Hi,

 

I have a brand new Wiseco piston kit 513 64.50mm and I would like to trade for a 64.25mm kit. I thought my cylinders were over .25 but they are stock 64.00 and I don't want jump one bore when is not necessary.

 

thanks!

unfortunately prolly cost more in shipping than its worth loosing 1 bore size... But maybe you will find the right deal

Sometimes they don't clean up with only going .25 mm that's only .005 per side now if yours are worn at all that is now .004 or less per side if there is any scratches or not perfectly round or parallel worn harder at ports etc. One or both won't clean up.

 

If it were me I would just do the .5 mm over if I had to give the machine shop the pistons

 

I run into this when I bore cylinders blasters especially are always out of round and usually need to go .5 mm bigger

so I guess probably will be better go with these set then? The cylinder still good at stock bore but my F%$# caliper was out of calibration. Found some stock pistons and they fit very well in the cylinders.
