After replacing my stock rear sprocket with a Yamaha one that has 2 more teeth, I noticed (after 10 hrs.) that the chain had worn right through the rubber in the back and was right near the aluminum of the guide under the rear of the swingarm. I like the new gearing and don't want to use a smaller front sprocket since it would wear itself and the chain faster and maybe have it's own guide problems. Is there an aftermarket guide that could be adjusted for angle to adapt to the new chain angle with the larger rear sprocket?
