Default Evo guts

I bought a 1989 flstc a few years back. I was told that the engine was built to 95 ci....if it was built, it should've been 96 ci. But it runs great with lots of torque thru the entire rpm range. Doesn't even leak oil yet so I don't want to tear it apart yet. Tons of torque but doesn't like to go much over 80/85 mph. (Neither do I to be honest). I'm wondering if anyone has ideas on how to tell if it's been built beyond original 80ci at all just by looking at it. Any ideas?

Just FYI
You can`t get an Evo past 83 cid w/o changing the crankshaft ( i.e. stroker)

Even a stocker should go over 80mph

Curious about what that means.....???

I bought an '89 Heritage, new in 1989. I only did a stage I on it. Loved that bike, ran very well, and I could cruise it at 80/85 on SoCal freeways.....

Depending on what you mean by that highlighted statement, you could have an issue with that bike..
