17 tooth like new 14 stock about 50% used

[German Shepherd]

I have some sprokets from my banshee. I have the stock 14 tooth that is about 50% left wear. I also have a 17 tooth that I drove 2 times with. I went once for about 3 minutes at night on the streets after I installed it, Then I took a long ride and toped my machine out on the highway like road that I later was fined for being on. With the 14 tooth I heard but am unsure that it will go 73 mph. The 17 tooth will barely fit the stock chaine and sproket but It will fit. The banshee will also go alot faster. 1 st gear felt like 3rd. and 4th felt alot faster then 6th. I also have the stock plastic reeds in very good condition. I dont know if they are worth anything but I will take what I can get.
