This is my thread on my minibike rebuild. I found out its a 1970 Rupp Roadster. Its apparently worth something so I'm going to restore it. I'm hoping in the end I can look as cool as Jim Carey in Dumb and Dumber. :?: Here's how I found it in a field:

Its current condition:

This thing's got a pretty cool torque converter setup on it. Its kinda like a lockup clutch:

I wetsanded the outside cover and scraped the stickers. Mother's Back to Black is fucking awesome for getting black plastic to look good again. Before:

Just started getting into the motor. Nothing too exciting but I don't think these 4hp Tecumseh like boost or any performance parts from what I hear. :-\ I hoping when its all done I can sell it to RickP. :?: That is all.

Thats gonna be one fine hog when you're done.

I'm going to take it over some sweet jumps
-
in for this. i have a feeling its going to be awesome
-
Right on, take some of that rust off and it will look alot better.
-
Take the seat off and I'll try to pick it up tomorrow.
-
Turbo it.
-
Thats gonna clean up nice! :o
-
Should I keep the original colors? I'm not getting anything chromed so chances are they are going to be black. The original frame color is Chevy hugger orange. What do you think?
-
Id say if youre rebuilding it for resale value to keep the same colors.
Turbo it.
Seconded. Do it.
-
Id keep the OEM colors.
-
Save the stickers too if at all possible. Collectors go apeshit for original stickers.
-
Turbo it.
Seconded. Do it.
**pulls turbo out of inventory**
this would work :D

I heard these motors don't take shit for power and this motor is apparently valueable. Looks like your normal lawn mower motor to me :-\

that thing is tits :)

Update: Since it doesn't run, chrome it. O0 I was originally just going to paint all the chrome parts but I gave it a shot to polish them up:
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fimg.photobucket.com%2Falbums%2Fv450%2FHMTWhitey%2FMinibike%2FDSC01355.jpg&hash=f51c099957a067b92c2a4695c0a0a4c3b12d9b6c)
Some simple green, rubbing compound and chrome polish you get:

I fucked up and first tried to get all the rust off with a green pad and now its all faded. >:( Anyone know if I can fix the scratches now in the chrome? I tried rubbing compound and no luck. You can see the difference in the finish between the two. Luckily I only fucked up the back fender:

As you can see they are not perfect but I think good enough not to paint. Here's where we sit today:

There might be a big payday at the end of all this. :noel: I got excited after watching some ebay auctions
$710.00 and its the shittier model:

:yes:

back to black really does work good
-
Sweet find. Looks like theres a lot of shit there, is it on the property of someone you know or were you just hiking or..?
Best find a certain member on here found and shared the location with me years ago was a mostly complete civic hatch but I of course couldn't take it home :P
-
Just a little update its all ripped apart and getting ready for paint and a rebuild on the motor:

I'm looking into trying to make it street legal. Than I can race people on their faggy Honda Ruckus' :yes:
-
Ruckii are ghey sauce.
-
Find a bumper resto company and see if they can do anything with those fenders. I think those fenders have more shine to come out of them. You try some good ole never dull? $3 a can at walmart.
-
pretty sure a torque coverter uses fluid to transfer the power to action...that is a centrifugal clutch, found on most small engines...if it is actually worth it to redo that motor and keep it as a collector's item, go for it...otherwise, i'd find something bigger to slap in that thing. Those minibikes/trailbikes are fuckin sweet trail riding, just not super fast O0
-
They used to call CVT's torque converters back in the day. Now known as Constantly Variable Transmission. There are all kinds of things you can do to tune the shift rates, look up snowmobile clutches.

My Ruckus will rape your Rupp in the ass... right after I finish wiring the Megasquirt. :noel:
Nice project, chief.
-
you going to sandblast and bondo everything before paint?
-
That chrome came out really well. Considering what ebay has em going for, it might be worth it to get em dipped.
-
So are you going to repaint it orange?
-
Cool free shit and it even looks like a fun project.
hugger orange is a great colour, i'd stick to it, and if you're not selling it right away, get a 10$ B$S motor and turbo that for a while...., 1v draw through style!!
-

Everything is getting sandblasted. If the metal is really pitted I will bondo but I'm hoping to use some high build primer to cover everything up. I'm new to bodywork so I'm still doing research on what to buy/do. So I've been avoiding sandblasting any parts that are going to get painted until I bough all the supplies. Right now I'm just cleaning up motor parts:

What these things go for is way too random. Some go for $800 unrestored and virtually the same bike will go for $200 the next week. ??? I don't think I'll get my money back if I chrome the parts so I think they look good enough but I still think I can get them better.
So are you going to repaint it orange?
I'd like to but I'm having trouble finding it. I'm looking at Duplicolor's stuff (aerosol) but all the local stores don't have the original orange. I'm going to try and keep all original colors except the wheels and handlebars are probably going black and the front forks are going silver. These are all chrome parts that are too far gone to restore the original chrome.
if you're not selling it right away, get a 10$ B$S motor and turbo that for a while...., 1v draw through style!!
I have another frame and motor that I might do it on. I got the fever to do another minibike. A turbo one with one of those Heineken mini kegs for a gas tank would be cool. :yes:

it looks like a 3hp tecumseh motor based on that flywheel
Its an HS40. 4hp of fury

Anyone know how to do bodywork? ??? There's some bad pitting in some spots. Would some high build primer fix these spots or do I need to bondo? :?:
Also, street legal Rupp on Ebay but it now $1900:

yeah, gouge that area out with a grinder, and bondo that sucker up, and sand smooth. then hit it with self etching primer. self etching will bond to the metal better.

that thing is gonna be sweet as hell when its done

killer build so far
-
i tried building up with some primer once, and it didn't tur out to well. i would definatley suggest the bondo if you want it to turn out right. body work takes patience
-
I would probably cover the entire thing with bondo and sand the entire thing. And dont go to walmart and get the "bondo" brand. Go get some good 3m stuff from napa.

Just a little update, painting process has begun. Went and bought some paint:

For the chrome fenders, you'll have to put some serious elbow grease into them. Start sanding. Start off with 800 or 1000 grit and work your way to the finest grit you can find. Then polish it using various stage polishing compound/liquids. It'll turn out like glass. :yes:
Sweet project.
-
Wow. What a difference. Shit is starting to look good!
-
Progress has been slow on this thing but I'm getting my act together to finish it. I finally got the wheels disassembled, sandblasted and painted. The drum brakes were siezed together becuase of all the rust and was a fucking pain in the ass to separate. I didn't dismount the tires so its like a Macco job where they paint your tires for free:
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fimg.photobucket.com%2Falbums%2Fv450%2FHMTWhitey%2FMinibike%2FDSC01473.jpg&hash=d9b24448b0d722ce930071d9cc3473b6341ac439)
I finally honed the cylinder. I was debating on weather to paint the motor black or leave it bare metal like the original. I figured if I didn't do anything it would eventually look like shit so I ended up using steel wool, polishing compound, acetone than finally painting the block with clear engine enamel. I think it turned out ok. I just now need to get all the nuts and bolts for it so I can assemble the motor. Probably going to use socket head cap screws for everytihing:
