Who cares?
Seriously......
Go cut some wood and quit playing with your peters.
I care.... seriously.
Sorting through all the crap is just an inevitable part of the process, still worth it for me at this point, I don't port 5 or even 1 saw a day so I'm not so jaded... yet...
I'm pretty comfortable with 4 strokes but still early on the learning curve with 2 smoke saws so I absorb everything I can.
I've struggled with all the compromises of 'where to put the power' in most every performance motor I've ever built, 'more grunt' or 'more peak', or...
That dyno graph I put up in the other thread was a bike motor I was building specifically for a big fat midrange, massive drive to slingshot out of the corners on twisty roads.
I don't like peaky power for that, it bogs and then spins the rear tire up when the power hits. Different than saws, I know...
Obviously you try the get the most power overall out of a particular motor but it seems ultimately the compromises push toward either a lower peak power in a broader range or higher peak in a narrower range. With a 4 stroke that's due to lots of things, among them the relationship between cam lift, duration and overlap.
Then you can also move the power band around some without affecting it's peak or width quite so much by things like cam timing, intake tract lengths and fuel/advance curves. I'm sure much of this could be paralleled to 2 stroke port timing and transfer parameters but I just don't quite get the big picture... yet.
So here I am...
I also was really interested in the other thread because ms460 port timing numbers were involved in the first post and I just did one that I'm not quite happy with and am not sure what direction to take it from here. Did leave myself some wiggle room.
Was pretty disappointed when the thread almost immediately went to hell...
And my firewood season just ended abruptly with 3 feet of snow the other day... and my shop is freezing...
