Re: Kit Longevity Updates...
I just unscrewed the stock wire and replaced it. I hear some kits are glued and you have to dig it out, but it is still a great mod even if it's glued.
The HD chain is the first mod any motorized bike needs.
Makes it so much more reliable, less drag and noise as well (depending on your particular tensioner setup)
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
