Louis what is the sea level on Shanes dyno map? If texas is real close to Tn. I might have to hit you up for a copy. Good ole Borek.

If I remember correctly it is about 700 feet above sea level. I have you home email somewhere Peyton. I will send you a few maps to look at. I was suprised the Muzzy M14 flies out map and the Brocks Street Smart maps are close. My Ivans map is a little fatter....it's a little slower when we do 2nd gear roll on's. But in the turns it's so smooth. No jerking from sudden off and on the throttle. Marty and Mike have spent hours looking at all of them, looking for what each map had that was different. Gives me a head ache :-)

Louis I am at 640ish foot sea level. I would love to try Shanes dyno map since we are just talking about a 50 foot difference. I was shocked how well the bike ran in the moutains at 5716 elevation,but the air quality was awsome. Shoot them to. Me at 68gts@sprint.blackberry.net when you get a chance please.

I have had my dyno since 1993, and the one thing i stress is honest consistent repeatable dyno operation. With that being said dyno operation has limitations as far as repeatability. There has been many instances where we could not finish dyno work one day and have
seen a 2 H.P. difference the very next day!
Another aspect of our dyno operation is documenting the power levels of stock bikes. It is interesting to see how these mass produced motors vary. Here are examples of the differences in peak H.P....ALL STOCK ENGINES
The 2001-2002 GSXR1000 have a 8 H.P. diff.(133 - 141)
The 1999-2007 BUSA have a 11 h.p. diff.( 146 - 157)
The 2009-2010 R1 have a 10 H.P. diff. (138 - 148)
The 2005-2006 GSXR1000 have a 7 H.P. diff. (144 - 151)
The 2008-2009 BUSA have a 11 H.P. diff ( 159-170)
The 2008-2009 CBR1000RR have a 2 H.P. diff ( 146-148)
The 1998-1999 ZX9R have a 5 H.P. diff ( 121-126)
The CBR 929 have a 6 H.P. diff (119-125)
The VTX 1800 have a 5 H.P. diff (82-87)
2006-2007 ZX14 have a 3.5 H.P. diff (156.5-160)
2008-2010 ZX14 have a 2.3 H.P. diff (158.7-161)...Matter of fact my 14 is the lowest so far, and when i installed the slip-ons the skoot made 161.17, just a tad over the highest stocker!!
Somethings i remember...the Gen 1 Busa has the majority of skoots in the 150-152 range, with 2 or 3 in the 146 range and 2 or 3 in the 157 range.
I also remember what would be my first experience with the power and performance differences in mass produced skoots. Back in 1978 I was working at a Kawi dealer, at the time i believe the biggest in the Southeastern U.S. The owner ordered more than 50 1978
KZ1000's, and we were selling these units into 1979, maybe into 1980. I had the oppurtunity to ride many of these KZ'S, and my young mind and butt was able to notice that a whole bunch of these skoots all felt very similar. I did notice a few that ran rough, vibrated more than the others and were generally sluggish. There was also one that was very smooooth and had enuff power to power lift the front end without the clutch, none of the other skoots would do this. It wasn't until i started dynoing stock skoots that i was able to document the power differences.
Another story...I had a customer that bought a 2005 GSXR 1000 that made the best stock power for the 05-06 years, and ended up making real good power with the pipe.filter/pc3. Unfortunately that power bit him as he flipped the skoot and insurance ended up totalling it.
We took all the gooodies off to install on the 2006 he bought with the insurance $$. While in the breakin period for that new skoot he commented that it did not feel as strong as the 05, and when we dynoed it, it was 7 H.P. lower than the 05. Matter of fact he owns both ends of the power records for the 05-06 years!!
Thru the years of doing heads i have seen some REAL good stock heads, nicely finished with minimal casting flaws, good matches between the ports and seats, and some heads that had terrible flaws. I remember doing a 1987 GSXR750 or 1100 head, i don't remember which. The ports and the valve seats on the left side of the head were almost perfectly matched, but as you went from left to right the alignment of the ports to the seats got worse. For cyl # 4 the mismatch from port to seat was almost 1/8"!! I just did a Busa head that had a couple of exhaust ports where the casting was missing material on top of the seat, making a noticeable trough.
There is prolly a few thousand machining operations to build one engine. Factor in all the plus or minus tolerances and it is amazing how these skoot van be banged down the assembly line as good as they are, with a few exceptions of course.
