Anyone out there able to post up or give me some links to any files, jpeg, 2dcad, etc, that illustrate some 'typical' dome/squish profiles you'd see on small two strokes? 50 to 80cc. 65cc would be ideal. I've got a lathe. With a drawn template I could correct the original head in 20 minutes. I could use software, with bore, stroke, port heights, etc, etc, but it's just a vintage 50cc moped head I'm modifying to match a 65cc cylinder kit so im not after rocket science. engine is an "e50" Puch moped engine. Thanks.
