I have run into the same problem. The circlip holding the idler gear came off an the bearing behind this has been destroyed.
Anyone know where I can get a replacement bearing? And does the engine need to be split to fix this or can I get away without doing this??
Can anyone point me in the right direction for some replacement parts for a PSTO 160CC??
Was riding the other day and it locked up. Looks to be a gear behind the clutch basket.
Something in Australia would be preferable.
