If I may,
1)Sprocket Specialist was way backordered (time was short). So I went and called Sprocket Center (888-265-2141).
2)I got the front in steel with the stock 14 teeth.
3)I got the rear in alloy with 49(2 extra) teeth.
4)Both are for a 520 size chain conversion. This gives you a lighter and less expensive chain option.(EK 520SRX(114 link) from BikeBandit.com)
5)Everything was in stock from AFAM and cost just shy of $90 for both.
6)The larger rear lowered the gearing for more acceleration. The lighter parts reduced spinning weight.
7)I did a couple other repairs and modifications at the same time so I can't give a controlled performance gain report.
8)It does have alot more punch and now goes to the redline for a higher top speed.
9)I guess I got the best of both worlds for once. 125mph-2nd gear pulls!
