Re: Shifter Kit Overall Good but 1 issue
What modifications? What issues?
If you install the kit exactly as the instructions say, you should have no issues. Sure, the chain may loosen a bit, so you tighten it. After the 2nd time retightening, I haven't had an issue since. (they also have a tensioner available) [and the stock HT chain likes to loosen a LOT, so that has to be tightened normally till it's broken in, so that would be nothing new]
I think europorsche's situation is a unique one, and I honestly wouldn't worry about this happening to you. The kit is well worth the money and is a nice piece of gear. Just take your time and install it properly and you should be good to go.
