117 pistons

[Wookie3011]

Have the harley 117 TC kit on 110. Going to send the heads off this winter and wanted to CC them and set them up for current TTS150 Cam. In the process I want to get pistons that are lighter and perhaps better Compression for the cams. Is this a good idea knowing I've already set the rings to the jugs. Is this a waste?what would be the best. Thanks

You most likely will find your pistons in the hole, with the MoCo kit, usually anywhere from  -.008" to -.012".
With the piston geometry corrected, and a thinner head gasket, you may find you're where you should be compression wise, with no PMS.

Agree, the tts150 will be fine there.
