Any one gone taller on the gearing. I think 1 up on the C/S sproket would be good

my dealer recommended changing the front sprocket for more relaxed 6th gear - just one tooth. I may go that route in the future, but am content with gearing for right now. My VFR turns about the same RPM in top gear as the Ninja.

Yes, its an ok mod..the one tooth larger. Your looking at a small rpm drop, though. This site is fun to experiment with:

Gearing Commander: Motorcycle Speed, RPM, Chain & Sprockets Calculator

On this bike, you cant sprocket change enough to forget how close the ratio in 3rd, 4th and 5th are...they are more like 3a, 3b and 3c in feel.

Still, gearing commander gives you a good feel for the rpm change. And one tooth is barely noticeable.

After reading the Motorcyclist article (I get the mag) I plan on replacing the 15 tooth front sprocket with a 16 tooth. Doesn't sound like a big change but with the slightly taller gearing it would true out the speedometer from reading higher than your actual speed which is common practice for Jap bikes. I'm not positive how the bike reads your speed but if it's electronic this should help correct it.

I'd also like to lower RPM in 6th. What if we went 1 up and 1 down ?

I went 1 up and 2 down and it's perfect, IMHO. Dropped the RPM's 700 in 6th at cruising speed, and didn't make a noticeable difference around town. The bike has plenty of torque, and seems to love the taller gearing.

I did the same as Northern Ninja. Works great. Should have come from the factory with this gearing.

So far the only side effect (besides grinning and thinking kawi should have done this from the factory) is that the healtech gear indicator needs to manually set.

Otherwise this is probably the best thing you can do to the bike... it makes every gear useable and reduces the 7th gear shifts.

I did the 15 to 16 and it definitely makes the gears more functional. Id go 4 it. And I too think it should have come from the factory this way. Only difference Ive found is more effort is needed when doing 3rd gear wheelies.:eek:

Changing front sprocket

Having some issues installing sprocket from Supersprox. Once installed there is just the slightest bit of in/out play on sprocket leaving washer loose. The sprocket they sent me has been re-tagged and i'm not sure its the correct one. Its and RK and has the number "5041-16" on it. See pic. I measure the thickness of the sprocket at the splines and its almost 1mm thinner than the stock sprocket. Anyone else have this prob?
Could those that have successfully completed this mod please provide the P/N for the sprocket they used??? Is the Z1000 the same fitment?? BTW, I have a 2014 N1.
Thanks for any help/advice.
