D I just got back from a great ride around my town on my ryobi ww bike. thing ran smoooooth as could be and I'm getting the best gas mileage yet. I live in a hilly area and it pulls me up the hills pretty well, I pedal a bit- that's my exercise. That 1.5in roller with JB Weld is the best thing ever. If you can get some clean beach sand or play sand and regular set JB Weld You'll love it.
It is tough on the tires but i"m getting consistent speeds and smooth runnung and effortless bump starting. Today I didn't even pull start it before my ride nor did I warm it up. I wanted to be nice to the old folks next door (about 90 each) and not warm it up. So I primed the bulb, pulled it until it almost started took the choke off and rode off, When I hit 9 mph I dropped the engine and let her start, it was fast, then I pulled the engine up and let it getting going properly- seems to race a second when I first start it,then it settles right down, then after a few seconds I let her go and off I went.
What a ride!
