my stockers got 19K on it and still seems to have some stretch left to it even after some heavy-duty dyno tuning... I've been eyeing the 520 Kyle conversion as a winter mod tho...bladeleeder : So why did my stock D.I.D chain only last about 12K miles? I clean it regularly and try to make sure it is not too tight, although I'm sure there have been several times when that was true.
Liability and intended use.bladeleeder : After checking on several manufacturers websites, they list the 520 chains in their top models as good for 750cc max engine size.
So what gives?
