Well the guy I sold my old 2000 400ex to decided he wanted more power so he brought it back for some work.. I put in a 406cc 11:1 Wiseco piston, stage 2 Hotcam, and a full xr400 gasket set. And before I put it together I went through the intake and exhaust ports with the dremel and some sandpaper to take out the casting marks and smooth it up, also ground down the welds inside the header.
I got it all back together fine, set the valves and started it up.. It ticks really loudly and doesn't sound good, but runs perfectly fine and starts up fine! I took the valve cover back off and checked everything out, but couldn't find the problem.. Now I don't know what to do.
Please help! It's a loud, consistent tick in the upper part of the engine.
Thanks.
