let the repairs begin!!!

[wrongway]

I have now got all the parts needed to fix my clutch (MT25 clutch spring) and rear break line (stock one rubbed through on the oil filter) as well as new tires front (stock size ME880) and rear (Darkside 205/60r16 altimax hp) I am also doing the much needed swing arm and drive shaft service.

Is there anything else I should look for or replace at this time when I have half the bike taken apart?

Did I see on here somewhere about a little ball bearing in the engine near the drive shaft that may come out and screw things up?

TIA,
