Doc--I was thinking of a dynometer, just not one that uses a drum/wheel relationship.

Whittlebeast--I think I'm tracking on your thought about the amount of VE at slightly ABOVE the idle. Here's my thought on why that wall is there--the bike is already moving and most operators instictively go to 0% throttle during shift (not all, but most street riders). Can't really compare an autos drop in RPMS (800) to a 2 cylinder motor while shifting as most street riders drop about 1500RPMs before they get the scooter shifted (about .4 to .8 of a second the motor decels).

Now, there are many exceptions on this forum--heck, Tote and Taz GAIN 800RPMs on the shift when they pilot down the 1/4 (one of these days you will find that stronger clutch plate fellas---one day--second thought you both are thrashing transmissions already)!

Whittlebeast, my question to you is, is that graph you posted a result of data collected from the MAP currently in your bike and then if it is, do you experience the decel pop-pop-pop and then a roll on the throttle with hold on acceleration? Just a fleeting thought on my part.

So whittlebeast--ought to be interesting to hear what else you got to say about FI.


Mr. Doc, Mr. GeeeROCK, and Mr. Silverbullet can make a scooter turn 7800rpm just by looking at it--and they make my head hurt with the tech stuff and developments they have done...craftsmen through and through.
