Was planning on moving up to a 15/52 with this change out but had a small surprise when I took the front sprocket off.
I thought,(my mistake) that I had a 14/50 stock from prior owner. Well I thought wrong as it turned out to be a 15 tooth front sprocket.
I had a nice 52 rear ready to install but I did not want to go any lower. In fact I wanted to go higher but decided 15/50 was going to be fine.
So on Monday I ordered a 50 tooth rear sprocket from Lytle Racing Group in Arizona.
Today is Wednesday and the new sprocket was delivered around noon time.
Very good service from both Lytle Racing and Priority Mail from the USPS.
Now if I just get the new keeper.
If anyone is looking for a JT 52 rear sprocket let me know. I may post it in the classifieds in a few days after I see how the new sprockets and O-Ring chain work out.
