Top Speed

Has anyone have an idea of how fast you would go on a zx14r [gps estimate speed+-] at 11000 speedo revs.

Comparison

1. Standard sprocket set up.
2. 40 t rear sprocket standard in front.

Then measure your tire, plug it into the software, and subtract 3%. And calculate a max rpm of 10900.

Got it but not sure I understand it. The bike gets restricted to 185 mph at 11000 speedo revs and I know it's out so how much is the error. Gear calculator must calculate at true rpm then. So an indicated 11000 = ? true rpm.
Best is to use a GPS then, but I'll have to wait for an event to do that.
Look we have different conditions here in SA and different fuel octane also so not looking to get any speeds close to what for example Shane's wife did.
Shane not planning to beat you Buddy way to far away for that so don't worry.
I would like to see what a normal 14r with minimal mods do on a top speed run.

The tach is near 500 rpm high, compared to actual. You need to derestrict the bike, or you are not going any faster than 186, +/- a little.

I'm not worried...I am giving you the same information I use to calculate gearing and speed.

When you set the little shift light on the 14r is it going off actual rpm or the displayed tach rpm? Sorry for the sidetrack.

No idea!?! I have never used the shift light! Don't you use the tach to set it?

My bike has the Guhl flash so everything fine there. You have been there so you would know! I have the 40t rear sprocket. Just wondering how high it will rev the 40t rear sprocket.
How high did your bike rev on your run?
How do you position yourself on your bike at that speeds; there is mega turbulence and its difficult to see clearly at high speeds.
Some tips would be appreciated.

We have a run a 40T to 211.xx mph, pulling about 11280 rpm on the extended rpm Guhl setup. If you get properly low, you will not have that turbulence. I am a big guy, at 255+ lbs suited...my bike was rock solid, fully clear vision at 206.8 mph.

Tire circumference was around 77" on those runs. Should be close to what you have on your bike.

I would love to run 200 - 205 range.
Last questions: Do you run the standard screen.
Suspension set up.
I'll be happy to run 11000 revs, I hope it would because I have the same Brock goodies.
My tire is quite new so should be the same.
Thanks man, tell you there is not many people running your speeds.

Yes, standard screen. If you are using the Brock map, I suggest fattening it up a little for top speed. Do you have a data logger? A cheap one is a great investment!

Suspension setup...set the bike up to handle the road you are racing on. Keep the wheels on the ground, as per typical roadracing setup. Run a minimum of stock tire pressures, as measured cold. Invest in a steering damper.
