Upgrading Your 49cc Scooter With Performance Parts – Also the Upside of Owning One of These Machines
The scooter started as a basic, cheap, reliable source of transportation. It is a great way to get around the city or to roam the country side with your friends. There are many positives to owning one of these machine. First off and one of the best reasons is the gas mileage these things get. Your basic 49cc QMB139 4-Stroke Scooter will get between 80-120 Miles Per Gallon. Yes 80-120mpg that is almost unbelievable. This is possible because they are very lightweight and there fuel sipping small engines mixed with there CVT (continuously variable transmission). This is in stock form also. You can do some upgrades to your scoot and squeeze all the performance and efficiency out of it. Some of the first and mos basic upgrades you should do are. First put a Performance Air-Filter on there. This will increase the air flow and get the engine breathing more freely. Next since it is breathing in more air you need to move that extra air out of your engine more efficiently. You do this with a upgraded Performance Exhaust. Now if you do these 2 mods your will need to get a little more fuel flowing into the carb. So put a slightly bigger jet in. Normally the 49cc QMB139 4-stroke will be using a #75-#80. So you can go with a #85, #88, or #90. These jets are cheap and you will want to find which size will work best with your set up. Next thing now that you have your engine flowing a lot better is to start adjusting and upgrading your transmission. Get yourself a new set of roller weights. recommend the sliders over the rollers. Just because they will go up the variator ramps a little further and get you a little more top end. Also they move more freely which makes the CVT operate more smoothly. Also you should probably upgrade your Variator to a Performance one. Adjusting your gearing, variator, and all the CVT componets is gonna be the best thing you can do with your scoot. Now that you have done all these upgrades go out and ride and dial your ride in. There is a lot more upgrades you can do but these ones I have talked about are some of the basic and first ones that most people will do.
Another great reason and one of the main factors people buys these vehicles is because in most states you do not have to have the bike licensed or insured to ride it on public streets. So basically you just purchase the scooter and go out and ride. One real big stigma of the 49cc scooter is that you do not have to have a license to ride them on public roads. Well I am not a lawyer and do not know every states laws. I do know that in the state of Missouri …
