I am thinking of adding a tooth to the front or removing a tooth or so on the rear. I am looking for more top end with not too much added stress to the clutch. Anyone out there gone one of these routes and have a little feedback. Thanks.

 

I went down 2 teeth in rear and went to 14 up front and still does very good all around

 

This isn't exact science, just "rule of the thumb",

1 tooth in the front= 3 teeth in rear.

 

i went 13/39 with 20" tires..well the previous owner did.

It was slower than hell compared to my 2000

 

From all I have been told and read about, it seems as though the previous owner went the wrong way. They should have gone up a tooth on the front or down in the back to get more speed.

 

it was setup for trails.

it had tons of lowend!

 

I went up to a 14 tooth front sprocket in the front, and down to a 36 tooth in the rear. This is with 20" tires. I wouldn't recommend this though unless you plan to modify your motor, otherwise the gearing is too tall and you end up riding it like a 2 stroke(fanning the clutch all the time).
