Putting a 51 tooth rear sprocket on my 06 yz450f. I have a new Renthal 520 chain that has 120 links including the masterlink. The stock chain came with 114 links with a 14 tooth front sprocket and a 49 rear. So when I put my new 14 front sprocket on and my new 51 Rear how many links will I need to take off by going up two teeth on the rear?..... And on more thing "I dont have a chain breaker" and was wondering what other way is there to cut links out? Need some advice!!!
