So what I want to tell you is DO NOT MOD your scooter! I was SO pissed at myself. It ran totally perfect before. All I really wanted was quicker acceleration and I could have totally taken care of that with rollers, springs and clutch... a great lesson for all the newbies. altering the jet size is a little more complicated than simply replacing the old with the new. i don't recommend it at all unless you plan on getting a big bore rebuild kit. Good advice for a Newbie. The Kids credibility wen right out the window as soon as he stated he tried to Mod the Stock Exhaust. that amounts to Hacking its Guts out, if he had a Clue he would have noticed the Exhaust Port is Larger than the Head Pipe. She's farting thru a Straw, Hacking the Stock Exhaust guts out and using the Stock Head Pipe would accomplish one thing, he turned it into a Noise maker. Then when it came to jetting he had no clue what he was doing, Just a Barn Yard Butcher.. The CVK Carb is extremely forgiving and Easy to tune, you can make fairly drastic changes and she will still go down the road. It just doesn't get any easier than working on a GY-6 150cc scoot with a CVK carb. Thousands of us have very successfully installed a Free Flow Exhaust and Uni Air Filter with jetting changes with No issues. If one does a Free Flow Exhaust with a Un-Filter Jetting is Required. This kid should have to take a aptitude test and get a license to purchase tools. Hes in No position to be giving others advice of any kind. |

 Chopper dude this is the extent a "Chamber" is used in motorsports anywhere in the World, a Resonant Chamber, this is from Pipe God Mr Peyton at Pro-Circuit racing, Mr Peyton, Mr Emler ,Bill have spent thousands f hours in Dyno rooms.over the past 50 years or more. Your Stinger is like you Farting thru a Cocktail straw, it does create adverse back pressure for the GY-6 that like a HD loves to breath. You would be laughed out of the office of any of the Gods of Pipes showing them the 2-T pipe on your GY-6 150, thats your prerogative. I had and have had no ill will towards you that there is a hatchet to bury, Its all good and I would sit down and have a beer with you at Willhoits. There is no way you could know I served on a jury back in  of the Gangster who killed the little girl on Juneteenth in Stop-six, a apology was not necessary,but accepted. Im moving forward and finished here. Cheers |

I stand corrected. They still have No insurance as they have No License to have Revoked. Meth Heads, Heroin Heads and Drunks. they are Not at all judgemental when it comes to people who ride scooters in NC? Thank you very much. I ride a scooter because I choose to. Yes, I have a valid NC drivers license, and insurance. Not all scooter riders are Meth heads, heroin heads and drunks. That would be like me saying that all men are a-holes. Oh jeez, all offended and your panties in a wad, I own and ride a 150cc Scooter for pleaser and hobby and Im not a Doowie offender or heroin head. Ive had a MC endorsement for 41 years Ive lived in NC for 3 years and 7 months and have yet to see a 49cc Scooter owner in Randolph county that hasn't lost his license due to multiple offenses, It still get cold down here and the Saps are out on them in the winter with there Carharts on in the freezing rain not because they love riding because they have lost there license, there Scooters are also the worst maintained vehicles on the road. I would bet you couldn't show me close to 1% of 49cc owners in NC that there only mode of transportation is a 49cc scoot because they choose too. It is what it is, deal with it....... Peddle Faster those are Banjos you hear. |

as a guy who sells tires (as well as automotive services), for a living, I say a resounding DON'T DO IT! If it's an absolute last resort just to limp to the shop to get a new hoop, you might be ok, but it's never a permanent fix on a motorcycle (including scooters), unless you have a car tire on the back, which is in itself another issue entirely. Here's the reason: when it comes to car tires, one should never, ever put a plug in the shoulder of the tire. When plugging a tire, you should only do so in the area between the shoulders and no closer to the shoulder than about a thumb's width. the shoulder is where the sidewall and tread surface meet as well as where the cords inside transition from going bead to bead, to having a top layer going around the circumference of the tire. Since the sidewall is where your suspension pretty much starts and it is bearing the weight of the vehicle and passengers, compromising the connecting area between the sidewall and treadsurface (the shoulder), is unwise. Transitioning back to motorcycles, the tread surface on motorcycle tires is pretty much all shoulder since they don't have a flat area on the tread surface. that being the case, there really is no safe place to plug or patch these tires. Well sure from a sales point or a large national retailer of tires like National Tire and Battery or Discount tire your in business to Sell tires, there very little money to be made plunging tires and if ya tried to slap a minimum labor fee on it customers would complain it costs to much. I would also venture to say those large retailers have a store policy Not to Plug tires, probably some Liability issues come up, even if a customer pleads to plug it if there is a later issue especially if someone gets hurt in march the Lawyers. Im in a rural part of the country at the moment and there are Used tire shops working out of a dozen locations across the county, red neck weekend flea marketers selling used tires and they plug-em all day long. for real service shops right here in town plug tires everyday with no issues. people are just no going to pony up and buy a new tire when they spent a Benjamin or more on a new tire in the last couple years. Lancaster PA, I sure could crush a Warm Shoe-Fly-Pie right now |

They're out also. Few weeks lead time as well. Has anyone ever used any of that plasti-dip stuff to repair a diaphram? Maybe flex seal or plasti-dip could seal the leak long enough to hold out until one of these places have stock... In the meantime, a manual shutoff valve will have to be the go-to. No I haven't had to use anything like that. At this point with you I don't think there is anything to lose other than the money it will cost for some of goop. I would recommend Permatex Ultra Blue, it is designed to work in Fuel and Oil, I don't know and don't think the Flex Seal is designed to do so, but I really don't know for sure. Good Luck |

Pistonguy: I'm sorry but I got a tad busy over the last 50 years. I have NO memorabilia from my teen years except for one pic of the old Hog which appears in several posts. Anything I post is true, and only for the enjoyment of fellow members, not to prove anything. In the military, I held a COSMIC clearance (and yes, THAT was BEFORE it became a NATO designation, with "TOP SECRET" now being the highest US level unless you're a "Yankee White" nuclear-football guardian...so don't bother calling me out on that) and you don't get that level of security if you're a bullshitter. I like CONVERSATION, you like CONFRONTATION... You and I will never agree on anything, and that's fine. It's a free country. I just can't imagine anyone so quick to call a total stranger whom you know nothing about, a liar. And all this venom from you simply because I posted a friendly reply to your inquiry about my old Chinese scoot's exhaust... CHEESH! I'm too old for this. Have a great life and enjoy being right all the time, while demeaning others you know nothing about. I pity the guy for whose trial you ever serve on a jury... Chopperdude you posted something that is technically incorrect and I simply asked why. I have provided both Illustrations and Technical Explanation on how the 2-T system works. I haven't used any language. I have given you every Opportunity to Explain How and Why "It Works" you haven't, Tell us. You stated that a Expansion had beed use in Top Alky with success, ok show us. show us anywhere in Motorsports were they are using a 2-T Expansion Chamber on a four stroke. Simply stating "It Works" with no explanation or documentation then getting all upset that I ask the How and Why is silly, I guess know body over here is allowed to question anything you post? And why should have Pity for the Jury duty I served on? he was 16 year old gang banging punk, did a drive by shooting on Juneteenth and shot a 3 year old little girl in the head and killed her in the Stop Six neighborhood, I hope he is still Rotting in jail. You Pity him? |

I have a tendency to believe actual results on the road over math and physics dogma. I work with an office full of engineers every day. Most of the time, their calculations correctly predict the outcome, but there are occasional anomalies. The two stroke pipe on a four stroke scooter is one of them. 4-strokes and 2-strokes are "apples and oranges". All the technical sound-wave, impulse technology which makes the chamber-pipe so good on a 2-stroke (and ONLY at the rpm tuned for) go out the window when the pipe is on a 4-stroke. I'm not the ONLY guy or gal to discover how well a 4-stroke will run with a chamber-pipe. It's not all that uncommon, especially on scooters both "from the factory" and custom-built. On a 4-cycle, the initial "cone" or megaphone part helps scavenge the exhaust. The reverse-cone then slows it ONLY slightly. The little "stinger" is a straight-through glass-pack. The whole assembly is a VERY low (near zero-restriction) STRAIGHT-THROUGH "muffler" with slightly better scavenging than most other systems. On my old mostly stock GY6, that little chamber pipe (with full-inside-diameter header) probably did not increase horsepower measurably. But, it DID noticeably increase low-end "grunt", gave better pull at mid-range rpm (especially riding 2-up, up hill and into wind) AND provided INSTANT throttle-response... It also made easy work of carb-tuning.
THAT is the truth, and is WHY I posted the "how-to" originally. I rode it that way for two years, and the dealer I traded it to on the Kymco was astonished at how it ran. I heard he kept it for some time as a shop errand-runner because it was just plain fun, with amazing performance for a Chinese 150.
I'm not on a crusade to put chamber-pipes on 4-strokes... I just see red when somebody tells me something I've done successfully many times won't work. Ride safe! And thanks for the insight into "real world" performance opposed to theory. No, I wouldn't have posted the "how to" if it didn't work. Leo No reason to get your Panties in a wad over a Scooter board. You say its works, Ok ya it starts, runs and goes down the road thats all, if ya put a clock on it or Dyno it aint gunna happen... you can see red white or blue, with a comprehensive understanding of the two its just plain silly and a no brainer. The Scooter market are the worst maintained vehicles on the road, mostly entry level kids, and the Most Gullible customers on the market. Just because a supplier lined the pockets of a purchaser means nothing to me. ya just can't show me anywhere in the market place were anyone is adapting Chambers on a Four Stroke. the two T systems Work on Back Pressure and heat, The Singer Diameter and length builds in a certain amount of back pressure, the Sound Waves work Within a Higher Temperature medium, Non of that works with a Four Stroke. There are a few of us elders that have been around but I find most are telling fish stories. ahh don't like it ya don't have to read or really to it, But Im calling you out after read ing for several years of your Drag race exploits with a Oompa Loompa at the helm. those are impressive numbers to throw down and they should be framed if true, convenient you have Non to post. I call Bullhonkey and Utter Bunk. |

If you have a Comprehensive understanding of the two Engines and Systems its a No Brainer. Show me on the Clock or Dyno, just plain silly. Lets put the seat of the panties this way, If my rider had Pizza for breakfast and got into it with his girlfriend the bike runs like crap. When My Rider has the Breakfast of Champions and gets some Morning Dew from the same Girlfriend the Bike is Unbeatable. Same Bike Same Dyno Sheet. |

Call Scrappy, the Diaphragm may be the same size as a 24 or 26mm. I dunno for sure.
I have had great success with Partsforscooters answering the phone also.
