dubious +1...When I ride to work...it is like 80mph@4k all day long. Smooth as silk no noise, vibration, buzz etc...especially with stock exhaust...you don't want to bog the engine...it doesn't work until 3500, It is not a v-twin...it is an inline 4 engine. Redline 11-13k...just my .02.

On a side note I got better mpg with the smeg. Right now I have the stock pipes on and get an average of 34mpg. When doing 80 in the fw I am around 40-43mpg. If you want insur. to do 200mph go 1 down in the back otherwise just leave it...just my .02 again  Thinking about going up a tooth or two in the back.

Pulling the flies in a week or so (when the PCIII arrives), so I dont know the "real" characteristics of the engine, but with EFI it should be able to lope along at lower RPM's and get better fuel economy fellas. Look at the LS1 and LS2 vette's and F bodies- in 6th gear they are between 1200 and 1800 rpm at 70mph and pull off up to 30mpg on the freeway. And reve to 6000 rpms. Just some FYI, the comparable Viper gets around 20mpg at 70mph, and even the considerably slower Mustang V8 gets only 25mpg. They both run at higher rpms in top gear.

those are not 4 cylinder engines designed to rev to 11,000 rpm and make peak power at 9000.....
totally different flame speed, combustion chamber, cam duration, etc....and bigger engines
If that was the case the zx10 and gsxr1000 should run great at 2000 rpm too...
I hope we didn't scare him off.... :P

Dubious, how are you figuring speedo error from gearing? I finally got that 16 tooth front on and am headed to Daytona this weekend. Wondering how bad my error will be.

17/16 = 1.06
your speedo will be out another 6% from stock, so it going to read about 14% higher than actual.
Stock error is ~ 8%

How the hell you got that from my plate I have no idea Dubious. But I can guess what you got on your mind.
As far as rpm ranges of engines/cams/heads, the LS1 cams are a 2500 to 6500 cam if you compare there numbers to a Comp Cams equivelant cam. Percentage of max rpm is the key here. Which makes the LS1 the same as a ZX14 (with flies out).
The real decider of ideal cruise rpms could probably be obtained on a dyno if you only cracked the throttle open slightly and ran it up from 1000rpm. Find the max torque and that would be your sweet spot for cruising.

There is allot more to it than that....
moment of interia from crank and vehicle, gearing (taller only makes it worse), torque at that specific rpm, comustion chamber shape, design and compression, ignition timing...
Google piston speed and flame speed,
There's a plethora of information and engineering involved
Hop on your bike put it in 6th and run it like that down the freeway, see how responsive it, is
then put 87 Octane in it and listen, chances you don't even have to listen carefully at 2-2500.

As I said earlier and if the figures some of you guys quoted are correct, if I drop in gear ratio roughly 6%, that only equates to about a 200 to 300 rpm drop. At 70 mph the 14 is hitting 3500 rpm, subtract 300 rpm and I'll be at 3200 rpm. The speed limit on major freeways here in central AZ is 75 mph, so I'll probably be right at 3500 rpm at that speed rather than at 70 mph. We're not talking any gigantic drop in rpm here.
A few of you guys stated that you drive at 3500 to 4000 rpm (in 6th gear) all the time and it's no problem for the engine, I have no doubt since the engine is capable of much higher rpm's. But that also tells me that you are probably not driving the speed limit either, is that correct?
If 3500 rpm is a good range for the bike to cruise at, my new gearing will probably be right around that rpm at the posted speed limit here in AZ and I'll be satisfied. I assume Kawasaki probably geared the US version of the 14 for most American highways, figuring a 65 to 70 mph speed limit.
The small change I'll be making will pretty much keep that ration at 75 mph.
I'll say it one more time, if I need more power I'll simply downshift an extra gear!
By the way, I never use any gas other than high octane! Did I hear correctly that some of you guys actually run 87 or even 89 in a high compression engine like the 14? I hope not??
Thanks,

hey
I'll try almost anything once.... LOL
it didn't ping around 5000 rpm
who does do the speed limit? LOL
100 mph is 5500 rpm...... thats purrrrrrr fect!
75 mph = 4125
all indicated of course.
and yes 3500 is awesome cruise rpm, even better with flies out, then you won't have to down shift...
yes 30 ft/lbs more to the tire on a 500 lb bike is that much better!

FYI and something to think about: Was NEARLY taken out yesterday on my ride home. Idiot driver looked right at me then pulled out anyways, going straight across all 4 lanes into the left turn lane. Not enough time to stop (45mph zone) AND there was a Ford 3/4 ton behind me that woulda sandwiched me if I did. Being one gear down like I always ride in any kind of traffic/city driving, I was able to nail it, swerve to the left and just clear his bumper with only a brush against my knee. The Ford smacked the dumnass in the rear quarterpanel.
Once again, my paranoia paid off and driving in the power versus in economy mode kept me wheels up. Because I guarantee you I would be in the hospital right now if I was up a gear or two. Think that over long and hard my friend. Because when the car in the lane next to you tries to share a lane with you while you are cruising at 3000rpms on the freeway, you will simply not be able to accellerate out of it, which takes away the #1 way motorcyclists avoid unaware cagers.

Hey Sticks,,
I know and have experienced what you are talking about, in fact, they really stress those situations in the national motorcycle driving classes. I don't think I am ever in 6th gear around the city for that very reason. As for the freeways, I am extra paranoid and am always in defensive posture for the unexpected because I've lost two friends to motorcycle accidents. No matter what gear you are in, being ready for the unexpected should be the state of mind of every cycle driver of every moment they are on the road.
I had a situation where I was stopped at a signal on the right lane and a car next to me on the left lane, scanning all around me as I usually do. I see a truck in my rear view mirror coming up on my rear (in my lane) and I knew he was driving too fast to make the stop behind me, I hit the throttle and swung my bike to the right side of the intersection (up on the sidewalk) only to see that truck skid past where I was sitting and almost hit cross traffic in the intersection.
It's the cycle (or car) drivers that aren't looking for the unexpected that usually get nailed, I don't plan on being one of them. If that idiot who pulled out in front of you had been a little quicker, it wouldn't have matter what gear you were in! According to the statistics, 75% of all fatal motorcycle accidents occur at intersections and involve cars coming from the side! According to the reports, the drivers in those cars say they were looking for oncoming cars when they pulled out and didn't see a motorcycle, basically they can be looking straight at you and not see you - but look right through you. Weird but very true!
Thanks,

Yep I had only a split fraction of a second for my mind to decide (based on how fast he pulled out, direction his nose of car took etc) whether I was decelling and going behind his bumper on the shoulder of the road, or around his nose. After committing to either course you'r hosed if something changes. Kinda like playing cards - skill and luck of the draw are required to win the pot.
Not by any far stretch of the imagination the closest or first time that kinda thing has happened to me. Just the first in awhile. I've been spoiled riding up here in Washington State, the drivers are way more aware of Bikes than in California where I learned to ride.

That's not quite what I said.
The more rpm's any engine turns the faster it wears out. It's really elementary, the more miles you put on a bike or a car over time the more it wears. Ok, the ZX-14 is made to turn 3k to 11k rpm all day long and will last 100k miles. It still comes down to adding up all those rpm's over a long period of time, the bike that has the most wears out first. It can be argued that even though the ZX-14 is made to run high rpm's, if somebody drives one more moderately (not bogging the engine of course), they will probably get more miles out of their bike than someone who drives his hard. Engines (racing or street) wear faster when you drive them hard, that's a physical fact. If you drive them moderate there is less stress on the crank, the rods, the bearings, the valves and the overall drivetrain, thus the reason why race bikes or race cars break things a whole lot faster.
So the bottom line I was making is, dropping 300 rpm on the highway may not seem like a lot, but over a long period of time (say 30k to 75k miles) the engine will have turned less rpm's and have less wear. I understand there are all kinds of other factors to figure in (temperature, driving habits, road conditions, type of oil and so on), but the engine that has turned less rpm considering all other factors the same should have less wear. That was my point.
Will I keep the bike long enough to see it, doubtful. But when I sell my vehicles (car or bike) people love to know that it hasn't been abused or driven to it's max on a regular basis. Believe me, I'll hit 11k rpm on my ZX-14 whenever I feel like I need an adrenalin fix, but it isn't something I do all the time. It's nice knowing it's there when I want it!

Not ness changing gears on the fly but changing gears at a stand still. Fuel econ. Racing.
Any ideas?

Can't be done, the chain on a motorcycle is much heavier and wider than a bicycle. There is no room for two sprockets on the wheel nor could you move the chain even if there were. The reason bicycles have more gears is to make it easier for the pedaler, he doesn't have the power an engine has.

Gearing change w/o a correcting device will make you ODO wrong.........it does not have the error that the speedo does stock. I've testing it w/ a 1000+ mile ride of mostly highway and it was within 1%.

Depends on which way you gear...........
If you set the speedo healer to add to make up for the stock 8% error you will get more miles...less the other way.
I am geared 16/43 and set it so the ODO is correct...speedo error is as stock.....about 8% - I like the mileage to be right.....

I'm reducing my rear sprocket from 41 to 39 teeth. According to others, it should take the speedo from 8% off to around 2 or 3% off and would slow the odometer down, so I would think? If the main output shaft is turning less, wouldn't that be the same as thinking the bike was going slower and not as far?
