Another item to take away from pic is the alitude statement ( black star).
Honda already new jetting was close with thin margian of error.
I mentioned the pre recall ccr as a side note which most are at (80 mm+). This takes the margin even closer to bad news. At 6.7 and uleaded fuel carb jetting and adders must be in check.
Honda took the easy way out. After all the mfg has a lot to loose.
Sorry Adnoh but I adjusted your quote to suit my argument
.
Like you mentioned above Honda already new jetting was close, had a piston size recall, and took the easy way out by posting an altitude statement.
When they started blowing up engines they recalled it. Tried a new head with angled fins, tried bigger side scoops, tried smaller piston ---- then they gave up.
I bet the machines ran fine depending on outside air temp and altitude.
Can't believe they didn't catch on that the fuel was detonating under certain conditions.
Even factories make mistakes, but that's how we learn.
The reason I say factories make mistakes is because of my racing experience with rotaries.
Back in the 1970's when I was a teen and first started racing cars, Mazda came out with the 12A rotary. Everyone started racing these as soon as they came out and so did the factory. Many blew up. Same goes for the factory race cars. As soon as you went to a peripheral port design it was a death sentence. Reason: there was an
Engine flaw. A friend of mine, an American that lived in Washington state, and built these engines figured it out. In fact some Mazda factory people came out to watch him race at SIR, I think it was there anyways, it was a long time ago memory fades a bit (Seattle International Raceway). Doug's engines never blew. The factory boys had a chat with him and went to his backyard shop. He took an Engine apart for them and showed them what he does. At the end of this tale is that the factory sent him a letter and told him to go to any dealer he wanted and take any Mazda he wanted "FREE" of charge. He did. Moral of this true story: EVEN THE FACTORY F'S UP.
Edit: The rotary Engine is actually a two stroke.
