Yeah down at this level of minutiae there are some really beautifully simple engineering solutions all over the place.  I've got a whole new appreciation for this bike.

 simple and engineering!!!  [laugh] lisa has got all kinds of jokes!!

Hope the wiring harness goes well as I had a time with the Hyper on the tank replacement :P
At least I learned a bit.

Thanks.  Everything plugged back in with no "left over" connectors  :D so I think that part of it is OK.  The routing looks alright but I'm not positive about that.  Won't know I guess until I try and fire it up.

Next on the list is putting the air box back on... THAT could be a problem.

Can you loose the air box and put on K&N pod filters?

No, I don't think so.  The air box is completely buried down in the "V"... errr, "L", plus there's a radiator in front and bodywork on the sides, so you've got the intake runners funneling fresh air from the front of the bike down into the air box.

I think there's even some sort of voodoo science that decides the exact diameter and length of the runners so the air charge, once it finally does get into the air box, provides maximum power when you peg the throttle.

[coffee]  Of course I could be full of poo and have no idea what I'm talking about.

lisa you are over complicating things.

what everyone trys to achieve is the correct stoichiometric mixture (chemical designation for perfect air fuel). that is why companies like ford, chevy, etc. also employ chemical engineers for engine building processes. your air fuel ratio serves two purposes. anti-pollution, nobody cares about, and PERFORMANCE tuning, yeah baby now we are talking. in theory you want just enough air to completely burn all the fuel available. doing the math at 6000 rpm you are talking about one combustion process every 5 milliseconds. remember there is fore strokes for one combustion cycle (intake, compression, power, exhaust). i dont care how good the engineers believe they are, they are not accomplishing this perfect. not in that short of time. performance engines require a richer mixture because of the heat created at those temps will destroy motors (smell of fuel at races). on a regular (not jet or natural gas) engine running regular gas try to get 12.5/13.3 to .9/1 if you had pure octane you could try to get 14.7 to 1.

afr= Mair over Mfuel

Very cool  [thumbsup]

Wiring harness, battery box back in.  Bodywork going back on.  Hope to fire it up tomorrow  [Dolph]

looks great lisa, (except the color)

nice job lisa!!! the black and white tail is cool. especially if you can design a way to incorporate it into the paint scheme.

Lisa, have I ever told you how much I love your bike?   [thumbsup]
It's such a fine line between stupid and clever.

well was there a ride yesterday??

Yes, and no  ;D  Rode the Daytona.  Didn't work on the 999 Sunday.  

I need to put the throttle cables back together and fill it up with gas then we'll give the SBK a try.  We did notice this weekend, though, a real deal-breaker on a potential ride; the forks are out of place in-between the lower and upper triple clamps  :P  Didn't notice this before because the left side clip on was off for so long.  Not sure if the forks are actually bent or if they were just smacked out of whack during the crash.

I'm going to see if we can trailer it over to AMS this weekend and have them give it the once over.
