if you convert to cc it does not work 4 inches = 10.17cm 3.48 inches equal 7.9756cm 349 cubic inches = 5719cc
10.17x3.14x7.9756x8 =2037.529=124.33 cubic inches

i mix 32:1 on mine with BBK that is what the manufacturer suggested and that is 12 ounces for three gallon container i mix it in, i keep a small container with 4 ounces in it in case i have to stop and get gas on the road i have a 1.4 gallon tank and when it reads empty i still have.4 left and it will take a gallon 32:1 is a lot you may be ok with 40:1 which is 3.2 ounces per gallon whatever you decide which is best for you i would use a good 2 stroke oil and not something cheap

i just clicked on the link and entered the numbers in millimeters and it provided the answer i did not do it myself ,if you do want the math here it is Calculate cylinder displacement from bore and stroke in millimeters. Divide the bore by two to get the cylinder's radius, then multiply the radius by itself. Multiply that figure by pi (3.141), and the resultant figure by the engine's stroke in millimeters; divide by 1,000 to get the cylinder's displacement in cubic centimeters. Using the example engine from Step 1, we divide 50 by 2 (equals 25), then multiply that by itself (25 x 25 = 625), then we multiply 625 by 3.141 (equals 1963.125), multiply again by the 41.4-mm stroke (equals 81273.375) and divide by 1,000 to yield 81.273375 cc per cylinder. slightly lower than the calculator i entered it into, 81cc none the less still , but any 50mm piston kits is usually listed as 80cc some like to list as a 100cc kit don't know why guess it sounds better scrappy dog is one lists the 72cc kits as 80cc and the 100cc kit in their description they say it s 83cc that 100cc guess gets attention. here is an 80cc kit is marked in description 81.3cc www.racingplanetusa.com/cylinder-airsal-sport-80cc-139qmb-50cc-kymco-4stroke-p-138953-1.html?cPath=27987_27989_27995&sessID=4edff5a163fe7ba9ebafc35041a3cb08 |

on mine i know the voltage is supposed to be between 13 and 14 volts, my friend cooked his battery at 17 volts because of bad regulator

is it oil injection with oil tank, my pump went on me and it started dumping a lot of oil in and leaking, when i put bbk in i did away with the oil injection no more problems with oil after that, not sure if you are having same issue, but i feel safer premixing

the 100cc kits i believe are 80cc kits 50mm don't think that you can put a 125 or 150 kit on it, you could probably buy an complete engine and hook it up with some work, if you go to 80cc kit might want to change the crank at the same time

i have had a problem with my idle last few weeks, it starts good and will idle fine for about 10 seconds then the idle keeps dropping until it stalls after that if i start it keeps doing this unless i keep the throttle up manually after it warms up the idle is great , i thought maybe auto enricher and bought a new one no change, tried cleaning the pilot jet too no change, tried adjusting the air/fuel no change the vacuum and gas lines are all good could it be an intake leak, i bought a new gasket but that didn't seem to help and checked the reeds when i changed the gasket and they looked fine no cracks or chips, or could it be time for a carb rebuild

your valves may need to be adjusted the low rpms and dying at lights sounds like it could be the valves, i am not sure about the electrical it could be your regulator

have you checked the fuel petcock to make sure it is working good and you are getting enough gas or not too much may be getting extra through the vacuum line and make sure the intake is not leaking also

you can try putting in a heavier contra spring that would help it drop the scooter into a lower gearing sooner and help with hill climbing keeping rpm's up
