Been a while but I have been slowly fixing up the KDX I bought and letting my hand heal from my previous outing. I have run into what I think is my last significant repair and have found it to be a bigger problem than I thought. The previous owner of this bike pretty much rode it into the ground.....broke the rear chain guide so he removed it altogether and then just rode the heck out of it until the chain was so loose (even with the wheel all the way back) that the chain began slapping wildly into anything and everything in its path. The result was the front chain guide apparently took as much as the top bolt could handle and snapped off. I took the bike to a local Cedar Park machine shop and the guy attempted to remove the bolt but was unable..and thus tore up the threaded hole a bit in the process. I need a professional to have a look at this thing to see if the bolt can be removed without causing anymore damage so I can put the guide back on. Otherwise I'm going to have to ride without a front sprocket cover/chain guide (I don't like that idea...shoestrings and things tend to make their way into that area very easily). Anyone got any ideas or suggestions?

If your talking about the flat stock deal that is to "guide" the chain and protect the cases, that's one thing. But if your looking at a deal the "covers" the CC sprocket....most of us remove them so that mud does not collect. I can see the need for the case saver.

And any machinist sould have been able to remove a bolt, if it needs to be welded...K+K welding off of S Congress.....

can you post a pic....?

go the the hardware store and get "easy outs" and a drill sized to work with the correct easy out.

drill the hole and insert easy out and back the bolt out.

sounds easy.. but can be a pita. sometimes you will need to re-thread the hole

You if you got the new chain and sprockets as well as the lower chain guide.. you could go with out the front guide. just make sure your chain is not worn beyond service limits and you keep the chain at the correct tension.


here's a nice little link to using an easy out

Yep.... there should be a "case saver" mounted there.

Seems odd that a machine shop could not remove the busted screw....

Any decent machine shop can fix that. Easy outs are great when they work, but if they don't they can break off. You then have a real PITA since the Easy Out is hardened tool steel and very hard to drill out. I'd take it to a good machine shop and let them fix it the best way possible (either getting the bolt out, or worst case getting it out and heli-coiling it).

There's a good little machine shop and engine builder off Burnett Road in that little industrial complex just North of 183. Its the one with the light blue buildings, with the kayak rental place on the end. He's back down that row on the right. The guy builds everything from big blocks for Corvettes and Shelby Cobras to bikes, and they are very bike friendly.

Well I was looking for something close to Leander when I was informed of the machine shop I went to off 183 and 1431. I kinda got the impression by looking at the broke down cars in front (old 74 rusting plymouth satellite and an old BMW 3 series) that they probably weren't that great...lesson learned. I agree that any machine shop should be able to get that bolt out because I have seen far worse problems get repaired. Guess I'll take it down there and see what they tell me....helicoiling doesn't bother me as long as it works.

shoe laces? :-) I would recommend at least a cheap pair of motocross boots or your feet could be recovering next :-)
