Re: The new guy from Oregon
Welcome to the site!
I am guessing that you are referring to a Chinese in frame 2-stroke. They take at least a gallon of fuel to break in initially, about 2 gallons before they are settled in nicely.
A strong frame is a must, as well as 11ga or 10ga spokes and strong brakes so you don't have any unexpected sudden stops.
A custom tank eh? Please post pics if you can. i have been eyeballing a few small dirt bike tanks on ebay right now. Nothing custom, but at least they hold more that 2 quarts of fuel.
Vibration is just the nature of the beast in these little engines, They are not really balanced internally very well. Some are pretty smooth, others will shake the fillings out of your grand children. Break in usually will smooth things out though.
"It's a chinagirl. It's a sometimes fun little engine that often will break your heart. It's disposable.
