SOHC Posted December 8, 2022 Author Share Posted December 8, 2022 This seems to be the only way I can mount the carb, the early oil tank won't work with this frame, that oil tank on the bike hardly fits in because of the gearbox adjuster, with the carb at this angle I can fit the oil bath filter. 1 Quote Link to comment Share on other sites More sharing options...
SOHC Posted January 8, 2023 Author Share Posted January 8, 2023 Putting the carb on an angel was a stupid idea. I realisedthe oil tank I have is a Featherbed tank with a tab welded on to fit a Gardengate frame, it dosnt fit properly and clashed with the gearbox top mount. A friend of mine is giving me an early rigid frame tank witch will look better to. 4 Quote Link to comment Share on other sites More sharing options...
SOHC Posted January 18, 2023 Author Share Posted January 18, 2023 This oil tank will work, need to make mounting brackets. 4 Quote Link to comment Share on other sites More sharing options...
Popular Post SOHC Posted January 31, 2023 Author Popular Post Share Posted January 31, 2023 Made an exhaust, tube size was very odd and all I could find was EWR tube, I had half a bend in the correct size. Fixed the bottom of the oil tank, someone had brazed the drain up because they had lost the drain plug. I still need a clutch and pimary chain caces.

SOHC Posted February 6, 2023 Author Share Posted February 6, 2023 I spent a long time fixing the bottom of the tank but I decided it would be better to just cut it all out and start again, it was full of cracks and brazing. 3 Quote Link to comment Share on other sites More sharing options...
SOHC Posted July 29, 2023 Author Share Posted July 29, 2023 I found another WD Big 4 engine, it has the tappits and valve lifter I was missing, also the cam pinion is better than the one I have. Much to my surprise and glee this engine doesn't have lipped roller main bearings, they are about $400 a bearing, this just has ball race bearings. 5 Quote Link to comment Share on other sites More sharing options...
GregT Posted July 29, 2023 Share Posted July 29, 2023 Ball bearings will be fine as mains. I'd use C3 though. Where did you price the lipped rollers ? I bought a pair locally recently about $290 for the pair. Imperial sizing of course. They looked at their records and said I'd had them before. This time they are for a AJS Stormer twostroke. First time was for a 500cc Rudge special. Same bearing. Quote Link to comment Share on other sites More sharing options...

When the waka taniwha had its 2nd blow up the maines needed to be replaced and they were over $600Â Quote Link to comment Share on other sites More sharing options...
SOHC Posted July 29, 2023 Author Share Posted July 29, 2023 Not super horrible, a new big end and mains should see the bottom end done, I may reuse that old piston. People reckon I should press the cams off the shafts and swap them over but then the ramps are on the other sides of the lobes. Gearbox is apart and I need a new 2nd M/S gear, I found a new 1st, I got given most of a clutch and a kick start leaver 7 Quote Link to comment Share on other sites More sharing options...
SOHC Posted November 24, 2023 Author Share Posted November 24, 2023 Went to Macintosh and got some clutch parts, still need a heap more but it makes the clutch so much nicer 4 Quote Link to comment Share on other sites More sharing options...
