Poor Gas Mileage, Need Advice On Getting It Dialed In

Just like mentioned above, put many more miles on it before doing anything drastic. Also, remember that the " claimed MPG " from the dealer, is NOT going to be achieved with anything other than slower cruising speeds. Just like a car.
 
Flat out on the GEBE 32cc I get about 30.5 to 32mph depending on conditions and slope etc. Im not particularly heavy but I get the impression that the Schwinn cruisers have been built with spare parts from a Tiger Tank - one thing about them is you'll never hurt the frame lol.

As far as fuel consumption goes I get about 20-22 miles per tank but then I usually ride the bike flat out (im not really that kind to the hardware lol). I am toying with putting some model aircraft fuel in with the mix, only a small amount, to see what happens to performance and have ordered a tuned pipe for the bike as well which should make alot of difference..

Hope you enjoy the bike - as regards the reliability of the bike concerned - as long as you dont try and do something like jumping kerbs etc you should be ok - its the shocks that hurt welded joints - avoid that and you should be ok

i currently have about 100 miles on my bike as i just get a chance to ride at the weekends at the moment, i am not sure about the gas mileage but am still have about half the engines tank left in my 1 gallon red jerry tank.

Check your brakes when i first set it up i had my own too tight the pads were just catching the rims but a couple of quick adjustments and the bike seems to ride better.
the speedo shows i have clocked at 33 mph riding the 13 tooth gear, but i backed off as the front suspension forks felt pretty fragile, anyhow i enjoy cruising around at the 20 - 25 mile mark, the bike and engine seem to handle better in that range.

Breaking in, the elders say it takes close to 1000 miles, thats alot of riding but i am going to follow everyones advice and wait before i start putting add ons to the engine. I might try and add a couple of inchs of silcone hose to help quieten down the engine abit.

kawaski i like the add on tank setup you have do you have it blogged anywhere, if not where did you get the tank, is it gravity fed all the usual questions that rookie builders ask sorry.
 
vegaspaddy, I changed tanks , now have 1 gal gas tank from home depot 2.99, not gravity fed, combination pump from carb and pressure from tank. I got a 2 hole grommet and a 1 way valve from any lawn mower shop 4 an echo weed wacker. 1 hole 4 you fuel line the other 4 your vent line with the 1 way valve. The valve lets air in but not out, so a small amount of pressure is built up. Without the pressure a motor will still run ok but top end will suffer a little.

If you put the bike on the kickstand, and push downward on the handlebars, keeping the front wheel on the ground, pivot on the kickstand until the back wheel comes off the ground, and spin the rear wheel with your hand...see if she spins freely, or not. Try the same with the front wheel...make sure nothing is rubbing...he he he. And yes, a good headwind is worse than a hill for me....really slows ya down.

Good Point! I'm sure that if I kept it around 20mph, my milage would improve drastically. GEBE is being quite truthful about it, but under economical running conditions.
