The bike has about 7,300 miles on it and the ad mentions a recent top end rebuild with about 2 hours on it. It should be good to go for another 7,000 miles at 10,000 rpm. The speedo has that weird cracking that all 70's Yamaha's get, but that's patina, right?
The twin tail pipes look to be in good shape without a bunch of oily dreck oozing out the ends. Two strokes eat pipes and especially baffles due to their unique method of combustion. However, when the baffle gets plugged you can use the firepit in the back of your suburban home to burn it out. Just make sure your spouse is away that evening.
Gianni is Daily Turismo's Pacific Northwest correspondent. He's a lifelong Alfista and grew up riding two-stroke dirt bikes in rural Washington State when no one cared where you rode off road. He wrote this bio in third person, but isn't nearly clever enough to make witty jokes about it. Vote for Manuel, in reverb we trust.
