Front Sprocket

Recently replaced the front stock 15 tooth with a 16 tooth....

It makes a world on difference on the hiway.... I would recomend it to anyone who spends more time on Interstates.

Do have a question though.... those of you that have gone with the 16 tooth, have you noticed an incease in noise in the chain and front sprocket ?

The stock 15 tooth is rubber dampened where as the after market 16 is not....

Can anyone confirm and or comment, is this is the source of the noise? The chain seems to be lined up OK .....

Thanks

Haven't noticed any extra chain noise on mine. You did give a lil bit more slack to the chain when you rechecked the chain adjustment? The 16t sprocket is a bit bigger in diameter than the 15.

I just thought of something else. You did put the supplied washer on the backside to shim it out? If you lay the factory sprocket on a flat surface with the outter side facing upwards, you need to find the correct side of the new 16T sprocket that will match as closely as possible the offest. One side will sit higher than the other.

I was going to tear it down tonight to inspect, as you say the sprokect may need to be reversed.

You were right on about the sprokect, it needed to be turned over, however the according the instruction provided, the bushing (spacer) is supposed to be on the out side.

I laid the two sprockets side by side and they line up pretty well right on with out the spacer on the inside.

So I will try it and see what happens...... I am guessing there are different sprockets, all depends on the manufacturer...... (I am using the studebaker)

Hey if it is still noisy I will order one from a different supplier.

Excellent. Yeah too many different suppliers with different makes. Ours came with no instructions, we had to go about it just like you did till we got the offset right. If it matches up good, then definately follow instructions and put washer on outside.

I was thinking this might be one of my first mods on my 08... am I correct in assuming the highway mpg might be improved, as well? Also, I'm thinking it will give a little more reach in first and second gears in town driving?
I don't see any downside, unless you spend most of your time going up and down hills off road.
What am I missing?

That's pretty much correct 'hornet'. It will help some with gas, in terms of dropping your rpm's at any given speed by about 500. You do have a slight more reach in the lower gears, but not as much as you might think. The big advantage is on road cruising in fifth. If your not doing any off roading and not pulling any hills I think you will find the 16 a good farkle.
