i want to gear my ltz400 lower, do you have any sugestions on what to do, i would like to still be able to go about 60, right now im all stock and top out at about 70mph, will droping one tooth in front make a big diff
or should i go two down

 

Dropping 1 tooth will make a big difference. Since it is so cheap and easy to do I would try dropping one tooth first and if you want to go lower then drop 2 teeth. The torque multiplication at the rear wheels will make it accelerate quicker and feel like it has more bottom end in it.

 

yeah drop a tooth on the front and see if its enough for you.

 

how much top speed would i loose if i droped 1 on the front, thanks for the help

 

you will go from about 66 to 62 i would guess.

 

would i have to take out a link of chain if i drop a tooth or do i just adjust the chain
and use the stock?

 

I got by with keeping the chain the same length and and going to end of the adjustment limit. I would advise taking a link out if you have time.

 

try here gears
this might help you

 

I don't think I would go down 2. After you go down 1, if it's not enogh try 1 or 2 up in rear. Front makes a way bigger difference. I'm going to get 22" tires for mine for mine and 1 down in front and 1 up in rear should bring back to stock final gear ratio (close enough) I haven't actually done the calculation yet, but when I did it for my brother on his 400ex, it came out to a very minor percentage higher geared than stock.(bigger tires make it higher geared, so we did this just to compensate) Since the z has a 1 tooth smaller front sprocket it will make a little bigger difference so I should end up a little lower geared than stock.

 

That's a pretty cool chart mucky. Now I don't have to do my calculations. I see my idea was right about being slightly lower geared. Looks like if I could put a 20 tooth up front and a 25 out back and a plus 1000 rpm cdi I could top out at about 176 mph lol. I would just need someone to tow me to about 25-30mph just to be able to take off and probably need about 5 miles of strip to get there.
