Went back to the dyno today...

Yea- http://cb1100forum.com/forum/showthread....light=cams

They didn't do much- but I also picked a mild grind because I didn't want to loose power down low.

I try to look at everything as a package- even bigger, more aggressive cams could ultimately make more power- but in my opinion right now, the cams aren't the bottle neck...and making power is all about removing bottlenecks.

Which makes this all interesting- remove a bottleneck and other 'mods' could make more gains than initially thought.

My guess is next limitation is the throttle bodies. 32mm is small, especially for 1140cc.

Honda design spec likely targeted using 32 mm to meet the performance behaviour they were seeking as well as salvaging some economy. The stock CB1100 is surprisingly good on fuel consumption.

Honda knows how to make a 140 hp 1140 cc inline-4 (recall early 1980s). I reckon that wasn't the spec for these CB1100s.

Yup, memory is off and I didn't intend to restrict to Honda.

Yamaha or Suzuki is likely more appropriate and in the 1990s. Possibly the Yamaha YZF-R1, maybe it made more power and I think was a litre-class bike.
