enduro76

Thanks for the quick response. Any idea how much I would gain by doing this?

Hello all, I'm new to this forum. I purchased a 1976 dt125 with only 4600 miles and in excellent condition. I enjoy driving it around town. I get a lot of compliments and it's much cooler than a scooter. Is there anything I can do to get a little more power out of the engine? Top speed is currently 55mph if I'm not driving into the wind. With the wind in my face I have to down shift to maintain 40mph.
