I bought a old 1981 wing that I worked and worked on. First big bike i ever had and I love it. Rode it last year for a bit while working on it but after setting all winter I got it out and after about 3 miles it started smoking heavily out of the left pipe. It has alot of miles and I'm sure it was never taken care of so I'm wondering what would be the best route. Either have motor pulled and rebuilt along with doing carbs and a new clutch or take a chance and try and buy a used motor. I have no idea what this could cost me so any estimates would help. I hate to scrap it since i have so much time in it but i can't afford to go broke fixing it. I will take any advice anyone can give me.
