I was looking into buying a chain tensioner, then I came to the conclusion that I'm not going to pay $50 for something I can make myself in about 20 minutes. Especially after hearing alot of bad things about them(spring and rolller breakage)[img]i/expressions/face-icon-small-mad.gif[/img]. I just need to know how it goes on the swingarm. Does it go on the top of the swingarm w/the roller below the chain pushing up, or does the chain go below the roller w/the roller pulling down on the chain? Thanks. Lata.
