Re Gearing

Hey team- I'm currently running stock gearing on my 05 (16/44)

I remember hearing something about re-gearing for more highway use (and to 'calibrate' the speedo) Was it one up in the front, for a 17 tooth, and then stock on the back, or the other way around (stock front, 43 rear)

I have been running a o.e.m. 16 front, and 43 rear on my 2002 FZ1, for about a year now. Very pleased with that combo. Still pulls well at all r.p.m. ranges, but great for freeway/touring droning.

Yes, what you're looking for would be like Dean said, 1 down in the rear. Going up one in the front would put you awfully close to the case protector.

Dean,
With that combo did you notice a change in gas mileage?

Yeah, that's 100% what I thought. I took a good close look at that stock countershaft sprocket and hell, it looks pretty tight already- can't really imagine being able to go any larger on the front.

Hey Dean- Ok, yep, that makes sense. So it sounds like it's not possible (or advisable) to use a 17 on the front?

Just roll with the stock front and go down one on the rear?

Thanks man!

To tell the truth, i have not noticed much difference. Course, i never check such things. I just add gas when the gas tank is low.

What i have noticed, is that my speedometer is very close to being correct, on miles per hour. I do not have a speedo healer, so running the 43 rear sprocket, brings the speedometer to almost perfect calibration.

On Interstate 5 in Oregon, there is still a five mile area, in one mile posted sections. I was there this summer, so i stopped at the start of the zero mile marker, and set my trip meter, to zero. Rode the five miles, and checked the trip meter. In five miles, i had traveled five miles, and half of one tenth. So using that, i figure my odometer is off about one percent. Now that is with a half way worn, rear tire. With a new rear tire, i would be about spot on.

So, the 43 rear spocket works well for me.

Hey guys, check this out. Pretty much confirms what Dean shared. Cool writeup called Project Recycle where they put the love on an 04 Skunk!

https://www.cycleworld.com/project-r...z1-html#page-5

Basically, among other things, says the 16/43 combo produces a 6% change vs stock and in essence calibrates the speedo.

Actually, several folks on the forum run a 17 up front, and while close, it does fit. The benefit, aside from the final ratio you're looking for, is that a larger front sprocket will wear slightly slower as well as reduce wear on the chain due again to the slighlty larger circle. Some say fuel mileage improves while touring with this setup as well.

The other thing to consider, albeit small, is the wheelbase change. With the 43 out back, you can slightly lengthen the wb, while a 17 up front will slightly shorten. Slightly.

Front sprockets are the quickest to wear, and also the cheapest to replace. Unless your setup is currently worn near or at the limits, you could just throw on a front sprocket and call it a day.

I run 16/42. The speedometer is just about perfect, and it works with a stock chain.

That makes a ton of sense! So, anything else I should be mindful of when running a 17 up front? It looks like I'll have to take off that 'chain retention' thingy.

Will a taller tire fit?

On the gen 2 it’s common to run a 190/55, instead of the 190/50 stocker. The gen 1 should be a 180/55, another common tire size is a 180/60 which is of course slightly taller.
Taller tire will effectivly lower your gear ratio and decrease cruising rpms as well.

17/43 combo

Hey team, just thought I'd report back with some results. So I slapped on a 17 tooth front (factory OEM from a Gen2) and then went down one in the rear (43 tooth Sunstar)

5,000 rpm will get you 78 mph on the dot (gps).
