more teeth in the front = gain top end, lose bottom end accel

the rear sprocket is the opposite (which is why they call the front sprocket the "counter sprocket")

why the front sprocket first? because it's cheaper, and you can generally still use the same chain.

1 teeth in the front sprocket = 2-3 teeth in the rear sprocket

Well, it's not called a "count" shaft it's a "counter" shaft.


It refers to rotation....

ok... since you all are on here...

I have an extra 600 katana and it sits like all but one day a month...

Time for a chain so Im thinking of doing the sprockets as well. W a 600 that heavy could I get away w just a -1 front or should I go ahead and do the +3 rear while its getting changed?

It's likely not gonna see much on the freeway, this one is solely around town and for peeps to try to ride.

As for the why change the front sprocket...it's quicker and cheaper to change than the rear, but you cant get as precise with your gearing.

stick with -1F +2R, thats a good start, who cares about top speed on the streets. Going +1 -2R takes a long time to wind out but by that time you are hauling .

If I can remember right, 65mph on the gsxf is like 6k in 6th....

the sprockets will be changed anyways so I may do the -1/+2; I just dont want a wheelie monster I cant control(oh wait... its a kan-a-tuna lol)

Due to the rotation of the earth you need this shaft that little mice spin inside of your motorcycle so that you can ride the same direction as that of the earths rotation, therefore, it counters the rotation of the earth and thus is called a countershaft.

Now what really gets me is how the little mice don't die and get all ground up inside the trans.

they're not actually mice. They're the projection of pan-dimensional hyperintelligent beings into our 3 dimensional understanding. Watch/Read The Hitckhiker's Guide to the Galaxy for more clarification.

The COUNTER sprocket is mounted on the COUNTER shaft which is actually the OUTPUT shaft of the transmission. The reason its called a COUNTER shaft is it is the 2nd shaft of the transmission. The INPUT shaft is getting the power and through the gears, the power is transferred to the COUNTER shaft.

I think thats about it.

actually less stress due to gear reduction. shifts will become shorter too.

I use a yellowbox product so I can continually adjust it on the fly(especially if I want to mess w someone)


... I put a 220mph lay over conversion on my 185mph gauges... so I use my calibrator to adjust for the visual display.

I beleive your speedo is drivin off the front wheel so no healer would be needed if you need help with the sprocket change give me a call I know these old 900rrs like the back of my hand! Also the factory pro 2.1 airbox plus kit really wakes the bike up as will a small shot of nitrous
