Hopefully soon this will be my first attempt at top end modifications.
Squish: Piston was initially dead even, but I put a spacer in there and it measures just shy of 1mm squish. Figure this will be okay with a stock head.
After buying and breaking piston rings for a different airsal piston I just threw the puch piston in it. It seems to be a really good fit but might be a little loose in there. ...(I know what I did wrong with the rings. I forgot to file the gap a little. they were on there but couldn't get it into the jug. was impatient....)
At TDC you can also see the piston flaps stick out a little into the intake. Assuming I should cut that back. Any advice here?
At BDC it looks really good and have a good gap to widen the exhaust port. Transfer ports match up perfect.
I will probably just try to get it running first before I start drilling stuff out but still want to post this.
1.) Piston intake window.... Wouldn't air be pushed out the window during the compression cycle also? .. I guess that is what reeds are for? Basically, should I put a window? Any design recommendations?
2.) Anything else I should consider doing? I don't want to do anything crazy just yet but is there any other basic things I should think about when it comes to cylinder modification. Will this (puch piston, etc.) even work
Eventually I will get into the transfer ports
