I just changed the fuel line on my scoot but kept smelling fuel in the garage, but none on the floor. Today I found the leak, like one drop every 10 minutes on the rear tire for a few days now, evaporating before it ran down the tire on to the floor. Fixed the leak but the rubber where it was dripping definitely feels softer than the rest of the tire.
Do you think the tire go back to normal or is it trashed?

Hey, I am putting a foam pod filter on my 49cc, because stock air box is shot , screws stripped and it wants to fall off. The bike ran great with a 75 main jet and stock air box before, seemed just right. But I read you should up your main jet when you do... I am just wondering from those who run a pod filter, how much you changed your main jet up to compensate. What do you think, 80?  ? or what. Thanks. |

Personally I see nothing wrong with *loosening* a variator nut with an impact even if you have the "right" tools.
Isn't it only tighening that we should try not to do?

I get it the 50cc can be fun. I too kind of get a kick out of planing my routes even with a 150 cc avoiding the freeways ect. (and believe that's not easy in calf.) but I've got one ? if for some reason you lost the Vespa would you just ride the 50 and be happy with that or would you be out looking for another Vespa or 150 plus scooter to replace the Vespa. my guess is you would replace it as soon as you could. as the old saying goes it's hard be beat cu.inches (or in this case cc's lol) later. If I didn't have the vespa, I would keep my 49cc and soup it up. I've read about others with 2T scoots that can really scream. Now that I've had a vespa, though, I can't go back to just a 49cc scoot upgraded or not, but I don't want to part with it either. Another part of it my wife really likes my Vespa. So much that she wants to learn to ride it. I told her she can start on the 49cc and work up to getting her endorsement and riding the Vespa. I actually want to encourage this so we can ride together, if she does I'll let her have it and I'll get something else. But I would still keep the 49cc and have three scoots. |

I went to read the reviews and most of them are due to the quality of the bike they got.
I guess I expected not to get a perfect bike out of the crate. To be honest my bike needed a little more help than I expected but eventually I got it all working.

I wanted a scooter that was unmistakably a scooter, that looked like a scooter, rode like a scooter, but with more power. Quite simple really.
I think some maxis push the boundaries of what a lot of people think a scooter is, only really sticking to the bare technical definition (step-through chassis, engine under seat, gas tank at feet or behind seat) while more closely resembling motorcycles in most every other way.
If I wanted something like that I'd get a motorcycle and I don't mind shifting gears. But then again automatic does not define a scooter, there are a few automatic motorcycles and countless manual transmission scooters, like old Vespas and some newer clones of them.

I should add that I wasn't implying " rock" does not know how to use certain tools. Just that the ones tearing up the CVT and whatnot does not know how to . Even if you do "know" you are more likely to do damage using an impact wench on a crankshaft especially on a small engine. The correct tools can be had for less money than an impact wrench and are usually easier to carry. Even if you do use an impact wrench to get the parts off you still need a locking device and torque wrench to put it all back together to spec. When making a recommendation to a crowd you are usually best giving the safe one that has the greatest chance of success. When servicing inside the CVT case the best practice is to use locking tools and a torque wrench. When you watch a factory trained scooter mechanic demonstrate a belt change even though they do have air tools in their shops they most always leave them on the shelf. Sometimes they will use the air tools only for removing fasteners however will still use the locking tools with the air tool and will put everything back together with only hand tools using a torque wrench for tightening the critical fasteners. Maybe I am a bit more critical on this because I was head of maintenance and responsible for enforcing best practice in the factories I was in charge of however its still the best practice and will prevent problems down the road. To be fair, piaggo has a special tool for holding the variator in place on Vespas. It makes it very easy and straightforward. I dont think such a special tool exists for all chinese scooters that is anywhere near as good as the vespa tool. I have one of these Vespa variator tools (an aftermarket version) and it was not all that cheap, but I think you'd have to be insane to use air tools on a vespa, with what they cost. On the other hand, chinese scooters are cheap to buy, cheap to mod, cheap to fix. I don't know if a mechanic will bother taking the extra time to do the best practices on one of these, and in a way I dont blame him. A typical vespa owner pronbably wouldn't hesitate paying $300 for simple roller and belt change, and chinese scooter owners probably don't want to sink that kind of money into their scoots. I admit that maybe I haven't always done the kind of best practices on my chinese scoots (that I would always do on my Vespa, I am meticulously careful with that.) |

I started out with a Kymco 49cc QMB139 scoot because I did not have a motorcycle endorsement and this is the most you can do without one. Of course it was too slow so I BBK'ed it, it was tolerable but still needed more. So I got my endorsement, sold the Kymco and got a GY6 150cc. Then wanted more and sold the 150cc and got a Vespa GTS300. The next part might not make sense, but I kind of missed the 49cc. So I bought a 49cc 2-stroke scoot and ride both scoots. The Vespa can zip down the highway at 80 mph all day long and I ride it most of the time, so why would I bother with the 49cc? When I had my first scoot, I would have to find ways to get places by avoiding all streets with over 40 mph speed limits, too steep of hills and things like that, and in a weird way I kind of enjoyed that. I've discovered new paths through the city I never knew of, and even some short cuts that I never would have discovered otherwise. Another part is a friend of mine has my old Kymco, we went for a ride and I rode my Vespa, it was kind of boring becuase we weren't evenly matched. After I got the 49cc 2-stroke scoot we went riding again and it was a lot of fun. Turns out the Kymco QMB139 with its 72cc BBK is pretty evenly matched with the 49cc 2-stroke (derestricted, but otherwise stock.) The other part is 49cc scoots have awesome aftermarket support, parts are ridiculously inexpensive compared to just about anything else, and I enjoy working on them and modding them. I paid very little for the 49cc scoots I've owned, so even if I mes them up it's no major loss. While my Vespa, it actually cost more than my truck  I have no desire to mod that Vespa, and parts are pretty expensive anyway. Plus I definitely don't want to mess it up. I don't know if this makes much sense but it is what it is. |

I have a 2004 Eton Beamer 2T, 49cc, has the Minarelli Jog motor (like in Zumas) and looking to install the 70cc BBK this summer.
This is supposed to have a Mikuni 18mm carb but it came with a cheap chinese carb the previous owner put on, which was installed incorrectly and damaged. I replaced with another chinese carb which ran great for a few weeks then began to drip gas on my garage floor due to a flaky needle valve, and I decided to just cut my loss on the carb, it was cheap. Bike has been sitting since last october and I want to get it back on the road.
I want to replace the chinese carb with a Mikuni and start riding again, then sometime in summer do a BBK. Is the stock spec 18mm carb going to be too restrictive for the BBK, or should I do a 20mm? And If I do 20mm now is that going to not work well with the 49cc?

I did, they delivered my scoot quickly. Just over a week, which is excellent for freight delivery IMO.
I would use them again if I were in the market for another chinese bike.

Sometimes you literally can't get a float bowl gasket, I encountered this once it was simply not available anywhere. in my case it was rubber with round cross section, was not really possible to make a gasket out of gasket material that I know of.
If you can't find anything Permatex form-a-gasket #1 is not RTV based and is the only thing I know of compatible with fuel that would be suitable for this repair. In my case I reused the old gasket and only used a very small amount around the broken part of it, being careful not to get it in the float bowl. It has to harden up for a while too, I think I let it set up a couple days before running it.

I'd double check your valve timing, if you are off by a tooth it could have that effect

Thanks that was very helpful! That is an answer I wanted to hear, as I did not want to mess with float level any more. Other than the occasional bog, the bike runs great! I rode it all over town today and no issues at all, not starving up hills or around corners or anything.
I can raise the needle but from what you are saying, the slightly low float level means the main jet may now be too small? Aside from the slight mid range bog it does bog when going from idle to WOT, but only for a second then it just screams. I should probably upjet?

Long story short, I had to put my old carb back on my 2T 49cc scooter. I finally figured out the problem all along seems to be that the previous owner messed with the float level trying to fix a problem, and I think he also got the wrong style of main jet installed in the carb, it threads in but is a different height. I got a correct main jet in now.
I am finding the float level hard to adjust right. The tab was already badly bent up and float was tweaked, but after much more bending and tweaking I finally got something close enough to work. Scoot runs great, great idle, great full throttle, just a slight bog in mid range. Float level is probably a tad low but I am afraid to mess with the float tab any more than I already have and break it or ruin an otherwise working set up.
Just wondering, can you compensate for the slightly low float level by moving the jet needle up? Or is my only solution to try to get the float level right at risk of irreparably damaging the float?
