Getting this thing dialed in. Running 12gr Dr. Pepper sliders with the ultra low ratio gear set and GEH's full-NCY clutch. If the engine is punched it will climb into the mid 7K range (~7,500 or so) .... but at 1/3 or so throttle it cruises along nicely at 55-60mph, the tach at 6,500 to 7K. For me, that is just about where i want things. Your Combination, Motor (and theres a motor combination in itself) , CVT, Gear and the Cam your working with is darn near as good as it gets. 55-60mph at 6,500-7,000 at 1/3rd Throttle, your into the meat of were the Torque is, and there at 6,400 min should have Lottsa Snots wrapping the throttle and getting outa traffic. A very nice Oil Cooled, Large CC GY-6 Scoot. |

Nope. No snow.
In fact, it's 89 degrees right now with powder blue skies.
Lot of good it does me though. Rotator cuff surgery 4 days ago; arm in a sling for a month. Difficult to ride (and illegal, but who is counting that ...) with a sling on.

OK, so our benefactor on DansGarageTalk- Dan Martin - urged me, when he was building SuperEngine, to get am air/fuel mixture system so I could tune without the guesswork. But the system was very pricey. So here is a VERY low cost yet VERY good system anyone can add.  COST: O2 Sensor ...... $ FREE (see below) O2 Sensor Bung ..... $2.  includes shipping Welding bung to Muffler ...... ?? (cost me $10) Wiring ........ $ more or less free Gauge ....... $12.19 includes shipping TOTAL: $25.19 plus the wire Bung: www.ebay.com/itm/160855809633?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AITSensor: www.ebay.com/itm/171914557669?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AITHow it works: The O2 sensor sits in the muffler and reacts to the oxygen content of the exhaust gas. The output of the sensor is a voltage .... 0.2 volts is a very lean condition, 0.8 volts very rich. A perfect combustion gives about 0.45 volts. So, all you need do is read the voltage of the sensor to know exactly how your carburetor is set up. You can actually do this with a simply voltmeter ... but with a nice, fancy gauge only costing $12 it's silly to not get one that interprets the output for you and tells you "lean" or "rich" instead of raw voltage. O2 Sensor: Use an old (no good) sensor from your car; it will probably be fine. In your car the computer corrects the injector duty cycle every 10th of a second or so, using the output of the O2 sensor to know if to inject more or less fuel. Thus, the O2 sensor must react QUICKLY to changes ... and over time loses it's ability to do so and your car will not pass smog. In our scooter we do not care about this reaction speed - an O2 sensor that reacts in a 1/2 second, or even a second, is fine. So - keep your rejected car O2 sensor (or get one from a junk yard) ... as long as the heater circuit is not shot the thing will be fine. Note: do NOT use a "wideband" sensor as it's output is different and cheap gauges will not interpret the output correctly.  Wiring: There are TWO circuits in the O2 sensor: a heater and the circuit for output voltage. The heater circuit just needs to be wired to +12v and ground when the key is on. The sensor output just needs to be wired to the gauge input and ground. So, really only 3 wires: +12v (ignition); sensor-to-gauge; common ground for the heater and sensor output. The gauge similarly needs to be powered by +12v and ground, and have it's sensor input wire hooked up to the O2 sensor output voltage wire. Simple. Here is a short video of it showing air/fuel mixture as the throttle is opened and closed. It shows I have a VERRRY lean idle setup, and a slightly rich main jet setup: View My Video (who knows why TinyPic flipped the video upside down. The file below does not have this problem) View My VideoFound this post by searching. I had the idea to rig up an O2 sensor and gauge to tune my scoot instead of guessing on rich and lean, and decided to first see if anyone had done it before... of course someone had. Do you really need an O2 with heater, is an unheated one OK? Did you drill into the muffler, or the exhaust pipe leading to it? I was actually just thinking of strapping a multimeter to the scooter and looking for the right voltages, and plugging up the O2 bung once it's tuned right, though the gauge is a neat idea. I don't know where I'd mount it though. |

Hey Phat!
I don't know about "unheated" O2 sensors. I just used one I had taken off my car - didn't switch fast enough to drive a car's computer, but was still ideal for this.
Drilled into the muffler - had the bung welded on.
Multimeter will be fine for a static reading (idle), but Ive found the gauge both fun and also good for jetting (let's you see how the mixture varies under different loads). Proper voltage is 0.4v (stochiometric ideal), but will vary from 0.2v to 0.8v or so. Gauge is only $12. I mounted it using one of the handlebar clamp bolts. If you have a covered handlebar you would have to mess around to figure it out.
