Try 30 hp @5400 & 34 torque @3400rpm

Sick dude indeed...I understand the concept perfectly...you know how tendency’s are. 😎

There is an old saying from the days they would publish HP numbers in the sales brochure.

HP sells cars.......torque wins races!

I read that the goal is to get the most area under the torque curve on a dyno run.......and that is the engine that will perform the best in the real world.

Armen, interesting that you bring up that old 883 class.  As I recall, that class instituted a rule on rev limiters.  The sanctioning body had the crews draw ignition modules from a hat (so to speak) prior to each race.  Seems that the rev limiters had a fairly large tolerance on the factory setting, so the crews started buying up a ton of modules and testing them until they found the one with the highest setting.  To circumvent the cherry picking the AMA instituted the luck-of-the-draw rule.  That extra 25 or 30 rpm before it bounced the limiter must have been a significant advantage.

In a class that tight, every teeny weeny bit helps.  It's pretty tough to do a lot with the power characteristics of a box-stock 883.  I think all they were allowed to change was exhaust, air filter, and jetting.  I believe shocks and a fork kit were allowed too.

I don't disagree.  An engine with a meaty mid-range is killer, and a lot easier to hustle around a road course.  BIG torque numbers also get the job done on a drag strip.  Anyone who has ever messed around with a power adder can attest to that.  Slap some nitrous on an engine and hit the squeeze button and you get max torque just off idle.  Makes your heart stop the first time you try it.  After that first hit you're hooked.  You're on the dark side and never goin back (until somethin in that motor gives up).

For street use, the focus should always be on healthy mid range.  But just look at this power curve.  It's one of my old dyno pulls with a DR cam.  The only reason Teddy shut it down was because he didn't wanna make a mess on his dyno.  It wasn't makin any more power past 6500 but it also wasn't droppin off much either.  All's I'm sayin is when you have an engine that delivers like this, it's hard to exercise self discipline.  You can hardly feel the thing nose over.  It's pullin just about as hard at 7500 as it is at 6500.  DANGER ZONE!  That's why its so much fun.

A question that has eaten on me for a long time is

Is there anything that can be done with that swinging weight to smooth it out?

This bike is a turd, BUT...

It is a lot of fun to short shift it and any RPM.

DBM's dyno shows what's neat about this bike.  It has a lot of OXpower!
