Do me a favor...measure the circumference of the tire on the rear of your 12. I will measure the circumference of the 200/50 I have on mine.

My .02-
Shane "rolling resistance" (at the tire contact) is a red herring. Stop worring about it.
If you are pushing the bike, it's "rolling resistance" If the engine is driving it, it's, now think this through...... TRACTION. Like I said earlier - contact patch is good.
Ship- You don't think gearing calculators are "accurate"? Do you maybe want to rethink that a bit? They are about the ONLY thing in this entire discussion that IS accurate beyond question. Each revolution of the crank equals a specific percentage of one revolution of the tire EXACTLY. (except for clutch slip which for all practical purposes is zero.) It is essentially a solid connection. I haven't noticed any gear teeth or chain skipping lately. If the actual rpm does not equal the calculated speed there is ONLY one cause - and that is tire slip.
Sometimes you guys scare me

Oh, I thought you were working for lancair.
So how much does the Columbia share in design and manufacturing techniques with the lancair?
Did they start with a Lancair IV ?

No commonality other than general design (Lance drew them both) and construction materials and techniques (all composite, high temp cure epoxy resins). Clean sheet of paper, new company. Our airplane was first called a Lancair Columbia, but after Lance no longer was in charge we changed it to Columbia Aircraft, largely to keep people of thinking it was us everytime a Lancair fell out of the sky.

DM: I have found gearing calculators and charts to not always be exact compared to numbers you actually find while on the rev limiter verified either by GPS or by a sanctioned event's timing system on more than one occaision.
My point was it hasn't ever been replicated anywhere. Even spray guys can't hit that mph on stock gearing/rev limiter/tire. Thats all I was getting at.

I think he has made it pretty clear that what you (and others) are experiencing is wheelspin.

Then Shane, for all practical purposes then if everyone else is experiencing it and can not get past 196, even if they back out of it and get back on it to help the tire hook up again then with all due respect in the real world the zx12r can not go past 196 with said mods.
Don't get me wrong, I understand the theoretical but what one can actually yield while aboard a zx12 are 2 different things. What good is talking about 202 mph from a stock zx12 if you can't ever hit it?
As far as the tire slip issue is concerned, others including myself have run significantly stickier compound, partly to help offset this issue. Results show that the numbers I am claiming are right.
In the end, as Doug stated, it is indeed possible that a sprocket or tire may have been changed to yield the 199.1 so I can and will just leave it at that.

NO, I didn't say that. I said we went back to the stock gearing. Look, do me a favor - figure the overall ratios and the correct tire circumference, multiply it out at 11,400 rpm and tell me what you get. We'll talk.
What article?
P.S. I'm having some connection problems here at the hotel so I might not be right back.

from dyno testing stock rev limit is 11625 on my B1 model. Showing on the tach was app. 12,200. In 6th gear without the bonneville box rev limiter cuts in at 10925, 11500 showing on tach. After extending my rev limiter 640rpm's the actual rev limit is 12,250 with 12,800 to 12,900 showing on the tach..
Doug you said your zx12r dynoed at 187 RWHP that must have been STD. When your same bike was crated and ran by some magazine it only dynoed at 168.9.. I purchased all the archive zx12r articles from all the rags. Your 192.307 run was done according to the article in 1.16 miles...

That distance is correct..
What do you mean My same bike.....? You're not making any sense.
MY bike dynoes 187 with a PC3, a pipe, a milled head and degreed cams. That other bike you are referring to sounds like a stocker.
Your actual rev limit - 11,625 is on the high side of the tolerance but possible.

I think All Muzzy Tests are recorded in STD HP WHich would still be about 180 HP SAE

AND, depending upon what specific dyno it was done on, eh Vince???
My "research" on Factory Pro vs Dynojet convinced me that Dynojet dynos can be very susceptable to individual set up and calibration factors.

zx12richard,
I am surprised the Moderators of this forum let you leave a link up to another site that was just an inflammatory (troll) post to begin with.
PS.

let me double check my reading.. i thought the bike that ran 192.307 was
crated and then sent to a magazine for testing...how much did you mill
the head? is it the same effect as the thin head gasket..

highlights from the article on motorcycle daily.. Doug Meyer rode over the course app. 30 times. temperatures ranged from a low of 75 degrees to 98 degrees . The elevation was 256 feet above sea level. humidity 80 to 90 %...
back up bike was crated,,,,
the normal 1 mile acceleration length was increased to 1.16 miles by shortening the shutdown area and moving the starting point...
Question 1: Were the mirrors removed for your 199.115mph run.. When cycle world did this it yielded 2.8mph
Question 2: What is the best recorded speed of a hayabusa? not the 194 guiness book crap but actual electronic recorded time. Sport Rider 2001 Yielded 191.3 with a small tail wind..

Now someone is trying to get God to lie for them! If god rode a Motorcycle it would be a Green 2000 ZX12R. The only thing we know for sure is whjat ever he rode it would be the fastest on earth or any where else!

His numbers are electronically timed and the best ever... not disputing that..
I think people are ( on other sites) asking if the mirrors were removed for 199.115...
I dont care either way.

With over 1000 posts hard to say I am trolling, I believe Doug done it just because everyone else hasn't duplicated it doesn't mean it didn't happen.........
Was hoping Doug could give some insight and maybe benifit Ship a bit... Ships 118 pounds soaking wet with a wet towel in his hands and believes in the 12....
Some maybe theres something little Ships missing to duplicate it...
Sorry bout the link to the other place but hey were all adults in a motorcycle industry we can get past the crybaby bullshit for the good of the cause.......
I could care less what Dale done here or Fish done there its the motorcycles that interest me not the sight owners...
Oh this info about the 12 may be repeat for some of you but hey some of us wasn't around the first time...

Doug is a nice/good guy and is a founding friend of Bikeland.org, he goes out of his way to help the Members here.
zx12richard if you have a question for Dougmeyer - you can post a question to Dougmeyer, you don't have to do it with Drama, cursewords and links.
