My fuel economy was very consistent throughout my ownership. The sprocket didn't change anything for me, essentially. On long flat stretches, it increased my mileage. On very hilly terrain, my fuel economy decreased. the same would have happened with any sized sprocket. Login or Register to Remove Ads |

I only just installed my 16t sprocket.
.... .... .... First impression is.... I absolutely love it! I'll get some mileage numbers and impression of a long commute over the next few days. Oh. And my primary goal is to reduce engine speed on freeway thus adding longevity. We shall see how that plays out. Last edited by spldart; 06-20-2015 at 08:20 PM. |

Mixed mileage on my commute is unchanged.
And since more rpm equal higher stresses on the engine, and this sprocket lowers engine rpm in top gear on freeway about 7 percent, I'm thinking this mod is a great one to consider. I love this mod. Login or Register to Remove Ads |

After reading the various posts regarding the installation of a 16 t sprocket, I decided to try it for myself. Yesterday, I ordered the sprocket and am looking forward to installing it on my 2009 GZ. I will let you know how I like it. I always felt like I needed to grab another gear after 5th. This should satisfy that feeling.
Thanks for the detailed How To video. It's pretty simple, but following someone else's experience always instills confidence into a project. |

Link to carb mod of which you speak?
I wanna try. Oh. And btw. Changing final drive ratio just moves the power. It doesn't lose it. I did notice peak power rolls on around 65 mph or more whereas it used to come on sooner final gear. Last edited by spldart; 09-09-2015 at 08:50 PM. |

How much torque do you need to tighten the nut for the front sprocket?

Put on the 16t sprocket on my 2009 gz. Haven't been able to take it on the beltway at higher speeds but definitely notice the difference in 1st gear and 4th since most of my riding is done at about 45mph on surface streets. I will update you all once I have had a chance to get her out on the highway. I have not noticed a need for the carb jet kit yet but I will consider it after I have ridden for a while.

Thanks for the write up! The verdict is in, I just tried it out and the changes that I've experienced are that each gear adds about 5mph, which made 4th gear reach 70 now with the throttle pinned, but 5th gear had become even weaker

Good news. You should eventually address the power issue though. 5th gear will add life to your engine by keeping the revs down at the higher speeds. Good luck.
