sandblaster:
And, it looks really cool too 8-)
That being said I've been looking at the pics a lot since you posted them yesterday it sounds like the right approach.
I just don't see a downside to it, said the blind man..
Motorrad:
okay,. keep in mind this is on stock hight jug. and dont judge the CRUDE work. just playing and testing at this point, and the dremel and fast cuts is the easyest way to do that right now. once figured out, angles etc will all be cut on the mill...
bottom skirt cut closes 2mm before the transfers open..
windows start to open 1.5mm after transfers open..... they arnt fully open untill BDC..
the tape line is to cover where I cut further down the piston to start... decided we dont need to go that far. ??
Here is BDC. note, They window doesnt go all the way to the bottom... in theory, to keep from starving the floor ports, and the booster ports.. (also need that hight, to keep them from opening before the transfers). hard to tell in the picture.. but when FULLY oepen at bdc. the bottom of the window is half way up the side boosters...
here they are just starting to open... 1.5mm AFTER the transfers have opened..
conbread:
motorrad, i have another piston if u end up needing one to recut or whatever just let me know and ill send it to you..

1. not opening the piston window's till right AFTER the transfers open. (on down stroke)..
2. Closing the bottom of the piston cut right BEFORE the transfers open (on down stroke)
Playing some more.. I can get .839sqin of area (.419sqin per port) all without them opening untill the transfers are already open.. am I being a bonehead and missing somthing by having them open after the transfers?
