Thanks. Looks like it will not be to hard to make. Cylinder clean up real nice. Now I need to get everything washed up. And order some parts.

Will a 395 piston work? Would there be any benefit to running that one over the 394 piston if it fits

To use a 395 cylinder on a 394 you need these parts . .  .

http://www.hlsproparts.com/OEM-Husqvarna-394-to-395-cylinder-conversion-kit-p/h40394.htm

The 394 impulse is internal whereas the 395 has a external impulse hose.

Best I can find the pistons will interchange somewhat

The bore and compression height and pin are the same.

The difference is that the skirt is 1mm shorter on the 395

Also for what it's worth - The 394 porting is the old style loop transfers with a single port on each side. All the transfer is up in the cylinder.

The 395 has quad porting more like a 372 but the cylinder base for 394/395 is the same. In other words there is no part of the intake transfer in the crankcase of the 394 or 395
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".

So the 395 jug has better flow then the 394 jug. Not so much asking about a whole conversion. But rather just the Pistons, it seems there is no real benefit the running the 395 piston in the 394 jug. Was thinking maybe they had a different compression
Height. Was also thinking maybe the 395 1.2mm rings would be better than the 394 1.5mm.

Not much real difference in power with them stock or ported. The 394 jug can be made to flow plenty.

Also will the coil from a 257/262 or a Jred 2095 work?

From what I have read on the other site the only real difference is the angle that the plug wire comes out of the ignition module is a little different.
