Yes, very interested!!

[Bashan]

Well I mounted the manifold riser from Buggy Parts NW, it's a really nice piece, no rough edges or burrs:

You can see how much bigger it is than the standard intake port:

Then I mounted the performance manifold from Scrappy on top of the riser:

And of course, as usual, my carb will not fit between the manifold and engine mount:

I don't think this is anybody's fault other than the boneheads that made my scooter with a bizarro engine mount. So I turned the manifold around pointing forward!:

Then I got some strong radiator hose that had a couple bends in it from Auto Zone and used my bandsaw to make a manifold hose. Then I hooked the carb to it:

Here's a top view, you can see the manifold hose better:

Here's a few more pics, I haven't had much of a chance to try it out yet but so far it's been really strong with a 115 jet. Yes, I'm running without a cooling shroud, I figure with no body plastic and the cooler air I should be OK. I'll let you know later how the test runs come out. Rich

Nice work! I wonder if they really need the forced air cooling when the engine is out in the open. You could remove the cooling fan and gain a little HP too.

[Bashan]

Great idea, when I read that I just smacked my head and said "DUH!" It's obviously serving no purpose without the shroud. I won't get a chance to try it out until this afternoon or maybe Thursday. I think the engine looks cool like that, more mechanical. Thanks for the tip. Rich

Rich,

This thing jus' gets gooder and gooder... LOL!

I've been cogitatin' on the pix, and REALLY like the whole skeletonized approach. Since MOST of the external cosmetics are now history anyway, how about chopping off everything south of the shock mounts, including the fuel tank... THEN, adding a barrel-style fuel tank right behind the new seat (easy project from a small aluminum beer keg, or a round tank from vintage stationary engine)?

For rear lighting, bobber-style tail and stop lights (Model A Ford lights are GREAT) and little "bullet" lights for turn signals. Oh yes, and the obligatory vertical license plate...

I know... I'm full of ideas for other guys rides... LOL! Just ignore anything you don't like... But this one is fast becoming a scooter version of a classic bobber! My kind of bike, whether a harley, Brit twin... Or a scooter!

Just some ideas to further reduce the parts count and increase the bad-rat factor...

Love it!

PS: Makes me wish I had the time and bucks to buld a "hooligan scoot" of my own! Yours may make the pinup boards in the nastiest scooter bars of Europe! Now THAT'S the real deal!

[jhbietz]

Got this of EBay for my naked scooter project. Payed $1.25 plus $17.00 shipping. LOL should allow me to remove all the plastic around the handle bars. The spedo uses some kind of magnetic pick up so that is going to take a little engineering to make work or I can get a standard cable Drive spedo and use the other 2 gauges and the nice mounts.

Thanks for the great ideas guys, I do plan on moving the gas tank and the keg sounds tasty. I'm definately going to need an instrument cluster as you will see.

First off, I got busted.....kinda. I was bragging in another post about how I never turned on my bucket light because it sucked too much juice. Turns out a certain trooper wasn't too wild about that idea, and some of my other "innovations".

So first off I went down to Auto Weinie and picked up an LED accent light. He told me that technically it should be a headlight but as long as I had something lit on the front during the day, the cops wouldn't bother me. So here's what I ended up with:

Switch off.........................................................................Switch on.


Real eyeball burner eh? I guess as long as they're happy its fine by me. He also was nice enough to tell me that front fenders were not "mandantory" on motorcycles but if I wanted a rock to fly up and hit me in the face, that was my business. Er, thanks officer.......I think. Anyway, I gleefully lost the front fender:

You may have noticed I got rid of the small seat too, my 58 year old bum couldn't take it anymore. So I switched it with the other seat I wasn't using off of my Vulcan, the rider's seat. This mounted to the motorcycle with a ring that fit in a slot on the seat. So I mounted the unused ring (the Mustang Seat doesn't use it) and bolted it to the front frame horn. The slot on the seat slips over it:

I think it has a nice, if slightly unbalanced, look:

He also told me that they didn't like batteries hanging down unprotected below the frame. So I described the following to him and he thought it would be just dandy:

Yes those are zip ties and no its not in the way.

He wasn't wild about the carburetor sticking out between my legs either.....something about a fire hazard blah blah blah. Actually, I was thinking I'm sick of the bowl going dry from being shaken around from such a lofty perch. So I promised him I'd move it back down to the engine and I do as I promise. I used the performance chrome manifold finally. Note the Briggs & Stratton fuel valve, I highly recommend them, great flow and easy to turn:

I just had to take about an 1/8" off of the motor mount somewhere down in here with a file to make room for the carb:

I got a Tiny Tach so I could monitor the RPMs. They couldn't be easier to install, you wrap one wire around your spark plug and ground the other one:

Here's the read out next to my GPS/Speedometer, note the expensive mount:

A word about my electricals. I had to reposition them to make room for everything else. To the left of the blue dot is the solenoid with the top pointed at the camera. The green dot is the rectifier, and then there's a bunch of pretty, colorful wires running EVERYWHERE! Sorry, I got carried away.

I did take Mflorek's advice and upgraded my coil connectors, I suggest you do so also, it helped.

Last but not least, I went through three different strap configurations on my stainless exhaust only to find them gone when I got home. So I got serious with this mechano-nightmare:

It hasn't budged a mm! I guessed at a 122.5 jet and I've only had it down the block. Seemed very strong, at least it started, that's a good sign. I'll give it some GPS runs this afternoon, with my light ON! Rich

[oldchopperguy]

Rich,

Sounds like you ran into "Barney Fife"... LOL! At least he was more helpful than painful. As for no front fender, I rode fenderless choppers for about 40 years. Never did have a problem with rocks in the pie-hole, but there WAS this one skunk... Whew! Or should I say "PEW!"?

Lookin' pretty speedy! If she goes like she looks, you're gonna have fun!

Ride safe,

That sure looks like a mover. The only thing is that where the battery is it distracts from the scalped look of the speedster. Maybe a Army Ammo Box would fit the bill, make some slots in it for air and then mount the box where it was berfore. The Ammo box is very strong and has a very nice lid with a snap down latch. Paint is black and it would look custom and the local enforcement people then cannot say its not protected.

Hmmm...

ALL of us must have griped about the problems with carb mounting... The air-filter gets in the way, the frames just don't allow much creativity... etc. Has anyone ever considered making a REMOTE FLOAT BOWL?

If that could be done, the carb could then be mounted "down-draft" style, or in most any position.

For that matter, has anyone tried using a diaphragm "pumper" carb as used on 2-stroke go karts, chainsaws, etc. as well as Harley-Davidson and some other 4-strokes. This would also allow mounting the carb any way that's convenient.

Just wondering, as this phenomenon seems to be a real issue, even when simply improving the filter on bone-stock engines.

Any trick that would make carb-mounting and modification easier would be welcome for sure!

PS: Hey Alleyoop... Just noticed you're in Westmont! While I've been in Texas since dirt was invented... I was born in Hinsdale, grew up in LaGrange Park, worked for years in Oak Brook and Downers Grove... So, I'm mighty familiar with your stomping grounds! You can surely use those trikes in the winter!

[Bashan]

Both of you guys are reading my mind! What's left to read anyway . I've GOT to move the battery, it's not in the way amazingly enough it just looks like crap; I'm still brainstorming over it. I set out to just have an experimental scooter to try things out and post them on the site. Now it's my favorite scooter and I usually take it rather than the Motorino. It's kind of famous around Chelsea, AL, people recognize it and wave and do a thumbs up...very cool.

LEO! I can't tell you how many hours I've spent online looking for a downdraft carb, I can't find any for four stroke. So you think a 2T carb would work? I've been trying to devise a way to have the bowl hang on the side of the carb but keep running into a mental brick wall. A downdraft would shoot right down into the head, better performance I think and definately easier to work on. Steven at MonsterGY6 found these gas tanks for me, I think I'm going to get one:

Rich,

Being an old kart guy from the sixties, I've run a LOT of diaphragm carbs. Most of the kart carbs are too small for these engines, but the bigger McCulloch kart motors did use a VERY large one! Maybe even TOO large! My problem is that I've never run one on a 4-stroke. The 2-strokes use crankcase pulsations to operate the diaphragm.

However, many later Harleys use pumper carbs. You could probably find out how they are activated on a 4-cycle engine, from a shop. I would think however, that one could remove the float bowl assembly from a GY6 carb with a small disk-grinder, then, re-build it and re-locate it and re-plumb it to the carb body. Remote float bowls were not uncommon in the old days.

You might even use a scrap carb to donate the float bowl, then plumb it remotely into the carb on the engine, bypassing the float on that carb. Heck, all they are is a teensy toilet tank... LOL!

I'm still thinking the pumper-carb may be final answer. Wish I had experience with them on 4-cycles. Seems they would have to have the diaphragm working, to prevent fuel just running through the carb. I'd speak with a Harley dealer, or a custom shop. There must be a way...

VERY cool keg tank!!!

Wish I could be of more help. Somebody out there must me expert with pumper-carbs on 4-strokes!

Ride safe,

Leo

Well I do ride in the winter but ONLY if the streets are dry

What a coincedence!! I used to live in texas when I was 4 years old. My Dad was a Foreman at the "YO" ranch! I used to go on roundups with the cowpokes in the summer when I was on summer vacation I was around 10 years old. I also went with them hunting down Wildboar cause they were killing a lot of sheep and goats. I used to carry a 22 rifle(HAHA) not that it would do squat to a Boar. They were mean suckers, we would corral one in the bushes and they would attack the horses so you had better be hanging on(at least me) or you would get thrown off when the horse would rear back on you.

I can also say they have some BIG RATTELRS there. One night we were up north and one of the horses went to drink at the Trough and a HUGE rattler was right next to it and bit him on the side of his head. The horse fell almost right away we got our lanterns and saw where it crawled into and we got it. The Head was as big as a grown mans hand and it was about 4-5 inches in diameter. I had never seen a rattler that big. We hung it from the top of the fence it must have been 5-6 feet long.

I found this while Googling around, I'm not sure what this first one is, it seems kinda flakey:

Yeah, those rattlers DO get "Texas-size"... I live in a God-forsaken trailer-house, and underneath are a regular population of rattlers, copperheads and cotton-mouths. They are just "there" and don't want to leave, so I leave them alone and they seem happy to reciprocate!

Our opposite paths in life really ARE a coincedence! Be careful in those Chicago winters!

Ride safe,
