let me talk about mine for a second here then maybe you can understand if you set them side by side.
mine is a honda elite af16e engine code. sym and kymco copied this motor. well. probably not this model. they upgraded and made af18e. the upgrades are NOT the motor, the engine. engines still fits the other bores. did have a bigger boost port. doesnt matter, unless you dont boost port match. but it still runs. either way. i dont konw i have an af16e.
eh.. they upgraded, well, carb, airbox, it was also only japanese and canadian market. whatever the body panels
all im interested in heere in the motor. and the final drive. and cvt differences. like, i guess, the belt. it usually tells you and which case it fits to long or short. them are the things that get screwed up on chinese bikes.
but on hte af18e they also upgraded, or changed, the cvt. now these mods, can be squirmed into af16e bike. including body panels. the frames didnt change. thats the thing. or maybe they did. you can modify, i think the gas tank. was moved. i dont konw if you need to modify anything. i havent done it. or maybe it wasnt. they did later. still using the same engine. most of the rest of the stuff stayed the same too. i think af18e used a fuel petcock.
so. im asking about, 3 things here then. there how you take them apart and put them together. each of these usually stay the same. if people switch these things around, you can useually use a whole version as a mod, for a different bike.
..... whatever. ... then thats just whatver. you do it. and dont ask me how to fix that.
now. is there any comprehension to chinese bikes?
do qmb 4 stroke and qmb 2 strokes, match cvt? gears? what about engine size differences? im i guess talking about the yamaha clone and the qmb's. since i dont know much about the 4 strokes. but are there cvt, final drives, matching? and long case short case, just belt length?

I can't say if the 139qmb gears are interchangeable with a 2t engine or not. I don't have experience with the 2t engine. But the gears in a 139qmb short case will interchange with the gears in a 139qmb long case.

af18e is a honda dio. i dont know what sym and kycmo call their motors though. syms have disc brakes and kymco's have 12 inch tires. and im not blind. either. but id like to know the differenvce between these motors. thanks. ... uhm. maybe ill find out if gears match. so, what doyou look for you guys, in performance in gears? do you find what yours is copied after? is it, e-ton? like for the 1e40qmb gears? because, ive heard you guys swap. well if they sell, e-ton .. do they though? i dontknow. then itd be like easier. but i can find maybe a set then. maybe more. later. maybe if i hunt more. maybe if a buddy swaps. maybe i was waslking through a motorcycle junkyard and was wondering, what i could get while there looking for parts for my bike. somethig i need.

 2 up and 2 down can typically yield up to 15% depending on whether you swap primaries or secondaries. 32% gearing..with a 40% increase from the BBK looks good on paper...well PC NotePad and PC Calculator..these days nobody owns paper anymore. But you have to as alleyoop said you will need higher rpms. Then you have friction(inevitable on earth except in a vacuum) i.e. gear friction..tires rolling resistance. Then Mother Nature tosses in wind drag..which is not calculated in a linear fashion. 32% is really steep. Yes I know the folks on the phone told you to get the set you are getting. But is best to do your own math and instill your own knowledge than to take advice from a person that takes phone orders. That is what made Ron Popeil so wealthy with his company..'Ronco' It is his sales pitch. Also false statements that he invented the product. Ok he is an inventor..BUT..the items he sells are not his. Inventors in China sell them to him...that is why they are so cheap and... "BUT WAIT...if you call right now I will send you a second set ABSOLUTELY FREE" He can afford to..Chinese stuff is low cost.  Anyway that 32% is steep..so let us know. alleyoop...did the math..the set you are installing is as you know...very plausible...so also let us know how it comes out..  Glenn I was having problems getting th 14/32 gears shipped out so last time i talked to them i changed it to 13/33 which is good because i dont have to get the small gear pressed since it is already 13. that gives me a final gear ratio of an overall 10.1538 which is perfect right. 25% upgear on the mark. |

I'm guessing the gears wont mesh properly unless you change the 13 tooth gear. The 33 tooth gear you are going to us is either smaller in diameter than the original 44 tooth gear, or if it is the same diameter the pitch of the teeth will be different.
I have two sets of gears one is 16/50 and the other is 16/42. The first set has a 16 tooth gear that measures 28.15mm in diameter and the 50 tooth gear measures 79.50mm in diameter. The second set has a 16 tooth gear that measures 31.85mm in diameter and the 42 tooth gear measures 76.40mm in diameter. Even though both sets use a 16 tooth gear, the diameter of the gears is different and the pitch of the teeth are different.

I see the gears are pretty much the same amount of teeth than motorcycle chain drive (with sprockets).
I love 17T / 36T setup on motorcycles.
I just wonder, if it's good to have 2 even toothed gears; as they will have more wear of specific tooth. if you put an even teeth gear (eg: 16), with an uneven (eg:35), each tooth will see another tooth on the other gear.
