250-500cc Squish numbers on a 360 with KTM rod kit

Right just out if curiousity and had ten mins to kill.
Heres the head

Hard to picture right as its soo shiny! Never had a head this clean i know some people post up pictures and their cylinders dont look run but mine have and its got 37+ hours of hard use on it.
Heres the piston few more hours on it the scavenging marks have been coverd up with oil as im running 33:1 now i think im a tad rich on needle= gunna leave
And i think by the dry spot right in the middle im a smidge lean on power jet = 1/4 turn richer.
What you guys think? Im open to criticism.


P.s. That is my decomp mod infront of the spark plug.

Yes, you can just make out the scavenging developing. I'm leaving it alone for now, perhaps open it back up after ~ 20 hours or so for a curiosity look-see. I'm running the Castrol synthetic at 32/1. Looks like I'll be good on regular pump gas!

Really clean looking burn there Juicypips!

i wouldnt worry about it. if it isnt loading up and its revving clean its not too rich. by the looks of it, things are fairly close. plenty of oil, leave it be!

Ive put the pj a 1/4 richer all the rests the same, cheers guys.

smart move, i like to run the pj richer until i get some four stroking in the mid or top, then back off a hair. alwyas seems to happen n the mid first tho. im really close to trimming my orifice tube or running a slightly shorter one.
