Honda Spree and Elite 50 Forums

wish i took more pics during the build.
here are some pics from the recent moped cruise around the island
mine is the one with the blue front shocks

SYM dd50 block
zx trans
pg long pipe
72cc polini corsa ported
boost port matched with bore
intake port opened up
8:1 gears
ncy disk conversion with RRGS drop legs and KOSO 220mm rotor



a friend's ZX super dio


few guys, waiting for the rest


baap's current bike


top speed, slight downhill, long f*cking hold.
max temp 330*F, max rpm 10,660. no faults, no glitches, i read the manual and made sure it was all set right.

Thanks for the pics. One question...didn't the boost port already match the bore?

Nope corsa has a slightly bigger than stock. Its not as big as a malossi bore but not
As small as a stock bore

What's the number you punched into the vapor for tire size? What duration number do you have the ports set at? You rpm to gear ratio doesn't match at all and for one a dio 72cc doesn't make that much toque to match the rpm so I'm questioning the speed claim.

das wat we call a hamma 72 right there 80mph+
only OAHU can

moped on dyno runs

For my tire, i came out with 1250
What duration number you talking about?
Oh and nice truck btw, my friend poated a pic of your truck with starions on instagrab and saod he gpt the pic off the internet. Seen your bike in the bed so im guessing its yours.

@iRiE SOULJAH next cruise not gon be bombing um, bore is half seize and weights is super flat lol

What is the rim size?

I calculated 76.34mph if it were an s block with met rear. A dd 12" could easily make the difference.

^^^10" rim, 90/90 rear tire.
also got my af block, stock bore, crank, gears, rim, tire, and manifold. aftermarket ramp, pulley, weights, springs and 18mm mikuni top 61. on my tom-tom.
anythinng is possible

You have some big hills.

^^lol say whatever you guys want. doesn't matter how steep the hill is or if the calculations aren't right, it was hitting 76 on flat ground and 71 uphill. i don't see you guys hitting numbers like these with a 72cc. i've had this motor for the past year and a half now, nothing has changed.
let me see your guys' numbers with a 72.

ive been reading a lot about you guys in Hawaii and watch some utub vid as well .. i dont under stand why you guys get so munch more speed on your toys then we do and your rpm seem to be higher as well ..

the two things ive seen is..

one
you guys seem to report a lot more speed then us on the mane land ..and you guys show it.. i wonder if its because you guys live closer to sea level ??
two
all of you guys that report top speed like this dont have a air filter on your rides as well ... were i live my motor wood be fried or at less my reads wood be stuck open in days.... dont you guys have dust or dirt on the roads over there ????

Not to call him a liar but I don't consider a vapor to be proof. A gps with video is proof.

Greetings:

Corsa jetted on the rich side and "Wheelman-Tuned" ran 69.9 here in Deepinnaharta. We're near sea level but the O2 in Texas air is scarce due to the abundance of refinery pollution and Longhorn-generated Methane. Island Air is no doubt higher in oxygen content.

I have no trouble believing 70+ from a 72cc scooter that's been carefully tuned by someone with nothing else to live for... Hills don't count in my book. That's because we have none.

Swim- their rpm's are not any higher then the guys here in the states using the same exhaust. Running no filter is a fad right now over there and most of them fry their cylinders often. Majority of all the guys on this forum and on the the hawaii forum are kids still in high school or are under the age of 23. They are the ones that post speed claims all the time and they usually exagerate it by 5+mph. As we all know that another 5mph of topspeed once 70mph is reached becomes more on the science and experience level of engine performance and understanding timing numbers to pipe performance which non of these kids know about. Its the "do as the romans do" and that also means they all claim about the same speed claims to keep it uniformed.when time to prove the speed claim on a cruise when called out ,they make excuses not to prove their claim and expect you to believe them or their friends that they went those speeds.
