This past year I had you do a 144 Big Bore Kit for my 2002 YZ and it has been nothing short of awesome!!! :) The question is I know where I can get a 3mm stroked crank very reasonably and I was wondering if you could do the crankcase clearancing and any other modifications that would be needed to accomodate the longer stroke, and if so, how much would it cost me?
All we need to do is bore cases and re-cut the head. My 58mm piston is longer to accomodate strokers. Prices are on my web site.
PS send your cylinder in too for free diamond honing.
