Sprocket
Hey Van. Yes you can narrow the teeth. Carefull not to SHORTEN them though. You will need the length of each tooth. Carefully grind on both sides evenly. I have done this to make BMX chain work. It works, just leave enough material so that the chain rests on the original center of your sprocket. You will be tempted to shorten, but don't do it. Just keep narrowing til the chain rests down without binding. If you go to a wider chain you will add weight & it will have play on your rear sprocket 420 will still work.
