I'm getting some dimensions off of my "07" so Mark Krieger can look into producing a beefier case saver for the KLX. I would assume the newer bikes have the same cases, but thought I would put this out and see if anyone can confirm or deny it. Also looking to see if anyone with a 15 tooth sprocket can measure the radius , center to outside of chain.
Thanks,
Dan



I don't like the pinch point this one creates. You could really get a rock jammed in there.




The prototype I made has taken a few hits.

 

because of the complex shapes and offsets of the case, I was just going to reinforce the plastic sprocket cover somehow, probably on the back side.

ideally I'd like the gaurd to rest against the case somehow so the pressure is off the mount bolt castings. Tore them out on other bikes that had solid guards.

 

the case as far as i can tell between my 07 and 09 are the same,
the ting i look at an would wonder if it coul be used is that open bolt hole above th CS and see if it can be used to wrap up there more or something

 

Dan,
I have a 15T and will try to get dimensions, but it will be a couple days. If Krieger would like a stock case saver to work with, I'd take mine off for a while and send to him.

 

dan, what about the 3-bolt OEM guard on the bottom? Mark and I talked about this over the last few days. I'm concerned that the armor piece would have to be a rather large, close fitting chunk of material that really hugged the countershaft sprocket to be really effective. If you don't, just as dan mentioned, there's a decent chance of the armor piece being more detrimental to catching a rock or debris. Also, if the piece isn't well contoured to the sprocket, it will jam up a chain that comes loose in the worst of circumstances.

I'm thinking the smaller, steel, OEM unit(s) might act as a bit of a damper if something lodges in there...kind of like how a car is made to collapse and absorb energy in a wreck rather than just be a solid, hard, unyielding object. If you're going to have a replacement, I'm of the opinion that it has to follow a good deal of the sprocket's arch and follow it fairly closely to be truly effective. Otherwise it's more likely to just pull those little 6mm bolts out and/or crack the case...the very thing you're trying to avoid.

I'm no engineer, and these are just observations I made while changing out to a 13T sprocket yesterday. It's funny...I'd not really noticed before that there's also a 3-bolt OEM steel piece of light armor that wraps under the countershaft sprocket.
