ST4s-14 tooth Front Sprocket

I put one in tonight.
Went from the stock 15 tooth to the 14 tooth. And all the claims I have read about doing this are true.
Runs smooth and easy. Bike should've come this way.
A recommended upgrade, IMO.

Ride safe.

Makes sense. May actually help highway mileage or at least cut back on the number of top gear downshifts.
How did you make out with the chain length? Mine has 4000 miles on it and it has loosened enough to require a couple adjustments. Did you have enough adjustment left to get the chain tension without pulling links?

Never mind. Put on a 14T this weekend. I can see where the new ratio's could definitely improve mileage if you used 6th under 80 mph.

Couple of interesting observations. Had to loosen the clutch slave unit enough to pull it away about an inch to get the stock 15T out. Not an issue with the 14T. Goes in and out easy. The bad part was it had to.

Seems the Sprocket Specialties sprocket I had didn't have clean threads all the way through and one of the soft stock bolts for the retaining clip snapped off which pretty much screwed riding for the holiday as I didn't think I could find much of a metric bolt selection here in SW Minnesota.

Just for laughs tonight after work (the only bike dealer in town closes at 5:30) I stopped by the local Ace-Tru-Value hardware store. What happened there was nothing short of a miracle.

First they had the most complete set of metric fasteners I had ever seen and I owned Jap bike dealerships. Had six different options in 5mm threads with an 80 pitch and 16mm length - 3 different heads and two different metals to choose from. Used one of the stainless allen head replacements to do what I should have done in the first place and chased the new sprocket's threads from both sides.

As I finished that up I was looking for a drill bit and maybe a stronger drill motor than I have and alongs comes "the helpful hardware man". The guy wound up taking the sprocket in back with a new bit and drilled in to the old snapped of bolt head screw which forced it out without even needing an easy out. Thirty minutes later the ST was out on the road loving life again.

For a grand total of $2.00 I felt so guilty I spent a whole $2.79 on a very nice t-handle at the perfect length and fit to torque the new bolts perfectly. Why didn't I think of those guys on Sunday while they were still open?
