gearing question

[hartattack]

What is the stock gearing for a 09 121" nytro and stock gearing for a 09 144" nytro?

 

[Turk]

Been covered extensively & they both are 21/39.

can I put a 23 tooth gear on without changing the chain. How much will it drop my rpm.

 

[ShootToThrill]

Stock chain will not work. Why a 23? Turbo or SC?

 

[RollRite]

can I go with a 22 tooth with stock chain then.

Need a longer chain to go 22t. 70L

if i remember right you can go to a 22 without buying a new chain..but i could be wrong

you'll need a 70 link chain with 22....We ran this gearing in 08...better gas mileage and nice top end.

I'm almost positive that 22 will require 70 link chain. Contact Ulmer he will know for sure.

I have Ulmers stage 2 clutch kit which comes with 22 top gear and 70L chain.Stock chain is to short.I seen no increase in top end if thats what your after.

 

[RollRite]

I have stock clutch and I run at 9140 rpm I thought if I would run a 22 tooth gear I would gain fuel mpg and get better top end.

gear chart at Ulmer, I believe this should help.

hey rollrite,change the primary clutch spring to the next softest on the engage and total force,i forget the color,simple fix for your overrev and better fuel mpg and easier engagement for better belt life,i also added a little tip weight to the for better top end,inexpensive parts like these 2 things will give you a better overall performing sled
