| As a principle I would replace all the bearings if I was you.
I had my swingarm powder coatted black as well and replaced all the bearings in there too.
One tip on this though the needle bearings won't go in easy and if you hammer them in you are going to bugger them up. I figured a way by cooking the swingarm in the oven on 150C whilst leaving the needle bearings in the freezer for 24Hrs. Went in like a hot knife in butter though the missus asked what the heck I was cooking in the oven... |
