What is the deal w/ all the multiple compression ratios listed w/ bikes mfg's? Some,(Yami & Suzi) have it listed as 8.9:1-11.5:1, etc,,,,do these stand for corrected and uncorrected? If so, why list both? What gives?

OOOF! WTF! I have been diving into the A. Graham Bell book so deep that it totally slipped my mind!!!!! I have been looking at way too much math!!!!! I also think b/c I have been dealing w/ so many air cooled bikes w/ no PV. The good news is, I won't have to fiddle much longer doing the on paper conversion for un-corrected/corrected, as I order TSR this afternoon!!!!! Yahoo!!!!! Bi-Motion has been a big help, but I think the TSR is gonna take all of my stupidity out of it on my end, as when I do it all on paper, the human factor is very present, ya know? BTW Steve, thanks for not helping me look like a complete moron, I did it all by myself!!!!! LOL, let me know if you need any dimensions for TA, I hope to have the software by next Tues. See ya-

Jman,

If it makes you feel better a while back I thought the two represented cylinder compression and crank case compression. :confused:
