I ran a 9.18 stock wheel base with stock gears ( 17/41) ..I never tried anything else .. Brocks bike went 9.00 with 17/40 .. He said the 40 tooth rear help keep wheelys down in first gear ..

I run 16/42 with stock wheelbase and stock height.

ZX14mike,
Any problem with wheelies using your gearing?

At first when i initially pulled the flies before i put on the power comander it wheelied pretty easily when launched aggressively at the strip, but after putting on the power commander it has even more lowend power and it spins alot when launched aggressively.......but keep in mind its a pretty poor track and i have done no prep to the bike like lowering it or lowering tire pressure.
I love this gearing, i changed to this gearing at like 50 miles and would never go back..........it is way snappier and accelerates much harder without being too busy or busy on the highway...........i think this gearing is the perfect combination for street and strip, i've even driven cross country with this gearing and still think its perfect................and no, i most certainly would not say wheelies are a problem with this gearing, although it will certainly wheelie much easier than stock when launched at 5000 with decent traction.

The 14 certainly isnt a "wheelie" bike like a ZX 10, so you shouldnt have Wheelie problems with 16/42.............if your a lighter guy and go with 16/43 or 16/44 on a stock wheelbase then you might have wheelie problems..........but in general the 14 doesnt wheelie unexpectedly or unless i want it to.

I disagree with the 14 not being a wheelie machine. On my bike with stock gearing (17/41), PC3, Flies removed, TwoBros Exhaust.....I can do wheelies with little input. (remember; we pulled the flies so now we've got more trq right off idle). In 1st gear - approx 20 mph all I need to do is give the throttle quick blip and the front end comes up. Not the roll off then roll back on type input, just a quick blip and up she goes. Logic would suggest that if you replaced the 17T stock front sprocket with a 16T version; wheelies will be created more often and be easier to create, perhaps including 2nd gear wheelies as well. If you change the gearing you will get wheelies; it's that simple.
If you don't want the wheelies, then put the flies back in.....

Road rage, when you say wheelies with little input, do you mean the front end gets light or does a 6inch to one foot acceleration wheelie or are you talking a 12 O'clock wheelie, also are you tucked in in a crouch or sitting upright?
because when i get on it hard in first and occasionally second the front end gets light and might pull a 6 inch to 1 foot acceleration wheelie but never an 11 or 12 o'clock unless i'm sitting upright and whack/blip the throttle actually wanting to pull a big wheelie...........most powerfull bikes will do this but at least in my experience the 14 is not wheelie prone at all the way a ZX 10 or 2 stroke MXer would be, those things will pull 12,oclockers without wanting to just accelerating where you have to let off the throttle.

Road Rage, i guess it depends on what you are comparing it to..........the 14 will most certainly pull wheelies if you want it to, but compared to the lighter zippier 1000's with much shorter wheelbases it is much more stable and planted and less wheelie prone......at the strip i toss the clutch between 4000-5000 RPM and go WOT and while the front end maybe light or 6 inches to a foot off the ground at times through first it is very manageable..............not so with the 1000's..............just ask smoking who is a MUCH better rider than me and most of the people on this board.

Thanks ZX14Mike,
I failed to mention that when I change the gearing on my 14 the bike will also be lowered in the front and back by 1.25 inches. Just didn't want to buy the 16/42 gearing and then maybe have to buy additional gearing. This gives me a good idea that I should be okay with the 16/42 gearing.
Thanks for the input I really appreciate it!!

Yep Mike, you got it right....the front will come up about a foot off the ground, ride out and return to the pavement as speed increases or will rise then fall sharply back to the ground if you close the throttle (the small choppy type wheelies); all while sitting up straight. Agree, it's not a 12 o'clock type wheelie but it's still a wheelie and in my book they all count. I guess I should have added some clarification when I posted what I did but I kinda figured those reading knew what I was attempting to describe as fellow 14 riders. However, even in the case such as we both described, the throttle input needed is (at least in my experience) less than 1/4 throttle to create those wheelies. If given more throttle (perhaps 1/2 or more) and for a longer duration, I could surely get the 14 to come up alot further and I think you'd agree, all while still being geared stock (17 / 41). So, though there are some slight differences in what we mean, the truth is still the same. The ZX-14 will do wheelies (as easy as a 1000 cc bike; NO........ not in stock form), but if you start fooling around with the sprockets it for sure will do them as easily as any 1000 cc bike on the road which is my point.
So again I state, if wheelies aren't wanted out of your ZX-14 then stock gearing should be left in place and perhaps even the flies as well.

EXCELLENT clarification Roadrage..........btw i'm not trying to argue with you here i hear lots of guys say very similar things to what your saying that the Zx 14 is a wheelie machine and it comes up at 1/4 throttle and wheelies in 2nd and even 3rd sometimes..................that hasnt been my experience though, i leave the line at 5000 many times, toss the clutch instantly and go full throttle, the wheel is usually no more than 6 inches of the ground and rarely comes up in second...........now that could be because i am at 4000 feet elevation or because when i do get on it to launch i am usually in a crouch and leaning forward to prevent big wheelies and get max acceleration. Again i'm not saying i dont believe you or trying to argue but i'm geared 16/42 and have the flies out and a pipe and i go full throttle all the time off the line and all the way through 1st gear and i've NEVER had to let off because of a wheelie getting too high like i have on big 2 stroke mXers or 1000's.
At least for me bikes like the 1000's and kx or cr 500's or real nasty 250 2 strokes that I find very wheelie prone require a totally different launching technique were you gotta slide the clutch out slowly and dont go full throttle right away.........my 14 i just toss the clutch and go full throttle instantly...........smokin says his techniques are similar so i'm in good company at least...........now if i can only get times like smokin!

One additional point i'd like to make, wheelbase helps or hinders wheelies just like gearing does. I've never tried 16/40 gearing myself but i've heard that going to what might be max wheelbase with a stock chain would most likely be no more wheelie prone than stock because although the gearing is lower the wheelbase is longer to fight the wheelies...............thats part of the reason i think why 16/43 gears are so wheelie prone its the shortest wheelbase with a stock chain with the lowest gears.
What your saying is certainly correct, pulling the flies and using lower gearing will make it wheelie easier but in my opinion its not unmanageable or too wheelie prone like some bikes.

ZX14Mike,
What is your best 1/4 mile time with the 16/42 gearing on stock wheelbase?
Thanks!

i got my best today but i still got at least .1 left in it, 17/40 gearing,
1.58 60
4.06 330
6.05@122.7 1/8th
9.31@150 1/4
this was my 4th pass in 25 minutes, it went like this 9.50x, 9.40x,9.40x, and then this. so i know if i let it cool down i would of def went 9.2x on that pass.
bike is stock w/b, full tiforce,bazzaz,Mr9 this was in 88-90degree day w about regular humidity about 60s, bike wants to wheelie alot, i tried leaving harder but with no luck so far, i'm still new at this though and have like 40-50 total passes on it. I weight 185 unsiuted btw, 120ft above sealevel.
