Popular Post Vintage Grumble Posted September 15, 2019 Author Popular Post Share Posted September 15, 2019 So I had a short list of things to sort after the last test. First was to make a more permanent restrictor, before the tape went through the carbs. I did lots of math to work out the area, and made a stainless restrictor, but just fitted it temporarily in case it was wrong. Turns out it doesn't work as good as the tape, so will try again. I also redid the top of the brake pedal, to try get more swing/feel. Seems to be a bit better/good enough. Did a bit more of the wiring/cleaned a bit of it up, and mounted the magic boxes. I'm waiting on some components to arrive from China so I can finish this and the dash. Speaking of dash, I started making a new one, with new switches and shit. Waiting on new warning lights to show up. This is the same shape as the hood. I also made a new front panel. It's made of thicker steel than before, with more bars and more mounts, so should be nice and strong. I also fixed a few other bits and bobs, and adjust a few other items. In testing today I discovered the sprocket is still coming loose, I think it's because the axle was welded together under the sprocket (it broke years ago because there was no center bearing) and is slightly undersized, and the key ways are a bit flogged out. I was going to re-key the axle and sprocket a size bigger to see if it would stop it coming loose, but while doing beach donuts, it snapped the axle. So I'll just make a new axle from scratch out of 4140 center-less ground. Luckily I purchased a 4wd last week, and I sighted this very occurrence as my reason for needing one. We managed to drag the offroader back to the trailer with a jammed rear wheel. My fucking sweet rig, Broken, Aftermath, Shitty vid of today's efforts: Regards, VG. 18 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Vintage Grumble Posted September 30, 2019 Author Popular Post Share Posted September 30, 2019 Yeh nah yeh, so after that ^ I got a bit of 4140 CG shaft, had some keys chucked in it for a box, and slapped it back in. Keys are tiiiight and everything fits much snugger due to shaft being correct size, so that's tops. I cut the keys a bit longer, so everything had a key under its total length for strength, and I went for internal threads on the ends as its way easier to do. Once it was back together, we took it back to the beach again, to finish off testing. It was running much better (put tape restrictor back in) and we thrashed around in it for hours with no dramas. I didn't get video of it, but i'm blown away by what it can get up, considering it has no articulation in the rear. It was strolling up stuff that decent 4wd's couldn't get up. I tried to keep the vid short, and not totally mind numbingly boring. You can't really tell in the video, but the road is bumpy as all heck, quite pleased how well the suspension works for how shit it is/road bike shocks and pivoting on bolts. I accidentally drove it through a few small streams on the beach, so washed it down when I got it home. While pushing it back into the shed I discovered one of the back axle bearing housings was broken, I think it may have been damaged when the axle broke, as its on the side that got wrenched around when we were towing it off the beach. By reviewing the footage, I worked out it broke on the last run of the day, so didn't do any real damage, thankfully. Hows that serenity? I decided if the suspension and steering didn't break after all that testing, it was probably good enough, so stripped the whhhooollllleeeee thing down for painting. So now i'm going to clean up some welds, cut out some weight, and then paint it. Regards, VG. 14 1 Quote Link to comment Share on other sites More sharing options...

kicker Posted September 30, 2019 Share Posted September 30, 2019 Nice looking shaft! What kind of torque can the keyed shaft handle? Might need something myself but the calcs online are confusing. Quote Link to comment Share on other sites More sharing options...

I have to make the seat adjustable actually, as its set up for me now, a lot of peeps can't get near the peddlers. I'm not saying yo short, you just reminded me. 4 minutes ago, kicker said: Nice looking shaft! What kind of torque can the keyed shaft handle? Might need something myself but the calcs online are confusing. I have no idea to be honest, I'm just rolling with what it had. I may have to look at another set up if it fails. I've been told tollock bushes are pretty good. 2 Quote Link to comment Share on other sites More sharing options...

You mean because you go over the screws about 200 times before they come up to torque? Lol 1 Quote Link to comment Share on other sites More sharing options...

Yeh I could back-to-back them, but I'm fairly sure they are grunty enough as is. I'm certain it got damaged when the shaft broke. 1 Quote Link to comment Share on other sites More sharing options...

Popular Post Vintage Grumble Posted November 1, 2019 Author Popular Post Share Posted November 1, 2019 So this thing is still in a million bits, I'm still in the process of painting. All the bolt on bits are done, just have to finish and paint the frame. I wasn't happy with the battery tray thing, so going to redo that with a box of some kind. Story time: So a long time ago I got plans for one of these, I started collecting parts, but when I realised the cost and time involved in building one, I canned the idea. I had already purchased a second hand set of front callipers/discs/stubs from one, but the guy kept the hubs. Recently Edge products in OZ had a sale on, so I ordered the missing hubs, so I now have the compete set up. So sometime in the future I will make new front arms and put these bad boys on. I'd like to put flasher shocks on all round too, but they are spendy. Ages ago I also got a nice set of alloy rims and tyres from a racing ATV off trademe, they were listed retardedly so got them super cheap. And in a stroke of luck, the front rims are the correct PCD for the new braked hubs, neat. The back rims don't fit on the current hubs, but I've started collecting parts to make an independent suspension set up for the rear, so will make new hubs to suit when the time comes. Other than that, I've drilled some big ass holes in the 12mm plate at the back, to try shed some weight, and make it look racey. I also got offered an absolute abomination of a go kart for a box of beers, so got it against my better judgement. Its based on a kawasaki quad with a weird name that I can't remember, has front discs even. I'll probably just keep the front suspension and steering, rear axle and all the wheels, and bin the rest as its super grot. Plan is to make a simple two seater for the wife n kid to blast round in. Probably 13hp lifan with cvt set up or something. It has a 2 or 300cc honda atv engine on it, chain drive with low range, if anyone's interested?

Popular Post Vintage Grumble Posted January 27, 2020 Author Popular Post Share Posted January 27, 2020 So a while back I gots ta painting, Then I gots ta putting it back together again. I then gots ta making up new front and side panels for it, out of 2mm alloy sheet, That shit came out OK. But then I had to make a bit to fill in the gap behind the dash (as the frame is now longer, and the steering wheel is mounted above rather than below the steering shaft mount bar thing. Did some CAD. Then made a thing. Then decided I would have a crack at welding it on. I've never TIG'd alloy before, but how hard can it be? All my test runs were lovely, but fuck me wrong with a rubber goose, every time I tried to weld the hood, everything would go wrong. It near on drove me insane, but I got there in the end, kinda. I still need to make the under tray, and weld in something to protect the headers, as they are the lowest point, but its bloody close to done. Me and a couple of mates took it out today, on some fast gravel roads, and scared the bejesus out of ourselves. It really needs front brakes though, because it takes a fucking long time to stop on gravel. Its like trying to stop with only a handbrake. It went really well, apart from one or more of the carbs being a bit of a cock, causing the plenum to fill up with gas and flood the engine. Luckily @keltik had a rag and little girly hands, so kindly mopped up the lake of gas through the intake. It was running really rich, which caused it to have a two-stroke like power-band, which made things even more exciting. But yeh, apart from that and a few very minor issues, it went quite well. 19 Quote Link to comment Share on other sites More sharing options...
Popular Post Vintage Grumble Posted February 10, 2020 Author Popular Post Share Posted February 10, 2020 Due to it not running well last outing, I whipped the carbs off, and they were full of sand. Turns out the drain/vent tubes on the carbs must be able to suck? I assume on the motorbike they went to the air box? I think I'll put some pneumatic spec air filter/exhaust/silencer things on there, just to keep shit out. Like this, After cleaning the carbs it was running tumeke again. We took it up to some paddocks in the whops and had a hoon. At the end of the day I drove it back out to the main road (about a 10 min drive at 90kmh) to see what it's like as a daily. Its doing about 7g rpms at 90, which is quite loud, and also my whole left leg went numb/dead, and I couldn't feel the clutch pedal, so not great as a daily. The only issue we had was bashing a bit of a hole in the exhaust (lowest point) which will be an easy fix. Usual shitty vid: 14 Quote Link to comment Share on other sites More sharing options...
Popular Post Vintage Grumble Posted April 4, 2020 Author Popular Post Share Posted April 4, 2020 So Yeh nah, the norgren air filter things didn't work. I took it for a blast on the beach, was probably like 10km away from my car, and it lost all power. The little filter things had got saturated with gas and stopped breathing. Luckily an easy fix, I just cut them off and it ran sweet again. So I thought I'd give plumbing them into the air box a try. I've welded a nipple on the very bottom of the plenum to connect too, this will also act as a drain if a float sticks and floods the plenum again. I also replaced the restricor tape with a bit of flat bar. I also did a dodgy patch on the exhaust, and put some flat bar over it to protect it a bit, as it's the lowest point. I also started building a simple trailer for transporting this thing. It's not going to have springs, and will have a hinged draw bar so it can tilt, so I don't have to have ramps.
