CAG,CAG,CAG and Oh Yeah CAG! :The Projects Cometh UP

CAM2 — Tue, 06 Dec 2011 03:44:42 GMT

Well you've read the title now meet the projects..............Im gonna do this as a 4 bike build-up so hopefully it doesnt get so confusing following these rebuilds.......

Everythings basically junk to most people and these things are hardly complete........Luckily I have lots of parts stored in totes aswell as daily parts orders arriving..

Most know or seen my 2011 MT-A1 HF trophy cag I won that turned out to be a nitemare.......Ive decided to whip the chinese back at their game and make that weak frame theyve designed for the 2011 model MT-A1 Cag more reliable and stronger by soild filling the frame and forktubes with block fill for car engines and redesigning then building a new stronger upper engine mount

Some also seen shots of my basket case Zenoah powered MT-A1 HF Cag that Ive already started on by modifying it a bit and painting the frame a descent coating of Rustoleum satin black

This one I got yesterday.Its an MT-A2 FF Cag....The kid wanted $40....He got $25 because he painted it like a goofball...............Its gonna take a bit to strip off all the repugnant paint and spray on something a bit better

Got this one tonight.Its a 2006 MT-A2 HF Cag....The kid wanted $90 for this ...lol.....He got $20 and in the picture you can see why..............

Updates to follow soon.........

X7 REPSOL build

darthbeast1983 — Mon, 07 Nov 2011 01:09:00 GMT

ok so i really havent worked on my X18 in a while but we will talk about that later. so when i moved to ohio i had 2 X7's one was a parts expiriment bike, the other just kinda sat there. it ran but i did a head chop and pretty much made a monster out of my yellow x7. so i was bored and completely disassembled the other x7. this is the build. please, ive already make a good 49cc motor. but im hoping cam2 or one of the other resident mad professors will chime in and tell me some more tips and tricks to unlocking even more power out of this thing.">">">">">

X7 goes electricproject

heron — Sat, 15 Oct 2011 03:57:00 GMT

Hi
A while ago i bought an X7 for about 50$, back then it was kind of a wreck. The pull starter was broken, it had no fenders, flat tire, front fork was not bouncing back and the electrical system was a mess.
Now, a few months later, I've fixed most of these things.
It still has no fenders, front light or front blinkers but I'm gonna fix this in a while. The engine runs quite nicely tho and i am able to drive it.

So, why do I post this in the electrical-forum? I am planning to convert it to electric. I've ordered a Turnigy 80-100 7kw motor, controllers and some accessories to make it run.
What's left to get is:

a battery pack
copper wire to rewind the motor (I am planning to run it @ 24v and not 48v as intended)
some wires and connectors
a suitable throttle controller for electric

It is my intention to keep this thread as updated as possible about the project. I don't know how long it'll take to get the parts but hopefully i get them next week or so.
I tried to upload some pics for this post on the forum, but with no success. I would be glad if someone told me how to do, it's more fun with pictures.

Not your average Radio Flyer

RadioFlyerrr — Thu, 30 Jun 2011 18:59:00 GMT

Ok first off I was told to put this thread here by the mods until they found a better place for it. When you do mods, please feel free to relocate :)

So I posted up a pic of one of my current projects when I introduced myself. Many of you wanted to see more so here it is . It is a radio flyer wagon with a custom made full suspension (based of a 32 ford hotrod) chassis with a 110cc 4 speed manual electric start motor.

I will let the pics do most of the talkin.

Start of it all.

Dandy MR-40 Rebuild

nubee420 — Mon, 20 Jun 2011 18:44:00 GMT

I'm starting the rebuild of a Dandy pocket bike I recently picked up for $100...

I tore it down last night and I'll be dropping off a pile of parts hopefully next week to be powder coated. I haven't decided on color yet but I'm leaning towards lime green for the frame & wheels and then either a satin black or flat black finish on the fairings. Any opinions on color would be appreciated.

Nick's Water cooled bikes.... MT-A4 ( C1 )

NaSa — Sun, 19 Jun 2011 23:41:00 GMT

Whats up guys, so I found some older pictures of my bikes when I first got started, haha obviously paint was more important to me back then.... the over-spray was cleaned up at one point...

Let me know what you guys think, It was a "Goonies" theme, now it's just the old tore up Konica Minolta <--not gonna post a pic it's UGLY from sitting outside for a year!

L7 Ducati project

xlilpimpstab0ix — Sat, 11 Jun 2011 20:26:41 GMT

Finally! I'm actually almost done building this bike. It started of as a bare frame from one of the members of this. I think his name was juanitoboy or something. Anywho, I have a Lucky 7. The frame is painted red. White wheels are on it's way. I'm actually debating if I should go polished wheels or white. Maybe you guys could help me out with that. I have sams BB kit I think the stage 3 package that he offered, a jet pro pipe from ebay, x7 forks/trees, x7 wheel spacers, cat-eye handle bars, pro jet pipe and a walbro carb from randy @ ********parts4less. What else does this thing need? I also need your guy's help with chain tensioners in the rear. Right now I have cut washers but I don't think they'll do justice. Any ideas on what I could use. instead? Maybe something rectangular and thick? I'm also in a search for the brake bracket for the rear as well. It's pretty hard to find. :rolleyes::thumbsup:

May/June Bike of the Month

SpyGuy — Tue, 31 May 2011 06:59:00 GMT

Okay, it kinda looks like we're doing this contest bi-monthly, since the March BOTM took so long .... Here's the score: during the entire month of May, you may post your bike for the contest (one entry per person, please). The voting will begin June 1st through June 25th. After June 25th, the winning bike will be posted for several days on the thread (and maybe if you sweet-talk Nick, he'll make up some cool picture with your bike in it or something for your signature). Remember, no PhotoShopping, just several good pics of your ride. Collages of various shots are welcome.

Put 'em up, guys - show us what you got!

x18 Marlboro Ducati build

Low Side — Tue, 24 May 2011 18:09:00 GMT

So this is the bike I started off with, it was a good price and the motor was OK. (green X18)

I used an X7 tail from my old bike, and custom fit it to the stock one on the x18. I also used the side faring where your leg rest and fiberglassed everything together into one. It took a while and alot of bondo work.

At this time there was no pipe.. I had just painted the rims black, bondo'd and primed the tank and new custom tail. There are also no elecs. I had to wait for all the parts.

Custom intake I installed, a little bit bigger then the PBU one. barely any clearance for one any larger.

I finally got the side farings on, and put on the custom pipe i'm currently waiting to wrap.

Road_Clams X18 thread

Road_Clam — Tue, 12 Apr 2011 21:19:00 GMT

Well I think I will start a thread on my X18 starting from the day I pulled it out of the crate. Uncrating was fairly easy and straight foreward. Now the fun begins. First I gave the bike a thourough assesment of assembled "quality" and like so many of you comment, it was pathetic at best !
Right off the bat i'm finding cross threaded body mount screws, plastic components that were barely "snug" .

Next moving on to getting it started. I know many of you suggested swapping the oil, but for my initial quick break IMO. the std oil is fine. I'll put a few easy hrs on the engine, then dump the OEM stuff . Initially my X18 would start no problem but would not idle. So after searching I found the idle screw, and after about 2 turns, now we're good I have an idle. My engine has a slight surge to the idle, and i'm thinking the carb is jetted "EPA" lean, so I might open the carb up and see what the jets look like. Right now the first step is to put the engine through a few "heat cycles" I believe heat cycling the engine tempers the internal components for longer life. People will argue this comment, but i've been doing this for many years with excellent engine relibility following new or rebuilt running. Here's a few pics for those of you that didn't follow my "pulled trigger" thread;

Cutting Stencils and Tape really is boring... UPDATE

DJ_Critterus — Fri, 25 Mar 2011 19:46:00 GMT

Like I said in the title, it really is boring and tedious. It's my least favorite part of the process. Sanding comes in a distant second to this.

So, I got a sticker meant to go over a car's tail lights. It's a flexible plastic that's not too flimsy.

I was going to cut this, but I got to looking and found the backing had imprint marks from when the decal was made. Hmm... I have a mo'betterer idea. So, I got out the exacto knife and went to cutting. Not bad. I ended up laying down my blue tape on the body pieces and held the stencil in place as I went over it with a marker.

And here's the general idea of what I'm going for. This design will be painted in red and then the whole thing will be covered in a clear coat with high metallic content.

Now, to get back to playing with sharp objects while my wife is out shopping with her friends.......

New Engine Finished

jaloos — Fri, 18 Feb 2011 09:32:00 GMT

Picked up a new motor and decided to mod it up a bit before I dropped it into the bike. There was an issue with the air filter I had to deal with as well so figured I would do what I could to it.
I am assuming its a 39cc sold as 49cc engine as the bottom 4 fins are present (dam LOL). Oh well bag it out then do a crank and head kit.
The front of the carb was taper bored from 19mm down to 12.3mm at the slide. Note the notch removed from the choke plate to accomodate the new opening size. The rear was bored to 16.48mm. In both cases leaving the slide area alone. I added the boost bottle tap to the back of the carb as well. The petcock mod was done with belzona ceramic epoxy, drilled through and oil sanded smooth. The float and float bowl were polished and deburred to avoid hangup and a 70 main jet installed. I matched the intake to the rear of the carb. I then filled the shallows of the intake with belzona ceramic epoxy and oil sanded it smooth and flush as the sealing surface around the hole was very thin now. Behind that is carbon reeds with the tripple stage mod done with the original reed and ground down reed stops. On the inlet to the carb i modded the cheap plastic ufo filter mount to a offset v-stack stye by making a paper mold, pouring it full of liquid epoxy and filing and sanding followed up with the mod to the air filter to clear the cross brace on this frame. I used the 6 fin lightened flywheel I did and added an aluminum pull start that I widened the notch for the wire out and epoxied a section of slit hose to protect the wires from getting messed up. The plug wire and boot were also replaced. I plan on fitting the modded stock exhaust to it and see how it works out. A three bearing 7 tooth is supposedly on its way for it (dam HKMoto LOL)

I am not expecting anything to great out of it till I crap it out but at least everything will be ready for a fc crank and a boosted head kit LOL.

The Rat - SpyGuy's Redneck-Style Cagllari/Daytona

SpyGuy — Wed, 24 Nov 2010 05:51:45 GMT

"The Rat" (a work in progress)

Background: The Rat originally started off as a stock half-fairing 47cc Cagllari/Daytona. Purchased on craigslist.com for $80.00, previous owner had apparently used the bike as an offroad dirt bike. Front fairing was missing, seat and tank section was cracked in half behind tank and at end of seat - entire rear section missing. So begins the tale of "The Rat-Cag"......

I decided when I bought this bike that I was not going to restore it to original condition. Instead, the plan was to play with it, see what fun and goofy things I could modify on the bike, yet still have a perfectly functional bike to ride. Below is a list of the modifications currently on this bike, with more to come. *** NOTE: this is NOT meant to be a serious race bike - this bike was built "redneck-style" for fun.**

SPECIFICATIONS AND MODIFICATIONS:
Gas Tank:
Hard-mounted to frame with brackets. Gas cap has been modified with a breather filter made from an in-tank gas filter. Gas tank was originally hard-mounted to frame using a hose clamp, which is visible in earlier pictures of the bike.
Seat:
Seat is glued down on piece of sheet metal, cut to fit shape of seat. Seat is supported by section of cut-down office keyboard track, and bolted to frame using the original holes.
Air cleaner:
Air cleaner is an Altoids Chocolate-Covered Cinnamon Mints box. The box has been drilled multiple times to allow air flow, and a piece of window screen wrapped in pantyhose protects the carburetor venturi. Oh, and the red gasket in the picture is from a toilet tank. (A second air cleaner, not on the bike, is made from an electric socket junction box.)
Gas filter:
A cut-down Volkswagon gasoline filter makes sure that the carburetor stays clean.
Muffler/exhaust:
An empty DuPont paint spraycan was modified for the exhaust by cutting off the bottom of the can. Tinsnips were used to enlarge the opening on the top of the can to fit over the front ring of the stock muffler, while the bottom of the can was cut to accept the stock muffler end cap. It is held on by the original spring and cotter pin.
Footpegs:
Footpegs are Mongoose BMX stunt pegs mounted on tapped original studs. This was a previous owner modification.
MISCELLANEOUS FEATURES:
Dremel wrench killswitch cover: A spare wrench was bent and screwed down under the original-style killswitch, so I wouldn't accidentally bump it while riding.
