Viper Offroad with full suspension project log.

[xoltri]

Someone on the forums was nice enough to send me some photos of the kart that I believe was made by the designer of the plans. You can see some of the differences and similarities to my kart.

The kart costs more than you'd think. I have over a grand in it so far in parts and materials. The TAV2 ($230 CAD) was the biggest expense followed by the engine ($175 CAD) and tires ($160 CAD). I've tried hard to save money and these are the best deals I could find.

t0x1k, about your chain issues, what size chain did you have? And could it have been a tension issue? I hope I don't have the same problem, I cannot mount my torq-a-verter any other way on this engine.

ZOMG that's exactly now I wanted to setup my future kart!

Except I never thought it'd work (especially the middle suspension lol)

Big update!

I had a big surge of effort in the last day or so and managed to get it almost finished and in drivable condition. Heres the video from youtube, I have some pictures that Ill put up later.

Here are the pictures I promised, showing some of the new construction that I have done. I took some pictures of the throttle and brake linkages as this was one of the areas that I was confused about at first, so maybe it will help someone out.

looks great. I dont think ive ever seen a torque converter in such a crazy position but obviouly it works lol. you should stake out a couse on that field to make it a bit more intresting

Haha, I don't think I'm really supposed to be driving it in the city so that is out of the question.

I've since removed the governor gears and realized that I was only getting 3/4 throttle from the gas pedal, so I adjusted that and it is a lot more powerful now and running great! I plan on mounting a speedometer and once that is done I will take everything off and paint it and put up some more pictures.

i LOVE your kart, and how perfect it is, well done! i was also admiring your keyway. i tried grinding a keyway in my jackshaft, and it was 1% as good as that!

 

[TOO FAST]

[=SMITH=]

[wenceslaore]

Very good work. Your post I am inspired to begin to do my own go-kart, but I am of Argentina, you will have realized by the bad translation, jejeje! And for that reason it is difficult to secure the planes to me of I was looking for them to easykarts.com and I could not find them would thank for much to you if me you could pass the planes in .pdf my mail is wenceslaore@msn.com. I wait for your answer thank you very much. Greetings and very but very good work.

Nicely done !!

 

[down_in_flames]

nicely done! thats one sweet kart

I had a bunch of people over the other day and we really put the kart through its paces. It worked good and everyone had a bunch of fun. But I've inspected the kart and it looks like I have some repairs and modifications to do.

Someone here suggested that I make the lower T arm into an A arm and as it turns out this is a good suggestion. The lower T arms on both sides are noticeably bent backwards due to the hard 40-50kph turns. So I will add another bracket and weld on another support to convert it to an A arm.

I will also have to add support between the two steering uprights because they are starting to spread apart.

All in all it was a good time and I'm glad these problems became apparent with no total failures and in my own backyard so I can make the kart more reliable for when I take it to the lake this summer.

I like your little machine. Anymore vids, maybe on ruff ground ? Show us the new a arms you are making.

 

[xoltri]

I have finished one side of the A-Arm modification. This is the best solution I could think of without having to completely redo everything so I hope that it works well. Give me opinions if you've got 'em. The other side is tack welded and I just have to finish it off.

When the old lower T arms bent back the top T arms were untouched. My only concern now is that since the lower A-Arms are much stronger the upper T arms will be come the weak link and start bending. I guess we'll see.

Also, does anyone know how you can weld the end of tubes closed? I have a bunch of open ends and I don't want the inside of my frame to rust so I would like to weld them shut.

 

[fowler]

fusion weld a plate over the end

 

[theo]

Looks good much better.

I have a strap of 1x1/8" and cut 1x1" pieces then roughly shape on the bench grinder, weld and regrind if needed.
