. Fuck yeah, that looks awesome as is. Those proportions are spot on! I'd leave those wheels on it just like that. My mum was an avid designer/landscaper and she always said it really doesn't matter what or how something is made, as long as the proportions are right, it'll look amazing. That's why certain cars look so good, yet they are just cheap crap cars...and other cars that have had hundreds of thousands spent on them look like shit. If the proportions/scale is wrong, it'll never look good.
  4. My exhaust had a terrible bracket on it that sucked! My OCD couldn't handle the fact that the two pipes weren't parallel. Over a 400mm section where they run along side each other, the gap was out by 10mm from front to back. I saw this as an opportunity to fix two problems. 1) make it look right to the eye 2) raise the lower pipe by 15mm and the upper pipe by 5mm. This will really help with ground clearance, maybe not completely solve it...but certainly won't hurt. So: Marking out, lifting the holes by 10mm. And looking at the pipes
  5. They are a bead lock system. Its likely missing the internal bit, which is just a tab that clamps down on the bead. It's for hardcore karts that have so much power they'll spin the rim inside the tyre. By hardcore I mean shifter karts like 250cc 2 strokes etc... I wouldn't worry about it, as it's not going to be a problem with less than about 40hp. On mine, I mixed up epoxy and glued them in to seal. Then cut the protruding thread off on the inside rim section with an angle grinder. You could use thread sealer like loctite if you happen to have it on hand? Held air for like 6 months
  6. Sorted! I put little 5/16 cap head screws at the end of each shelf, to stop any round materials from rolling off, though I doubt its really needed (better safe than sorry I guess).
  7. Cut down the quad bike hubs to fit. Normally about just below the holes in the original hub (but measure first). Then redrill to suit gokart hub. I'll try find a pic on my old phone. Lathe is an advantage...but not totally necessary.
  8. I'm a total storage slut! Love to have a place for everything...and everything in its place. So: Steel/storage racks. I can fit anything from 0.6m to 3.6m lengths of steel/timber. The racks start at 1225mm so I can fit a sheet of plywood or whatever under it leaning against the wall. I feel another shed tidy up coming...
  9. My chain tension (lack of) was going to cause issues, due to the combination of parts landing on a half link. I started making a chain tensioner device, but I was struggling for room. I kind of mocked up a working solution...but I wasn't in love with it. Then I had an epiphany...i could add a spacer block under the motor to lift everything up to create the desired effect. So that's what I did. I can fine tune with the threaded rod and pivoting engine mount. That was always the intention, however it would be asking too much to move it as far as I needed to, just t
  10. On a roll...arrow stand made from a sports cone and the vaccum tube from a leaf blower...
  11. I've had this for over 30 years. Its had 2 other handles in that timeframe and on Wednesday the last handle broke again after 20 plus years...so onto No3... Took the time to reshape it a bit more this time. When I say "took the time" I'm talking 5 minutes to glue it together and then leave it overnight...and about 10 minutes tops to shape it with a flap disc.
  12. Fuck yes! The pcv valve solved so many problems. 1) oil leak from rear of engine, where old road draft tube was = gone! 2) Stinky engine smell that permeates the cabin = gone! 3) heat sink to carburetor issues causing fuel evaporation = gone! Well my 20km return trip with 4 stop/starts didn't have any issues, so maybe prematurely judging this one...but I'm calling it a win. I ended up blocking the road draft tube hole and using a more traditional setup out the valve cover. Main reason was due to oil separation. Someone removed the can inside the valley that separated oil fr
  13. Made this today, I'm testing out a potential offset option. Only way to see if my idea is heading in the right direction is to mock up a wheel with this to check clearance. And offered up to the rear hub Boom! Like a glove!!! Theres still 10 plus turns of thread engagement on the wheel studs, so pretty happy with that.
  14. Something that I've been putting off for a longtime. Not sure why, but I hate making solid round bar into tube...knowing that I could buy it with a hole already in it (but never do, becauseI don't need 6m of random tube lying around afterwards). Anyway: Working out a baseline to start with. Doing the part I didn't want to do. Took less that an hour start to finish...so I'm not sure why my whiney bitch side of my brain took over here? But 4x "tubes" precision engineered to within near perfect digital vernier accuracy of each other. Setting out the sprocke
  15. Kids and fucken chickens! Been tripping over them all day...
  16. Helped a friend with his deck, turned out pretty sweet. He'd made a few compounding errors that got away on him...I helped straighten it out, well at least it looks straight now, even if it isn't really. I've made him some floating steps, 1 on one side, 2 on the other. Ran out of time today (12hrs, no breaks) and my brain isn't working. Shit, shower, shave and I'll be good to go again. All he needs to do is wait for concrete to dry and slap on the boards for the steps which are framed and ready to go.
  17. Okay, after literally hours of interweb reading I'm slowly becoming more enlightened. The penny dropped when I discovered that there are 2 ways/types of pcv valve, both ways essentially achieve the same thing. 1) a tapered shaft, which restricts flow at high vaccum and allows more air to pass at low vaccum. 2) an upper and lower seat, does same as above. So at high rpm, low vaccum the valve flows heaps. At low rpm, high vaccum the flow is severely restricted. Which brings me to size? I hear it really does matter...well that's what my wife says. But how big???
  18. Picked up a couple carburetor spacers at kumeu. I've decided to use this one (below). No real reason...but I just like the secondhand one better, it feels solid, with nicer finish and just looks better made to me. I brought a nipple to go into it. Marked out. Drilling it so I breakout the centre of the 2 first holes. My manifold is edelbrock dual plane, so I've drilled and ported so both sides/planes will get the shittyness of the blow-by fumes equally. I used liquid epoxy (cold weld) to seal the 3/8" ID hose to 1/4 BSPT fitting to avoid vac
  19. Need an inline pcv and an air filter 1/2" lower to avoid potential issues with rubbing. But this is the plan for my vaccum source for the pcv.
  20. Soooo... Turned the tig up to "eleventy" and gave it some jandal!!! I ran it over all the mig welds and melted them into the parent metal hard core. Then used a heap of filler to create a 45° web in the highest stress points. I'll smooth the corner fillet weld a touch more with some sandpaper or flap disc (wont need much) and call it done, then send it out for chrome. Actually really happy with it now.
  21. I suspect it brakes in the sharp bend. I was toying with the idea of backing it up with a fillet weld, so this is convenient timing talking about possible cracking issues...so I will do that now as cheap insurance.
  22. How did they fail? Did they crack along a stress line? How did you remedy it? Keen to hear about your situation and how you solved it. I was going to lathe up some round plugs and bend some round bar kind of like this: But by the time I found somewhere for the choke to go, it seemed a waste of time. I may still go down this route, but I'm obsessing over small stuff that really doesn't matter.
  23. Hot metal glue gun action... Bolts are for pussy's!!! Functional, but far from sexy. That probably describes most kiwi woman...and this bracket falls into that category too. I'll get it chromed and it should disappear and not draw attention to itself.
