the smallest one (1B20) still weighs in at close to 50 pounds. But you can get one with an electric start! which means it probably has a charging system on it. $1800 for electric start, or $1400 with pull start. Cost prohibitive indeed.
And diesels DO get better mpg, because diesel fuel has more BTUs per volume than gasoline. It's about 138,000 BTUs to 125,000 BTUs for straight gasoline, or closer to 120,000 or less BTUs for gasoline mixed with 10% ethanol (don't use this stuff in your small engines!!).You pay a little more for diesel but do the math........is it really that much more out of pocket for the fuel when we are talking about a 50cc engine that would get over 200mpg.
Assume 4 for regular and 4.50 for diesel. Lets also assume that the bikes get the same mpg (around 200 miles).......diesel should get better mpg but for sake of arguement we'll say the same.
4/200 = .02 ............that's 2 cents per mile
4.50/200 = .022 ........that's 2.225 cents per mile.
So your complaining about paying an extra .225 cents per mile?
