I got some bits! For the record and interest:
Four wheels, tyres and tubes: New 16" cost $92 each (search "90/100 - 16" Inch Tire & Rim Rear back Knobby wheel BIGFOOT Dirt Pit Trail Bike" on ebay). These have 37mm bearings (but maybe 35mm is more versatile, see later note re spindles). Hub is 120mm wide, and 135mm wide counting the raised bosses. They have a 4-bolt 92mm PCD disc mount on one side and 4-bolt 99mm PCD cog mount on the other. On the rear, I will use 25ID/37OD bearings for my 25mm axle:(https://www.amazon.com.au/gp/product/B082PYT33D/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1)
and on the front I will use AZUSA 5/8" 6" long spindles at $102.09 shipped, on AmazonAU, with four (4) 5/8" to 3/4" sleeves, search "5/8" x 3/4" x 3" Shaft Adapter Pulley Bore Reducer Sleeve Bushing Sheave & Key", $48.05 shipped on aliexpress, and 3/4" ID to 37mm OD bearings, search "MR190537-2RS Bearing (10PCS) ABXG NB Spain axis bearing repair parts MR190537 190537 (6904 / 19.05-2RS) 19.05X37X9 Bearing" $36.11 shipped, on aliexpress. What a palaver!
"Trkimal Steering Wheel, 300mm Steering Wheel with Cap for Taotao Go-Kart & Dune Buggy Racing Cart Accessory": $56.12 shipped on AmazonAU
"Steering Assembly 20mm Complete Brand New w/Black Countersunk Washers": $145 on CPR Karts, plus some extra tie rods just in case $22.90, free shipping. I think I may need to lengthen the steering column.
"Vintage Type GO Kart W.A.O. Brake & Throttle Pedals": $42.05 on AmazonAU
"900mm 25mm Axle keyway running full length flexible sprocket disc bearing 4x110": $178 + $35 shipping on ebay. I'm reverse the splined 4-bold wheel hubs to secure my wheels - that is, reverse the splined hubs and have the wheel on the inside of them (and use the 110 to 100PCD adapters, below) rather than on the outside as normally intended for go-karts.
"2pcs 15 12x1.5 4x110 to 4x100 Wheel Spacer For Daihatsu Mira L200 L500": $71 shipped on ebay to adapt the 110PCD wheel hubs that come with the axle to the 100PCD on my wheels. I plan to use one (1) driving/braking wheel but be able to lock up the other rear wheel as an option.
"VEVOR 3/4" Clutch Go Kart Torque Converter 10T12T Complete CVT Combo 30 Series": $85.99 shipped, on ebay
"7HP Petrol Stationary Engine OHV 4-Stroke Horizontal Shaft Replacement Motor" from Edisons on ebay at $169 shipped (after 15% ebay discount).
"Azusa Predator 212cc Engine Mounting Plate - 5" x 12" from AmazonAU for $46.23 shipped.
"HIAORS 428 Drive Chain 102 Link with 5pcs Connecting Master Link" for $32 shipped on AmazonAU - possibly should have waited to get my driven cog before buying this chain.
Some 25mm "Mask machine accessorie 45carbon steel shaft collar bushing stop screw type bearing retaining ring ID 8-32mm Set Screw M5 M6 M8" at $3.19 each with free shipping from aliexpress.
"FL205 Transmission 2 Bolt Flange Housing and Bearing to suit 25mm shaft (pair)" from ebay for $43.95 the pair, shipped.
"2420mm(242cm) Throttle Cable For 200CC 6.5HP 9HP 270CC Dune Buggy GoKart" for $18 and "2.5M Bike Bicycle Universal Front Rear Brake Wire Cable and Housing Set" for $13.39, both shipped, on ebay.
"Front + Rear Disc Brake Caliper Pads Fit 47cc 49cc Mini Pocket Bike ATV Quad" mechanical brakes set for $32.60 shipped on ebay.
That was the easy part. Now I need to find a way to get all this into the shed and make it look like it's been there for years! Anyway, I'll be off to get some steel and some springs of some sort next!
Have fun!
Simon
