Who has gone to a 41 tooth sprocket in the rear?

I am thinking about going to a 41 tooth sprocket on the rear of my kfx400. I am looking for a little more low end torque. I was wondering who has done this and if you like it or not. Also am I going to need a longer chain?? Or can I get away with the stock one? Should I get a aluminum or steel sprocket? ( I do not race)
Thanks in advance!!!!

Have you gone to a 13 tooth up front yet.. Makes a world of difference

No I have not, I am afraid to lose to much top speed

Man i never even come close to top speed on the track, hell i don't think i even get into 5th. What do you need top speed for other than riding down a gravel road?

I actually spend a good amout of time on gravel roads. I had mentioned in my original post that I do not race

You're not going to notice that big of a difference with going up one tooth. I put on the 13t front and love it. I enjoy the compromise of top speed vs less clutching in the woods, climbing hills, powering into short distance jumps, and the wheelieing power.

So the 13t give you better pull through 3rd and 4th gear? Did you have to get a new chain or can you just adjust it out?

I adjusted mine out but if I were to do it all over I would get the newer chain just so I have more adjustability

So can be done both ways then thats cool.

Yes switch to a 13 front! Definately more power than switching to a 41 in back!

someone correct me if im wrong but....

1 down in the front equals to 2 and 1/2 up in the rear

so if you wana go up in the rear 2 or 3 teeth, u mine as well get a front 13 tooth sprocket (1 down in the front).

Posted by: jonboy

That would be correct Oh Sober one!

how come no one ever does bother like i have?
we went down to a 13t in front and up to a 42 in the rear,

likes its been said, you'll never really need 65+mph in a harescramble, so why not take it all the way down where 2nd is the lowest gear you need to be in

IMO i would go up in the rear before i went down in the front.<---that sounds hilarious huh? my brother has a 42 on his kfx and he likes it alot. i dont want to sacrifice anything on my Z so i keep it 14 and 40.

Hey is it gonna make that big of a difference going to a 13t with 18's in the rear?

Posted by: jonboy

Yes, it will make a pretty decent change with 18"s verses the stock 20"s. I noticed a big difference puttting the 13T with stock tires so, 18"s will definately be lower.

Also, My friend Brandon has the 13T front and 42T rear and it is a torque monster and he likes rockin out wheelies for miles and miles.
