Yeah, it got to 58MPH and change in the brisk February air. It seems so long ago... Daytime highs routinely bust 95 and LOWS seldom go below 80. With so little O2 in the air, the comparison can't be fair.

Hi wheelman.
If you have a flat spot in the middle of throttle? I think you can move your needle up., C clip down one notch.

Thanks Ped, You think it's going a bit lean in mid-range? I'll give that a try next time I test-ride.

very nice! running this same kymco pipe currently. have no stock pipe to compare to, but feel its a solid 2-3mph gain. at least at 50cc. curious to see your results with contessa!

Looks great man! Enjoy!

I would adjust the c-clip if I had a flat spot in the middle. Also check your idle screw make sure the O-ring is not deteriorated or missing.

Well, the Kymco pipe looked good, sounded good, but Ms. Wheelperson didn't think the crisper note was her cup of Chai Latte. I did see 52 MPH on a very short WOT run in 92-degree, 98-percent humidity Deepinnaharta ambient temps, which compared very favorably with contemporary performance of the stock SA50 exhaust, but the Veto was implemented and the Kymco is on fEeBaY here. I'll pull it off eBaY if anyone wants it for $65. I pay shipping.

I would love to give this pipe a run. However, Ive exhausted my scooter budget with recent purchases. GLWTS.

So the scooter that zipped up above 58 MPH in nippy February weather struggles to approach 53 now that the ambient temps approach the Century mark. This was a 2-mile Show No Mercy run, right quartering wind astern but it wasn't even 5MPH. The humidity and heat don't leave a lot of O2 molecules per cup of air. I'm even slower on my evening runs!RPM 8600 on 9.1:1 gears, tires at sidewall maximum, back using the stock SR exhaust. Note the temp of 386 again represents letting off throttle. Temps stayed between 350 and 360 with the throat open wide. It's tempting to drop the main from 90 to 88, but probably safer to wait for cooler weather.

You should see how "Punkin" likes it.

Punkin seems to deliver close to the same performance almost regardless of weather conditions. It's less sensitive to wind direction, and just less "fussy" overall - like a 4-stroke is expected to behave.I managed to massage a little more speed out of Flash - not quite as hot the next day - but still a long way from the zippy performance seen in late Winter. Oddly temps stayed a bit warmer - 376 at WOT for the duration of the mile-long run. Wind was helping, but again not a lot of it.

I still seem to need more kicks to fire Flash up in the mornings. If I start it every day, it's a 1-kick operation. 2 days' rest needs 7-8 kicks to ignite. 3 days or more requires 24-25 kicks. I wonder if the hot (115F) garage causes the bowl to dry up so much faster.

A topic that has been debated since the beginning of time is shelf life of fuel. Some say 4-6 weeks...others say longer, depends who you ask. Claims of lasting up to 2yrs with an added stabilizer also could be chalked up as a great way for long term fuel storage or simply a clever marketing ploy. Im not trying to start a forest fire of a fuel debate here...just an open thought.

One thing I know is that fuel evaporates very quickly. The element in fuel that evaporates first/fastest is the HIGHEST combustible element in the fuel. Therefore, over a short period of time the octane level of the remaining fuel would drop considerably. Leaving the user with a less-than-ideal combustion.

I bring up this point simply because your baseline test was in February and youre comparing it to August temp/humidity. Leading one to believe there were no additional tests inbetween. If there had been, you would be able to confirm your theory of weather conditions being the culprit for performance differences with a gradual reduction as the weather slowly turns month by month.

If there were NO additional rides between these months or fuel had been living in your tank from February. Bad gas is a possible gremlin.

Something tells me you ride "Flash" more than once every 6 months..

Greetings:

Not as often as I'd like, and sometimes it goes a week between ignitions. But I got fuel just 3 weeks ago at the station, and usually (when I remember) throw an ounce of Sta-Bil into the 4-gallon jug I use to pre-mix. I'm reminded to do that tonight. Anyway the fuel in the tank at the moment isn't more than a month old. It's not in the gas can or the fuel tank that the trouble occurs, but in the generously-vented carb bowl that the evaporation occurs. What's left in the bowl has to burn off before it's recharged by the hermetically-sealed fuel from the tank, and that seems to be how it behaves on start-up. I ought to take another look at the tiny o-ring behind the mixture screw, too. It seems it's starting to get moist again sometimes. "Modern" fuel additives - especially the "summer" fuel - seem to do a number on the rubber bits.

Hi wheelman.
Yes the fuel does a number on the rubber. I would not use stabil in your gas. It takes away lubrication from your cylinder.
If you're still having heat spikes you can shim up the needle on the carb. You may be able to use a tiny O ring like the idle screw has to adjust your needle? GL.

I have a bucket of Gin-You-Whine Harley-Davidson Screamin' Eagle needle shim washers for the uh, Ahem... Japanese carbs used on the mighty V-Twins. Somewhere...
