I was always told the in hole and wrong hole :msp_scared:

The very nice stock cylinder porting - but "strangled" more than usual at both ends, compared to what the cylinder is good for.

Yes it had some widening done on the in and ex & the timing changed a lil. nothing done to the transfers.
But this is a whole different cyl. The intake was already where it needed to be on the other one so I couldn't use it to cut the band & drop it. It would have had the intake opening waaaay to early.
I had to drop everything to run into the school & have a chat. I'll try to get this done & a vid up before everybody gets home & I have to have a heart to heart.:msp_wink:
I do have some pics of the porting if anybody wants to see them...
First the before pics.

I don't think that cylinder needs a lot of work inside the transfers, but otherwise I am not the one to judge. As you surely know, I do not port saws - but that doesn't keep me from learning a few things here and there, mostly from my brother (no, not brother Wendell):msp_biggrin:.

if it turns out anything like that 390xp you did he will be real happy.:msp_biggrin:
I hope it turns out better, I've come up with some other things to try. Then again I may be hunting up another top end:msp_scared:

Certain parts of the rotating assembly have lost a combined weight of 46grams.:msp_wink:

In this case, the in and the out hole is correct, but it isn't only the hole on the "out" side, it also is the size of the muffler (really too small for a saw that size).

eh live en learn, if something goes wonky ya know what not to do next time. on a different note if you can get the gains out of the 385xp like you did on the 562XPAT and 576XPAT you did for me (which i think i may have to pry from someones hands:msp_wink: at a certain GTG) Buffhunter will be impressed greatly. And that is why your my #1 saw porter/modder. Kudos bro keep up that awesome work.
Also lets hope this saw can put some times down in the test log when its done to show a certain dolmar its place:msp_biggrin:

I suspect the 385 is easier to get gains out of...
