Install a 16 Tooth Front Sprocket - Page 5

Gadzooks Mike · 05-15-2007, 11:02 AM

So did mine, Jordan, but that's not the point. To be able to run a 60mph and still have some play left in the throttle is nice. To be able to get up a hill in fourth at a decent speed without shaking myself off the bike will be nice, too.

Jonathan, I'm hoping to take a bit of a longer lunch hour today... heh heh

Gadz,

But wait. I never need 4th uphill unless the incline is super steep, and then running at 60 is nothing. The engine has quite a bit of rev left in it.
I never get any shaking at all. Once I hit 75Mph stock on this bike, it pushes hard to try to reach 79mph. at about 77-78 there is a little shake, but not much at all.

The only problem with 77-79Mph is the high revs, and nothing left when gunning it full throttle.
I think everyone's bike runs different, and It might have to do with the fact that I did the airbox removal, stock filter bolted directly to the carb, and rejet going on, but my bike seems happy at 65 for sure with quite a bit of oomph still left.

I'm wondering now that I ordered the 16 toother with rubber, what the deal will be.

Well, there you go. Your bike is much faster than my bike.

you have a part number on that?

As I stated before, this isn't a mod done for a massive increase in top speed. It lowers cruising revs throughout the power band and rpm range in all gears. I've also noticed an increase in my fuel economy of 4-MPG.

In the post that you are replying too, you misunderstood my point. I wasn't raving about the amazing power at 55-60mph, I was trying to infer that the largest impact of this new sprocket comes in that area, where most of us spend our time anyhow.

Jordan310 · 05-16-2007, 03:45 PM

I usually end up averaging about 65 Minimum to 77Mph on the 4 lane freeways.
I really hope this mod adds some needed ease to reaching top end for the bike.

Im also wondering, .. does slack in the chain have much to do with the response of the bike in reaching its needed gears?
Will a decrease of slack improve the bikes oomph?

:??:

That's a big N-O. There is an optimal tension that your chain needs to be set to in order for the bike to function properly.
Too much slack and you'll notice a decrease in rideability. Too tight and you'll be putting too much tension on the chain and the drive components.

Loosening your chain will not give any boost to performance. Adjust your chain per the service manual and you'll be good to go.

Did you get a part number on that OEM 16 tooth sprocket yet?

Jordan310 · 05-16-2007, 05:33 PM

K.

Ill look for that part number and post it when I have it.

Just for future reference, the stock gear ratio is: 2.73

The gear ratio with the new sprocket is: 2.56 (The same as the stock GS500)

(2.56-2.73) / 2.73 = 6.23% change is gear ratio

Just ordered a JT 16-tooth front sprocket from BikeBandit.com

Hoping to get it installed in a week or so.
