They work pretty well on a 395 but will not work on your 394 unless you buy the factory parts for a 395 intake tract. Around 65-85$. However HLS is out of the conversion kit and his been for about 3 months!

Who makes that kit Tim?  And does it take 1.5 or 1.2 mm rings, just wondering.

Every time I think 394, I think of the one I ran that had a "404" rim with 3/8" chain and bar. When you started in a cut, you would feel a big snap and a rough feeling. The saw actually performed very well considering the mismatch. It was soon corrected when brought to the attention of the owner who had recently bought the chainsaw.

IIRC the kit is from Hyway and it uses 2 x 1.2mm rings. HLS gives you the part numbers for the intake tract, you could check prices with your local Husky dealer or Spike60 on this site.

Doing the 395BB kit will get you to around 100cc.

I'll have to look and see if Caber makes 58 x 1.2 mm rings

Its not hard to convert a 394 to 395 but some other things need to happen as well.
Apart from the boot connecting carbie to cylinder, you also need the black plastic square bit to fit the 395 boot (to seal behind the cylinder.)
Other alterations are, the 394 throttle cable pokes through a small hole under the carbie, it needs the hole enlarged to let the cable come through and fit into the new arm on the boot. If you simply hook up the cable as is, it will pull off the plastic holder on the butterfly lever as its a little wide to line up straight.
Next problem is the 394 walbro won't work until it is externally pulsed on top and a tube run down onto the cylinder base.
Do these simple things and a conversion can be done for the better, you can also use the Tilly from a 395 which is already externally pulsed. Hope this makes sense as I have converted all my 394 racers to 95's but they all run 56mm  Mahle cylinders.
One last thing on BB kits for the 95, I have tested a few now and the rings are no good, I don't think Caber can supply better quality rings, all kits I tested had ring failures after not many hours work.

That's why I was looking for the thickness on the bb ring to see if I could find cabers.   Does stihl have a 58 m&m piston?  What's stihl rings thickness.
