Gearing down front sprocket, without new chain
Its almost riding time and I am just starting to make a list of things to do before summer starts. I have an 02 954rr with 8000ish miles on it, and I want to do lower the front sprocket to a 15 tooth, which seems like its the accepted standard here.
My question is, I was always told its bad to change just the sprocket without a new chain... I am extremely cheap and saving 180 dollars here would allow me to do some more work to my dirtbike. Plus its a ton easier to just change the front sprocket, than to do the whole chain.
I think its a pretty basic question, pretty univeral too. At 8000 miles my stock chain and sprockets look fine, they would probably last until 15,000, but they are not exactly new. I only want to do this mod because the CBR is geared way too high stock.
Thanks for all of your replies.
