Sprocket
 

Hey,

I noticed that the OEM Suzuki sprocket has a sort of rubber pice to it, and looks to be a bit more heavy duty.
Any reason or function that anyone can speak of for that rubber washer part on the OEM?

As well, when you said you adjusted the chain tension, by how much?
More slack, less? how much less?

Im going to do this mod myself, but I want optimal chain tension.

Thr rubber is supposed to make things a little more silent overall. Most reports I have heard say little to none for noise abatement. I believe SunStar still supplies Zuk with their sprockets and they are good quality items. Shop online for the same at a lower price than your local dealer or support dealer til you need really need him. It's all a matter of choice.

Jordan,
I adjusted the chain tension to meet the regular specs. Check the service manual for this info. Just tighten it up to where it should be with a normal sprocket. the amount needed depends on your current chain tension.

Outstanding, excellent how to. :rawk:

Something tells me to get the Suzuki sprocket with the rubber sound deadener. I think by the looks of it it seems a bit more sturdy than the aftermarket ones, and although it may not make a major difference in sound? Im sure it makes some - in quality as well.

Dunno.

I think I can find a good salvage OEM for the same cost or less as an aftermarket.

There is no OEM Suzuki 16T sprocket that will fit our bike. The rubber sound deadener (if that's even what it is) has no fuction. What I mean by that is that there is no difference at all between the 16T JT sprocket and 15T Suzuki sprocket besided increased cruising speed and decreased RPMs.

Assuming that the quality of the aftermarket is inferior to that of the OEM sprocket is a mistake. After having this thing on for 200 miles now, I can't imagine why Suzuki wouldn't make this sprocket standard for our bikes.

The decreased revs at cruising speed make for a much more pleasant ride. There is no longer a nervous feeling above 55mph. The bike settles and it much more capable of making long distance rides.

After riding quite a bit, I've noticed an overall decrease in 0-60 times, but it's negligable. The increase in every other aspect outweighs it anyhow.

Actually,

I spoke to a dealer and the parts guy and there is a 16 tooth sprocket that will fit the bike.
It is a bit thicker/sturdier, and the rubber piece does do some dampening.

Im sure the aftermarket part works fine, but Ill stick with the OEM.

In any case, I wonder what a front AND rear sprocket change would do..

Changing both sprockets to achieve even lower RPM might be counter productive. The 250 only has so many horsepower to work with and you might actually make top gear useless. You wouldn't have the power to pull real tall gearing.

I wonder if that would be true with the big bore kit Im having put in it though ;)

Who makes a big bore kit for this bike?
