I should have known 125mpg was too much

[DarbyWalters]

I have already gone over 1300 on the odometer in 21 days on the scooter...my head was telling me good going...but my gut was telling me somethings wrong. Well I did an odometer accuracy test today and the thing was off by an adjusstment of 62.5%...VOILA...it is in KILOMETERS

Still getting 75mpg...still happy I had to go back and adjust the Lambretta Garage and Jeep/Lambretta Garage to reflect the correct numbers.

Maybe after break in, the mpg will be even better...

I think I have already reached "break in"...it did get better just after the first 750km or ~500 miles. Then it improved a bit more along the way.

That really sucks......my Ninja 250 which can go 105mph gets the same mileage. Heck if I did a sprocket change I can get 80mpg. 75mpg is good just not for a 50cc. Sorry about your luck with that.

But can I buy your CRD?????

Well I really think that when I put the 100cc 2 Stroke in the scooter, I will actually get better mpg than I am getting now. It will definitely not have to work so hard...I am always 'full throttle" right now...and...NO you can't have my CRD...LOL.

The allways at full throttle is problably hurting you a lot right now. Also why don't you go to a 4-stroke? Wouldn't even have to mess with mixing fuel then.

Oil Injection...NO PREMIXing required. A 4 stroke 50cc would not even get me going 30mph...I like the two stroke "feel"/no oil change schedule.

2 Stokes make a lot more polution like 100 times more than a car - don't you even care about that??

Well you need to brush up on more current 2 stoke engines. Reed Valve 2 Strokes do not "lose" the fresh fuel charge like the older piston port engines. Also with Direct Injection of Oil from a separate system, the PM (particle matter) and HydroCarbons are greatly reduced (no need to premix oil/gas which caused most of the ppm pollution). This is not a weed-wacker or Go-Kart 2 stroke. I know about the pollution problems in Asia from 2 stroke engines...but that is caused by older (not as refined) 2 Strokes and vehicles that are "over burdoned". They are taking simple "bikes" and making them into three wheel "taxis" carrying much heavier loads than they were designed for.

You also have to compare ppm of pollution to volume of fuel spent. On top of that you need to add the pollution caused by transporting the fuel to your station. If I use 28% of the fuel I was using in my Jeep for my Direct Oil Injection 49.3cc 2 Stroke...the net effect is less pollution overall. My scooter has traveled over 1,000 miles and still has not used even 1/5 of a quart of 2 Stroke oil. I also do not have the added pollution of oil changes and oil filters. The older 2 Strokes would use a full quart or more over the same 1,000 miles. Even the CVT transmission is dry and requires no oil/lubrication that would eventually would become pollution. Premixing, Overloading and Piston Port Engines were the biggest problems with 2 Strokes when it concerns pollution. The simplicity (less moving parts) and power/weight ratio (smaller displacement) of a 2 Stroke allow the use of a much smaller engine than a 4 Stroke to get the same performance.

I know this might go against everything that most of us have learned in the past, but they have made improvements and packaged the products more efficiently. Kind of the same stigma with Diesels of 5 or more years ago.

A 4 stroke, manual transmission, chain drive, is the way to go for efficiency. Sure you'll have a little more maintenance but it's not difficult or time consuming.
