I had it on my blaster for over 11 years, with no problems.. But i only trail ride and don't do a lot of jumping. I was also very paranoid about it, after every time i rode my blaster i had to triple check it to make shore i had no problems starting . The only thing i don't like about it is the chain adjuster, it was difficult to do. You have to loosen the 2 carrier bolts between the swingarm and the extension, then you have to reach inside behind the carrier and loosen the 2 allen head bolts on each side, and then try to spin the ??? (i dont know what to call it things)?? But first you must spray it down with some WD40 to clean the threads or you will not be able to spin the ??? (i dont know what to call it things)??
I don't think they make them like this one anymore..
