7/06 issue


Dyno chart observation: Regarding smooth lines on the horsepower and torque chart the Yami was by far the worst with lots of dips at certain revs. It may have more peak horsepower than the others, but it's underpowered compared to the rest all the way thru the tach just before it peaks.

...YEA sorry, i dont speak spanish

nigga please that yammi is the hotness and besides no one onthe streets an50% of the track people use th ebiek the way it is meant to be used out of the box... thats sit is butta...:)

woah!!!

who's got the Soda7o typo filter...

i need a translation STAT. english per favore

:roflmao:

beach youare in my world now..
BTW i think JCBlitz has one of the limited production "Soda decoder rings" ever made contact him for more info..

You're right, it's basically a street legal track bike.

and tahts what it is all about using the street liek a track or doick crack on the track
what ever you get the idea :lol:

...i dont. can you hand over that decoder ring now, please.
:P

:moocow: what?



:roflmao: :roflmao:

and don't be stingy with it I am comfusedid too. Can one be obtained in a Cracker Jack box or a Blacker Jack box?:)


:fart:

basically what the readings say are that almost none of the bikes tach's are not accurate, except the cbr. at redline
most of them are at least 1k off . but anyways, i always heard that tach's don't have to be spot on juts the speedo's do. in cars and bikes. but i may be wrong, who knows

Nope, most bikes speedometers are off up to 7%. They will read faster than what you are actually doing. Thats why they sell 'speedohealers'. I Used a GPS to measure my XX and my truck. Interestingly enough. Bother are off by 3% across the board. Close enough to leave alone. At 65mph they read 63mph.

My cheap knock-off SodaDecoda says:

correct

what i dont get is why everyone is so wrapped up in the tach errors even though speedos are always innacurate. maybe its cause yamaha basically tried to sell the new r6 on the fact that it supposedly revved to 17.5?
