Ever deal with Wiseco pistons
Initially bought one from DD for this build. Was 066, but the skirts were just as narrow as the stocker. Was waiting on Dave for version 2.

Have a buddy close thst has the blue skirted 288 wiseco. It has the 1mm stainless ring that chews up Stihl oem plating though.

Took 75 off base and 30 from band. Was enough to tuck the bottom ring in the intake roof at BDC.

Im at 100 ex and 84 intake.

Squish came in at 15, so I’ll be sanding 3 more thou out of the band.

Look at the width on that 288! I have heard a lot about doing these but looking forward to how the super wide turns out!

I fell like this thread is going to make me do this to my 660 clone at some point.

would love to see a video of this thing running when you get it all together.

Band cleaned up OK. Not the prettiest, but pretty isn’t always fast.

Be a while before it runs, as case halfs out for powder still.

The stock 66 piston just covers the port, but id be a bit nervous running it, though the wings might hold it together. Squish around 19.
