Not sure if this is where to post this but...I have a 1998 RM125 that keeps losing the top end. I've read about relieving the exhaust bridge .002/.004, but haven't done it on any of these rebuilds. How do you do it? With a dremel and a cratex wheel? How do you check it? With a surface plate and an indicator?

Thanks...

Already tried that. Kinda lookin' for someone that's done some engine work that could help me out before I put it back together just for it to seize up again cause the exhaust bridge is not relieved.

all you need is a small straight edge to put through the cylinder from top to bottom across the bridge and you can see how much it needs grinded. dremel will work fine. make sense ? if it has steel sleeve you wont have a problem doing it now. on a plated jug you would want it relieved before the plating was applied. might check your service manual. sometimes they show how to do it. honda books usually do anyways
