Yeah, that kinda pissed me off. I was new to jetting and thought I might need it by the way the web site talked. It was only $5.00 but it was a rip. I don't know if would even work with a 30mm carb, four valve head, and performance exhaust. I tries to use it (of course) and it was ridiculous, turned the plug oily black in a heartbeat. Rich.
Well couple problems with a 30mm carb verses the 24mm it comes with. 1. The 30mm Carb the intake is 30mm but your Head Intake is only 24mm!! So its actually worse cause now the air and fuel is restricted and not flowing smooth into the intake because the the Carb opening is bigger in diameter than your Head Intake. 2. Replacing a 24 with a The 30mm Carb you already know its going to pump a lot of more fuel stock than the 24mm. So if nothing else is done it will pump to much fuel and flood the damn thing. Alleyoop
Well here's the continuing saga, I developed a bad front end shake that I could just not isolate where it was coming from, so I stripped off all of the plastic and bolted the headlights to the horn bracket. It came out rather bizarre:
Passenger footpegs from Vulcan find new use as scooter foot rest:
Then I got to thinking that the "man" might not like it without a fender so I put that back on:
And now I'm struggling to put the new stainless exhaust on, the bracket won't quite fit, I'm going to have to get longer bolts and sleeve spacers at lowes tomorrow:
The new system should look nice on the scoot though:
I ordered some exhaust gaskets from Buggy Parts NW along with some other stuff so I guess I'm on hold till that gets here.......Bummer. Rich
Well, I got the exhaust on now, it has a wonderful throaty tone, not obnoxious at all. Much faster too with the less resistance. It doesn't seem to be running lean but I haven't pulled a plug yet. I did get a new headlight on. Here's some pics, what do you think of the new light? The BUG is dead! Rich:
New Stainless exhaust:
Now I've got a no rev limit purple CDI and an iridium plug to put on. I've got a few other thigs up my sleeve that y'all will think I'm crazy for planning. Stay tuned! Rich
So Bashan,, do you still have the 115 main jet in there ?. Were you satisfied with the 115 after you removed the airbox and put on the Uni ? I still have the 125 in mine. (removed airbox and put on a Uni)Seems to use a lot of gas although the spark plug is more white than brown.. Boy, you have really done the number on that scoot !!! Should run like a striped ape.. Harv.
It does run great now. I just now got back from a ride after I installed the purple no rev limitier CDI from Mike at Buggy Parts NW. It also came with an iridium plug. I took it out and it sounds like a cruiser MC with that stainless exhaust. The no rev CDI does as promised, no limit. I think I hit about 62 before shutting it down for the turn into our development, It'll pull a wheelie now no problem. I passed a car for the first time today......blew by him! I had to mount the CDI low due to seat issues.Here's some pics of the CDI: The old one is little compared to it:
One other update, I removed the ignition switch. A toggle swithch connectects the red and black wires together like the key does so you can start it, and a button does the killground as the key would when you shut it off. I guess somebody could steal it now if they could figure the switches out, The one in the middle turns on the DC headlight.
Next I start on mods to the CVT, I'm going tp pull the flywheel so I can write up a tutortial on stator duagnostics and replacement, and a complete rewire with buses so everything has a logical place to plug in. Rich

As the "old chopper guy" I'm really liking what you've done... This is the essence of what we did "back in the day" like in the early sixties... when chopping a Harley or Brit bike. OR a Cushman...
The high-mounted single headlight is classic. How about a suggestion here? A simple fabrication of a false (cosmetic only) top triple-tree from sheet stock, and false upper fork downtube extensions from chrome sink-pipe or polished aluminum tube, running from the top end of the real downtubes to the fake top triple-tree? That would closely simulate a Cushman Eagle front fork, and be in character with the new headlight.
Either no front fender, or, a simple one like the red-painted rear would also be in character (bet you could find a perfect trailer fender at Northern Tool of similar place) creating a great fifties old-school cosmetic to the front end without any real alterations. Simple, clean and WAY different from the typical "short fork" look of the original.
Great looking upsweep exhaust too, now, if you could only snag a sprung solo seat!
No hard feelings if you don't like these ideas, just me rambling... but I'm hard-core, rat-rod, rat-bike, bobber/chopper old-school, and your scoot is quickly heading toward just what I'd build if I had the extra time and money...
I'm AMAZED at how a Chinese design can edge toward a fifties American "bobber"!
Harv, I've been back and forth between 115 and 125 so many times I could do it in my sleep! I just can't quite get it dialed in. I did take Alleyoop's advice (always a good idea) and have been pushing the rich side because my pipe was turning blue (=too lean). I've ordered a 120 and 122.5 from MonsterGY6 along with the pack #2 CVT upgrade so maybe one of those jets is the answer; scooters....always an adventure.
Leo, I love suggestions, never any offense taken. I would LOVE a new seat just like you said, but where on Earth do you find something like that? I think it would be cool if the back half of the engine bay was visible from the top with just a front seat, I'll keep looking. I have been thinking about the triple too, you can tell we're a couple old bikers . How about this, the springer look? Now THAT would be cul! Again, finding even a fake one would be a chore, but I'll run into something. Yeah, I gotta do something with the fenders, they look goofy like that. I was going to just go without one on the front but I'm afraid of inviting a traffic stop....would NOT be fun. I'll post something on the CVT upgrade after it gets here. Rich
I forgot to tell you guys, I rode it like I stole it one day about a week ago. Buried the needle which is 75, but I have to subtract 15 so it was something over 60.; it'll do that now with the purple no rev limit CDI. Anyway, I was just blowing off some steam thinking "go ahead and shake you S.O.B." and suddenly it smoothed out quite a bit, about 80% I'd guess. I get home and I'm looking it over trying to figure out what happened and I notice three of the six little square balancing weights fell off from when I got the tire replaced that Green Earth Scooters wouldn't make good on. So now I'm not sure if taking more weights off would help or make it worse. The frame IS off some but that definately helped. I call it the X-DOC.....definately experimental. Rich

That hog springer is definitely cool! They don't drive all that great though, and making one up for a scooter could be a LOT of work. What I was thinking would just involve two cosmetic downtube "tops" from the end of the real fork tubes, up to a fake top triple-tree made from sheet stock. Just for looks, but would simulate a traditional full-length cycle-type fork. Only a cosmetic fake, but would look "period"...
GOOD NEWS for seeking a solo seat! They appear on eBay quite often, in all sizes and shapes, from the super-wide old Harley style, down to skinny chopper types, and everything inbetween. They can be EXPENSIVE but often they appear for less than $50. Some I've seen go for a $20 bid plus shipping! You just have to look until you find a bargain. I'm not sure you couldn't even use a quality sprung bicycle saddle. They're a LOT like the old Italian scooter seats. Probably were also used on some European bicycles!
Glad to hear the wobble is improved and the scoot is fast! I do believe we sorta like the same style rides!
I'm about to move on to the next engine mod. I've been trying to get the airflow right and I just can't quite get dialed in. I've been through several experimental air hoses and settled on this one with a 115 jet:
I talked with Mike at Buggy Parts NW (a very nice and knowledgeable gentleman) and he suggested I go with the manifold riser and a true "Uni filter" So I ordered them from him and, with the chrome manifold I still have from Scrappy, I should be able to put an intake system together.Here's the chrome manifold and the stuff I got from Mike:
Mike says it's been his experience that 150cc GY6s like about six inches of airflow before the head; that's why a velocity stack of some kind helps so much. I experienced that myself when I put on an air hose extension; the engine ran much stronger. So with what I'm about to do, the riser, manifold, and Uni should give me around the six inches of airflow. Also, the carb will actually be ABOVE the engine mount. I think it will be a nice clean look and make it much easier to switch jets when I want to.
Not to bore you, but I want to post a few pictures of X-Bash as he is before he loses a little more plastic. Oh hey, I put a different seat on too! It's the old passenger seat from my Vulcan, I put a Mustang on it and had this one sitting around. Might as well put it to use!:
Here's the Tom Tom GPS I use so I can actually know how fast I'm going, I'm hitting 60 with the CVT upgrade I did from Monster GY6:
