Hey all,
As you know, the chain wearing into the subframe is an issue on the KX500.
When I bought mine, the prior owner had already installed this set-up. It's simply a piece of plastic
cut to the shape shown and then simply screwed into the chain guide. I know, I know . . . I thought the same
thing when I first saw it- "that's not gonna last for crap." But it's worked perfectly and hasn't
been a problem at all. Even with that one screw missing. Hooray for cheap and easy ideas that work!!
The marks on the subframe are from the prior owner of this particular subby that I recently had bought on ebay.
On the rear guide, you know how that little block is about $30? I just took some scrap round stock Delrin that was
laying around, cut it to fit, drilled the center and voila!
