New tires, sprockets and chain. Went from 20's to 18's so i came up a tooth on my front sprocket. The old front sprocket could have been used as a ninja star. Seriously the worst sprocket i have ever seen. No wonder the previous owner got some case damage. Well I made sure that would never happen with a guard but with the bigger sprocket the clearance is like a 1-2mm. Does anyone think this is too close?
