Hi all,
I am in the process of a rebuild on a 2003 bullet 500, I have had a previous post on here regarding the subject which started with a soft seize and piston slap in the original motor. I then had massive issues getting off the head which had been 'glued on' somehow, this resulted in a broken crankcase, (long story short), I now have the bike back up to requiring just the top end putting back together.
I have had the barrel bored out to 0.20 oversize and picked up an oversize piston to suit from Price parts in the UK, the make of piston kit is JP from Australia. (Tho original bore had marks from the soft seize).
The concern I have now is that the new piston kit had a tight wrist pin on fitting, once in the rod it is tight to the point where I have to move the piston itself manually on the rod, it will not rotate under its own weight on the small end.
The small end in the rod looked good with no burrs or marks.
Is it normal to have a tight fit from new like this...I did have the barrel on and when spinning the motor with my hand it all moved smoothly.
Any input welcome please?
