front sprocket
 

can anyone tell me where i can purchase a 16t front sprocket for the gz250.....im in st.louis,misery..oops i mean missouri...any resources will be greatly appreciated..thanx ..and also does this mod void any warranty

It's listed in the "How to install a 16 tooth front sprocket" thread.

Good Job! :2tup:

Excellent photos!

I'm going to have to get one of these myself.

Power of the Forum!
 

I started reading about the 16T sprocket here, waited a week or so and decided to order it. About a day later I noticed folks posting that their orders were back-ordered. Guess what, so is mine! Somewhere in Sprocketville there is a production manager who is scratching his head wondering what happened. Of course, once they ramp up production to meet demand, everyone on the forum will already have one and the already low price will drop to $1.50 as the shelves fill up. Gosh, my economics professor was right - I would use that stuff one day! ;)

i went to that site the bikebandit one and i looked at the one that said 16t but i noticed it said it had 15 teeth is that the correct sprocket

15-16 Teeth
 

Fifteen is the standard non-modified stock sprocket. The 16 tooth sprocket is the one we have been discussing in the modifications. This non-stock sprocket changes the gear ratios and seems to give a smoother ride with less RPMs required and a wider powerband. At least, that is what everyone has been saying (I haven't heard a negative comment yet) and I can't wait to get mine in to see how it feels.

You might want to check out the "how to" link in the postings above to see what the fuss is all about.

Re: front sprocket
 

I went to my local Zuki dealer (where I bought the bike). They had a 3rd party catalog. They got one in 3 days. They also installed it. Cost me (from memory) about $18 for the sprocket and 1/2 hour labor (about $35).

Highly unlikely it will void your warranty (unless you do it yourself and screw something up in the process). I figure haveing the dealer do it makes that tiny chance even less.

There are several other sprocket companies out there, guys.

JT is the one that I have used in the past and the one I am most familiar with.

You can also look up:

AFAM
Sprocket Specialist
Suntour (they may only be for bicycles, I can't remember)
Sunstar
Vortex

There are others, but I can't think of them off the top of my head. If the JT sprocket is backordered, you can just order one through another company.

front sprocket
 

hey for any of you bigger riders who experience insufficient power perhaps a change to lower gearing using a 14 tooth sprocket makes sense here is a link

this will raise rpm by 7% but give more pulling ability and maybe top end.

Re: front sprocket
 

This is a tough call. Most folks find (even without a tac) that the stock gearing allows pretty much red-line in all gears, including 5th.

Your information is correct, of course, but I suspect that it would be of value to only a TINY number of people.......if any at all.

OTOH, it is fairly simple and cheap to try, for anyone who thinks it might be beneficial.
