Honda Spree and Elite 50 Forums

I searched all over this site and I couldn't find anything about the kinds of gas mileage you 60+ mph guys are getting.

If you have a 72-82cc big bore kit or a stroker kit, post up your mods and the gas mileage you get. Cruising and flogging.

I was going to get a Ruckus; but you Elite owners seem to go much faster with 1/4th the cost.

never get a ruckus. their slow. you can not get them going faster than 50. because their four stroke

Never get a Ruckus, they are slow. You cannot get them going faster because they're four stroke.

I got a lol.

Soooo.. anyone here got a bb kit? I know someone does!

Look in the threads for the past month, there are a few I recall reading that mention this. If I remember right, the 65-80cc kits with bigger carbs either have the same economy, or 10mpg less.

Hah.. yeah good luck with that.

90cc Vento Zip, 49-51 mpg mixed riding
75cc ministroked Corsa Elite 47-52 mpg mixed

All depends on your mods and tune, have seen some setups dip to 30mpg or less, especially full strokers

I'm not well versed with Elite mods; but it would be something along the lines of 82cc kit from vtcycles, with intake, carb, exhaust, and roller weights/clutch springs setup for a 175 lb guy. Decent tires, windshield, and tuned properly with a wideband O2 sensor.

Stock or -10 mpg seems a little ridiculous?? I would have expected around 50-60 mpg raping the throttle, and 65-75 cruising under 50 mph.

Also; do big bore kits suffer on hills?

I can do better in a tuned up metro!

With using a wideband, what Air fuel ratio you looking for on a 2 stroke? Same as on a 4 stroke?

Also, using a wideband would be much safer and acurate than using the plug chop method right?

Your worried about operating temp which is directly related to FA ratio but FA ratio cannot be calculated to temp due to a long list of factors.

Best way to keep a motor going for a long time is to run plenty of oil personally I think any high performance motor should be used with 25:1 (ask burnt toast what happens when you dontuse enough oil) and keep it cool(350-390 Fahrenheit).

But if you're using too lean AF, then you will raise the operating temp, and also cause detonation. So the best way is to have a good AF that won't detonate, and keep the operating temp down with extra gas right?

Like I said GOOD LUCK WITH THAT

Those numbers are just not REAL world experiance when you Mod two strokes

I didn't pull those numbers out of my * either btw, GPS assisted and calculated quite accurately. I have also tried riding with minimal WOT and mostly 1/4 to 1/2 throttle on my Vento stroker before and the gain in mileage was minimal at best. 105main in 19mm carb on that setup 90cc bore and stroker exhaust, dialed in. I also weight 140lbs btw.

Stock Yamaha Jog at 50cc, with completely realistic GPS tested miles got 59-63mpg

feel free to mod away and prove me wrong

You WILL get lean enough to smoke the motor before it starts detonating.

Never claimed I knew the answer, just started pointing out the search feature and suggested reading the forums more.

my post wasn't directed at you.. although getting near stock gas mileage with any kit and bigger carb is extremely unlikely, not impossible, but just the obvious part of being able to run a bigger carb ie larger jet(s) means you'll be sucking lots more fuel.
