Whoa- this CB1100 dropped a valve seat-
#5
My guess is just a fluke / casting gap flaw... but until the seat is pulled and casing examined- who knows.

I would hope that there was a visual inspection during assembly...but these days of cost cutting / expedience - who knows.

Anyone have any idea where our bikes were actually produced? (not assembled)

For the last 20 years or more it is not uncommon- 'built in' country- of foreign components of just about anything.

As for your 60mph limit- that doesn't stop you from winding it out from a stop fairly often- and even at 'speed' you can drop it down gears for a higher rev and more heat.

Yea - I can hear the haters now- won't work, no need...tons of miles with no issues, etc... but I prefer to not only relate to many decades of other vehicles...but again as mentioned above- look at any inside pictures available of these bikes- and they are always carbon black buildup gunk!

Even the recent post from someone about sparkplugs...saying they look good for more miles...I thought to myself, no they look like they need to be 2 heat ranges hotter for that persons riding style.

I grew up on 2-stroke dirtbikes as many other have here- and given countless modifications / tuning on many many bikes in the woods...fueling / heat was MUCH more of something we paid attention to / learned - often by trial and error.

Sometimes hotter / colder plug... or even something as simple as- in slow sections pull in the clutch and rave the engine a few times before it loads up...and you need to pull over to clean / replace a plug.
