I looked on the main page but didn't find it on the specs page. I went from 79-87. Anyone know what this engine is from?

Catfish, It's good news to know that the engine can be bored out that much , maybe that will be something for the future.

If you look here under the 1983 185s you will see the motor number matches through the critical part. When looking up motor numbers for Honda you only need to use the first 2/3 of them TB01E-3061215.
