Going from memory here.
Years ago the Yamaha Road Star (carb model not the Warrior) had a fatal flaw. Having been out since 1999, somewhere around 2003 there were reports of crashes due to a mechanical failure.
Apparently, there was a clip inside the transmission that would break without warning. This would cause the transmission to freeze up at highways speeds, completely locking up the rear wheel. Pulling in the clutch had no effect. In 2004 the problem was fixed with a major model upgrade, but that left thousands upon thousands of these 2003 and earlier “ticking time bombs” rolling our highways.
People on the forums were hot about this. Yamaha was indifferent. This went on for a few years. They even got Senator “Nighthorse”Campbell of Colorado involved. I had an opportunity to thank him personally when I met him at a rally.
As Yamaha remained in denial, and the fight dragged on, some owners/members of the forums started to complain and attack the people leading this battle. They were upset that the resale value of their motorcycles was being diminished…..

Yamaha dealerships were telling everyone that it was a made-up story. The problem absolutely did not exist, they said.
Yamaha finally capitulated and did a massive recall on these motorcycles, acknowledging the problem. To this day if you have one of these motorcycles and you run the VIN number, you can find out if the recall was done and I believe they are still fixing them. This involves spitting the motor, which is a major job.
At the time they started doing this they had a Yamaha line of performance mods for these bikes, including some high compression pistons. They offered to install the high compression pistons while the motor was apart and only charge for the parts. Labor would be free. This was a small offer to assuage people who had to have their bike torn down and in the shop for who knows how long.
I put together a turn-key high performance flat side carburetor setup for these bikes. When somebody contacts me with a 2003 and older I have to figure out if they have high compression pistons or not. Most of them are not the original owner and don’t have a clue. Often the 2nd or 3rd owner has no idea if the recall was done and that they might be driving a “ticking time bomb”

. I advise them to run the vin.
