chain tensioner upgrade
 
Getting ready for a chain tensioner upgrade on my 80SC. I just replaced the chain ramps and noticed that on the left side the lower chain is loose. I can easily lift it off the ramp a 1/2 inch with no effort. What are your thoughts?
Do I need to replace the chain or will the new tensioner fix this.
Also the top of the chain is very tight as well as the right side.
Thanks http://forums.pelicanparts.com/uploa...1202957166.jpg

A picture showing the top of the tensioner would be helpful. Would like to see if it is collapsed.

I would like to know if it is collapsed also.

Did mine today...looked same way; reason? Tensioner collapsed.. same side too!? consider yourself lucky like I do..could have been much worse

Is your engine at TDC? I forgot that little detail when I opened mine up last weekend and the left side cam wanted to rotate CCW (depends on crank position of course) hence no tension on the bottom portion of the chain. I had to put a wrench on the cam nut and turn it CW to give the chain some slack while I installed the tensioner.
