As you have seen the cleaner saw of your pictures is the new updated version of the MS 241 C-M. It has 200 g less weight and 0,1 kW more power compared to the old version. The easiest way to identify which the new version is, is the position of the diagnostic plug. On the old version it is on the left side from the air filter and on the new version it is on the right side of the air filter. There were also several other changes like aluminium screws for the crankcase, a complete new crankcase, other ball bearings and so on.

On the 241? I thought these changes were only on the 261.

Intresting topic. The bucking spike looks the easy way to tell them apart. That is likely for weight savings. I have stated it before, the 261 makes more power per cc. It has a stuffed crank and a carburetor and an air control device instead of using top and bottom of the one device. Wonder why they did not update the 241 to these features. Is the crank stuffed now?

There are no crank stuffers in either the 261 or 241. The design of the two saws are virtually identical.

These changes were first made on the MS 241 C-M around autumn/winter 2014 and later in 2015 on the MS 261 C-M. But the MS 241 C-M has no new chain sprocket cover like the MS 261 C-M and the changes between the 241 C-M and 261 C-M are different. (for example no new cylinder on the MS 241 C-M)

261c definitely makes more hp per cc ... I agree with that statement ! However just having built one recently I’m at a loss to your “stuffed crank “ statement ... crank looks identical to the 241c and 362c I also recently built (???) It my opinion that although all 3 saws have quad transfers the 241c flows from 1 large port and makes it way from there whereas the other 2 models have 2 transfers in front and 2 in the rear ... this design is superior imho !
