Retracting pistons on 6 pot calipers?
Discussion
Just fitting new pads to the front of my TL1000r,which has 6 pot calipers on the front,done one side ok,three of the pistons on one side i just pushed in with a g-clamp,but the three opposite ones in the same caliper needing turning slightly to retract,the other side of the bike however is more of a pig,again three of the pistons on one side of the caliper just pushed in easily with G-clamp,the other three i tried to turn but they're not budging as easily,i don't really want to grip the pistons with anything that will scar the outside of them,anyone any tips?The pots are just round and hollow,nowhere to put allen key etc to retract them?

I think your right -- if you mark the piston surface you risk ruining seals for eternity. If they are that bad, pushing them back is not the answer.
They all need removing and the caliper given a light overhaul (clean basically) and new seals. Not difficult but tis dirty work... Force the piston out with compressed air from the hose side.
If these are the tokico (spelling?) like you get on '98-2002 Ninjas then they definately need an overhall.
I ended up doing mine twice a year (although I did ride it in winter and cover over 10,000 fast miles a year) Just to keep all the pistons moving.
It really makes a huge difference to their performance.

Beware, those of you with Brembo calipers - Brembo do not offer replacement seals, I don't think there are any aftermarket seals either, so if the seal is gone you'll need new calipers.
