Re: what did you do to your motor bike today? On a ride to the store last night my chain almost skipped off the sprocket! So, I pulled a full link segment, as there was way too much slack with the new tensioner. Now it's looking good! I also put the pulley on the tensioner on the other side and reversed the brackets, so it's able to guide the chain on the sprocket, but without the angle. Very pleased with my new chain breaker - it's designed for 520, but works well enough to punch a pin out halfway, then I can use my standard bike chain breaker to push it through the rest of the way.
