How to better the MPG's on my '75 175cc enduro

[NotYourDay]

I currently can go about 50 miles per tank and I have a 1.8 Gallon tank. I get like 27 or so. I dont know what to do. Its a 175cc Carborated 2 stroke. I do ride it incredibly hard, but still...

I also want to keep it fairly easy to switch back to normal, or even riding styles. I mean, Its a classic and VERY low milage so I would like to keep it stock if possible

Have you considered going to a larger front sprocket and smaller sprocket on the rear to give it taller gearing.

That's a tough question! An old Enduro 175 doesn't have much power, so taller gearing would be a compromise. Maybe try 2 teeth smaller on the rear spocket and see how it feels.

If it has an adjustable needle in the carb, try lowering the needle/raising the C-clip one notch. That should lean it out a little in the midrange. The needle is easy to change in most old carbs.

How much weight can you loose?

Get into an aerodynamic tuck whenever you ride it.

Two stroke motors were gas pigs until recently. The exhaust scavenging process blows about 1/3 of the fuel from the carburetor right out through the exhaust. Either get a 4-stroke, or wait intil direct fuel injection becomes available.
