Hey everyone...I'm new to the board and dirt bikes in general. Have mainly been a road racer until getting into supermoto with a CA street-legal 450X. I'm in the middle of a top-end rebuild and wanted to get some opinions on some wear marks on the connecting rod. See the below pic: Looks like some of the plating is wearing off on the bottom end of where the pin goes through. Don't know if this will require a new rod or if it is normal. The inside surface is really nice & smooth, the pin fits well...maybe a little loose but I guess loose engines run good, its just the wearing discoloration that really caught my eye. Also what do you guys recommend to clean up the head? Or any other servicing to it? I know to clean off the gasket gunk...just haven't gotten around to it yet. The cylinder looks really good, still has all the cross-hatch marks and a few light vertical wear marks. Do you usually hone the cylinder regardless of its condition just for good measure? Thanks in advance.
