This is the second volume of Petersen's long-awaited Donny's Unauthorized Technical Guide to Harley Davidson 1936 to Present. This twelve-volume series by the dean of motorcycle technology examines the theory, design, and practical aspects of Twin Cam performance.
Donny studied privately with Harley-Davidson engineers, having worked on Harleys for over 35 years. He founded Toronto's Heavy Duty Cycles in 1974, North America's premier motorcycle shop.

A no-brainer
They taste good, arrived in great shape with no bruises, pricing can't be beat, and were just on the verge of being at peak condition which is just what you would hope for....not green anymore but good for several days. What's not to like? Prompt delivery. I don't know how they do it but they did. Five stars earned.

Just right bananas
Buying more groceries on Amazon lately. So, want to start sharing experience. The bananas were just right—not too ripe and not too green. Would buy them again thru Amazon

Received a perfect bunch!
Some things are truly hit or miss with Amazon Fresh grocery deliveries!
I Some things are truly hit or miss with Amazon Fresh grocery deliveries!
I hadn’t ordered bananas for about a month due to what I’d received in the past.
Personal preference? I want those lovely pale green ends! Please!!! I don’t like the flavor or even the change in scent that happens when bananas turn darker yellow, freckle - or worse? Turn brown. Yuck.
Each previous delivery, I hadn’t been able to eat more than 3 out of each bunch because of the already yellowed fruit received. I even tried the currently trendy recommendation of wrapping the individual stem ends in plastic wrap to help slow the ripening process.
Was very pleased to receive a bunch of 6 small sized bananas, all delicately green and completely beautiful!
Beautiful job by the thoughtful delivery person as well, who didn’t just leave the bags in the rain on the (only 2!) steps, but made sure they were under the protection of the porch and not blocking my door.
Some items I never order anymore (beloved snap peas and garnet potatoes are two examples) after receiving spoiled items - more than once.
Apparently notifying Amazon of our understandable disappointment, not to mention the waste! can sometimes improve the quality of items delivered.

Nice size bananas. Not bruised or spoiled. Good bananas!
Really beautifully picked for ripeness and last a few days once you get them home.
