update chainsaw bike

today I accomplished some things and learned some things so it was a good day.

I had an idea for an improved drive wheel. I tried it and it is at least 50% more effective. That was very good news since it fits into my existing plans for a bike.

Then i found out that my gasoline mileage with the chainsaw33 bike was terrible. It took most of the day but now I know why. There is a leak in the gas tank. Since I have new things coming to use as a gas tank, I just put the bike away. I rode the mtb25 bike instead. It does just as well as the chainsaw33 bike. Probably because it seems to rev higher and the drive wheel is better.
