The other 28, 30 and 32mm carb thread keeps going towards rollers, sliders and springs.... Can we have one that only addresses using a large carb for a BBK? When it comes to the electrical system of the GY6, I've got it covered. When it comes to up-jetting and using a larger carb to accommodate other upgrades, I have a lot of learning left.... Now, I know enough to know there's no crystal ball here... So what I'm looking for it the proper way to tune a carb using the "jet" method... =============== I purchased a HOCA 30mm carb to go with a 180cc power kit... I'm concerned it may be too large in it's current configuration.... It has a #128 main and a #40 pilot... What I guess I'm looking for is some good tutorial videos or perhaps a walk-through on how to up/down-jet a carb Here's the carb I'm using, It's a HOCA 30mm, K&N air filter and aluminum intake. Take your scooter for a performance ride. Write down time to top speed, top speed WOT RPMs, and any other data that is relevant to what you want in a ride. Put in a bigger jet. Test it again. If you like the performance, upjet and test again. At some point you are going to find the jet that that gives you what you want. I upjetted my last scooter by 5, from a 110 to a 115. It went faster. I went to a 120. It went slower. 115 was my magic number. Took three whole tries, two really because I started with the 110 already installed. Obviously you want to look at your plug and note your engine heat to avoid running too lean and hot. There are so many variables in these scooters that I think anyone would be hard pressed to just call out a number unless they knew a whole lot about scooters and had actually tried dozens of configurations of rollers, springs, exhausts, intakes, etc. |

Yeah,, I modded my slide so it would move up faster but did not mess with the spring...did you cut a wrap or so off to make it easier for the slide to go up in the carb,,if so how much did you cut off the spring? I have an extra spring to play around with... I hear that Harley guys take a one or two coils off their spring after modifying the slide,,but they dont really notice much difference unless they pipe and jet. How do you mod the slide, Geh? |

but you're the artist in the group so... Would you be willing to draw us a picture of an "updated" Vespa? Can you show us what a Vespa style scooter would look like if you made it aerodynamic and gave it "modern" lines, like car companies have been doing with cars like the Mustang? This is for anyone, but I know Leo has "the goods" to make it happen. No problem if you don't want to. It's practically scooter blasphemy, but I think it would be interesting to see. Who knows, maybe Vespa will take note. I must say what I see of their new scoots is a little blah, like an old washing machine on wheels, stuck halfway between then and now. Can you make it "sporty"? I may try it too but my drawing skills are not good.  I'm thinking "the Lamborghini of scooters" perhaps?  |

Very nice. A scooter Woodie! But, and you're all going to hate me, isn't it time to update that body style? I love old stuff as much as anyone but I think it's a little weird to just refuse to change. Look at the new Mustangs and some others. They look nice, they look classy, but they don't look like they were made 50 years ago. Every time I see that body style I think of an old washing machine. Aerodynamically, the front end looks like a brick wall. I sure do like the wood work though, especially the engine bay. Metal on wood is so sweet. |

Fortunately I have not seen such corruption here. I find that if one is doing the speed limit, one has ample time to stop. It's sad that people have to try to ruin a good thing, often because of greed. I think the cameras are a great tool and it's good that people are investigating corruption for the people. There are still plenty here that if you are not at 5/10 or more mph below the posted you will not be able to stop on the yellow before it turns red unless you do a panic stop and still you may not be able to stop without going over the stop line. Even if you are able to stop chances are the person behind you may not. Its really bad if your on a bike. Choices are try to stop and then go if you end up blowing the red into the middle of the intersection while attempting to stop and take you chances on the guy behind you or maintain speed (some actually speed up) and hope you don't get to red before you pass the camera trigger. Add to that the elderly who went too heavy on their meds, texters and other distracted drivers along with snow birds seeking Florida warmth as a respite from the harsh winter up North and it gets to be quite a demolition derby.I see people texting all the time. They think people don't notice but when they are doing 25 in a 45 and holding up traffic, we notice. I think voice to text software is the answer, but my phone can't even understand simple names when I try to voice dial. It is literally ALWAYS wrong, dialing people whose names sound nothing like what I said into the phone. I think it's unrealistic to try to make people stop texting. You're running late and your buddy or boss wants to know where you are. Do you really want to waste time to stop and text back? No. People don't have the self control to stop, so the answer, as I see it, is to give them a safer way to do what they want to do. As for older drivers, I think people ought to have to take driving tests more often and relieve the family of the burden of having to take away relatives' driving privileges. Self driving cars, autonomous or semi-autonomous, are going to stop a lot of these problems. |

It's a 250cc variator from scrappydog. I don't know about a brand name. I also noticed there are machining marks on the pulleys from being turned on the lathe. Not all smooth and polished like my other variators I've had. Unless it was made that way for better grip, I'd say someone was in a hurry when they turned the pulleys. I can't imagine it's good for the belt. Wow , I also would magine the belt would ware out quicker if the variator face has machine marking on it. If I had a lathe I'd adjust the angle a little. It has plenty of "meat" on it and taking a few thousandths off of it wouldn't hurt it, IMO. |

You'll want to put a shim in with your "boss", to widen the variator a little. I may do the same. I have to see if my shims fit this new bike. All I have is .25 millimeter shims though, which is about .010". The shims for sale online come in sizes down to .004" for very fine tuning. My new variator is so hard on the engine that it shudders on takeoff. The old worn out one worked better. I got the same top end speed but with much smoother take off. Got the same results on two bikes with that same variator. It could be the manufacturer's angle was off by a fraction of a degree on the new one. What variator do u have ?

Everything from the belt back is OEM. Yeah - CDI does not change this. Thought of putting a shim back in the variator --- the thing came with 3 shims (I think all the same thickness), but no instructions. I have none in at the moment.

This is why I am in favor of red light cameras. People need to stop and not just when a cop is around. Every time. ATLATT. All the lights, all the time. People can be such jerks. Problem is that the company in Arizona that monitors and maintains many of the red light cameras and lights around the country sets the yellow so short its hard to not run the red unless you make a panic stop as soon as you see the yellow resulting in more rear end collisions. It can get quite difficult when you are driving something like a 10 ton truck or bus as they just don't stop as gracefully as an automobile or bike and then after a few consecutive lights the brakes may start to fade from the heat adding to the difficulty. The local news channel did quite an expose of this and got the yellows lengthened in many areas since they had gone so far overboard with the impossibly short yellow lights endangering people since when the yellow is too short then the other folks get an early green and drive out across the path of traffic that could not stop during the span of the yellow. Fortunately I have not seen such corruption here. I find that if one is doing the speed limit, one has ample time to stop.

Ouch!  I wish you a fast recovery  Last Saturday I was riding downtown with a ladyfriend on the back, when an A-hole on a BMW skipped the red light on a crossing and almost hit us, my paranoia always makes me take a look at the side lanes on the middle of crossings, I saw him and had the chance to apply both brakes before being hit from the side  This is why I am in favor of red light cameras.

Night is always dangerous. In fact, its more dangerous now than 20 years ago... so many people have super bright HID lights. Glad you made it out alive. Do whatever physical therapy they give you. Not only super bright, but poorly adjusted. Then a lot have 4 lights. I can't count how many times I've had to slow down when passing an oncoming car, thinking, if a deer (or anything) ran out in front of me right now--I'm hitting it. Especially on the back roads. That reminds me. My new scooter has those little inaudible noise makers that animals are supposed to be able to hear. I hope they work. Fortunately we don't get a lot of big animals in the road near my house. Mostly coons, possums, and turtles, and of course dogs and cats. They'll still make you wreck but it beats hitting a deer. |

Coming home from work on Dec 28th, I had a bad head-on. The guy stated he was blinded by lights in his mirror, and turned left into my lane, then proceeded to turn back towards me. I tried to go behind him, but when he turned towards me it was all over. I clipped his fender and landed on the car. I do not remember a thing after seeing his lights turn back toward me, until i was in the ambulance. Full face helmet did it's job. Had a fat lip, but no serious head injury. Broke both arms, and had bones sticking out of my right arm. Something sliced into my knee and did some damage to the kneecap, but they cleaned it and stapled that. I've been unable to do anything, and am just now getting some movement and mobility in my hands. They had to put steel hardware in both arms. Bike was destroyed, and for all my pain, I at least did some serious damage to his car as well. Be careful, I always say you are a target when riding, and now I have the scars to prove it.   Kev I'm glad you made it through. I had a wreck in December. Fortunately I got away with some bruises, a laceration on my leg, and some damage to my hand which I hope will heal in time. Mentally it was hard. I had flashbacks and nightmares, plus now I'm paranoid when I'm riding. Like you, someone pulled out in front of me and, despite my best efforts, I could not avoid a collision. I realize now that I am not capable of getting out of every scenario and that if someone wants to nail me, all they have to do is hit the gas at the right time. On the good side, I know this now and I am more careful than I already was. I hit the brakes pretty much any time someone is at an intersection in the hopes that I can avoid a wreck or at least lessen the damages if I do wreck. I was really lucky. I could be dead or a basket case, but I'm not and for that I am grateful. Get well soon. Oh and have a bone, on me. You sound like you could use some since yours are kind of messed up.  |

Damn! That's some crazy damage! I've been thinking of putting those LED strips ppl put on motorcycles on my scoot to raise visibility. What do you guys think, do these help? I'm going to put some on mine. I think they will help, at least improve visibility from the sides. I also got insurance on my body as well as my bike. I realize that if that lady had merely ran me off the road, her insurance company might have been able to claim that I drove myself off the road, plus if she had not stopped, or she didn't have insurance, I'd be screwed. Also I'll be screwed if I have an accident just by falling over, or f I were to hit something, so I want to be covered rather than facing massive debt. It's expensive, about $1,000 a year, but it beats paying $10,000 or more in medical bills. |

So here's what we've come up with so far. 3-6 seem the best but tell me what you think. Option 1. There would not be room for the scoot inside the car at all. I have alot of stuff I am moving and thats being very minimalistic. I have and entire house full of stuff that I've already begun donating. Option 2. A box van is over $1500 just in rental, fuel would be about $800 for the trip given current fuel rates (which are most likely to skyrocket come spring when I'm moving). I would save a bundle by putting the bikes in it instead of riding them but my friends REALLY want to ride down there with me  Option 3. Looking at the photos of the work it took to but the hitch on, It seems like if I just cut the tailpipes off and left the muffler that the stock Contour hitch would fit the way it was designed (What does it look like to you guys?). It would not cost much of anything to have them welded back on so they would clear the new hitch. That and I already have an old snowmobile trailer I could put the scoot on. That brings the cost of the hitch plus fuel down to about $400. Scoot and my stuff can go on trailer and in trunk. Python in the back seat with its heater running off an inverter, Dog playing navigator. Option 4. Break the scooter down and ship it on greyhound. This would run about $225 but, I would have to make a 200mi drive to go pick it up from Albuquerque and shove it in the car because that is the nearest greyhound station to Taos. Option 5. Sell the scooter and hope I can find a nice Piaggio down there to replace it. and finally 6. Sell the car and get a Truck or Full size van. But I love my car. I bought it new just out of RTC for the Navy. One of 1500 built. If it were not for getting a new job much better than my current I would not make this trip. Its a huge hassle and I have to give away all the stuff I've worked and paid for in the last 6 years. But then again stuff is just that, stuff. However you won't ever be able to pry my hands off of my toys. A guys gotta have his toys Option 7. Make one of your friends drive the scooter or take turns riding it. Get insurance on it first, including protection for the rider/s, then drop the insurance after the trip. You might check with Amtrak also but they have size limits. I don't know what other train services there are. You might throw the scooter in with someone shipping cargo there by train already. There may be forums for such things and there's always craigslist. You might get lucky and find someone there to haul your scoot. A trucker I know used to use an online service to find cars to carry back on return trips for as little as $300. I'd probably go with the hitch and keep all my junk. |
