Honda Spree and Elite 50 Forums

Mine runs fine.

I don't feel it to be second gear start at all.

If your are looking to do wheelies.......Then yes, these aren't for you.

Really you want to find the 9:1 setup that Iv'e heard Malossi had at one time.

If memory is correct someone on here has an extra set but won't sell them.

Greetings:

Physics dictates that the engine - however fortified - cannot deliver as much thrust in 7.83 revolutions as it can in 11. The take-off issue is substantial - there will be no wheelies. You can modify the clutch so that it engages at a higher RPM, but that option is limited by the small size of the friction elements. Even the Polini 2-shoe clutch was not that much an improvement.

That said, I never got to try the ZX rear pulley in the SE05 block. I have reason to believe that its larger diameter, mated with the right belt, would return a measure of the take-off performance lost. An intermediate step that did work was the Polini 248.006 belt with a 1mm shim behind the front pulley boss. I'm hanging onto mine in case the SA16 ZX conversion disappoints.

I know that Loco just happened to have an SE50 in his back yard, gathering mold. There are others.

its not so much wheelies i'm after, just as much as keeping up with crazy suburban traffic at green lights. all stock, i could take them until topping out at 37, then i was a traffic cone. booo.

i thought about the zx tranny, but funds are annoyingly limited for a jobless highschool student, and my harbor freight 1 speed "rotorary tool" isn't capable of much. i'm stuck with my last 70 dollars deciding right now between a kickstart converstion, or 10:1 gears, or hold out for malossi gears. decisions, decisions, decisions...

Most of my riding occurs in speed zones with a 40 MPH limit so mad torque isn't super important to me and neither are wheelies by any means.

I bought the gears to maintain 40-45MPH without being WOT to average those speeds. Also to help protect the engine from over RPM damage.

Mine lags a little but doesn't seem as bad as wheelman's "The take-off issue is substantial " comment. It's not like I have to push the scoot with my feet to get it going.

I think the type of area you ride the scoot in should dictate what type of performance out of your Aero is needed .

For where I ride they are just fine.

i guess i'm just asking too much of a 50cc scooter with limited parts.


might as well just....





....swap in a dio!

Very Good Idea..

anybody know if www.50cc.eu is legit? they seem to have a lot of parts i could benefit from (malossi manifold adapter for bigger carbs, amongst other things).


also,

anybody know the top speed of 10:1 gears? what could it be bumped up to w/ ruckus variator and 3.50 rear wheel?

Greetings:

I ordered something from 50cc.eu at some point about a year ago or so. I had no issues with them.

My "calculations" suggest a top of over 50 is possible if you can get your engine to run at a realistic 9500 RPM. Actually I haven't done the math but a bore-kitted Aero of mine did 45-ish with stock 11.097:1s and with a smaller rear tire and closer-to-stock size variator.

You can get an idea using 17" rear tire diameter, the 10:1 gearing multiplied by the 0.7:1 belt ratio x maximum operating RPM. Bet you wish you'd paid more attention in Math Class now, don't you? (I know I do... )

I could have sworn that maddog some where in a past thread had said there were 9:1 malossi gears that were available a long time ago and he had a few sets but wouldn't sell them for the 85-87 Aero 50. (Could be wrong though)

I have read in a few places now recently that these were never available even in the past.

I have no concrete proof since I was not tuning Honda scooters 15 to 20 years ago to see them first hand. (If they even did exist)
Is there someone who has these installed or not?
I know there are experienced people on this forum ,BUT.Is there anyone with experience that goes back that far to say "yes or no" to their existence without guessing.

a new problem has arisen

the other day, while riding to do a little more breaking in, i think i overheated the engine. it started to perform quite poorly, and would die immediately when come to a stop/under 5mph. only started back up while starting with half throttle.

and yet, given a whoooole 48 hours to cool down, it's still doing the same thing. not overheating, but dying on idle, and running poorly.

it was running and idling perfect before, though.

what have i screwed up this time?

check compression, plug chop, check for air leaks and check the reeds.
how was it running early in the break in?
you premixing on top of the oil injector?

first i'll get on top of buyin a compression tester. anyone got a link?

it starts up fine and idles for about a minute, but once it gets warmed up, it dies.

reeds are fine from what i inspected. full closure and all that.
early in the break in, it ran perfect. idled a little high, but ran fast and great. splash of oil in the gas tank along with injection.

i reeeeaaaally dont feel like tearing it all apart again...

check the bystarter. sounds like it is possibly choking the engine out.

went out to fiddle with the carb some more, thinking maybe i messed with something and forgot? but then i remembered it was running fine for a half hour before this whole problem started.


started it up, RPMs went up and down on idle for a good minute by itself, then it died. started it up, died as soon as i let go of the throttle. adjusted various screws and it died all the same. after a minute or two of this battle, it wont even fire up at all.


frustration sets in. possible tension between italy and japan, i assume.

well. tore everything apart as a last resort.

this is what greeted me:



at first, i thought there was just a big puddle of oil on top of the cylinder

further investigation, a good rag wiping, and a few scratches with my fingernail imply that maybe my piston head... melted? i dunno.




heres what scares me- the exhaust side
(dont mind the dirty carb that the camera focused on instead of the piston)



went ahead and reassembled everything.

started right up! idled great! WHAT IS GOING ON WITH THIS DEMON SCOOTER?!
that's its new name. demon scooter.

took it for a ride, and, as usual, the variator nut fell off. marked by the usual screeching of a non-moving rubber belt




EDIT

turns out the variator nut didnt fall off. took the cover off, tightened it up for good measure, and tried to fire it up. can see the starter turning the drive face, i can hear the engine going through its compressions, i checked for spark, and there's plenty of spark for any engine to fire.

but it doesnt turn over the way it normally turns over when it doesnt start.

ususally when it doesn't want to start/when i have the killswitch on, it turns over in a sort of "beat". yknow, one-two-one-two. you know what i mean...

now, it just turns. no resistance, no "beat", it just turns without resistance. i hear compression so the engine IS turning over, there IS spark, there IS gas.


anybody have ANY idea whats happening? i have nooooooo clue.
