20 mpg

my tubes are routed up to the air box...

I would caution on routing the overflow tube (the one from the bottom of carb) up high. If the float bowl overfills the fuel can then start draining down into the engine.

With a float set correctly, the only attitude I can find where fuel will drain in normal operation is downhills steeper than 30 degrees. I have not found the limit on uphills. When cornering the centrifugal forces pull the fuel out so the angle of the fuel is reasonably close the angle of the carb. The carb should not drain out the overflow on a stationary motorcycle leaned over to at least 20 degrees.

Use a "Dial-A-Jet". It will give much better gas mileage. I use one on my 03 ktm 200exc.

Does the Dial-A-Jet really do what it says it can? I have been really interested with this product espicialy seeings how i am going to make my bike street legal, and the changes in alititude will be great.

I get about 50mpg trail riding. Only a TTR 250 was using less fuel than me this weekend.

My bike in comparison to RM125, RM250 (huge tank), and a YZ250 my bike always goes longer then there bikes do.

did 30 miles at a snails pace, 1st 2nd gear just off throttle and gas was just under the 3 liter line. thats about 6.5 liters for 30 miles all low throttle. doesn't seem like very good mileage to me!!

This "Dial-A-Jet" sounds interesting. Any idea on cost ?

I wonder if you could run your float level a fair bit lower and then it be compensated by the dial-a-jet ?

This would somewhat eliminate the "spillage" from the carby

It costs $75 you can also have a dual system for $150 i think. Look around the site, there are many cool products.
