Transmission sprocket

The worn sprocket out of my 1964 CA95 engine is a 14 tooth. I see lots of 15 tooth sprockets for sale and read one post that said he liked the operation of the bike better with the 15 tooth. Does anyone have any experience?

Hi Gary. The transmission in the CA95 is geared with a top speed that isn't as high as we want in these modern times when people drive 50mph all over the place. The bike should have plenty of power to pull the 15 tooth. Running the 14 might give a tiny bit more acceleration but you'll really want more top speed with the 15 tooth. Also it depends on what you have for a rear sprocket. Count the teeth on the rear sprocket and report back.

Thanks a lot for your help. I counted 37 teeth in my rear sprocket.

No problem, glad to give some input. Ok great that's normal. Sometimes you see some old bikes with crazy big sprockets on them. 35-37 is about normal. The larger the rear sprocket the slower top speed you will have of course.
