I upgraded to..

I finally upgraded to a 80cc motor. hell it's a beast!!!

Yay! It's not 80cc! Yay! It's really only 66! Yaaaayyyyyy!

Are you sure your original wasn't 66 as well? I've seen motors marketed as 49 but in reality they were 66 (don't ask me why it just happens.)

some of these motors (regardless of size) are just better than others

Yep, as long as they keep the quality control within several hundredths of a mile chances are they will eventually produce a perfect part by mistake. Eventually those parts by random chance meet up and create a Yamaha quality engine, again by mistake of course, and if you're lucky it makes it to America.

Or maybe it's like the loto, they send an actual engine-out-of-the-box, almost like a big winner prize, to keep you coming back filled with false hope.

I know it's a 80cc. my previous engine was definitely a 49cc because I couldn't reach 25 mph on flat ground.but now I can reach 40 mph on flat ground so.... yes it's a 80cc or bigger.

it's a 66cc, or 69cc if it's a 40mm stroke motor. there's no such thing as an 80cc china girl. measure it yourself.

and put some damn brakes on the thing before you kill yourself. you got hurt more in a couple of weeks under 25 miles per hour than I have the entire time I've been riding china girls at 50+ miles per hour for the past 3 or so years

Sure, just double your top speed in mph to determine your motor size in cc - works every time.

 

[commanderroach1999]

My top speed is 40 mph so 40 × 2=80cc
Like I said 80cc

Ya but three years ago they were still making the 50 mph X 2 =100cc skymonkey horsehawk motors. HAR HAR HAR.

I suppose if the math is right I should be able to get 106 mph from a 212 predator right? Or should I multiply by 4 since it's a 4 stroke ?
