Re: Install a 16 Tooth Front Sprocket
 
The teeth do look the same but the chain doesnt sit nearly as snuggly as the previous sprocket, did any of you encounter that problem as well? Im just worried since the stock 15 tooth was a perfect snug fit while the JT 16 tooth seems to have to short a pitch...

I also noticed in the screen shot that the JT sprocket says "JTF434" while the one I received says "JTF520" could that be the problem?

Wrong part.

That is for a 525 chain not a 520 chain.
If the roller length is 1/4" then its a 520. If roller length is 3/16" then its a 525.
So the sprocket is just a little thinner???

Ahhh crap! I was so excited too!! Yea, the sprocket just doesnt sit completely on the chain unfortunately.

Dang, okay sorry to sound like a complete newb, so is there a part that will fit my current chain or do I need to get a new chain? If so, will a new chain fit both the new front and the old rear sprocket?
I followed bikebandits step by step aftermarket catalog to get the sprocket I currently have so Im not sure where I made a wrong turn :cry:

There is an OEM (Suzuki) part that will fit. The number is posted on here in a couple of places, I think. I got mine, 3rd party, though my dealer.....for about $18, IIRC.

Whether or not you need a new chain and rear sprocket depends on the mileage and condition of the chain. If you get the right new sprocket, nothing else HAS to be changed......if the other parts are in good condition.

Do a little searching on here. What you need should pop right up.

JTF434 is the part that will work. You had it right the first time.

It that is what you ordered, then they sent you the wrong part...

You name of the chain that you have on the bike is a 520.

You just need the right sprocket...

Thanks so much for the info and quick responses! I contacted Bike Bandit and they indeed shipped me the wrong part! They're sending me a replacement no charge and no complications
:2tup:

Re: Install a 16 Tooth Front Sprocket
 
Okay I swear Im cursed with this dang mod. Today's the first truly beautiful day of spring here so I got ambitious and decided to pop in the new sprocket (no problem, right?)

Well, so far I've done everything according to the step by step but now am completely stumped. After loosening the rear axle bolts and fiddling with the chain tension screws, Ive only managed to tighten the chain tension and move the entire rear wheel further back.

How on earth do I get that sucker to scoot forward and loosen the chain? Thanks in advance guys, bahaha Im hopeless

This should give you enough slack at the bottom of the chain to pull with the sprocket enough to slip it on the the splines.

The teeth should look the same as the old sprocket.

Hope this helps.

Changed many times using these steps.
The adjusters must have enough slack to enable the tire to move forward.
