Just taken the top end off. Found a small amount of piston waggle so I guess that could well be a worn small end bearing!
Removed the piston and that mostly looks OK - rings look good with the small nodule which keeps them from moving round all OK in both grooves! However, having said that the piston looks OK, I'm a it concerned about a bit of scoring on part of the piston!
I can also feel this scoring with my finger nail, so my plan is to have a rebore and upsize the piston and obviously re new the small end bearing!
I've heard there is a good place in Bristol - can anyone give me their details - Ta! Would they be able to sell me the bearing, and new circlips?
Have a look at this scoring - I guess you'll always find this on a well used piston!
