Honda Spree and Elite 50 Forums

So I know this is a tough question to answer, but I'm about to buy a new carb, and I'm considering a brand new oko,polini,or dellorto 19 or 21 mm, but I'm not sure of what size to get. I've got an aero50 w an af05e w a burial pipe, CT mani fold, no oil pump, no porting (but possibly some future work),no gears, and a 63cc alum cyl kit. I want a "performance" oriented motor, and I don't need to go over 50 so I don't think I need or want gears. I see some guys w huge carbs, but I kno that doesn't seem to work the best. I see alot of 24mm carbs, but I've seen that chart G9 found and it seems like I want something small, maybe even stock size(17.5mm)? What carb do I really need? I don't want to waste gas w a huge carb but I don't wanna miss out on some acceleration cuz I ordered the wrong one, especially since a 30mm is about the same price as a 17mm.

Smaller carbs are easier to set up and get running right.
Bigger carbs give you more macho willy waving rights.

Greetings:

Stock venturi diameter on the PA carb is 14mm or so. I ran Flash 2 with an Amal-Arreche 17.5 and saw some nice low-end gains, but with a 65cc kit a 19 might have been a better choice. 24 is pretty large for that displacement. At either 19 or maybe 21mm, the carb will no longer be the "choke point".

Thank you again, wheelman. I think I'll go w a 21mm, just in case I want to do some more work later. I've found out I can get oko carbs straight from the manufacturer in taiwan, and they even help set it up by letting you choose jets and will even swap em if you pay extra. I've heard the polini carbs are okos and the malossi & stage6 carbs are dellorrtos, so I figure I should just go w an oko or dellorto. Anybody think different? I bet G9 haha. but seriously I'm betting he doesn't carry the oko or dellortos for a reason, just not sure why.

Greetings:

The quality of the Polini version of the PWK simply doesn't compare to the OKO clone. I would not have believed it had I not experienced it myself, but to me better enough to be well worth the extra money. Get the Polini. No experience with Delorto, but not a bolt-up mount with a CT manifold from what I've read.

Once again, excellent sage advice from an experienced source. I've been looking for a reason to buy somethin from G9 anyway, he's a good dude.
One more,please wheelman;
You've had several aeros from what I've heard/read, what do you think the best mod is after bbk carb and pipe, and cvt/clutch tuning? Seems like I'm almost done besides port work or locating n.o.s. performance parts w limited replacability. And do you think a metropolitan front fork/tree would work w/o butchering the front panel?

Greetings:

Lacking the resources, welding skills and frankly the Gumption to tackle a fork swap on any of my scooters, I have never swapped a fork. The 95mm front brake panel from a late (1994-later) Elite with Polini shoes has been barely sufficient to rein in Flash 2's frisky 58 MPH, and as far as I was willing to go. It's bolt-on and it'll stop, ONCE, whereas a good disc setup can do it over and over without brake fade. Either way, use a 2.15 Met rim and 90/90 Pirelli SL26 or better tire. The 90 will kiss but not damage the fender if you don't try to lower the forks. Heavier C100 front dampers help more - check eBay.

My fastest run with the Aero happened with a Malossi 47mm top end and 2:1 Malossi primaries, or 7.83:1 final drive. Take-off from 0-10 kinda sucked, but once underway it was fine with light rollers, 36 total grams. Keep compression under 150 with thicker head gaskets, but don't mess with the base gasket.
