Never seen a 6400/6401/6421 with .325? couldn't even imagine some one converting it?

To answer your question, a different rim sprocket and bar for the kind of chain you are going to use.

was reading where someone bought a rental saw from a box store, figured they would have consumer type chain.

Never seen a 6401 w/.325 chain.  If someone had converted it from 3/8 to .325 all you would need is a 3/8 rim sprocket and a 3/8 bar.  Just thinking never seen a D009 mt roller tip bar in .325.  .325 could be done with a hard tip bar but what for.

You press the 272 coil winding onto the 6400 coil laminations armature frame minus one lamination leaf?

Correct,  remove one lamination.

Has any one tried the $5 Chinese coils yet to pull apart?

Title: Re: makita 6401

Mike, you mean pull apart and use as the coil portion on the Dolmar lamination?

Be interesting to test max rpm on an oem 272 coil and the Chinese version on the stock laminations. Wonder if they cut corners on the number of windings ?

That's what I'm wondering. If I'm going to butcher a coil why not try a super cheap one to start with. I haven't pulled the flywheel yet. Is the key made into the flywheel on those?
